The study provides the first empirical evaluation of gender differences in psychological symptomatology and DSM-III-R major depressive disorder (MDD) across the first year following heart transplantation. An important goal was to identify physical health-related and psychosocial factors that could account for, or mediate, any association between gender and psychological distress. The sample for the present analyses was drawn from a larger cohort of 172 heart recipients and included all 28 women in the cohort plus 118 men who were matched demographically with the group of women. Detailed patient assessments were completed at 2, 7, and 12 months posttransplant. As expected, women's symptom levels were consistently higher than men's. However, while men's symptom levels in all areas declined with time posttransplant, women's distress in the area of depression initially improved but then worsened by the 12-month assessment. The distribution of episodes of MDD showed a temporal pattern of gender differences similar to that of depressive symptoms. The most important mediators of the gender-depression relationship were factors related to early posttransplant daily functional limitations: women reported more impairments in daily activities. Higher levels of such impairments, in turn, predicted subsequently higher depression levels by 12 months posttransplant. Several additional variables pertaining to transplant-related concerns and a low sense of personal mastery—while not serving as mediators—exerted their own independent effects on 12-month depression levels. The findings are relevant to the tailoring of educational and clinical interventions to the individual needs of women and men who receive heart transplants.Roberta G. Simmons, Ph.D., died on February 15, 1993, during data collection for this paper.  相似文献

The concept of representation plays a central role in philosophical and scientific theorizing about the mind, and according to the representational theory of mind (RTM), a wide variety of cognitive and perceptual capacities are best explained in terms of the occurrence and processing of mental representations. The concept of representation remains elusive, however, and there is no widespread agreement among philosophers or cognitive scientists over what it is for one thing to represent another. One reason for the lack of consensus is that philosophers and scientists deploy the concept in many different ways for many different purposes. Another reason for the lack of consensus is that, while it is generally agreed that a scientifically useful notion of representation should be informed and constrained by what we know about brains, there is disagreement over what contemporary neuroscience does or does not suggest about the nature of representation. This article discusses some of the key issues involved in developing a general theory of mental representation, in light of these divergent purposes and conflicting views.

Contrary to the findings from previous reviews we found little support for the general notion that greater amounts of participation in afterschool programs was related to academic, behavioral, or socio-emotional outcomes. However, some relationships did emerge depending on how participation was conceptualized and measured, and the methodology used to assess the relationship between participation and outcomes. For example, some benefits occurred when participants with high levels of participation were compared to non-participants, not when they were compared to other program participants. Several suggestions are offered to improve future research on the relationship between aspects of participation and developmental outcomes.  相似文献

We clarify the existing literature on gender differences in work sample exams by disentangling such differences on work sample exams from other predictors (e.g., situational judgment tests). In fact, we note that there are only two articles specifically related to gender differences in work sample exams. Based on theory and literature from social psychology, neuropsychology, and applied psychology, we propose that the three constructs of self‐concept, social skills, and writing skills are likely to influence work sample gender differences. We tested our hypotheses on two samples of managers. We found in one instance that males scored higher on a technical exercise, but there was stronger support for females, on average, scoring higher on exercises that involved social skills and on exercises that involved writing skills. Work samples that targeted a broad array of knowledge, skills, and abilities were associated with higher overall scores for females (ds of ?.37 and ?.34) and, thus, were unlikely to be associated with gender‐based adverse impact against females.  相似文献

The Behavior Rating Inventory of Executive Function (BRIEF) is a rating scale designed to assess executive functions in everyday life that is widely used in school and clinical settings and in research studies. It has been recently suggested, however, that the limited geographic stratification of the standardization sample renders the measure overly sensitive. We evaluated this hypothesis by examining BRIEF scores across studies of typically developing children and adolescents. Thirty-nine studies were identified that included at least one of three possible index scores. Mean scores across studies were (a) within one to two T-score units from the standardization sample mean of 50, (b) tended to be slightly lower than 50, and (c) were unrelated to geographic location (US Census regions or internationally). These findings refute recent claims that the BRIEF is overly sensitive and further add to the large body of literature supporting the validity of the measure.  相似文献

This paper considers two ways functions figure into scientific explanations: (i) via laws—events are causally explained by subsuming those events under functional laws; and (ii) via designs—capacities are explained by specifying the functional design of a system. We argue that a proper understanding of how functions figure into design explanations of capacities makes it clear why such functions are ill-suited to figure into functional-cum-causal law explanations of events, as those explanations are typically understood. We further argue that a proper understanding of how functions enter into design explanations of capacities enables us to show why two prominent objections to functionalism in the philosophy mind—the argument from metaphysically necessary effects (Bennett, 2007; Rupert, 2006) and causal exclusion (Kim, 1993, 1998; Malcolm, 1968)—are misguided when interpreted as posing a threat to functional explanation in science across the board. If those arguments pose a threat at all, they pose it to instances of (i); however, a great number of the functional explanations we find in psychology—and the sciences generally—are instances of (ii).  相似文献

The study investigated different types of awareness of memory dysfunction in dementia, specifically judgements concerning memory task performance or appraisal of everyday memory functioning and also exploring the neuropsychological correlates of such awareness. This was investigated in 76 people with dementia, comprising 46 patients with Alzheimer's disease (AD) and 30 patients with vascular dementia (VaD). The Memory Awareness Rating Scale (Clare et al., 2002, Neuropsychol Rehabil, 12, 341–362) was used, which includes an Objective‐Judgement Discrepancy (OJD) technique involving comparison of subjective evaluation of performance on specific memory tasks with actual performance, and a Subjective Rating Discrepancy (SRD) technique, which compares self versus informant judgement of everyday memory function. The AD and VaD groups showed lower awareness than a normal control group for both types of measures, the AD group showing less awareness than the VaD group on the OJD measure. Regression analyses supported associations for both groups between memory impairment and the OJD measure and between naming impairment and the SRD measure. The findings are discussed in terms of neurocognitive theories accounting for loss of awareness in dementia.  相似文献

The purpose of this research is to examine the comparability of mathematics and science scores for students from English language backgrounds (ELB) and non-English language backgrounds (NELB). We examine the relationship between English reading proficiency and performance on mathematics and science assessments in Australia, Canada, the United Kingdom, and the United States. The findings indicate a strong relationship with reading proficiency accounting for up to 43% of the variance in mathematics and up to 79% in science. In all comparisons, ELB students either outperformed NELB students or performed at the same level. However, when statistical adjustments were made for reading proficiency, in both mathematics and science, the score gap between the groups became statistically non-significant in three out of the four countries. These findings point to differences in score meaning in mathematics and science assessments and limitations in comparing performances of ELB and NELB.  相似文献
