Title: Personally Familiar Face Processing - A Means to Study the Interaction Between Memory and Perception
Abstract: Humans are highly efficient at recognizing individuals encountered repeatedly in real life. Personally familiar faces can be readily identified when the available visual information is restricted or degraded (e.g. due to partial occlusion, or changes in viewing distance). In this talk I will present behavioral findings that demonstrate how facial representations stored in memory can facilitate perceptual processing. Compared to unfamiliar controls, subjects who were personally familiar with the faces presented exhibited more efficient integration of information retained across viewing distances and discrimination of facial identity. I will argue that these findings can be accounted for by an experience-dependent increase in the ability to rapidly extract facial information globally. These
findings will be complemented by the results of a recent neuroimaging study involving a novel dynamic coarse-to-fine visual stimulation paradigm. Mimicking the time course of face perception, we sought to characterize neural responses related to the process of familiar and unfamiliar face recognition (i.e. familiarity decisions). Our findings emphasize the importance of medial and anterior temporal regions for familiar face recognition. Specifically, they suggest that regions of the 'core' system accumulate perceptual evidence that is used for categorization of familiarity in areas of the 'extended' system, including both face-preferential and non-preferential structures.
