“…For instance, Corneille, Huart, Becquart, and Brédart (2004) showed that faces whose race is made ambiguous through morphing with a face from another race are misremembered as being closer to their own-race prototype than they actually are. The same effect applies to faces that are made ambiguous as to gender identity, with memory distortions toward gender prototypes (Huart, Corneille, & Becquart, 2005).…”

Previous research on faces has shown a relation between facial attractiveness and the mathematical averageness of a face (e.g., Langlois & Roggman, 1990). Rhodes, Harwood, Yoshikawa, Nishitani, and McLean (2002) also showed that people from different social groups (e.g., Caucasian and Asian) show high intergroup correlations in attractiveness ratings of the same mathematically average faces, regardless of the group memberships of the raters or of the faces being rated. Yet, relatively little is known about how people's mental representations of faces relate to the faces' attractiveness. In particular, no research to date has examined how faces that vary in attractiveness are represented relative to mathematical averages (i.e., to prototypes) for various ethnic groups, a gap that the present research was designed to address.One popular framework used to understand how faces are perceived, encoded, and retrieved is the face space (Lewis, 2004;Valentine, 1991). This space is akin to a mental "map" in which each dimension is normally distributed and holds information necessary to remembering and recognizing a face. Busey (1998) showed that the face space can be modeled adequately using multidimensional scaling (MDS) analysis. He used faces of bald men and their morphs in a similarity judgment task involving all possible combinations of faces. The morphs appeared more typical than their parent faces and were found closer to the center, in line with predictions made by the face space model. The morphs were also found to be less typical than predicted, consistent with recent research on attractor field models that has shown

Motor‐evoked potentials reveal a motor‐cortical readout of evidence accumulation for sensorimotor decisions

This is the accepted version of the paper.This version of the publication may differ from the final published version. Permanent repository link AbstractMany everyday activities require time-pressured sensorimotor decision making.Traditionally, perception, decision and action processes were considered to occur in series, but this idea has been successfully challenged, particularly by neurophysiological work in animals. However, the generality of parallel processing requires further elucidation. Here, we investigate whether the accumulation of a decision can be observed intrahemispherically within human motor cortex. Participants categorised faces as male or female, with task difficulty manipulated using morphed stimuli. Transcranial magnetic stimulation, applied during the reaction-time interval, produced motor-evoked potentials (MEPs) in two hand muscles that were the major contributors when generating the required pinch/grip movements. Smoothing MEPs using a Gaussian kernel allowed us to recover a continuous time-varying MEP average, comparable to an EEG component, permitting precise localisation of the time at which the motor plan for the responding muscle became dominant.We demonstrate decision-related activity in the motor cortex during this perceptual discrimination task, suggesting ongoing evidence accumulation within the motor system even for two independent actions represented within one hemisphere.

“…Corneille, Huart, Becquart, and Brédart (2004) find that a 70% White target (i.e., a morphed Asian-White target) is remembered as having more White-typical features than it actually had. After encoding a face, in a subsequent identity matching task, participants chose exemplars who were more White prototypic (e.g., the 80% or 90% White morph) than was the actual identity observed (see also Huart, Corneille, & Becquart, 2005). Insofar as activated social categories can bias both the perception of and memory for targets toward the category prototype, this could potentially degrade face recognition accuracy.…”
