Male and female rats were gonadectomized, implanted in adulthood with capsules containing either testosterone propionate (TP) or cholesterol, and were trained to lever press for access to an oestrous female. When lever press performance was tested in extinction, only the male rats implanted with TP displayed significantly higher levels of responding than controls, demonstrating that lever pressing for oestrous females as a reward is sexually dimorphic. Ejaculation patterns from a separate assessment of these rats' copulatory ability were significantly correlated with their instrumental performance. In a second experiment, "masculinized" females exposed to TP postnatally and given TP implants responded in extinction at mean levels equivalent to those exhibited by adult males that were either intact or castrated with androgen replacement. These data suggest that organizational steroid exposure perinatally affects the actual reward value assigned to oestrous females inadulthood, in combination withconsummatory sexual experience. 相似文献

ABSTRACT: In the United States each year the equivalent of an average-size medical school graduating class commits suicide, with the highest incidence occurring in the decade following the completion of training. Of these suicides, 20% to 30% are associated with drug abuse and 40% with alcoholism. Various problem areas are considered. Role strain, leading to excessive drug use in an attempt to increase work efficiency, is coupled with a denial of the physician's own dependency needs and gratification. The problem of identity occurs in relation to the exaggerated sense of duty and obligation the physician feels in attending to the demands of the patients and their families. Medicine as magical thinking is also discussed, revealing the physician's belief in his own immunity, which is strenuously tested when he actually sets up in practice. The community's high regard for the physician further complicates the situation. Too little has been done about working with emotional problems of medical students during their training and after they begin to practice. Unfortunately, physicians feel uncomfortable in turning to colleagues for help; rather, they tend to isolate themselves, resorting to alcohol and drugs. One should question the selection of medical students and their overall training, not only in terms of academic learning but also with more consideration for the stresses and strains of the future career. 相似文献

AbstractBenatar’s central argument for antinatalism develops an asymmetry between the pain and pleasure in a potential life. I am going to present an alternative route to the antinatalist conclusion. I argue that duties require victims and that as a result there is no duty to create the pleasures contained within a prospective life but a duty not to create any of its sufferings. My argument can supplement Benatar’s, but it also enjoys some advantages: it achieves a better fit with our intuitions; it does not require us to acknowledge that life is a harm, or that a world devoid of life is a good thing; and it is easy to see why it does not have any pro-mortalist implications. 相似文献

The efficacy of inoculation theory has been confirmed by decades of empirical research, yet optimizing its effectiveness remains a vibrant line of investigation. The present research turns to psychological reactance theory for a means of enhancing the core mechanisms of inoculation—threat and refutational preemption. Findings from a multisite study indicate reactance enhances key resistance outcomes, including: threat, anger at attack message source, negative cognitions, negative affect, anticipated threat to freedom, anticipated attack message source derogation, perceived threat to freedom, perceived attack message source derogation, and counterarguing. Most importantly, reactance‐enhanced inoculations result in lesser attitude change—the ultimate measure of resistance. 相似文献
