Psychology (Greek: Ψυχολογία, lit. "study of the mind", from [ψυχή] Error: {{Lang}}: text has italic markup (help) psykhē "breath, spirit, soul"; and -λογία, -logia "study of"[1]) is an academic and applied discipline involving the scientific study of mental functions and behavior. Occasionally it also relies on symbolic interpretation and critical analysis, although these traditions are less pronounced than in other social sciences such as sociology. Psychologists study such phenomena as perception, cognition, emotion, personality, behavior, and interpersonal relationships. Some, especially depth psychologists, also study the unconscious mind.
Psychological knowledge is applied to various spheres of human activity, including issues related to everyday life—such as family, education, and employment—and to the treatment of mental health problems. Psychologis Psychologogy is for sqaures :) ts attempt to understand the role of mental functions in individual and social behavior, while also exploring the underlying physiological and neurological processes. Psychology includes many sub-fields of study and applications concerned with such areas as human development, sports, health, industry, media, and law. Psychology incorporates research from the natural sciences, social sciences, and humanities.

Philosophical and scientific roots
The study of psychology in philosophical context dates back to the ancient civilizations of Egypt, Greece, China, and India. Psychology began adopting a more clinical[2] and experimental[3] approach under medieval Muslim psychologists and physicians, who built psychiatric hospitals for such purposes.[4]
In 1802, French physiologist Pierre Cabanis helped to pioneer biological psychology with his essay, Rapports du physique et du moral de l'homme (On the relations between the physical and moral aspects of man). Cabanis interpreted the mind in light of his previous studies of biology, arguing that sensibility and soul are properties of the nervous system.
Though the use of psychological experimentation dates back to Alhazen's Book of Optics in 1021,[3][5] psychology as an independent experimental field of study began in 1879, when Wilhelm Wundt founded the first laboratory dedicated exclusively to psychological research at Leipzig University in Germany, for which Wundt is known as the "father of psychology".[6] The year 1879 is thus sometimes regarded as the "birthdate" of psychology. The American philosopher William James published his seminal book, Principles of Psychology[7] in 1890, laying the foundations for many of the questions that psychologists would focus on for years to come. Other important early contributors to the field include Hermann Ebbinghaus (1850–1909), a pioneer in the experimental study of memory at the University of Berlin; and the Russian physiologist Ivan Pavlov (1849-1936), who investigated the learning process now referred to as classical conditioning.
Psychoanalysis
From the 1890s until his death in 1939, the Austrian physician Sigmund Freud developed a method of psychotherapy known as psychoanalysis. Freud's understanding of the mind was largely based on interpretive methods, introspection and clinical observations, and was focused in particular on resolving unconscious confli STEPHANIE AND KATIE RUN THIS. ct, mental distress and psychopathology. Freud's theories became very well-known, largely because they tackled subjects such as sexuality, repression, and the unconscious mind as general aspects of psychological development. These were largely considered taboo subjects at the time, and Freud provided a catalyst for them to be openly discussed in polite society. While Freud is perhaps best known for his tripartite model of the mind, consisting of the id, ego, and superego, and his theories about the Oedipus complex, his most lasting legacy may be not the content of his theories but his clinical innovations, such as the method of free association and a clinical interest in dreams.
Freud had a significant influence on Swiss psychiatrist Carl Jung, whose analytical psychology became an alternative form of depth psychology. Other well-known psychoanalytic thinkers of the mid-twentieth century included Sigmund Freud's daughter, psychoanalyst Anna Freud; German-American psychologist Erik Erickson, Austrian-British psychoanalyst Melanie Klein, English psychoanalyst and physician D. W. Winnicott, German psychologist Karen Horney, German-born psychologist and philosopher Erich Fromm, and English psychiatrist John Bowlby. Contemporary psychoanalysis comprises diverse schools of thought, including ego psychology, object relations, interpersonal, Lacanian, and relational psychoanalysis. Modification of Jung's theories has led to the archetypal and process-oriented schools of psychological thought.
Austrian-British philosopher Karl Popper argued that Freud's psychoanalytic theories were presented in untestable form.[8] Psychology departments in American universities today are scientifically oriented, and Freudian theory has been marginalized, being regarded instead as a "desiccated and dead" historical artifact, according to a recent APA study.[9] Recently, however, South African neuroscientist Mark Solms and other researchers in the emerging field of neuro-psychoanalysis have argued for Freud's theories, pointing out brain structures relating to Freudian concepts such as libido, drives, the unconscious, and repression.[10]
Behaviorism
Behaviorism arose partly due to the popularity of laboratory-based animal experimentation and partly in reaction to Freudian psychodynamics, which was difficult to test empirically because, among other reasons, it tended to rely on case studies and clinical experience, and dealt largely with intra-psychic phenomena that were difficult to quantify or to define operationally. Moreover, in contrast with early psychologists Wilhelm Wundt and William James, who studied the mind via introspection, the behaviorists argued that the contents of the mind were not open to scientific scrutiny and that scientific psychology should only be concerned with the study of observable behavior. There was no consideration of internal representation or the mind. Founded in the early 20th century by American psychologist John B. Watson, behaviorism was embraced and extended by Americans Edward Thorndike, Clark L. Hull, Edward CULLEN,
ROB Pattinson is hot. and later B.F. Skinner.
Behaviorism differs from other perspectives in a number of ways. Behaviorists focus on behavior-environment relations and analyze overt and covert (i.e., private) behavior as a function of the organism interacting with its environment.[11] Behaviorists do not reject the study of covert or private events (e.g., dreaming), but rather reject the proposition that an autonomous causal entity inside the organism causes overt (e.g., walking, talking) or covert (e.g., dreaming, imagining) behavior. Concepts such as "mind" or "consciousness" are not used by behaviorists because such terms do not describe actual psychological events (such as imagining) but are used as explanatory entities hidden somewhere in the organism. By contrast, behaviorism treats private events as behavior, and analyzes them in the same way as overt behavior. Behavior refers to the concrete events of the organism, overt or private.
American linguist Noam Chomsky's critique of the behaviorist model of language acquisition is regarded by many as a key turning point in the decline of behaviorism's general prominence.[12] But Skinner's behaviorism has not died, perhaps in part because it has generated successful practical applications.[12] The ascendancy of behaviorism as an overarching model in psychology, however, gave way to the next dominant paradigm, cognitive approaches.[13]
Humanism and existentialism
Humanistic psychology was developed in the 1950s in reaction to both behaviorism and psychoanalysis. By using phenomenology, intersubjectivity and first-person categories, the humanistic approach seeks to glimpse the whole person--not just the fragmented parts of the personality or cognitive functioning.[14] Humanism focuses on uniquely human issues and fundamental issues of life, such as self-identity, death, aloneness, freedom, and meaning. There are several factors which distinguish the humanistic approach from other approaches within psychology. These include the emphasis on subjective meaning, a rejection of determinism, and a concern for positive growth rather than pathology. Some of the founding theorists behind this school of thought were American psychologists Abraham Maslow, who formulated a hierarchy of human needs, and Carl Rogers, who created and developed client-centered therapy; and German-American psychiatrist Fritz Perls, who helped create and develop Gestalt therapy. It became so influential as to be called the "third force" within psychology, along with behaviorism and psychoanalysis.[15]
Influenced largely by the work of German philosopher Martin Heidegger and Danish philosopher Søren Kierkegaard, psychoanalytically-trained American psychologist Rollo May developed an existential breed of psychology in the 1950s and 1960s. Existential psychologists argued that people must come to terms with their mortality and that, in so doing, people will be obligated to accept that they are free—that they possess free will and are at liberty to defy expectations and conventions in order to forge their own, meaningful paths through life. May believed that an important element of the meaning-making process is the search for myths, or narrative patterns into which the individual may fit.[16]
From the existential perspective, not only does the quest for meaning follow from an acceptance of mortality, but the attainment of meaning can overshadow the prospect of death. As Austrian existential psychiatrist and Holocaust survivor Viktor Frankl observed,[17] "We who lived in concentration camps can remember the men who walked through the huts comforting others, giving away their last piece of bread. They may have been few in number, but they offer sufficient proof that everything can be taken from a man but one thing: the last of the human freedoms—to choose one's attitude in any given set of circumstances, to choose one's own way".[18]
May helped to pioneer the development of existential therapy, and Frankl created a variety of it called logotherapy. In addition to May and Frankl, Swiss psychoanalyst Ludwig Binswanger and American psychologist George Kelly may be said to belong to the existential school.[19] Both existential and humanistic psychologists argue that people should strive to reach their full potential, but only humanistic psychologists believe that this striving is innate. For existential psychologists, the striving only follows an anxiety-producing contemplation of mortality, freedom, and responsibility.[20]
Cognitivism
Behaviorism was the dominant paradigm in American psychology throughout the first half of the 20th century. However, the modern field of psychology largely came to be dominated by cognitive psychology. Noam Chomsky's 1959 review of B. F. Skinner's Verbal Behavior challenged the behaviorist approaches to studies of behavior and language dominant at the time and contributed to the cognitive revolution in psychology. Chomsky was highly critical of what he considered arbitrary notions of 'stimulus', 'response' and 'reinforcement' which Skinner borrowed from animal experiments in the laboratory. Chomsky argued that Skinner's notions could only be applied to complex human behavior, such as language acquisition, in a vague and superficial manner. Chomsky emphasized that research and analysis must not ignore the contribution of the child in the acquisition of language and proposed that humans are born with a natural ability to acquire language.[21] Work most associated with psychologist Albert Bandura, who initiated and studied social learning theory, showed that children could learn aggression from a role model through observational learning, without any change in overt behavior, and so must be accounted for by internal processes.[22]
With the rise of computer science and artificial intelligence, analogies were drawn between information processing by humans and information processing by machines. This, combined with the assumptions that mental representations exist and that mental states and operations could be inferred through scientific experimentation in the laboratory, led to the rise of cognitivism as a popular model of the mind. Research in cognition was also backed by the aim to gain a better understanding of weapons operation since World War II.[23]
Cognitive psychology differs from other psychological perspectives in two key ways. First, it accepts the use of the scientific method, and generally rejects introspection as a method of investigation, unlike symbol-driven approaches such as Freudian psychodynamics. Second, it explicitly acknowledges the existence of internal mental states—such as belief, desire and motivation—whereas behaviorism does not. However, like Freud and depth psychologists, cognitive psychologists are interested in unconscious processes, including repression, but prefer to explore them in terms of operationally-defined components, such as subliminal processing and implicit memory, that are amenable to experimental investigation. Yet cognitive psychologists have questioned the very existence of some of these components. For example, American psychologist Elizabeth Loftus has used empirical methods to demonstrate ways in which apparent memories can be brought to light via fabrication rather than through the elimination of repression.
Preceding the cognitive revolution by several decades, Hermann Ebbinghaus had pioneered the experimental study of memory, arguing that higher mental processes are not hidden from view, but instead could be studied using experimentation.[24] Links between psychological activity and brain and nervous system function also became understood, partly due to the experimental work of people such as English neuroscientist Charles Sherrington and Canadian psychologist Donald Hebb, and partly due to studies of people with brain injury. These mind-body links are explored at length by cognitive neuropsychologists. With the development of technologies for measuring brain function, neuropsychology and cognitive neuroscience have become increasingly active areas of contemporary psychology. Cognitive psychology has been subsumed along with other disciplines, such as philosophy of mind, computer science, and neuroscience, under the umbrella discipline of cognitive science.
Schools of thought
Various schools of thought have argued for a particular model to be used as a guiding theory by which all, or the majority, of human behavior can be explained. The popularity of these has waxed and waned over time. Some psychologists may think of themselves as adherents to a particular school of thought and reject the others, although most consider each as an approach to understanding the mind, and not necessarily as mutually exclusive theories. On the basis of Tinbergen's four questions a framework of reference of all fields of psychological research can be established (including anthropological research and humanities).
In modern times, psychology has adopted an integrated perspective towards understanding consciousness, behavior, and social interaction. This perspective is commonly referred to as the biopsychosocial approach. The basic tenet of the biopsychosocial model is that any given behavior or mental process affects and is affected by dynamically interrelated biological, psychological, and social factors. [25] The psychological aspect refers to the role that cognition and emotions play in any given psychological phenomenon—for example, the effect of mood or beliefs and expectations on an individual's reactions to an event. The biological aspect refers to the role of biological factors in psychological phenomena—for example, the effect of the prenatal environment on brain development and cognitive abilities, or the influence of genes on individual dispositions. The socio-cultural aspect refers to the role that social and cultural environments play in a given psychological phenomenon—for example, the role of parental or peer influence in the behaviors or characteristics of an individual.
Subfields
Psychology encompasses a vast domain, and includes many different approaches to the study of mental processes and behavior. Below are the major areas of inquiry that comprise psychology. A comprehensive list of the sub-fields and areas within psychology can be found at the list of psychology topics and list of psychology disciplines.
Abnormal psychology
Abnormal psychology is the study of abnormal behavior in order to describe, predict, explain, and change abnormal patterns of functioning. Abnormal psychology studies the nature of psychopathology and its causes, and this knowledge is applied in clinical psychology to treat patients with psychological disorders.
It can be difficult to draw the line between normal and abnormal behaviors. In general, abnormal behaviors must be maladaptive and cause an individual significant discomfort in order to be of clinical and research interest. According to the DSM-IV-TR, behaviors may be considered abnormal if they are associated with disability, personal distress, the violation of social norms, or dysfunction.[26]
Biological psychology
![](http://upload.wikimedia.org/wikipedia/commons/thumb/b/b6/Hypothalamus.jpg/150px-Hypothalamus.jpg)
Biological psychology is the scientific study of the biological substrates of behavior and mental states. Seeing all behavior as intertwined with the nervous system, biological psychologists feel it is sensible to study how the brain functions in order to understand behavior. This is the approach taken in behavioral neuroscience, cognitive neuroscience, and neuropsychology. Neuropsychology is the branch of psychology that aims to understand how the structure and function of the brain relate to specific behavioral and psychological processes. Neuropsychology is particularly concerned with the understanding of brain injury in an attempt to work out normal psychological function. The approach of cognitive neuroscience to studying the link between brain and behavior is to use neuroimaging tools, such as to observe which areas of the brain are active during a particular task.
Cognitive psychology
Cognitive psychology studies cognition, the mental processes underlying behavior. It uses information processing as a framework for understanding the mind. Perception, learning, problem solving, memory, attention, language and emotion are all well researched areas. Cognitive psychology is associated with a school of thought known as cognitivism, whose adherents argue for an information processing model of mental function, informed by positivism and experimental psychology.
On a broader level, Cognitive science is a conjoined enterprise of cognitive psychologists, neurobiologists, researchers in artificial intelligence, logicians, linguists, and social scientists, and places a slightly greater emphasis on computational theory and formalization. Both areas can use computational models to simulate phenomena of interest. Because mental events cannot directly be observed, computational models provide a tool for studying the functional organization of the mind. Such models give cognitive psychologists a way to study the "software" of mental processes independent of the "hardware" it runs on, be it the brain or a computer.
Comparative psychology
Comparative psychology refers to the study of the behavior and mental life of animals other than human beings. It is related to disciplines outside of psychology that study animal behavior, such as ethology. Although the field of psychology is primarily concerned with humans, the behavior and mental processes of animals is also an important part of psychological research, either as a subject in its own right (e.g., animal cognition and ethology), or with strong emphasis about evolutionary links, and somewhat more controversially, as a way of gaining an insight into human psychology by means of comparison or via animal models of emotional and behavior systems as seen in neuroscience of psychology (e.g., affective neuroscience and social neuroscience).
Counseling psychology
Counseling psychology seeks to facilitate personal and interpersonal functioning across the lifespan with a focus on emotional, social, vocational, educational, health-related, developmental, and organizational concerns. Counselors are primarily clinicians, using psychotherapy and other interventions in order to treat clients. Traditionally, counseling psychology has focused more on normal developmental issues and everyday stress rather than psychopathology, but this distinction has softened over time. Counseling psychologists are employed in a variety of settings, including universities, hospitals, schools, governmental organizations, businesses, private practice, and community mental health centers.
Clinical psychology
Clinical psychology includes the study and application of psychology for the purpose of understanding, preventing, and relieving psychologically-based distress or dysfunction and to promote subjective well-being and personal development. Central to its practice are psychological assessment and psychotherapy, although clinical psychologists may also engage in research, teaching, consultation, forensic testimony, and program development and admharry potter.. ISBN 0174900589></ref> Some clinical psychologists may focus on the clinical management of patients with brain injury—this area is known as clinical neuropsychology. In many countries clinical psychology is a regulated mental health profession.
The work performed by clinical psychologists tends to be done inside various therapy models, all of which involve a formal relationship between professional and client—usually an individual, couple, family, or small group—that employs a set of procedures intended to form a therapeutic alliance, explore the nature of psychological problems, and encourage new ways of thinking, feeling, or behaving. The four major perspectives are Psychodynamic, Cognitive Behavioral, Existential-Humanistic, and Systems or Family therapy. There has been a growing movement to integrate these various therapeutic approaches, especially with an increased understanding of issues regarding culture, gender, spirituality, and sexual-orientation. With the advent of more robust research findings regarding psychotherapy, there is growing evidence that most of the major therapies are about of equal effectiveness, with the key common element being a strong therapeutic alliance.[27][28] Because of this, more training programs and psychologists are now adopting an eclectic therapeutic orientation.
Critical psychology
Critical psychology applies the methodology of critical theory to psychology. As such, it critiques not only the psychic substrates of the status quo, but also the elements of mainstream psychology that are, themselves, seen as contributors to oppressive ideologies.[29] Critical psychology operates on the belief "that mainstream psychology has institutionalized a narrow view of the field’s ethical mandate to promote human welfare"[30] by promoting individual remedies to social ills, encouraging trivial and inconsequential research, and engaging in other practices that its positivistic methods fail to place under critical scrutiny.
A critical psychologist might ask whether a case of "work stress" warrants efforts to change the macro-level systems that control the work,[31] rather than merely to treat the individual who experiences the stress—or, more accurately, who shares the stress with countless other individuals. One might also ask why "mainstream trauma efforts fail to incorporate a focus on human rights and social justice"[32] in war-ravaged communities. In short, critical psychology seeks, where it deems appropriate, to raise psychology's level of analysis from the individual to society,[33] and to render psychology more transformative than ameliorative.[34] Critical psychology has been applied to a wide array of psychology's other subfields, and many of its theorists are employed in mainstream psychological professions.
Developmental psychology
Mainly focusing on the development of the human mind through the life span, developmental psychology seeks to understand how people come to perceive, understand, and act within the world and how these processes change as they age. This may focus on intellectual, cognitive, neural, social, or moral development. Researchers who study children use a number of unique research methods to make observations in natural settings or to engage them in experimental tasks. Such tasks often resemble specially designed games and activities that are both enjoyable for the child and scientifically useful, and researchers have even devised clever methods to study the mental processes of small infants. In addition to studying children, developmental psychologists also study aging and processes throughout the life span, especially at other times of rapid change (such as adolescence and old age). Developmental psychologists draw on the full range of theorists in scientific psychology to inform their research.
Educational psychology
Educational psychology is the study of how humans learn in educational settings, the effectiveness of educational interventions, the psychology of teaching, and the social psychology of schools as organizations. The work of child psychologists such as Lev Vygotsky, Jean Piaget and Jerome Bruner has been influential in creating teaching methods and educational practices.
Evolutionary psychology
Evolutionary psychology explores the genetic roots of mental and behavioral patterns, and posits that common patterns may have emerged because they were highly adaptive for humans in the environments of their evolutionary past—even if some of these patterns are maladaptive in today's environments. Fields closely related to evolutionary psychology are animal behavioral ecology, human behavioral ecology, dual inheritance theory, and sociobiology. Memetics, founded by British evolutionary biologist Richard Dawkins, is a related but competing field[35] that proposes that cultural evolution can occur in a Darwinian sense but independently of Mendelian mechanisms; it therefore examines the ways in which thoughts, or memes, may evolve independently of genes.
Forensic psychology
Forensic psychology covers a broad range of practices including the clinical evaluations of defendants, reports to judges and attorneys, and courtroom testimony on given issues. Forensic psychologists are appointed by the court or hired by attorneys to conduct competency to stand trial evaluations, competency to be executed evaluations, sanity evaluations, involuntary commitment evaluations, provide sentencing recommendations, and sex offender evaluation and treatment evaluations and provide recommendations to the court through written reports and testimony. Many of the questions the court asks the forensic psychologist go ultimately to legal issues, although a psychologist cannot answer legal questions. For example, there is no definition of sanity in psychology. Rather, sanity is a legal definition that varies from place to place throughout the world. Therefore, a prime qualification of a forensic psychologist is an intimate understanding of the law, especially criminal law.
Health psychology
Health psychology is the application of psychological theory and research to health, illness and health care. Whereas clinical psychology focuses on mental health and neurological illness, health psychology is concerned with the psychology of a much wider range of health-related behavior including healthy eating, the doctor-patient relationship, a patient's understanding of health information, and beliefs about illness. Health psychologists may be involved in public health campaigns, examining the impact of illness or health policy on quality of life and in research into the psychological impact of health and social care.
Industrial/organizational psychology
Industrial and organizational psychology (I/O) applies psychological concepts and methods to optimize human potential in the workplace. Personnel psychology, a subfield of I/O psychology, applies the methods and principles of psychology in selecting and evaluating workers. I/O psychology's other subfield, organizational psychology, examines the effects of work environments and management styles on worker motivation, job satisfaction, and productivity. [36]
Legal psychology
Legal psychology is a research-oriented field populated with researchers from several different areas within psychology (although social and cognitive psychologists are typical). Legal psychologists explore such topics as jury decision-making, eyewitness memory, scientific evidence, and legal policy. The term "legal psychology" has only recently come into use, and typically refers to any non-clinical law-related research.
Personality psychology
Personality psychology studies enduring patterns of behavior, thought, and emotion in individuals, commonly referred to as personality. Theories of personality vary across different psychological schools and orientations. They carry different assumptions about such issues as the role of the unconscious and the importance of childhood experience. According to Freud, personality is based on the dynamic interactions of the ego, superego, and id.[37] Trait theorists, in contrast, attempt to analyze personality in terms of a discrete number of key traits by the statistical method of factor analysis. The number of proposed traits has varied widely. An early model proposed by Hans Eysenck suggested that there are three traits that comprise human personality: extraversion-introversion, neuroticism, and psychoticism. Raymond Cattell proposed a theory of 16 personality factors. The "Big Five" or Five Factor Model, proposed by Lewis Goldberg currently has strong support among trait theorists.
Quantitative psychology
Quantitative psychology involves the application of mathematical and statistical modeling in psychological research, and the development of statistical methods for analyzing and explaining behavioral data. The term Quantitative psychology is relatively new and little used (only recently have Ph.D. programs in quantitative psychology been formed), and it loosely covers the longer standing subfields psychometrics and mathematical psychology.
Psychometrics is the field of psychology concerned with the theory and technique of psychological measurement, which includes the measurement of knowledge, abilities, attitudes, and personality traits. Measurement of these unobservable phenomena is difficult, and much of the research and accumulated knowledge in this discipline has been developed in an attempt to properly define and quantify such phenomena. Psychometric research typically involves two major research tasks, namely: (i) the construction of instruments and procedures for measurement; and (ii) the development and refinement of theoretical approaches to measurement.
Whereas psychometrics is mainly concerned with individual differences and population structure, mathematical psychology is concerned with modeling of mental and motor processes of the average individual. Psychometrics is more associated with educational psychology, personality, and clinical psychology. Mathematical psychology is more closely related to psychonomics/experimental and cognitive, and physiological psychology and (cognitive) neuroscience.
Social psychology
![](http://upload.wikimedia.org/wikipedia/commons/thumb/0/0f/Shibuya_tokyo.jpg/150px-Shibuya_tokyo.jpg)
Social psychology is the study of social behavior and mental processes, with an emphasis on how humans think about each other and how they relate to each other. Social psychologists are especially interested in how people react to social situations. They study such topics as the influence of others on an individual's behavior (e.g. conformity, persuasion), and the formation of beliefs, attitudes, and stereotypes about other people. Social cognition fuses elements of social and cognitive psychology in order to understand how people process, remember, and distort social information. The study of group dynamics reveals information about the nature and potential optimization of leadership, communication, and other phenomena that emerge at least at the microsocial level. In recent years, many social psychologists have become increasingly interested in implicit measures, mediational models, and the interaction of both person and social variables in accounting for behavior.
School psychology
School psychology combines principles from educational psychology and clinical psychology to understand and treat students with learning disabilities; to foster the intellectual growth of "gifted" students; to facilitate pro social behaviors in adolescents; and otherwise to promote safe, supportive, and effective learning environments. School psychologists are trained in educational and behavioral assessment, intervention, prevention, and consultation, and many have extensive training in research.[38] Currently, school psychology is the only field in which a professional can be called a "psychologist" without a doctoral degree, with the National Association of School Psychologists (NASP) recognizing the Specialist degree as the entry level. This is a matter of controversy as the APA does not recognize anything below a doctorate as the entry level for a psychologist. Specialist-level school psychologists, who typically receive three years of graduate training, function almost exclusively within school systems, while those at the doctoral-level are found in a number of other settings as well, including universities, hospitals, clinics, and private practice.
Research methods
![](http://upload.wikimedia.org/wikipedia/commons/thumb/a/a3/Wundt-research-group.jpg/250px-Wundt-research-group.jpg)
Research in most areas of psychology is conducted in broad accord with the standards of the scientific method, encompassing both qualitative ethological and quantitative statistical modalities to generate and evaluate explanatory hypotheses with regard to psychological phenomena. Investigation may be pursued by experimental protocols, but alternative methods are sometimes preferred due to research ethics, the state of development in a given research domain, and other reasons.[39]
Psychology tends to be eclectic, drawing on knowledge from other fields to help explain and understand psychological phenomena. For example, evolutionary psychologists may synthesize data from multiple subfields of psychology, biology, and anthropology. Additionally, they make extensive use of two distinctive types of reasoning. While often employing the deductive-nomological reasoning of strict positivism, they also rely on inductive reasoning to generate accounts of hunter-gatherer life that could explain the adaptive value of different thoughts and actions.
Qualitative psychological research utilizes a broad spectrum of observational methods, including action research, ethnography, exploratory statistics, structured interviews, and participant observation, to enable the gathering of rich information unattainable by classical experimentation. Research in humanistic psychology is more typically pursued via ethnographic, historical, and historiographic methods than via science. Psychodynamic research has traditionally entailed interpreting clinical case studies, and subschools ranging from Freudian psychoanalysis to Neo-Jungian archetypal psychology have employed myth as a vehicle of interpretation. Recent developments, particularly in neuro-psychoanalysis, have demanded a relatively high degree of scientific rigor.
A precursor to critical psychology, liberation psychology, cited traditional surveys in its emancipatory quests.[34] There is debate amongst critical psychologists as to whether they should be the ones to apply the research they conduct—as to how action-oriented or awareness-oriented they should be.[40] In general, though, their methods tend to be critical rather than positivistic, and therefore tend not only to avoid the scientific method, but also to identify the ways in which this method is improperly used and downright abused.[29] A key concept in critical-psychological research is reflexivity, or critical self-examination that entails "a conscious exploration of how [psychologists'] own values and assumptions affect [their] theoretical and methodological goals, activities, and interpretations".[41] Taking a reflexive approach, critical psychologists both scrutinize the current state of psychological affairs, and seek defensible positions on the "old questions—such as free will vs. determinism, nature vs. nurture, [and] consciousness vs. unconscious forces".[42]
The testing of different aspects of psychological function is a significant area of mainstream psychology. Psychometric and statistical methods predominate, including various well-known standardized tests as well as those created ad hoc as the situation or experiment requires.
Academic psychologists may focus purely on research and psychological theory, aiming to further psychological understanding in a particular area, while other psychologists may work in applied psychology to deploy such knowledge for immediate and practical benefit. These approaches are not mutually exclusive, and many psychologists will be involved in both researching and applying psychology at some point during their career. Many clinical psychology programs aim to develop in practicing psychologists both knowledge of and experience with research and experimental methods, which they may interpret and employ as they treat individuals with psychological issues.
When an area of interest requires specific training and specialist knowledge, especially in applied areas, psychological associations normally establish a governing body to manage training requirements. Similarly, requirements may be laid down for university degrees in psychology, so that students acquire an adequate knowledge in a number of areas. Additionally, areas of practical psychology, where psychologists offer treatment to others, may require that psychologists be licensed by government regulatory bodies as well.
Controlled experiments
Experimental psychological research is conducted in a laboratory under controlled conditions. This method of research relies on the application of the scientific method to understand behavior. Experimenters use several types of measurements, including rate of response, reaction time, and various psychometric measurements. Experiments are designed to test specific hypotheses (deductive approach) or evaluate functional relationships (inductive approach). They allow researchers to establish causal relationships between different aspects of behavior and the environment. In an experiment, one or more variables of interest are controlled by the experimenter (independent variable) and another variable is measured in response to different conditions (dependent variable). Experiments are one of the primary research methods in many areas of psychology, particularly cognitive/psychonomics, mathematical psychology, psychophysiology and biological psychology/cognitive neuroscience.
Experiments on humans have been put under some controls, namely informed and voluntary consent. After World War II, the Nuremberg Code was established, because of Nazi abuses of experimental subjects. Later, most countries (and scientific journals) adopted the Declaration of Helsinki. In the US, the National Institutes of Health established the Institutional Review Board in 1966, and in 1974 adopted the National Research Act (HR 7724). All of these measures encouraged researchers to obtain informed consent from human participants in experimental studies. A number of influential studies led to the establishment of this rule; such studies included the MIT and Fernald School radioisotope studies, the Thalidomide tragedy, the Willowbrook hepatitis study, and Stanley Milgram's studies of obedience to authority.
Survey questionnaires
Statistical surveys are used in psychology for measuring attitudes and traits, monitoring changes in mood, checking the validity of experimental manipulations, and for a wide variety of other psychological topics. Most commonly, psychologists use paper-and-pencil surveys. However, surveys are also conducted over the phone or through e-mail. Increasingly, web-based surveys are being used in research.[43] Similar methodology is also used in applied setting, such as clinical assessment and personnel assessment.
Longitudinal studies
A longitudinal study is a research method which observes a particular population over time. For example, one might wish to study specific language impairment (SLI) by observing a group of individuals with the condition over a period of time. This method has the advantage of seeing how a condition can affect individuals over long time scales. However, such studies can suffer from attrition due to drop-out or death of subjects. In addition, since individual differences between members of the group are not controlled, it may be difficult to draw conclusions about the populations. Longitudinal study is a developmental research strategy that involves testing an age group repeatedly over many years. Longitudinal studies answer vital questions about how people develop. This developmental research follows people over years and the outcome has been an incredible array of findings, especially relating to psychological problems.
Observation in natural settings
In the same way Jane Goodall studied the role of chimpanzee social and family life, psychologists conduct similar observational studies in human social, professional and family lives. Sometimes the participants are aware they are being observed and other times it is covert: the participants do not know they are being observed. Ethical guidelines need to be taken into consideration when covert observation is being carried out.
Qualitative and descriptive research
Research designed to answer questions about the current state of affairs such as the thoughts, feelings and behaviors of individuals is known as descriptive research. Descriptive research can be qualitative or quantitative in orientation. Qualitative research is descriptive research that is focused on observing and describing events as they occur, with the goal of capturing all of the richness of everyday behavior and with the hope of discovering and understanding phenomena that might have been missed if only more cursory examinations have been made.
Neuropsychological methods
Neuropsychology involves the study of both healthy individuals and patients, typically who have suffered either brain injury or mental illness.
Cognitive neuropsychology and cognitive neuropsychiatry study neurological or mental impairment in an attempt to infer theories of normal mind and brain function. This typically involves looking for differences in patterns of remaining ability (known as 'functional disassociations') which can give clues as to whether abilities are comprised of smaller functions, or are controlled by a single cognitive mechanism.
In addition, experimental techniques are often used to study the neuropsychology of healthy individuals. These include behavioral experiments, brain-scanning or functional neuroimaging, used to examine the activity of the brain during task performance, and techniques such as transcranial magnetic stimulation, which can safely alter the function of small brain areas to reveal their importance in mental operations.
Computational modeling
![](http://upload.wikimedia.org/wikipedia/commons/thumb/4/47/MultiLayerNeuralNetwork_english.png/150px-MultiLayerNeuralNetwork_english.png)
Computational modeling[44] is a tool often used in mathematical psychology and cognitive psychology to simulate a particular behavior using a computer. This method has several advantages. Since modern computers process extremely quickly, many simulations can be run in a short time, allowing for a great deal of statistical power. Modeling also allows psychologists to visualize hypotheses about the functional organization of mental events that couldn't be directly observed in a human.
Several different types of modeling are used to study behavior. Connectionism uses neural networks to simulate the brain. Another method is symbolic modeling, which represents many different mental objects using variables and rules. Other types of modeling include dynamic systems and stochastic modeling.
Animal studies
![](http://upload.wikimedia.org/wikipedia/commons/thumb/e/ec/One_of_Pavlov%27s_dogs.jpg/220px-One_of_Pavlov%27s_dogs.jpg)
Animal learning experiments are important in many aspects of psychology such as investigating the biological basis of learning, memory and behavior. In the 1890s, physiologist Ivan Pavlov famously used dogs to demonstrate classical conditioning. Non-human primates, cats, dogs, rats and other rodents are often used in psychological experiments. Controlled experiments involve introducing only one variable at a time, which is why animals used for experiments are housed in laboratory settings. In contrast, human environments and genetic backgrounds vary widely, which makes it difficult to control important variables for human subjects.[45]
Criticism and controversies
Status as a science
A common criticism of psychology concerns its fuzziness as a science. Philosopher Thomas Kuhn's 1962 critique implied psychology overall was in a pre-paradigm state, lacking the agreement on overarching theory found in mature sciences such as chemistry and physics. Psychologists and philosophers have addressed the issue in various ways.[46]
Because some areas of psychology rely on research methods such as surveys and questionnaires, critics have asserted that psychology is not scientific. Other phenomena that psychologists are interested in such as personality, thinking, and emotion cannot be directly measured and are often inferred from subjective self-reports, which may be problematic.
The validity of probability testing as a research tool has been called into question. There is concern that this statistical method may promote trivial findings as meaningful, especially when large samples are used.[47] Some psychologists have responded with an increased use of effect size statistics, rather than sole reliance on the traditional p<.05 decision rule in statistical hypothesis testing.
Sometimes the debate comes from within psychology, for example between laboratory-oriented researchers and practitioners such as clinicians. In recent years, and particularly in the U.S., there has been increasing debate about the nature of therapeutic effectiveness and about the relevance of empirically examining psychotherapeutic strategies.[48] One argument states that some therapies are based on discredited theories and are unsupported by empirical evidence. The other side points to recent research suggesting that all mainstream therapies are of about equal effectiveness, while also arguing that controlled studies often do not take into consideration real-world conditions.[49]
Fringe clinical practices
There is also concern about a perceived gap between scientific theory and its application, in particular with the application of unproven or unsound clinical practices. Researchers such as Beyerstein (2001) say there has been a large increase in the number of mental health training programs that do not emphasize science training.[50] According to Lilienfeld (2002) "a wide variety of unvalidated and sometimes harmful psychotherapeutic methods, including facilitated communication for infantile autism... suggestive techniques for memory recovery (e.g., hypnotic age-regression, guided imagery, body work), energy therapies (e.g., Thought Field Therapy, Emotional Freedom Technique)... and New Age therapies of seemingly endless stripes (e.g., rebirthing, reparenting, past-life regression, Primal...therapy, neurolinguistic programming, alien abduction therapy, angel therapy) have either emerged or maintained their popularity in recent decades."[51] Allen Neuringer made a similar point in the field of the experimental analysis of behavior in 1984.[52]
