Pigeons were trained to discriminate the presence of one or more human forms in displays projected on a panel above the response key. This task was mastered, although imperfectly, with successive and with simultaneous presentations of positive and negative instances. The course of acquisition of the discrimination was similar for the two training procedures. Animals were able to transfer the discrimination from the successive to the simultaneous situation. Various tests were carried out to control for artifactual cues on which the discrimination might have been based. The discrimination was maintained when new displays were presented, when reinforcement was omitted, and when displays were inverted 180°. Animals were also able to discriminate between pairs of displays that were identical, except that one member of the pair contained a human form. The research extends the techniques used by Herrnstein and Loveland (1964), and confirms their finding that pigeons can master the concept of “person-present” in a visual display. 相似文献

Interventions that increase help‐seeking among people with depression have the potential to save lives. Several efforts have been impressively successful; however, research has also chronicled inconsistent results, with some endeavors indicating boomerang effects. The goal of the current analysis is to synthesize select findings from cognitive theorizing on depression with persuasion scholarship to explain how and why the combination of unfavorable attitudes toward help‐seeking, attitudes that are increasingly resistant to influence, psychological reactance, and cognitive errors can result in challenging responses to messages encouraging help‐seeking among people with depression. In addition, we highlight the importance of utilizing theory‐based approaches to circumvent resistance to persuasion and provide an explanation as to why the provision of immediate help‐seeking mechanisms could be a key aspect of successful intervention efforts. We also stress the importance of formative research and pilot testing, and warn against the potentially harmful error of assessing messages targeting people with depression on those without heightened levels of depressive symptomatology. Ideally, this effort will draw attention to the challenge of persuading people with depression to seek help and also motivate social psychologists to consider the ways they can use their craft to positively influence the health and well‐being of people with depression. 相似文献

National Guard (NG) soldiers returning from deployments in Iraq and Afghanistan were surveyed at 6 and 12 months following their return (N = 970). The overall prevalence of suicide risk at 6 and 12 months following their return was assessed, as were changes in suicide risk among soldiers initially at high or low risk. Factors associated with changes in risk were assessed. The percentage of NG soldiers with high suicide risk increased from 6.8% at 6 months to 9.2% at 12 months (odds ratio = 1.7, p = .02). In the 882 soldiers initially at low risk, 5.9% (52/882) became high risk at 12 months; in the 64 soldiers initially at high risk, 46.9% (30/64) became low risk at 12 months. Initial levels of depressive symptoms were predictive of changing to high risk; this association appeared to be partially explained by soldier reports of increased search in the meaning in life and higher levels of perceived stress. Because suicide risk increases over the first 12 months, continued risk assessments during this time period should be considered. Supporting soldiers to find meaning in their life after deployment and enhancing their capacity to cope with perceived stress may help prevent increases in suicide risk over time. 相似文献

Although religious and spiritual beliefs and practices have been frequently associated with greater psychological well-being among illness populations, little is known about the specific benefits individuals perceive they receive from these beliefs and practices. This issue was examined in interviews with 63 older HIV-infected adults. Participants reported a variety of benefits from their religious and spiritual beliefs and practices, including: (1) evokes comforting emotions and feelings; (2) offers strength, empowerment, and control; (3) eases the emotional burden of the illness; (4) offers social support and a sense of belonging; (5) offers spiritual support through a personal relationship with God; (6) facilitates meaning and acceptance of the illness; (7) helps preserve health; (8) relieves the fear and uncertainty of death; (9) facilitates self-acceptance and reduces self-blame. These perceived benefits suggest potential mechanisms by which religion/spirituality may affect psychological adjustment. 相似文献
