Novel Self-categorization Overrides Racial Bias: A Multi-level Approach to Intergroup Perception and EvaluationVan Bavel, Jay 26 February 2009 (has links)
People engage in a constant and reflexive process of categorizing others according to their race, gender, age or other salient social category. Decades of research have shown that social categorization often elicits stereotypes, prejudice, and discrimination. Social perception is complicated by the fact that people have multiple social identities and self-categorization with these identities can shift from one situation to another, coloring perceptions and evaluations of the self and others. This dissertation provides evidence that self-categorization with a novel group can override ostensible stable and pervasive racial biases in memory and evaluation and examines the neural substrates that mediate these processes. Experiment 1 shows that self-categorization with a novel mixed-race group elicited liking for ingroup members, regardless of race. This preference for ingroup members was mediated by the orbitofrontal cortex – a region of the brain linked to subjective valuation. Participants in novel groups also had greater fusiform and amygdala activity to novel ingroup members, suggesting that these regions are sensitive to the current self-categorization rather than features associated with race. Experiment 2 shows that preferences for ingroup members are evoked rapidly and spontaneously, regardless of race, indicating that ingroup bias can override automatic racial bias. Experiment 3 provides evidence that preferences for ingroup members are driven by ingroup bias rather than outgroup derogation. Experiment 4 shows that self-categorization increases memory for ingroup members eliminating the own-race memory bias. Experiment 5 provides direct evidence that fusiform activity to ingroup members is associated with superior memory for ingroup members. This study also shows greater amygdala activity to Black than White faces who are unaffiliated with either the ingroup or outgroup, suggesting that social categorization is flexible, shifting from group membership to race within a given social context. These five experiments illustrate that social perception and evaluation are sensitive to the current self-categorization – however minimal – and characterized by ingroup bias. This research also offers a relatively simple approach for erasing several pervasive racial biases. This multi-level approach extends several theories of intergroup perception and evaluation by making explicit links between self-categorization, neural processes, and social perception and evaluation.

An investigation into whether learning about social cognitive neuroscience in a leader development intervention helps to facilitate behavioural change in leadersCoetzer, Estelle Lydia 01 1900 (has links)
Text in English / The field of neuroscience is increasingly gaining exposure in the leadership domain, where it is now beginning to contribute to research and development. In this study an exploratory investigation of leadership development was undertaken with four primary aims. Firstly, to find out whether exposing participants in managerial positions to cognitive neuroscience knowledge contributes to their development as leaders. Secondly, to explore and illuminate the underlying processes that support such behavioural change. Thirdly, to investigate how behaviour changes in leaders exposed to social cognitive neuroscience knowledge are manifested within an organisational setting. Fourthly, to determine what the perceived impact on the leaders and others are regarding such behaviour changes in a specific organisational context, namely a retail environment.
In the study, leaders were exposed to a social cognitive neuroscience workshop over a 5-month period. They were provided with foundational knowledge of social cognitive neuroscience in workshops with two objectives. Firstly, the workshops were intended to enhance their understanding of the brain and cognitive systems underlying thinking and behaviour of the self and others. Secondly, in the workshops the complex interaction between brain systems and subsystems such as the executive and emotional systems were shown to mirror, in a metaphorical way, some of the complex interactions between structures in business organisations. Semi-structured interviews were conducted with a purposive sample of 16 participants, as well as with some their line managers and direct reports. Data were qualitatively analysed by means of content analysis.
Findings support the view that gaining social cognitive neuroscience knowledge led to increased self-awareness and an understanding of others. Implicit behavioural change resulted from cognitive and affective changes. Explicit behaviour changes were the result of conscious choice and were supported by both personal and organisational motivational drives. Leaders made behaviour changes at both personal and interactive levels based on their understanding of social cognitive neuroscience. Behaviour changes related to increased emotional regulation, a change in leadership style, an inclusive communication style, cultivating relationships, recognition strategies and strengthening trust. The implemented behaviour changes had a positive impact on participants and their direct reports and related mostly to positive affective changes, growth and development, improved relationships, personal effectiveness and team dynamics. / Psychology / D.
