Rhesus monkeys were given 960 delayed response (DR) problems. The incentive was either visible or not visible during the baiting phase of each problem, and a 0-, 5-, 10-, or 20-sec intraproblem delay was imposed. Performance was substantially better when the incentive could be seen during the baiting phase. When the incentive was visible during baiting, at all stages of training performance decreased as a function of increased chance levels after short delays, and the rate of improvement with training was comparable after each of the four intraproblem delays. When the incentive was not visible during the baiting phase, an inverse relationship between performance and delay duration became evident only during the later stages of training. On the initial problems performance was at chance levels, and although improvement with training was evident, the rate of this improvement was inversely related to delay duration. The findings were interpreted in terms of Fletcher's orienting response analysis of DR performance. 相似文献

Loudness judgments of stimulus sets composed of four bursts of noise were analyzed for two types of contextual effects: between-set and within-set. Experiment I demonstrated between-set effects for these four-component stimuli; they were shown to be similar to those found in previous work with single stimuli. Experiment 2 tested an averaging model for within-set contextual effects. The results were inconsistent with the model. One interpretation is that there are within-set effects and that these are caused by shifts in the effective range of stimuli. Alternative interpretations attribute the apparent contextual effects either to an averaging of physical values or to an inappropriate scale of judgment. 相似文献

A history of childhood trauma exposure has been linked to the development of posttraumatic stress symptoms in adulthood following new exposure. Unhealthy coping behaviors that could develop or be utilized in response to early trauma could lend themselves to psychological issues in adulthood. Emotion-focused and problem-focused coping strategies in relation to stressful duty-related situations are examined as indirect pathways through which childhood trauma exposure could be associated with duty-related posttraumatic stress symptoms in 911 telecommunicators (N = 808). Multiple mediation models revealed that 3 of the 4 emotion-focused coping strategies, but not the problem-focused strategies, functioned as significant mediators in the association between childhood exposure and duty-related posttraumatic stress symptoms. Pairwise comparisons showed that self-controlling and escape-avoidance strategies were the strongest pathways of the indirect childhood trauma exposure–posttraumatic stress symptoms association. Implications of results regarding coping in response to new traumatic events in adulthood and potential research and intervention directions are discussed. 相似文献

Social–emotional comprehension involves encoding, interpreting, and reasoning about social–emotional information, and self‐regulating. This study examined the mediating pathways through which social–emotional comprehension and social behaviour are related to academic outcomes in two ethnically and socioeconomically heterogeneous samples totaling 340 elementary‐aged children. In both samples, social–emotional comprehension, teacher report of social behaviour, and academic outcomes were measured in a single school year. In both samples, structural equation models showed that the relationship between social–emotional comprehension and reading was mediated by socially skilled behaviour. In one sample, but not the other, the relationship between social–emotional comprehension and math was mediated by socially skilled behaviour. This paper advances our understanding of the mechanisms through which social–emotional factors are associated with academic outcomes. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献
