Infants' expressions of discrete emotions were coded during the more stressful episodes (4 through 8) of the Strange Situation at 13 and 18 months. The data showed a significant decrease in full-face expressions (more complex configurations of movements) and a significant increase in component expressions (simpler and more constrained patterns of movements). The authors interpreted this trend as a developmental change toward more regulated and less intense emotions. Consistent with this view, the aggregate index of infants' full-face negative emotion expressions, interpreted as reflecting relatively unregulated intense emotions, correlated significantly with maternal ratings of difficult temperament. The authors discuss alternative interpretations of the findings in terms of changes in reactivity/arousability and the emerging capacity for self-regulation.  相似文献

Raters who pursue different goals give different ratings   总被引:5,自引:0,他引:5  
J. N. Cleveland and K. R. Murphy (1992) suggested that phenomena such as rater errors and interrater disagreements could be understood in terms of differences in the goals pursued by various raters. We measured 19 rating goals of students at the beginning of a semester, grouped them into scales, and correlated these with teacher evaluations collected at the end of the semester. We found significant multiple correlations, both within classes and in an analysis of the pooled sample (adjusting for instructor mean differences, incremental R2 =.08). Measures of rating goals obtained after raters had observed a significant proportion of ratee performance accounted for variance (incremental R2 =.07) not accounted for by measures of goals obtained at the beginning of the semester.  相似文献

Two experiments evaluated the role of conditioned stimulus-unconditioned stimulus (CS-US) contingency in appetitive Pavlovian conditioning in rats. In both experiments, some groups received a positively contingent CS signaling an increased likelihood of the US relative to the absence of the CS. These groups were compared with control treatments in which the likelihood of the US was the same in the presence and absence of the CS. A trial marker served as a trial context. Experiment 1 found contingency sensitivity. There was a reciprocal relationship between responding to the CS and the trial marker. Experiment 2 showed that this result was not stimulus or response specific. These results are consistent with associative explanations and the idea that rats are sensitive to CS-US contingency.  相似文献

This study explored the prediction that cases with anterior communicating artery (ACoA) syndrome will exhibit deficits in higher-level language production and comprehension. A 65-year-old adult male with a history of ACoA syndrome was tested on higher-level linguistic tasks. The patient's performance on discourse comprehension. discourse production, and linguistic ambiguity comprehension tasks was impaired.  相似文献

The nature and extent of young caring in the UK continue to be a feature of a growing number of research programmes motivated by a children and carers' rights philosophy. However, the context in which young caring occurs as a result of parental ill-health or disability can only be fully understood by examining the findings and implications of medical research into parental impairment, and the social movements that have served to re-define the concept of 'disability' in society. This paper examines the arguments put forward by medical researchers, by those proposing a social model of disability and by those who have specifically investigated the conditions and experiences of young carers. It argues that children's caring roles within families where there is parental illness or disability need to be understood not only as a reflection of the nature of the medical condition itself, but as a consequence of complex family, social and economic processes. A 'whole family' approach is proposed, where the needs of children and parents are respected and responded to.  相似文献

Horn's distinction between--fluid intelligence (Gf) and visualization (Gv) was investigated with two Nonverbal Reasoning subtests from the Differential Ability Scales and three Simultaneous Processing subtests from the Kaufman Assessment Battery for Children. The sample comprised a predominantly Euro-American groups of 57 normal boys and girls between the ages of 6 and 12 years. Principal factor analysis yielded clear-cut Gf and Gv dimensions. The Gf factor was composed both of Differential Ability Scales and Kaufman-ABC subtests, suggesting that the construct of simultaneous processing is not merely a measure of Gv, as researchers have hypothesized, but also measures Horn's Gf fluid intelligence to a considerable extent.  相似文献

This essay considers ways in which Darwin's account of natural processes was influenced by economic, ethical, and natural-theological theories in his own day. It argues that the Anabaptist concept of "the gospel of all creatures" calls into question alliances between evolutionary theory and social policy that are based on the dominance of conflictual images such as "the survival of the fittest" and questions the negative images of both nature and God that Darwinism has been taken to sponsor. The essay also considers developments in biology that have called into question dualist accounts of human nature as body and soul, thus reminding us that we are fully a part of the natural world and thus contributing, in turn, to a better theological grasp of God's relation to nature.  相似文献
