To ascertain whether there are ear-hemisphere asymmetries of selective attention, signal stimuli (tonal sequences) were presented monaurally with and without complex maskers (music and speech). The right ear-left hemisphere was more disrupted by language maskers; the left ear-right hemisphere was more disrupted by music maskers. These results suggest that there are hemispheric asymmetries of selective attention and that the ear hemisphere that usually processes a class of stimuli has greater difficulty filtering out those stimuli than does the nonspecialized hemisphere. 相似文献

Positional bias is a pattern of responding to a specific location that can be influenced by response effort and/or prior learning history. Prior research on positional bias within stimulus preference assessments have focused primarily on its use in paired stimulus assessments due to the complex nature of the multiple stimulus without replacement (MSWO) preference assessment. The present study is a secondary data analysis that utilized four different methods to measure side and center bias in a MSWO preference assessment for 19 young children with autism spectrum disorder. Participants displayed varying degrees of biased responding but collectively engaged in minimal biased responding. This study includes an analysis of the four methodologies, discussion of general patterns of responding, and general recommendations for the application of these methodologies in future research. 相似文献

This study investigated assessments of the acceptability of and negative relational implications for the reasons given for someone not providing emotional support. A representative sample of U.S. adults (N = 1598) participated in a survey experiment that included thinking of a person from whom they would expect such support, imagining that they did not receive support from this person, and being shown one of 16 reasons to explain the nonsupport. Participants evaluated that reason for its acceptability and its negative relational ramifications. As predicted, some nonsupport reasons were judged as more acceptable than were others, and they generated fewer negative relational ramifications. Participants who experienced nonsupport by a friend viewed their reasons as more acceptable than those experiencing nonsupport from family members. Despite this, greater negative relational ramifications were reported when friends compared to family members did not communicate support. Women's nonsupport was viewed as less acceptable compared to men's; however, there were no gender differences in the negative relational ramifications of nonsupport. When tested in a mediation model, acceptability mediated the relationship between expectations and negative relational ramifications, but there was also an unexpected direct negative effect between expectations and negative relational ramifications. 相似文献

The effects of bilateral microinjections of chlordiazepoxide and GABA into the central amygdalar nucleus on gastric ulcer formation induced by cold-restraint were examined in chronically implanted Wistar rats. Higher doses of chlordiazepoxide (20 and 30 micrograms/amygdala) significantly reduced stress ulcer development, whereas a lower dose (2.5 micrograms) produced a nonsignificant increase in ulcer severity. A similar dose/response pattern was observed following GABA administration. The benzodiazepine receptor antagonist Ro15-1788, applied to the amygdala, abolished the protective effects of both chlordiazepoxide and GABA. In addition, when Ro15-1788 (10 micrograms) was injected into the amygdala by itself, it aggravated the gastric stress pathology. However, a lower dose (5 micrograms) had an attenuating effect, opposite to the pattern of effects produced by chlordiazepoxide and GABA. The role of the amygdalar GABA-benzodiazepine receptor complex in stressful conditions is discussed. 相似文献

In this paper I argue that the conception of gender as illustrated in the Analects and the Mencius is basically a functional one that assigns women a domestic role. I show how this conception might imply the exclusion of women from the moral ideal of chun-tzu, which would result in the further subordination of women as wives to men as husbands in the context of the Confucian role system. On the other hand, I show how the Confucian role system can have a positive influence on the status of women through its elements of reciprocity and respect. Finally, I argue that the conception itself is not justified. 相似文献

SYPRENE, a new international Systemic Practice Research Network (PRN), has been established to fill the gap in practice-based research on the effectiveness and efficiency of strategic therapies. This article presents the rationale for the creation of SYPRENE and describes data collection methods, and the encoding system implemented within this PRN. More developments are expected in the recruitment of practitioners, the types of data collected, findings, and the implementation of SYPRENE in supervision, trainings, and professional schools. 相似文献

Michotte argued that we perceive cause-and-effect, without contributions from reasoning or learning, even in displays of two-dimensional moving shapes. Two studies extend this line of work from perception of mechanical to social causality. We compared verbal reports with structured ratings of causality to gain a better understanding of the extent to which perceptual causality occurs spontaneously or depends on instruction or context. A total of 120 adult observers (72 in the main experiment, 48 in an initial experiment) saw 12 (or 8) different computer animations of shape A moving up to B, which in turn moved away. Animations factorially varied the temporal and spatial relations of the shapes, and whether they moved rigidly or in a non-rigid, animal-like manner. Impressions of social as well as physical causality appeared in both free reports and ratings. Perception of physical causality was stronger than perception of social causality, particularly in free reports. No differences of this nature appear in infants and children, so the asymmetry may reflect learnt knowledge. Physical causality was relatively unspecific initially, but discrimination of causal and delayed control events improved with exposure to multiple events. Experience seems to affect the causal illusion even over a short timeframe; the idea of 'one-trial causality' may be somewhat misleading. Regardless of such effects on the absolute level of responses, the different measures showed similar patterns of variation with the spatio-temporal configuration and type of motion. The good fit of ratings and reports validates much recent work in this area. 相似文献

Three experiments tested preschoolers' use of abstract principles to classify and label objects by shape or function. Three- and 4-year-olds were instructed to match objects by shape or function. Four-year-olds readily adopted either rule, but 3-year-olds followed only the shape rule. Without a rule, 4-year-olds tended to match by shape unless object function was shown during matching (Experiment 2). Three-year-olds' ability to use a function rule was tested in several conditions (re-presenting functions; reminders to "use the rule"; repeating rule on every trial). None induced consistent function matching (Experiment 3). Supplemental memory and verbal tasks showed that 3-year-olds have trouble using function as an abstract basis of comparison. Naming data, however, show that preschoolers are learning that object labels are based on function. The results show preschoolers' growing flexibility in adopting abstract generalization rules and growing knowledge of conventions for extending words. 相似文献

This paper poses a feminist challenge to stage models of spiritual development and suggests alternative metaphors to the common image of a heroic journey. Women's spirituality is typically more intuitive and relational than rational and individualistic and to express this, we employ metaphors of the web and the quilt. Support for the relevance of these metaphors comes from the spiritual autobiography of Jane Goodall, an anthology of African American women's writings about spirituality, and two qualitative research investigations of older women's spirituality. We conclude with an autobiographical account of our own spiritual development and engage in a dialogue-on-the-page in which we respond to each other's narratives. 相似文献

Idiopathic dilated cardiomyopathy (IDC), a treatable condition characterized by left ventricular dilatation and systolic dysfunction of unknown cause, has only recently been recognized to have genetic etiologies. Although familial dilated cardiomyopathy (FDC) was thought to be infrequent, it is now believed that 30-50% of cases of IDC may be familial. Echocardiographic and electrocardiographic (ECG) screening of first-degree relatives of individuals with IDC and FDC is indicated because detection and treatment are possible prior to the onset of advanced, symptomatic disease. However, such screening often creates uncertainty and anxiety surrounding the significance of the results. Furthermore, FDC demonstrates incomplete penetrance, variable expression, and significant locus and allelic heterogeneity, making genetic counseling complex. The provision of genetic counseling for IDC and FDC will require collaboration between cardiologists and genetics professionals, and may also improve the recognition of FDC, the availability of support services, and overall outcomes for patients and families. 相似文献
