People in long-term romantic relationships possess relationship maintenance mechanisms designed to protect against the temptation of desirable relationship alternatives. The current research examined the link between relationship maintenance mechanisms and an index of neurologically based approach/avoidance motivation. Participants completed a line bisection task that yields measures of asymmetric activity in the right and left frontal cortices; such activity is thought to reflect people's level of approach/avoidance motivation. Compared to single participants, participants in committed relationships displayed relatively less left visual field bias on the line bisection task (indicative of greater left frontal cortical activation and greater cognitive avoidance motivation) in response to available, attractive opposite-sex targets. Decreased left visual field bias was particularly pronounced among individuals with moderate levels of relationship commitment — those expected to display the highest levels of relationship maintenance. These findings provide insight into perceptual, motivational, and neurological processes that may help people avoid tempting relationship alternatives. 相似文献

A large number of studies have examined the finding that recognition memory for faces of one's own age group is often superior to memory for faces of another age group. We examined this own-age bias (OAB) in the meta-analyses reported. These data showed that hits were reliably greater for same-age relative to other-age faces (g = 0.23) and that false alarms were reliably less likely for same-age compared with other-age faces (g = -0.23). Further meta-analyses of measures of signal detection demonstrated that, although no difference in response criterion was evident (g = -0.01), discriminability was reliably better for same-age compared with other-age faces (g = 0.37). As well, children, younger adults, and older adults exhibited superior discriminability for same-age compared with other-age age faces. Thus, the OAB appears to be a robust effect that influences the accuracy of face recognition. Theoretical accounts of the OAB have generally suggested that it reflects more extensive, recent experiences with one's own age group relative to other-age groups. Additional analyses were supportive of this account as the OAB was present even for groups (e.g., older adults) that had prior experiences as members of another age group. However, the most comprehensive account of the OAB will also likely invoke mechanisms suggested by social-cognitive theories. 相似文献

The influence of match length and re-matching on the effectiveness of school-based mentoring was studied in the context of a national, randomized study of 1,139 youth in Big Brothers Big Sisters programs. The sample included youth in grades four through nine from diverse racial and ethnic backgrounds. At the end of the year, youth in intact relationships showed significant academic improvement, while youth in matches that terminated prematurely showed no impact. Those who were re-matched after terminations showed negative impacts. Youth, mentor, and program characteristics associated with having an intact match were examined. Youth with high levels of baseline stress and those matched with college student mentors were likely to be in matches that terminated prematurely, while rejection-sensitive youth and mentors who had previous mentoring experience were more likely to be in intact relationships. Implications for research and practice are discussed. 相似文献

Prior work has suggested that participants use a memory-for-past-tests (MPT) heuristic for judgments of learning (JOLs) in a multitrial learning scenario. That is, when learning the same material in multiple sessions, previous memory performance can be used as a basis for later memory predictions. We explored this issue by evaluating the impact of healthy aging on the use of MPT across trials. Young adults and healthy older adults learned pairs of words, made JOLs, and received a memory test in three study-test trials on the same material. Results indicated that both young and older adults relied on MPT as a basis for JOLs and changes in MPT across trials were nominal. Further, only the most-recent past test influenced JOLs, whereas earlier tests were unrelated to later judgments. JOLs were also influenced by prior-trial JOLs and were related to subsequent memory performance on the same trial. We suggest that these data support both indirect- and direct-memory mechanisms as the bases for the MPT heuristic. Further, in a multitrial learning scenario, in which the same information was being learned, young and older adults used the same bases for their JOLs. 相似文献

Social categorization is an early emerging and robust component of social cognition, yet the role that social categories play in children's understanding of the social world has remained unclear. The present studies examined children's (N = 52 four‐ and five‐year olds) explanations of social behavior to provide a window into their intuitive theories of how social categories constrain human action. Children systematically referenced category memberships and social relationships as causal‐explanatory factors for specific types of social interactions: harm among members of different categories more than harm among members of the same category. In contrast, they systematically referred to agents' mental states to explain the reverse patterns of behaviors: harm among members of the same category more than harm among members of different categories. These data suggest that children view social category memberships as playing a causal‐explanatory role in constraining social interactions. 相似文献

In order to translate research findings into effective prevention strategies, it is important to understand people's beliefs about the causes of poor health outcomes. However, with the exception of knowledge and beliefs about folic acid supplementation, little is known regarding women's causal attributions women regarding birth defects. We employed Attribution Theory constructs to analyze open-text interview responses from 2,672 control mothers in the National Birth Defects Prevention Study who gave birth in 1997–2005. Common themes included use of alcohol, tobacco, illicit drugs, and medications during pregnancy. Stress and emotional upset were also suggested as possible causes of birth defects. Genetic- and heredity-related responses were more likely to be mentioned by Asian/Pacific Islander women compared to non-Hispanic Whites. Hispanic women were less likely to suggest several specific possible teratogens, such as paint, pesticides, or other chemicals, but were more likely to suggest events occurring during childbirth. Differences also emerged among ethnic groups for theoretical constructs, although most responses were categorized as controllable, changeable over time, and with an internal locus of causality. 相似文献

Although it is generally held that speed of processing declines with age, there have been few studies in which tactile temporal processing has been examined with older subjects. In the present study, temporal order judgments were obtained from a group of younger subjects (n = 28, mean age = 23.5 years) and a group of older subjects (n = 93, mean age = 69.8 years). The subjects judged the temporal order of two patterns presented to the same finger, four patterns presented to the same finger, and two patterns presented to different hands. Depending on the task, the average thresholds for the older subjects ranged from two to five times longer than the thresholds from the younger subjects. In absolute terms, the largest difference between the young and older subjects was seen in correctly identifying the order of four patterns, a difference of more than 500 msec. There was some support for the decline in temporal processing being due in part to a slowing in cognitive processing, and, depending on the task, in part to stimulus persistence and difficulty in pattern identification. 相似文献
