Abstract

ABSTRACT: Evidence exists that people's brains respond differently to stimuli that violate social expectations. However, there are inconsistencies between studies in the event-related potentials (ERP) on which differential brain responses are found, as well as in the direction of the differences. Therefore, the current paper examined which of the two most frequently used tasks, the Impression Formation Task (IFT) or Implicit Association Test (IAT), provided more robust ERP components in response to the violation of gendered expectations. Both IFT and IAT paradigms were administered in a counter-balanced way among 25 young adults (age 22–31, 56% male), while brain activity was assessed with electroencephalography. The IFT and IAT specifically measured the violation of gendered expectations with regard to toy preferences and behavioral tendencies of young children. The results showed that both tasks were able to elicit relevant ERP components. Yet, the IFT evoked ERP effects of the violation of gendered expectations on all but one of the selected ERP components; the P1, N1, and LPP. The IAT only elicited different P3 amplitudes when expectations were violated. We recommend the use of IFT paradigms when studying neural processes underlying the violation of social expectations.
