Reproductive experience induces changes in females. Parity-related differences in maternal treatment of offspring can induce enduring changes in offspring. The relationships between maternal experience, early social isolation, and development were explored in rodents in this experiment. Male rats were weaned from multiparous (MP) and primiparous (PP) mothers and placed into isolation or social housing for four weeks. They were then observed in a social-interaction test.

Patients with category-specific visual agnosia (CSVA) often exhibit a disproportionate difficulty recognizing objects from biological categories due (in part) to the fact that exemplars from biological categories tend to be visually and conceptually more similar. Similarity is often conceived of as a pairwise property (i.e., in terms of distance in a psychological space matrix), but may be more accurately conceived of as a setwise property (i.e., in terms of shared features).

The ORE is phenomenon whereby recognition for own race faces is better than recognition of other race faces. This study examines how non-perceptual factors—social context, attitudes, and experience—impact the ORE. Participants from three different racial groups (Caucasian, Black, Asian) completed a face recognition task screening faces for status-specific targets (baseline, perpetrator, victim), self-report measures of explicit bias and experience with members from other races and a measure of implicit bias. Results indicated that non-perceptual factors impact the ORE.
