The authors articulate 5 basic principles for enhancing incremental validity, both among elements within a test and between tests, during test construction: (a) careful, precise articulation of each element or facet within the content domain; (b) reliable measurement of each facet through use of multiple, alternate-form items; (c) examination of incremental validity at the facet level rather than the broad construct level; (d) use of items that represent single facets rather than combinations of facets; and (e) empirical examination of whether there is a broad construct or a combination of separate constructs. Using these principles, the authors offer specific suggestions for modifications in 3 classic test construction approaches; (a) criterion keying, (b) inductive test construction, and (c) deductive test construction. Implementation of these suggestions is likely to provide theoretical clarification and improved prediction. 相似文献

Childhood violence is a major public health and social policy concern in the United States. Scientists and policymakers alike have increasingly turned their attention to the causes of childhood violence and the extent to which its course can be modified through well-planned preventive interventions. However, it is not apparent that policymakers draw upon basic research findings in formulating their priorities and policies, nor is it apparent that developmental scientists incorporate policy considerations and prevention findings into their research frameworks and designs. The goal of this special issue on violent children is to begin to bridge the gaps among basic developmental science, prevention science, and public policy. 相似文献

A new general explanation for u-shaped backward masking is analyzed and found to predict shifts in the interstimulus interval (ISI) that produces strongest masking. This predicted shift is then compared to six sets of masking data. The resulting comparisons force the general explanation to make certain assumptions to account for the data. In this way, the experimental data promote the development of a new theory of backward masking. The new theory suggests interpretations of the data that are sometimes novel, often more precise, and sometimes contrary to interpretations that are prevalent in the literature. 相似文献

Three studies examined associations between goal disengagement, goal reengagement, and subjective well-being. In Study 1, 115 undergraduates reported on the extent to which they were able to abandon unattainable goals and reengage their efforts in alternative goals. Study 2 examined the importance of goal disengagement and goal reengagement in groups of young adults and older adults (N = 120). In Study 3, a sample of parents of children with cancer and parents of medically healthy children was examined (N = 45). The findings confirmed that goal disengagement and goal reengagement can be associated with ratings of high subjective well-being. In addition, the results showed that goal disengagement and goal reengagement can have interactive effects on subjective well-being. The importance of the findings for effective self-regulation and successful development are discussed. 相似文献

In this research, we investigated the degree to which brain systems involved in ignoring emotionally salient information differ from those involved in ignoring nonemotional information. The design allowed examination of regional brain activity, using fMRI during color-word and emotional Stroop tasks. Twelve participants indicated the color of words while ignoring word meaning in conditions in which neutral words were contrasted to emotionally negative, emotionally positive, and incongruent color words. Dorsolateral frontal lobe activity was increased by both negative and incongruent color words, indicating a common system for maintaining an attentional set in the presence of salient distractors. In posterior regions of the brain, activity depended on the nature of the information to be ignored. Ignoring color-incongruent words increased left parietal activity and decreased parahippocampal gyrus activity, whereas ignoring negative emotional words increased bilateral occipito-temporal activity and decreased amygdala activity. The results indicate that emotion and attention are intimately related via a network of regions that monitor for salient information, maintain attention on the task, suppress irrelevant information, and select appropriate responses. 相似文献

We used procedures based on response-restriction (RR) analysis to assess vocational and leisure activity preferences for 3 adults with developmental disabilities. To increase the efficiency of the analysis relative to that reported in previous research, we used criteria that allowed activities to be restricted at the earliest point at which a preference could be determined. Results obtained across two consecutive RR assessments showed some variability in overall preference rankings but a high degree of consistency for highly ranked items. Finally, we compared results of the RR assessment with those of an extended free-operant assessment and found that the RR assessment yielded (a) more differentiated patterns of preference and (b) more complete information about engagement with all of the target activities. 相似文献

Beyond abuse: the association among parenting style, abdominal pain, and somatization in IBS patients 总被引:2,自引:0,他引:2
This study assessed the relative strength of the association between abuse, negative parenting style, and somatization in irritable bowel syndrome (IBS) patients. Drawing from preclinical stress physiology and abuse research identifying the family social climate as a frequently stronger and independent determinant of long-term health effects than abuse-specific variables, we predicted that negative parenting behaviors would more strongly correlate with somatization than abuse. Subjects were 81 consecutively evaluated patients, who at baseline underwent psychological testing, measuring perceived parental style, abuse history, somatization, and pain. Although abuse correlated with maternal and paternal rejection, abuse was not associated with somatization. Higher levels of rejection and/or hostility among fathers (not mothers) were more strongly correlated with somatization than was abuse. Further, paternal parenting behaviors were more predictive of somatization than abuse, age, and gender. The lack of an association between abuse and somatization is discussed in light of limitations of biopsychosocial IBS models, whose strong focus on "pathological stressors" (e.g., abuse, trauma) as risk factors may overlook the importance of "less extreme" parenting variables in influencing somatic complaints. The relationship between parenting and somatization is discussed in the context of broader behavioral science research linking disruptions in the quality of parenting to dramatic and long-term changes in patterns of stress reactivity and brain abnormalities seen in IBS patients. 相似文献
