As volunteer organizations cannot rely on instrumental means to motivate their workers, we examine organizational commitment as a focal indicator of work motivation among volunteers. Based on a social identity analysis and previous work among paid employees, we argue that pride in the organization and respect from the organization predicts organizational commitment among volunteers. We further propose that among volunteers the perceived importance of volunteer work is an antecedent of pride, and that perceived support from the organization is an antecedent of respect. In this study among volunteer workers, Structural Equation Modeling (SEM) offers empirical support for our hypothesized model. In addition to the theoretical significance of developing a model that explains organizational commitment among volunteer workers, this study also has practical relevance, as it indicates that volunteer organizations might convey the importance of volunteer work and provide organizational support to induce pride and respect as a means of enhancing organizational commitment among their volunteers.

Human research has shown that lesions of the parietal cortex disrupt spatial information processing, specifically topological information. Similar findings have been found in non-humans. It has been difficult to determine homologies between human and non-human mnemonic mechanisms for spatial information processing because methodologies and neuropathology differ. The first objective of the present study was to adapt a previously established human task for rats. The second objective was to better characterize the role of parietal cortex (PC) and dorsal hippocampus (dHPC) for topological spatial information processing. Rats had to distinguish whether a ball inside a ring or a ball outside a ring was the correct, rewarded object. After rats reached criterion on the task (>95%) they were randomly assigned to a lesion group (control, PC, and dHPC). Animals were then re-tested. Post-surgery data show that controls were 94% correct on average, dHPC rats were 89% correct on average, and PC rats were 56% correct on average. The results from the present study suggest that the parietal cortex, but not the dHPC processes topological spatial information. The present data are the first to support comparable topological spatial information processes of the parietal cortex in humans and rats. 相似文献

The present research examined the effects of information sharing about self‐interest and group membership of the negotiation partner on negotiation cognitions, behaviors and outcomes. Study 1 (n = 77) showed that in anticipation of the negotiation, participants placed more trust in an in‐group member, and were more willing to exchange information with a negotiation partner who revealed his/her self‐interest. Study 2 (n = 80) examined how these effects influenced the development of attitudes and behavior during and after the negotiation. Results showed that negotiations with in‐group members were more cooperative when they shared, rather than not shared, information about underlying self‐interest. By contrast, negotiations with out‐group members were more cooperative when they did not share, rather than shared, information about their underlying self‐interest.

Previous research has demonstrated that intra-group respect can strengthen people’s group identification, and encourage them to exert themselves on behalf of their group. In the present contribution, we focus on the possibility that those who are not respected by other group members (i.e., the disrespected) can also display group beneficial behavior. Experiment 1 (N = 159) confirms this paradoxical premise and reveals that systematically disrespected group members indeed exert themselves on group-serving tasks. These findings were replicated in Experiment 2 (N = 110). Additional indicators in Experiment 2 demonstrate that the effort by systematically disrespected group members cannot be attributed to a desire to improve their acceptance in the group, but should be interpreted as attempts to assert the worth of the self separately from the group. Results are discussed in relation to the group-value model and insights on marginal group membership and social exclusion. 相似文献

Video-capture virtual reality (VR) systems are gaining popularity as intervention tools. To date, these platforms offer visual and audio feedback but do not provide haptic feedback. We contend that adding haptic feedback may enhance the quality of intervention for various theoretical and empirical reasons. This study aims to integrate haptic-tactile feedback into a video capture system (GX VR), which is currently applied for rehabilitation. The proposed multi-modal system can deliver audio-visual as well as vibrotactile feedback. The latter is provided via small vibratory discs attached to the patient's limbs. This paper describes the system, the guidelines of its design, and the ongoing usability study. 相似文献

Humans are experts at familiar face recognition, but poor at unfamiliar face recognition. Familiarity is created when a face is encountered across varied conditions, but the way in which a person’s appearance varies is identity-specific, so familiarity with one identity does not benefit recognition of other individuals. However, the faces of biological siblings share structural similarities, so we explored whether the benefits of familiarity are shared across siblings. Results show that familiarity with one half of a sibling pair improves kin detection (experiment 1), and that unfamiliar face matching is more accurate when targets are the siblings of familiar versus unfamiliar individuals (experiment 2). PCA applied to facial images of celebrities and their siblings demonstrates that faces are generally better reconstructed in the principal components of a same-sex sibling than those of an unrelated individual. When we encounter the unfamiliar sibling of someone we already know, our pre-existing representation of their familiar relation may usefully inform processing of the unfamiliar face. This can benefit both kin detection and identity processing, but the benefits are constrained by the degree to which facial variability is shared. 相似文献

Relationships between the endorsement of Western beauty ideals and practices and measures of hostility toward women and sexism were studied in 159 college men and 194 college women. The participants were predominately 18 or 19 years of age and of European American ethnicity. Correlations were computed between five factor analytically derived measures of beauty ideals and practices, two measures of the thin body ideal, and the following measures: Hostility toward Women Scale (HTWS; Lonsway & Fitzgerald, 1995), Attitudes toward Women Scale (AWS; Spence & Helmreich, 1978), and the two subscales of the Ambivalent Sexism Inventory (ASI; Glick & Fiske, 1996): hostile sexism (ASI-H) and benevolent sexism (ASI-B). It was found that endorsement of Western beauty ideals and practices was associated with hostility toward women, traditional sexism, hostile sexism, and, to a lesser extent, benevolent sexism. Results support feminist critiques of beauty practices as oppressive. 相似文献

The visual environment is highly regular, with particular objects frequently appearing in specific locations. Previous studies
of visual search have shown that people take advantage of such regularities, detecting targets more quickly when they appear
at a predictable location within a given spatial configuration. Moreover, this effect depends on implicit rather than explicit
memory for the configurations. These studies have suggested that implicit long-term memory for contextual information influences
the allocation of attention, modulating the flow of information through visual cortex. The present study used event-related
potentials to provide the first direct support for this proposal. We suggest that this guidance of attention by implicit memory
is important in the natural environment because it allows environmental regularities to influence perception without the intervention
of limited-capacity conscious processes. 相似文献

Parent delivered interventions based on applied behavior analysis (ABA) for children with Pervasive Developmental Disorders (PDDs) have been evaluated using primarily single‐subject design methodology or small case series. While the results of these evaluations are encouraging, an important next step is to standardize the interventions to allow for replication across sites, in studies with large samples and measures of long‐term, clinically meaningful outcomes such as improvements in children's functioning and their relationships with parents. Accordingly, the Research Units on Pediatric Psychopharmacology and Psychosocial Interventions (RUPP Autism Network) assembled a detailed manual for a structured behavioral parent training (PT) program, developed treatment fidelity and training procedures, and conducted a pilot, feasibility study. The PT program is part of a large scale, multisite study intended to determine the efficacy of combined pharmacological treatment and behavioral intervention to improve behavior and adaptive functioning in children with PDD. This paper discusses the rationale for this project. A companion paper provides the results of our feasibility study on the PT program. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

Following our hypothesis that juvenile emotional and/or cognitive experience should affect learning performance at preweaning age as well as adulthood, the present study in female Wistar rats aimed to examine the impact of (i) avoidance training at preweaning age, (ii) exposure to repeated maternal separation, (iii) the combination of both, and (iv) the blockade of dopaminergic neurotransmission on adult two-way active avoidance learning in rats. We found that preweaning, i.e. three week old, rats were less capable of avoidance learning compared to adults. Our main findings revealed that preweaning avoidance training alone improved avoidance learning in adulthood. Furthermore, maternal separation alone also improved avoidance learning in preweaning and in adult rats, but this effect of maternal separation did not add up to the beneficial effect of preweaning avoidance training on adult learning. In addition, the pharmacological blockade of dopamine receptors during preweaning avoidance training via systemic application of haloperidol impaired preweaning avoidance performance in a dose-dependent manner. Testing the haloperidol-treated preweaning presumed "non-learners" as adults revealed that they still showed improved learning as adults. Taken together, our results strongly support the hypothesis that emotional as well as cognitive experience at preweaning age leaves an enduring "memory trace," which can facilitate learning in adulthood. Our pharmaco-behavioral studies suggest that unlike the adult brain, preweaning learning and memory formation is less dependent on dopaminergic mechanisms, which raises the intriguing question of possible alternative pathways. 相似文献
