We studied the effects of a Learning Station on the completion and accuracy of math homework of middle school students who had chronic homework problems. The Learning Station was a three sided free-standing panel with theoretically and empirically-based components involving (a) stimulation (color, music, activity breaks, and choice) and (b) self-attention (mirror and self-monitoring). Two students who used the Station tripled their accuracy and the amount of homework completed as assessed in a multiple baseline across participants design. One student with high academic abilities elected not to use the intervention, because he worked quickly (albeit carelessly) at school to complete his homework during baseline and during intervention. The practical and research implications of the findings are discussed. 相似文献

Williams syndrome (WS) is a rare genetic disorder that results in severe visual-spatial cognitive deficits coupled with relative sparing in language, face recognition, and certain aspects of motion processing. Here, we look for evidence for sparing or impairment in another cognitive system-object recognition. Children with WS, normal mental-age (MA) and chronological age-matched (CA) children, and normal adults viewed pictures of a large range of objects briefly presented under various conditions of degradation, including canonical and unusual orientations, and clear or blurred contours. Objects were shown as either full-color views (Experiment 1) or line drawings (Experiment 2). Across both experiments, WS and MA children performed similarly in all conditions while CA children performed better than both WS group and MA groups with unusual views. This advantage, however, was eliminated when images were also blurred. The error types and relative difficulty of different objects were similar across all participant groups. The results indicate selective sparing of basic mechanisms of object recognition in WS, together with developmental delay or arrest in recognition of objects from unusual viewpoints. These findings are consistent with the growing literature on brain abnormalities in WS which points to selective impairment in the parietal areas of the brain. As a whole, the results lend further support to the growing literature on the functional separability of object recognition mechanisms from other spatial functions, and raise intriguing questions about the link between genetic deficits and cognition. 相似文献

Based on terror management theory, the authors suggest that ambivalent reactions to the human body are partially rooted in the association of the physical body with inescapable death and that individuals high in neuroticism are particularly vulnerable to such difficulties. Three experiments demonstrated that priming thoughts about one's death leads individuals high in neuroticism to flee from physical sensations, including pleasurable ones. In response to mortality salience, highly neurotic individuals spent less time submerging their arm in ice-cold water and using an electric foot massager but did not avoid stimulation in nontactile modalities (i.e., listening to music). The discussion highlights the role of existentially motivated self-repression in inhibitions surrounding the body. 相似文献

Following exposure to experimenter-provided examples of space creatures, people tend to conform to the features contained in the examples when creating their own novel space creatures. In three experiments, we manipulated factors known to affect source-monitoring accuracy to determine how these manipulations would influence conformity to experimenter-provided examples. In Experiment 1 we altered people's cognitive agenda by means of the instructions given before the drawing task. In Experiment 2 we examined how time pressure would affect the level of conformity, and in Experiment 3 we manipulated the availability of the creatures during the drawing task by making them available to half the participants. Conformity decreased when extended source-monitoring processes were engaged and increased when these processes were disrupted. The results from the three experiments were consistent with the principles of the source-monitoring framework. 相似文献

We examine production of word definitions by people with probable Alzheimer's disease (pAD). In the first experiment, healthy young adults defined concrete, imageable nouns to provide a baseline of definitional ability. Analysis of these definitions identified the key defining features of each target item. In the second experiment, pAD participants and elderly controls produced definitions of the same items. In the third experiment, healthy young participants rated the adequacies of these definitions. Although as expected the pAD participants produced fewer good definitions than the other two groups, most of their responses still contained some relevant information. pAD definitions contained fewer pieces of information and the information they produced was more tangential to the primary concept than that provided by the young or elderly participants. We identify two possible explanations in semantic loss and metalinguistic impairment. We consider metalinguistic impairment to provide the more plausible explanation of pAD patients' definitional performance. 相似文献

In this article we describe a project which aims to ensure prevention and continued protection from violence for family members. We outline our theoretical approach to assessment and working with violence in family relationships and the associated ethical problems. We identify three recurrent themes: risk, collaboration, and responsibility. We focus on our work with couples, where the man is violent towards the woman. Within this discussion we identify other important clinical issues. 相似文献

We examined the effects of different labelling patterns on the generalization of object names. Two‐year‐olds, three‐year‐olds and adults were shown two ‘standard’ objects, which were named with the same label, or with two different labels, or with no label at all. Participants were then asked whether objects morphed to be intermediate to the standards belonged to one of the labelled categories or, in the No Label condition, were ‘like’ one of the standards. The Same Label condition showed generalization to all intermediates, whereas the Different Label and No Label conditions showed division of the intermediates into two separate categories, with somewhat sharper division under Different Label. These results suggest two possible mechanisms of lexical learning: ‘boosting’ the equivalence of different exemplars through label identity, and ‘differentiating’ the exemplars through differences in labelling. The studies provided strong evidence for boosting. Learners are sensitive to the distribution of labels across exemplars, and they hold powerful assumptions about the relationship between these distributions and the underlying naming space. These findings have implications for the early emergence of cross‐linguistic differences in lexical learning. 相似文献

A short-term group treatment model for gay male survivors of childhood sexual abuse living with HIV/AIDS 总被引:1,自引:0,他引:1

HIV-positive gay male survivors of childhood sexual abuse (CSA) face three layers of trauma: childhood abuse, homophobic oppression, and HIV/AIDS. Additionally, CSA has been shown to increase HIV risk behavior among gay men, and the trauma of HIV infection often parallels the experience of CSA. Effective coping strategies are particularly important for people living with HIV/AIDS in order to adapt to physical, psychological, and social implications of infection. However, coping strategies once adaptive in the context of CSA may become maladaptive in adulthood. Interventions are needed that enhance coping and address CSA for survivors living with HIV/AIDS to protect their own health and to prevent new transmissions. This article presents a group model found to be efficacious for treating gay male survivors of CSA living with HIV/AIDS. 相似文献

Williams syndrome (WS) is a developmental disorder associated with relatively spared verbal skills and severe visuospatial deficits. It has also been reported that individuals with WS are impaired at mathematics. We examined mathematical skills in persons with WS using the second edition of the Test of Early Mathematical Ability (TEMA-2), which measures a wide range of skills. We administered the TEMA-2 to 14 individuals with WS and 14 children matched individually for mental-age on the matrices subtest of the Kaufman Brief Intelligence Test. There were no differences between groups on the overall scores on the TEMA-2. However, an item-by-item analysis revealed group differences. Participants with WS performed more poorly than controls when reporting which of two numbers was closest to a target number, a task thought to utilize a mental number line subserved by the parietal lobe, consistent with previous evidence showing parietal abnormalities in people with WS. In contrast, people with WS performed better than the control group at reading numbers, suggesting that verbal math skills may be comparatively strong in WS. These findings add to evidence that components of mathematical knowledge may be differentially damaged in developmental disorders. 相似文献
