چکیده

of the physical target location, implying that the mean perceived target location is nearly coincident wi th the targe t. Thjs find ing means that perceived egocentric distance is quite accurate under full cues for the range of distallces studied. When visual cues to rustance are diminish ed , observers make systematic errors in their visually directed responding. When the target is closer than 2 m , they tend to respond to a more distant location, indicating that the perceived location is more dis tant; when the target is farther than 3 m, they tend to respond to a nearer location, indicating that the perceived location is closer. Under the same viewing conditions that lead to accurate visually illrected action, observers exhibit systematic errors in perceiving exocentric distances. We conclude that perceiving two locations without systematic error does not imply that the exocentric rustance between them is perceived without systematic error. Further evidence of a dissociation betwee n pe rceived location and perceived exocentric dis tance is provided by comparing monocular and binocular viewing. Whereas perceived location does not vary with the introduction of binocular cues (when monocular cues are sufficient for localization), perceived exocentric distance improves with the addition of binocular rusparity.

Hence, stepparents are expected to show less solicitude than genetically related parents, and this lack of genetic relatedness has been used to explain the higher frequencies of child abuse and homicide found in stepfamilies. However, oth...

An assessment of some proposed exceptions to the phenomenon of nepotistic discrimination against stepchildren

Stepparents commit child abuse and homicide at much higher rates than genetic parents. Proposed exceptions, including a recent claim that there is no such “Cinderella effect” in Swedish homicides, are shown to be mistaken. The hypothesis that only “mothers’ boyfriends” abuse children excessively, whereas married stepfathers do not, is tested and rejected in an analysis of Canadian homicides. De...

The evolution of intimate partner violence

a r t i c l e i n f o An evolutionary perspective anticipates predictable forms of sexual conflict in human mating relationships. Humans have evolved a psychology of tactical deployment designed to influence a partner's behavior to be closer to the actor's own optimum. Tactics are diverse, ranging from benefit-bestowing to cost-inflicting. We discuss adaptive problems toward which cost-inflicti...
