Organisms 'discount the future' when they value imminent goods over future goods. Optimal discounting varies: selection should favour allocations of effort that effectively discount the future relatively steeply in response to cues promising relatively good returns on present efforts. However, research on human discounting has hitherto focused on stable(More)
Men take a proprietary view of women's sexuality and reproductive capacity. In this chapter, we (a) argue that sexually proprietary male psychologies are evolved solutions to the adaptive problems of male reproductive competition and potential misdirection of paternal investments in species with mistakable paternity; (b) describe the complex interrelated(More)

The rate of uxoricide (wife killing) in the United States, for example, is currently approximately five to ten times greater than in western Europe.

Hirschi and Gottfredson (1983) claim that the relationship between age and crime is similar in all social and cultural conditions and that no current sociological or crimi-nological theory can account for this similarity. We introduce the new field of evolutionary psychology and extend Daly and Wilson's (1988) work on homicide to construct a general theory(More)

We observed radio-implanted Merriam's kangaroo rats disposing of 10-g bonanzas of rolled oats in 48 trials in the field. The principal determinant of the initial disposition of discovered food was apparently its distance from the day burrow: food found within about 10m was mainly larder hoarded, whereas food encountered farther afield was usually dispersed(More)
BACKGROUND Intimate partner violence against women is prevalent and is associated with poor health outcomes. Understanding indicators of exposure to intimate partner violence can assist health care professionals to identify and respond to abused women. This study was undertaken to determine the strength of association between selected evidence-based risk(More)
