Abstract

Event-related brain potentials (ERPs) to colored slides contained a late positive component that was significantly enhanced when adults recognized the person, place, or painting in the photograph. Additionally, two late components change in amplitude, corresponding to the amount of surprise reported. Because subjects received no instructions to differentiate among the slides, these changes in brain potentials reflect natural classifications made according to their perceptions and evaluations of the pictorial material. This may be a useful paradigm with which to assess perception, memory, and orienting capacities in populations such as infants who cannot follow verbal instructions.
