Despite the importance of persistence in early learning, we know little about how children reason about outcomes that result from their efforts. Here we examined the role of effort type (i.e., physical vs. cognitive) and intensity (i.e., high vs. low effort) in shaping children's decision making about effort-based rewards. Five- to 7-year-olds (N = 133) were assigned to one of four conditions (High Physical Effort, Low Physical Effort, High Cognitive Effort, Low Cognitive Effort) and completed a series of tasks to construct a toy. Tasks varied in the type (physical/cognitive) and intensity (high/low) of effort required to complete them. After constructing their toy, children completed a series of tasks to probe how much they valued that toy. Across conditions, children preferred their toy and gave it a higher monetary value, relative to a stranger's. However, when choosing their toy came at a cost, children no longer preferred it. Only children who built their toy through either cognitive or low effort were willing to incur a cost for their toy. Older children, across conditions, were also more likely to incur a cost for their toy. These findings demonstrate that by age five, children are sensitive to variations in effort type and intensity, and these factors shape how they evaluate effort-based rewards.  相似文献

When people face difficult life events, such as cancer or bereavement, they fare better when they receive support. These “experiencers” are likely to seek and receive support from a wide range of people, from close others to acquaintances. Indeed, the social support literature has long acknowledged the value of having a diverse support network. Research suggests that experiencers often perceive “weak ties” (i.e., acquaintances) as sources of support, and that experiencers sometimes prefer to get support from weak ties rather than strong ties. Providing support can be challenging for all kinds of supporters, however weak ties may be more likely than strong ties to allow worries about their inability to provide effective support to stop them from providing any support at all, thus depriving experiencers of opportunities for additional support. In this paper, we focus on the fact that often the provision of support occurs via a social interaction. We draw on the social psychology literature on minimal social interactions to suggest reasons why potential weak tie supporters might doubt their ability to provide effective support, and to generate advice to encourage potential supporters to reach out. Finally, we suggest future areas of research, with the ultimate goal of helping to expand the support that is available for people experiencing difficult life events.  相似文献

Nine subjects, 14 to 18 yr old, pulled a knob on a schedule of monetary reinforcement. Concurrently, they escaped or avoided periodic presentations of a tone by pressing a button that required 1.5 lb (6.67 N) of force or by punching a padded cushion that required 20 lb (88.96 N) of force. The punching response was designated as an aggressive response because the force of this response together with its topography was comparable to responses of humans that deface objects and produce escape or counter aggression from other humans. It was found that button pressing was the preferred concurrent avoidance response and there were few punches. However, when the monetary reinforcer was discontinued (extinction) punching increased for seven of the nine subjects, but there was no consistent change in the rate of button pressing. When the punching response was replaced by another non-preferred but non-aggressive response, neither this response nor button pressing increased during extinction. Hence, the increase in punching during extinction cannot be attributed solely to the fact that it was a concurrent response or a non-preferred response.  相似文献

The recent antagonistic but equally meritorious arguments concerning the nature of the adolescent necessitates a new framework of analysis which would incorporate these apparent antagonisms. Cursory observations indicate that more fruitful results may be obtained if the adolescent is equated to a member of a suppressed minority group. A comparison of the characteristics of the adolescent peer group to those of a suppressed minority group reveals some striking similarities.  相似文献

Confusion about the mandated reporting of child abuse was discovered in a case study to be widespread, including at the state level. Such extensive confusion serves to keep citizens from both seeing the depth of suffering to which children are subjected and responding appropriately to their suffering; and it serves to keep society dissociated from the impact violence has on us.  相似文献

Throughout history dreams have been primarily the province of religion. People in many cultures have looked to dreams as sources of spiritual insight and divine revelation. The relationship between traditional religious views of dreams and modern psychological views of dreams has long interested psychologists of religion—for dreams are a uniquely fertile subject for comparing religious and psychological understandings of human experience. In recent years there have been many revolutionary discoveries in dream research, discoveries that have taken us far beyond the seminal works of Freud, Jung, and the early sleep laboratory researchers. This essay describes the work of three leading contemporary dream researchers (neurophysiologist J. Allan Hobson, psychologist Stephen LaBerge, and anthropologist Barbara Tedlock) and evaluates the implications of their findings for our understanding of the religious dimensions of dreams. The essay concludes with some reflections on the valuable role of dream study in the psychology of religion. The primary claim is that recent dream research can make important contributions to current psychology of religion discussions about such issues as interdisciplinary inquiry, hermeneutics, the cross-cultural study of religious experience, the cultural and religious context of modern psychology, and the practical concerns of pastoral counselors.This essay is based on a paper presented on November 25 at the 1991 Annual Meeting of the American Academy of Religion, Kansas City, Missouri.  相似文献
