==Neurobiology of Persuasion== |

Attitudes and persuasion are among the central issues of social behavior. One of the classic questions is when are attitudes a predictor of behavior. Previous research suggested that selective activation of left prefrontal cortex might increase the likelihood that an attitude would predict a relevant behavior. Using lateral attentional manipulation, this was supported. <ref> Drake, R. A., & Sobrero, A. P. (1987). Lateral orientation effects upon trait behavior and attitude behavior consistency. Journal of Social Psychology, 127, 639-651. </ref> |

An earlier article showed that EEG measures of anterior prefrontal asymmetry might be a predictor of persuasion. Research participants were presented with arguments that favored and arguments that opposed the attitudes they already held. Those whose brain was more active in left prefrontal areas said that they paid the most attention to statements with which they agreed while those with a more active right prefrontal area said that they paid attention to statements that disagreed. <ref> Cacioppo, J. T., Petty, R. E., & Quintanar, L. R. (1982). Individual differences in relative hemispheric alpha abundance and cognitive responses to persuasive communications. Journal of Personality and Social Psychology, 43, 623-636. </ref> This is an example of defensive repression, the avoidance or forgetting of unpleasant information. Research has shown that the trait of defensive repression is related to relative left prefrontal activation. <ref> Tomarken, A. J., & Davidson, R. J. (1994). Frontal brain activity in repressors and nonrepressors. Journal of Abnormal Psychology, 103, 339-349. </ref> In addition, when pleasant or unpleasant words, probably analogous to agreement or disagreement, were seen incidental to the main task, an fMRI scan showed preferential left prefrontal activation to the pleasant words <ref> Herrington, J. D., Mohanty, A., Koven, N. S., Fisher, J. E., Stewart, J. L., Banich, M. T., et al. (2005). Emotion-modulated performance and activity in left dorsolateral prefrontal cortex. Emotion, 5, 200-207. </ref> |

One way therefore to increase persuasion would seem to be to selectively activate the right prefrontal cortex. This is easily done by monaural stimulation to the contralateral ear. The effect apparently depends on selective attention rather than merely the source of stimulation. This manipulation had the expected outcome: more persuasion for messages coming from the left <ref> Drake, R. A., & Bingham, B. R. (1985). Induced lateral orientation and persuasibility.

Revision as of 22:22, 30 January 2010
Social neuroscience is an interdisciplinary field devoted to understanding how biological systems implement social processes and behavior, and to using biological concepts and methods to inform and refine theories of social processes and behavior.
Humans are fundamentally a social species, rather than individualists. As a social species, Homo sapiens create emergent organizations beyond the individual - structures that range from dyads, families, and groups to cities, civilizations, and cultures. These emergent structures evolved hand in hand with neural and hormonal mechanisms to support them because the consequent social behaviors helped these organisms survive, reproduce, and care for offspring sufficiently long that they too survived to reproduce.
The term "social neuroscience" can be traced to an article by John Cacioppo and Gary Berntson, published in the American Psychologist in 1992.[1] Cacioppo and Berntson are considered as the legitimate fathers of Social Neuroscience. Still a young field, social neuroscience is closely related to affective neuroscience and cognitive neuroscience, focusing on how the brain mediates social interactions.
Overview
Traditional neuroscience has for many years considered the nervous system as an isolated entity and largely ignored influences of the social environments in which humans and many animal species live. In fact, we now recognize the considerable impact of social structures on the operations of the brain and body. These social factors operate on the individual through a continuous interplay of neural, neuroendocrine, metabolic and immune factors on brain and body, in which the brain is the central regulatory organ and also a malleable target of these factors.[2] Social neuroscience investigates the biological mechanisms that underlie social processes and behavior, widely considered one of the major problem areas for the neurosciences in the 21st century, and applies concepts and methods of biology to develop theories of social processes and behavior in the social and behavioral sciences. Social neuroscience capitalizes on biological concepts and methods to inform and refine theories of social behavior, and it uses social and behavioral constructs and data to inform and refine theories of neural organization and function.[3]
Throughout most of the 20th century, social and biological explanations were widely viewed as incompatible. But advances in recent years have led to the development of a new approach synthesized from the social and biological sciences. The new field of social neuroscience emphasizes the complementary relationship between the different levels of organization spanning the social and biological domains (e.g., molecular, cellular, system, person, relational, collective, societal) and the use of multi-level analyses to foster understanding of the mechanisms underlying the human mind and behavior.
Methods
A variety of techniques are used in social neuroscience to investigate the confluence of neural and social processes, including Functional MRI, Transcranial magnetic stimulation, Event-related potentials, Electrocardiograms, Electromyograms, Galvanic skin response, and studies of Focal Brain Lesion patients. Animal models are also important to investigate the putative role of specific brain structures, circuits, or processes. In addition, quantitative meta-analyses are important to move beyond idiosyncrasies of individual studies, and neurodevelopmental investigations can contribute to our understanding of brain-behavior associations.[4]
Society for Social Neuroscience
A dinner to discuss the challenges and opportunities in the interdisciplinary field of social neuroscience at the Society for Neuroscience meeting (Chicago, November 2009) resulted to meetings led by John Cacioppo and Jean Decety with social neuroscientists, psychologists, neuroscientists, and neurologists in Argentina, Australia, Chile, China, Columbia, Hong Kong, Israel, Japan, Netherlands, New Zealand, Singapore, South Korea, Taiwan, United Kingdom, and United States. It was noted that, as a social species, humans create emergent organizations beyond the individual - structures that range from dyads, families, and groups to cities, civilizations, and international alliances. These emergent structures evolved hand in hand with neural, hormonal, cellular, and genetic mechanisms to support them because the consequent social behaviors helped humans survive, reproduce, and care for offspring sufficiently long that they too survived to reproduce, thereby ensuring their genetic legacy. Social neuroscience was defined broadly as the interdisciplinary study of the neural, hormonal, cellular, and genetic mechanisms underlying the emergent structures that define social species. Thus, among the participants in these meetings were scientists who used a wide variety of methods in studies of animals as well as humans and patients as well as normal participants. The consensus also emerged that a Society for Social Neuroscience should be established to give scientists from diverse disciplines and perspectives the opportunity to meet, communicate with, and benefit from the work of each other. The international, interdisciplinary Society for Social Neuroscience (http://S4SN.org) was launched at the conclusion of these consultations in Auckland, New Zealand on 20 January 2010, and the inaugural meeting for the Society was specified as the day prior to the 2010 Society for Neuroscience meeting (San Diego, CA).
