This study examined the effect of the variability of representation of durations in reference memory on temporal discrimination performance in children aged 5 and 8 years as well as in adults using a bisection (Experiment 1) and a generalization task (Experiment 2). In each task, the participants were familiarized before the blocks of tested trials with either the same referent duration values (fixed condition) or a distribution of referent duration values, with a mean equal to the referent durations used in the fixed condition and a .20 coefficient of variation (variable condition). The results showed that the sensitivity to duration was lower in the variable than in the fixed condition in the children and, to a lesser extent, in the adults. The modelling of the data indicated that this effect was due to the increase in the variability of the representation of durations in reference memory, but also to changes in the decisional processes. 相似文献

This experiment investigated temporal generalization performance in children aged 3, 5, and 8 years by using auditory stimulus durations where the standard was 0.4 s or 4.0 s, and non-standard stimuli were spaced linearly around the standard. At all ages, generalization gradients superimposed well when plotted on the same relative scale, indicating conformity to scalar timing. Whatever the standard duration used, the principal developmental changes were the increasing steepness of the generalization gradient with increasing age and a shift from symmetrical gradients, in the 3- and 5-year-olds, to adult-like asymmetrical gradients in the 8-year-olds. 相似文献

Diet, exercise, smoking, and substance use patterns affect the course of illness and quality of life for people with HIV. In interviews with a national probability sample of 2,864 persons receiving HIV care, it was found that most had made health-promoting changes in one or more of these behaviors since diagnosis. Many reported increased physical activity (43%) and improved diet (59%). Forty-nine percent of cigarette smokers quit or cut down; 80% of substance users did so. Desire for involvement in one's HIV care and information seeking-positive coping were the most consistent correlates of change. Other correlates varied by health practice but included health status, emotional well-being, demographics, and attitudes toward other aspects of HIV care. Most people with HIV improve their health behavior following diagnosis, but more might be helped to do so by targeting these behaviors in future interventions. 相似文献

Lateralized audiogenic seizure: motor asymmetries exhibited and the effects of interrupted stimulation 总被引:2,自引:0,他引:2
Sensitized SJL/J mice were monaurally tested for susceptibility to sound-induced seizure. The acoustic stimulation was interrupted for 15 s at various points during the biphasic pattern of running which these mice characteristically exhibit before seizing. Asymmetries of run directions and side of fall were noted. In addition, a dramatic reduction in seizure incidence was found when the interruption either extended into the period when the later burst of running would have occurred or began during this running burst. Finally, the results indicate that the latencies to the later running burst and the subsequent seizure are determined at or about the time of the onset of the first burst of running. 相似文献

The paper presents a core theory of human plausible reasoning based on analysis of people's answers to everyday questions about the world. The theory consists of three parts:
- 1 a formal representation of plausible inference patterns; such as deductions, inductions, and analogies, that are frequently employed in answering everyday questions;
- 2 a set of parameters, such as conditional likelihood, typicality, and similarity, that affect the certainty of people's answers to such questions; and
- 3 a system relating the different plausible inference patterns and the different certainty parameters.

Studied contributions of maternal psychological distress, family stress load, maternal and family risk factors, and family coping strategies in predicting behavior problems in 441 inner-city black primary-grade children. Results indicated maternal psychological distress and high family stress load were associated with high child behavior problems. Family coping strategies offered no protection against risk, while coping with life difficulties by reframing them was detrimental to child behavioral adjustment. Active help-seeking strategies (i.e., family mobilization, acquiring social supports) served to moderate the effects of maternal psychological distress and family risk attributes for boys, but exacerbated the effects of dysfunctional maternal social and psychiatric histories for girls. Implications for understanding vulnerability and resilience in inner-city black children and recommendations for future research are discussed. 相似文献
