The purpose of the present study was to assess the effects of single- versus multiple-exemplar training with several artists’ paintings on graduate students’ stimulus generalization to novel paintings by the same artists. Six graduate students participated in this study. Participants studied decks of cards that depicted images of paintings by six different artists. Multiple-exemplar decks included three exemplars of three artists for a total of nine cards, and single-exemplar decks included single exemplars of three artists for a total of three cards. Participants “tested out” when ready following independent study with each deck and were required to score 100 % correct in order to move on to a generalization probe, during which participants were presented with novel exemplars. Overall, four of six participants performed better on the generalization probe after multiple-exemplar training, though in the case of three participants, only to a slight degree. These modest effects suggest that multiple-exemplar training may facilitate stimulus generalization, but that studying with single exemplars may allow for stimulus generalization as well. 相似文献

Previous studies examining lateralization of arm movements focused on supported movements in the horizontal plane, removing the effects of gravity. The authors hypothesized that interlimb differences in free reaching would be consistent with the differences shown during supported reaching. Kinematic and kinetic data were collected for the forearm and upper arm segments in a 3-direction reaching task. Results showed lateralization of coordination, reflected by initial movement direction and trajectory curvature. The nondominant arm showed increased initial direction errors, and path curvature associated with a timing deficit between elbow and shoulder peak torques. These coordination deficits did not disrupt final position accuracy. The authors conclude that nondominant arm coordination deficits are similar to those reported previously for horizontal plane movements. 相似文献

Abstract In the follow-up study of 4 children with acquired epileptic aphasia or Landau and Kleffner syndrome, dichotic listening studies evidenced a unilateral ear extinction. In the four cases, the dichotic extinction was contralateral to the temporal cortex involved in the generation of epileptic discharges during the active period of epilepsy. This pattern of dichotic performances persisted several years after the complete recovery from epilepsy and EEG normalization. The long-lasting dichotic extinction revealed a permanent dysfunction in the temporal auditory system that may be a consequence of the presence of an active epileptogenic focus during the critical period of functional differentiation of the temporal cortex. 相似文献

Recent research suggests that examining humor styles may contribute to our understanding of clinical problems, such as risk and resiliency. The goal of the current study was to examine whether humor styles moderate the association between social anxiety and depressive symptoms in an unselected sample. Three-hundred and six participants (66% female) at a large Southern US university completed self-report measures of humor styles and symptoms of social anxiety and depression. Regression analyses suggested that affiliative and self-defeating humor styles individually moderated the relationship between social anxiety and depressive symptoms. Clinical implications regarding the monitoring of humor use as a means of understanding the maintenance of depressive symptoms among socially anxious individuals are discussed. 相似文献

One measure of conceptual implicit memory is repetition priming in the generation of exemplars from a semantic category, but does such priming transfer across languages? That is, do the overlapping conceptual representations for translation equivalents provide a sufficient basis for such priming? In Experiment 1 (N=96) participants carried out a deep encoding task, and priming between languages was statistically reliable, but attenuated, relative to within-language priming. Experiment 2 (N=96) replicated the findings of Experiment 1 and assessed the contributions of conceptual and non-conceptual processes using a levels-of-processing manipulation. Words that underwent shallow encoding exhibited within-language, but not between-language, priming. Priming in shallow conditions cannot therefore be explained by incidental activation of the concept. Instead, part of the within-language priming effect, even under deep-encoding conditions, is due to increased availability of language-specific lemmas or phonological word forms. 相似文献

In what we term the orientation effect, faster spatial responses are made to the corresponding task irrelevant orientation of an object. We ask how this effect relates to object affordances, how attention may be involved, and how the effect relates to the better understood Simon effect. Two separate stimulus-response compatibility effects (an orientation effect and a Simon effect) were observed when spatial responses were made to photographs of objects whose orientation and location had been simultaneously manipulated. When attentional demands were high these separate effects were found using hand responses and foot responses, suggesting an abstract rather than specific coding of object affordances. However, when attentional demands were low only the Simon effect was observed, suggesting that, in order to obtain the orientation effect, objects must be represented at the level of an object. 相似文献

ABSTRACTThe current study (N?=?404) used a moderated moderation model to examine how gender, religious commitment, and self-stigma toward seeking psychological help may interact in the prediction of help-seeking attitudes. Bivariate zero-order correlations indicated that help-seeking attitudes was negatively associated with self-stigma of seeking help (r?=??.55) and positively associated with religious commitment (r?=?.14), and self-stigma was not significantly associated with religious commitment. Men reported more negative attitudes than women (ΔM?=??.18). Furthermore, multiple regression results revealed a three-way interaction such that the relationship between gender and help-seeking attitudes was moderated by both self-stigma and religious commitment. Specifically, men with high religious commitment and high self-stigma endorsed the most negative help-seeking attitudes, suggesting that religious men’s help-seeking attitudes may be particularly susceptible to the influence of self-stigma. Implications for research and the development of targeted interventions are discussed. 相似文献

Array Comparative Genomic Hybridization (array CGH) is a powerful tool for identifying genomic imbalances and providing a diagnosis in individuals with a normal karyotype. It has been particularly useful in the investigation of individuals with developmental delay +/?, dysmorphic features and/or multiple congenital abnormalities. However, this non-targeted method of scanning the whole genome can reveal unexpected information. We present a case where array CGH identified the cause of a proband’s moderate mental retardation by discovery of a de novo deletion of chromosome 3p25.3. This deletion was shown to contain at least 25 genes including the VHL gene, the deletion or mutation of which leads to Von Hippel Lindau (VHL) syndrome. Presymptomatic testing for VHL is usually offered after appropriate genetic counseling about the implications of this condition. Therefore, scanning the genome by array CGH presents a number of challenges for the genetic counselor. We suggest that further understanding of the psychosocial effects of array CGH is needed in order for appropriate pre- and post-test counseling to be provided. 相似文献
