People tend to recall more personal events from adolescence and early adulthood than from other lifetime periods. Most evidence suggests that differential encoding causes this reminiscence bump. However, the question why personal events are encoded better in those periods is still unanswered. To shed more light on this discussion, we examined memory for public events. Since it is often impossible to ascertain that queried events are equally difficult, we circumvented the issue of equivalence by calculating deviation scores for each trial. We found that participants more frequently answered questions correctly about events that occurred in the period in which they were between 10 and 25 years old. Furthermore, we found that the reminiscence bump was more pronounced for cued recall than for recognition. We argue that these results support the biological account that events are stored better, because the memory system is working more efficiently during adolescence and early adulthood. These results do not falsify the other accounts for differential encoding, because they are not mutually exclusive.  相似文献

The tau-dot hypothesis states that when tau-dot greater than or equal to -0.5, impact will be soft; when tau-dot < -0.5, impact will be "hard." Four experiments tested the usefulness of tau-dot for observers of collisions between 2 objects (rather than collisions between the observer and an object). Observers watched collisions depicted on a computer as 1 object approaching another. Results conformed to the tau-dot hypothesis and were consistent with previous research wherein observers watched collisions as participants. Results suggest that the information specifying collision severity is the rate of the relative rate of optical variation, a quantity that remains invariant over differing collision path trajectories and over differing perceivers (i.e., spectators or participants, viewing from different vantage points, moving or stationary).  相似文献

Compulsive sexual behavior (CSB) is defined as difficulties in controlling inappropriate or excessive sexual fantasies, urges, or behaviors that cause subjective distress or impairment in important areas of daily functioning. Using data from a baseline telephone interview, we examined the prevalence of CSB in a convenience sample of 820 postdeployed U.S. military male and female veterans and investigated correlates of CSB with sociodemographics and other mental health and sexual history characteristics. More men (13.8%) than women (4.3%) endorsed CSB-related symptoms. Given the limited sample size of women reporting CSB, correlational analyses were conducted only with men. After adjusting for significant sociodemographics, results indicated that gambling, suicidality, and sexually transmitted infections were significantly associated with male CSB. Current results suggest that CSB may be prevalent among U.S. military veterans post deployment and associated with significant negative health indices in men. CSB warrants attention regarding screening and intervention.  相似文献
