Vision provides us with an ever-changing neural representation of the world from which we
must extract stable object categorizations. We argue that visual analysis involves a …

Seeking to understand how people recognize objects, we have examined how they identify
letters. We expected this 26-way classification of familiar forms to challenge the popular …

Faces are perceived holistically, a phenomenon best illustrated when the processing of a
face feature is affected by the other features. Here, the authors tested the hypothesis that the …

Facial expressions are key to social interactions and to assessment of potential danger in
various situations. Therefore, our brains must be able to recognize facial expressions when …

What may be special about faces, compared to non-face objects, is that their neural
representation may be fundamentally spatial, eg, Gabor-like. Subjects matched a sequence …

The present study investigated the role of size and view on face discrimination, using a
novel set of synthetic face stimuli. Face discrimination thresholds were measured using a …

This study examined the extent to which letter optotypes and grating stimuli provide
equivalent measures of contrast sensitivity under conditions designed to favor the …

Previous work has shown an advantage of middle spatial frequencies (SFs) in face
recognition. However, a few recent studies have suggested that this advantage is reduced …

Evolutionary survival and procreation are augmented if an individual organism quickly
detects environmental threats and rapidly initiates defensive behavioral reactions. Thus …

Several lines of evidence suggest that the image statistics of the environment shape visual
abilities. To date, the image statistics of natural scenes and faces have been well …
