Wait, what? Assessing stereotype incongruities using the N400 ERP component.

Area of Science:

• Cognitive Psychology
• Social Psychology
• Neuroscience

Background:

• Cognitive psychology has advanced stereotype research.
• Psychophysiological techniques are increasingly applied to social cognition.

Purpose of the Study:

• To investigate gender stereotypes using psychophysiological measures.
• To examine cognitive processing of stereotype-congruent and incongruent information.

Main Methods:

• Participants categorized words as matching or not matching gender stereotypes after priming with 'Women' or 'Men'.
• Response times and event-related brain potentials (ERPs) were recorded.
• The N400 component of ERPs was analyzed.

Main Results:

• Stereotype-inconsistent words led to significantly slower response times compared to congruent words.
• Larger N400 amplitudes were observed for stereotype-inconsistent word pairs.
• These findings suggest measurable neural correlates of stereotype processing.

Conclusions:

• Psychophysiological methods, specifically ERPs, offer a valuable tool for studying stereotypes.
• The N400 component reflects the cognitive effort involved in processing stereotype-inconsistent information.
• This approach provides an objective measure of stereotype endorsement and processing.
