通过虚拟现实构建虚拟三维场景,将二维平面视觉空间返回抑制范式应用到三维空间,通过两个实验操纵了目标深度、线索有效性以及视野位置三个变量,考察注意在三维空间不同视野深度位置上进行定向/重定向产生的返回抑制效应。结果发现,(1)二次线索化位于固定的中央视野时,不论目标出现在近处空间还是出现在远处空间,外周视野条件下的返回抑制大于中央视野条件下的返回抑制;(2)二次线索化位于非固定的中央视野时,近处空间和远处空间的返回抑制存在分离,表现为当目标出现在远处空间时,外周视野条件下的返回抑制效应减小。研究表明,三维空间中外周视野深度位置上的返回抑制与中央视野深度位置上的返回抑制存在差异。 相似文献

Recently the paleoanthropologist Pat Shipman has proposed what she calls the animal connection as the human trait that connects all other traits. Theologians and biblical scholars have proposed many relational, functional, and ontological interpretations of the image of God in humans and human nature, but have generally not included a connection with animals. Genesis 1–3, however, weaves human and animal creation in a variety of ways, and Adam's naming of other species implies they are understood as family or kin. Thus Genesis 1–3 understands a relationship with other animals as integral to human becoming and uses family or kinship as a root metaphor for human–animal relations. 相似文献

GABA‐A receptor is a transmembrane hetero‐oligomeric protein which consists of five subunits, the combination of which confers unique pharmacological properties to the receptor. It is well‐known that the GABAergic system is involved in the modulation of aggression. However, the role of α5/GABA‐A receptors has not been explored. In this study, we examined the effect of L‐655,708 (0.625‐5 mg/kg), a selective ligand for the benzodiazepine site of GABA‐A receptors which contain the α5 subunit, on agonistic behavior elicited by isolation in male mice. Individually housed mice were exposed to an anosmic “standard opponent” 30 min after drug administration, and the encounters were videotaped and evaluated using an ethologically based analysis. L‐655,708 (5 mg/kg) exhibited an ethopharmacological profile characterized by a marked reduction of the time spent in offensive behavior (threat and attack) without affecting immobility, accompanied by a significant increase of avoidance/flee and nonsocial exploration behaviors, suggesting that the antiaggressive effect of the drug is unselective. Overall, this behavioral profile might indicate the existence of an anxiogenic‐like activity of L‐655,708 in mice. Aggr. Behav. 30:319–325, 2004. © 2004 Wiley‐Liss, Inc. 相似文献

采用自编的组织心理所有权、基于组织的自尊和积极组织行为等有效量表调查45家生产型企业共2566名员工,以检测组织心理所有权、基于组织的自尊对积极组织行为的影响。结果发现组织心理所有权、基于组织的自尊和积极组织行为之间有显著的正相关,组织心理所有权、基于组织的自尊对积极组织行为有显著正向预测作用,其中基于组织的自尊在组织心理所有权与积极组织行为之间起显著的部分中介作用。尤其是对组织及个人声誉或成就的心理所有权感对员工积极组织行为各个因素有显著正预测作用,基于组织的自尊在投入行为、主动行为和谋取人际和谐行为上影响效应更为显著。这意味着增强员工组织心理所有权感,培育员工主人翁意识和组织归属感,重视基于组织的自尊,提升员工的组织价值感和自豪感等措施有利于提升企业组织和个体绩效。 相似文献

The aims of the present study were: (1) to assess the factor structure of the SATAQ-3 in Spanish secondary-school students by means of exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) models; and (2) to study its invariance by sex and school grade. ESEM is a technique that has been proposed for the analysis of internal structure that overcomes some of the limitations of EFA and CFA. Participants were 1559 boys and girls in grades seventh to tenth. The results support the four-factor solution of the original version, and reveal that the best fit was obtained with ESEM, excluding Item 20 and with correlated uniqueness between reverse-keyed items. Our version shows invariance by sex and grade. The differences between scores of different groups are in the expected direction, and support the validity of the questionnaire. We recommend a version excluding Item 20 and without reverse-keyed items. 相似文献

A most sensitive and specific electrophysiological indicator of selective processing of visual stimuli is the N2pc component. N2pc is a negative EEG potential peaking 250 ms after stimulus onset, recorded from posterior sites contralateral to relevant stimuli. Additional deflections preceding or following N2pc have been obtained in previous studies, possibly produced by specific stimulus features or specific prime-target sequences. To clarify the entire time-course of the contralateral- ipsilateral (C-I) difference recorded from the scalp above visual cortex in response to left-right pairs of targets and distracters, C-I differences were here compared between two types of stimuli and between stimuli that were or were not preceded by masked neutral primes. The C-I difference waveform consisted of several peaks, termed here P1pc (60-100 ms after target onset), N1pc (120-160 ms), N2pc (220-280 ms), and N3pc (360-400 ms). Being markedly enhanced when stimuli were preceded by the neutral primes, P1pc may indicate a response to stimulus change. Also, when stimuli were primed, N2pc reached its peak earlier, thereby tending to merge with N1pc. N3pc seemed to increase when target discrimination was difficult. N1pc, N2pc, and N3pc appear as three periods of one process. N3pc probably corresponds to L400 or SPCN as described in other studies. These observations suggest that the neurophysiological basis of stimulus-driven focusing of attention on target stimuli is a process that lasts for hundreds of milliseconds, with the relevant hemisphere being activated in an oscillating manner as long as required by the task. 相似文献

Current clinical models for addressing infidelity tend not to make social context issues a central focus; yet, societal gender and power structures, such as female responsibility for relationships and limited male vulnerability, affect the etiology of affairs and create power imbalances in intimate relationships. How therapists respond to these societal influences may either limit or enhance the mutual healing of both persons in the relationship. Thus attention to these societal processes is an ethical issue. This paper presents one perspective, the Relational Justice Approach, for working with infidelity. It places gender, power, and culture at the center of intervention in couple therapy, and includes three stages: (1) creating an equitable foundation for healing, (2) placing the infidelity in a societal context, and (3) practicing mutuality. Each stage is illustrated with case examples and contrasted with current practice regarding infidelity. 相似文献
