Neural Correlates Of The Implicit Association Test: Evidence For Semantic And Emotional Processing, Jason R. Themanson, John K. Williams Aug 2011

Neural Correlates Of The Implicit Association Test: Evidence For Semantic And Emotional Processing, Jason R. Themanson, John K. Williams

Jason R. Themanson, Ph.D

The implicit association test (IAT) has been widely used in social cognitive research over the past decade. Controversies have arisen over what cognitive processes are being tapped into using this task. While most models use behavioral (RT) results to support their claims, little research has examined neurocognitive correlates of these behavioral measures. The present study measured event-related brain potentials (ERPs) of participants while completing a gay-straight IAT in order to further understand the processes involved in a typical group bias IAT. Results indicated significantly smaller N400 amplitudes and significantly larger LPP amplitudes for compatible trials than for incompatible trials, suggesting …

The Relation Of Self-Efficacy And Error-Related Self-Regulation, Jason Themanson, Matthew Pontifex, Charles Hillman, Edward Mcauley Mar 2011

The Relation Of Self-Efficacy And Error-Related Self-Regulation, Jason Themanson, Matthew Pontifex, Charles Hillman, Edward Mcauley

Jason R. Themanson, Ph.D

Relations between a modifiable psychosocial factor, self-efficacy (SE), and behavioral and neural indices of self-regulation, including post-error behavior, the error-related negativity (ERN), and error positivity (Pe) were examined in young adults during a flanker task emphasizing either accuracy or speed. SE was predicted to be associated with larger ERN and Pe amplitudes, as well as greater post-error behavioral performance during task conditions emphasizing accuracy, but not speed. Results showed that higher SE was associated with greater post-error response accuracy during the accuracy condition, but not the speed condition, and higher SE was related with greater ERN amplitudes across instruction conditions. …
