Rape has been posited to be an outgrowth of male reproductive strategies. Forced copulations may have evolved as a consequence of the low parental investment made by males in producing and raising offspring. We designed a laboratory experiment which paired rhesus macaque males with females in order to assess the influence of intersexual aggression on male sexual activity. Younger and older adult males had comparable levels of sexual behavior, but younger males were more aggressive towards females than were older males. In addition, females threatened younger males more than older males. Male attacks on females did not result in sexual intercourse. On the contrary, a negative correlation existed between male aggression towards females and male success at achieving intromissions. Female aggression towards males appeared to be an effective tactic which reduced the chances of sexual intercourse. We conclude that intersexual aggression acts either as a mechanism of dominance assertion or as a means to increase spatial distance between individuals. These data do not support the idea that rape in humans has an evolutionary foundation derived from male reproductive strategies. 相似文献

In the course of a large epidemiological study in the region of Basle, Switzerland, from 1992 to 1996, a considerable rise in suicides assisted by the right-to-die society EXIT was uncovered after wide press coverage of an assisted double suicide of a prominent couple in that region in March 1995. Further investigation revealed that the rise of assisted suicides for a period of 2 years after the critical event was statistically significant compared to the 2 years previous to the double suicide. This was especially true for women older than 65 years. Hence, the almost enthusiastic kind of reporting about this event was apt to induce imitation suicides or a "Werther-effect." 相似文献

Existing literature suggests that graduate programs may not provide adequate training in working with suicidal clients. Therefore, we surveyed 238 predoctoral psychology interns and assessed the prevalence of clients engaging in suicidal behaviors and the amount of formal training in managing suicidal clients received. Results showed approximately 5% of participants indicated a client suicide and 99% indicated they had treated at least one suicidal client during their graduate training. In contrast, results demonstrated only 50% of the participants reported attending programs where formal training was offered. These findings suggest a continued need for increased formal training in managing suicidal clients in graduate psychology programs. 相似文献

Psychological, neuroscientific, and linguistic evidence suggests that a mental scene is in principle cognized with a mental gaze that can take on one of three forms: embodied physical gaze, embodied mental gaze, or disembodied mental gaze. Combinations of these forms also occur. A first sketch of the embodiment-disembodiment taxonomy that emerges from this threefold distinction is presented. 相似文献
