Abstract

Categorization represents the over-simplification of a near-infinite amount of information, so rather than become overwhelmed, people can rationally make sense of their experiences. However, doing so can also result in poor decisions when the “sense-making” is over-generalized, based on stereotypes, or biased towards the potential of negative consequences. Surprisingly, recent research reveals whether the categorization is expressed explicitly or implicitly can influence the subsequent decision and has been examined the categorization-decision paradigm. Temporally precise event-related potential (ERP) waveforms from scalp electroencephography (EEG) are well-suited to map neural activity onto sequential social cognitions processes like the categorization-decision paradigm. In particular, studying both P3 and CNV components can provide important insights about the way multiple components differentially process explicit versus implicit categorization and their effects on subsequent decisions. In addition, the temporal precision of neural correlates can help distinguish between implicit automatic stereotyping versus potentially more resource intensive constructive processes.
