Eleanor Rosch (once known as Eleanor Rosch Heider) was born in 1938, she now lives and works as a professor of psychology in the United states of America. She is most well known for her work on categorization as well as the formation of the Prototype theory within the field of cognitive psychology. Her research has been influential in many fields. Rosch has conducted extensive research focusing on topics that include semantic categorization, mental representation of concepts, linguistics and prototype theory. [1]
Rosch's research interests include cognition, concepts, causality, thinking, memory, and cross-cultural, Eastern, and religious psychology. Most recently her focus on psychology of religion has shown the implications of Buddhism.
Biography
Career and education
Eleanor Rosch is a professor of psychology at the University of California, Berkely, in the department of Psychology and the program in cognitive science. Rosch received her B.A. with a thesis in philosophy from Reed College and earned her Ph.D. at Harvard in 1969.
Her research in the 1970s demonstrated that when people label an everyday object the rely on a comparison with what they regard as the best representative of the category designated by that word. Through field work that Rosch conducted with the Dani Tribe of New Guinea she was able to show that although their language lacks words for colours other than black or white, they are still able to distinguish among other colours. She extended this finding to all cultures, arguing that people from different cultures tend to categorize in the same manner. This finding contradicted the Sapir-Whorf hypothesis, which claims that language effects the extent to which people can understand concepts for which their language does not have a words for.[2]
categorizaion
Research by Eleanor Rosch has focused a great deal on mental representations of natural categories. In her research a category is defined by a number of objects that are considered equivalent. Objects can be categorized in hierarchical levels, in either subordinate, basic or superordinate levels. Categorization is an unconscious processes that does not undergo any significant development during ones lifetime.[3] Rosch has proposed that categories are structured within taxonomies of concrete objects for which there is one level of inclusiveness; from here basic category cuts can be made.[4] Rosch along with other psychologists have argued that the basic level of categorization is that which the categories maximize within-category similarities relative to between-category similarities.5 Objects which are categorized in this basic level are more rapidly recognized than objects stored at any other level.[3] Cognitive representations of semantic categories is directly relevant to two areas of psychological inquiry. The first is focused on the structure of categories which has implications for the ways in which categorization should be studied. The second area is the nature of mental representations themselves.[5] Through further research Rosch has discovered that categorizations that are made about the concrete world are highly determined by psychological principles. [6] Rosch conducted studies to test her theories of natural categorization.she believed that semantic categories were developed around natural prototypes.[7]
Principles of categorization
Rosch attributed the formation to categories to two fundamental principles. The principle states that the task of a category is to provide maximum information while requiring the least amount of cognitive effort. This principle uses the logical notion that categories are useful for gaining a large amount of information while conserving resources and effort as much as possible. The second principle responsible for categorization is focused on the structure of information. It states that the perceived world contains structured information rather than arbitrary attributes. This principle suggests that objects within the concrete world are part of a highly correlated structure. [6]
family resemblances
An important area of focus of Rosch’s research is the idea of family resemblances of categories.[8] The concept of family resemblances counters the all-or-nothing phenomenon that was the original basis of categories. It instead supports the idea that category members vary in degrees of representativeness. Eleanor has stated that the structure of categories can be divided into prototype members, which serve as the best examples of the category, and nonprotoype members, which are the pooper examples of the category. Research has discovered that more prototypical items share a greater family resemblance to other members within the same category, and share little family resemblance to items in other categories.
Prototype theory
Rosch and her colleagues developed the prototype theory which further enhanced the theory of categorization. One explanation for prototypes are that they are the objects which have the mean values of quantifiable attributes of the category to which they belong .[2] However research conducted by Rosch has supported the hypothesis that a prototype is defined as the member of a category which has the most attributes in common with other members of the same category and the least attributes that same with members of another category. The concepts of prototypes have been used in social psychology, personality psychology and clinical psychology.[2]
Concepts
Another topic within psychology that Rosch devoted much of her research to was that of concepts. she described concepts as the mechanism that enables one to interpret situations in terms of similarities to previously encountered situations.[9] Concepts can be either concrete or abstract. A perspective about concepts that is becoming more generally recognized is that they have no fixed representational structure.[9] Rosch and her colleagues introduced the idea of a graded membership of concepts. Concepts may have a great deal of members, however it is likely that some members are more representative of the concept than others.
Publications
During her research Rosch has contributed numerous publications to the field of psychology. Her works range from full books to journal articles. a great deal of her work is focused on the concept of categorization or natural categories. She has also provided research on prototype theory as well as other topics.
When I am done improving and expanding this article about Eleanor Rosch it will include sections about natural categories as well as the prototype theory both of which Rosch was very influential in producing. The current article contains a section on publications by Rosch. When I am done editing the article this section will be placed at the bottom of the article, after categorization and prototype theory.
The first heading will be categorization. In this section I will provide an in depth focus on her lengthy works on categorization. Rosch focused a great deal on natural categories. In studies by Rosch and colleagues items which fall into presumed natural categories are easier to learn than items which fall into other domains. Another aspect of interest in Rosch’s studies which I will discuss in the article is the difference between natural and artificial categories. [10]
The second heading will be Prototype theory. In this section I will explain what prototype theory is and how Eleanor Rosch was involved in the creation of the theory. An important aspect that Eleanor Rosch focuses on when discussing prototype theory is family resemblances. Family resemblances are the based on the number of features that category members share.[11]
