This study examined the moderating effect of organisational culture (OC) moderation on the relationship between interpersonal trust (IT; trust in management and trust in peers) and employees’ affective commitment (AC). Participants were 295 employees of non-governmental organisations (NGOs) in Ghana (female = 42%; age range = 18–55). The employees completed the measures of IT, OC, AC, and employee performance. Moderation analysis of the data utilising structural equation modelling revealed that OC completely moderated the relationship between trust in management and trust in peers on AC. However, the moderation impact was found to be higher with trust in management than trust in peers. Moreover, AC completely mediated between trust in management and employee performance, and between trust in peers and employee performance. These findings highlight the importance for human resource managers of NGOs to incorporate and leverage on organisational culture as a key determinant resource for employees’ trust relationships, AC and performance goals. 相似文献

In this study, we developed a digitizing tablet-based instrument for the clinical assessment of human voluntary movements targeting motor processes of planning, programming and execution. The tool was used to investigate an adaptation of Fitts' reciprocal tapping task [10], comprising four conditions, each of them modulated by three indices of difficulty related to the amplitude of movement required. Temporal, spatial and sequential constraints underlying the various conditions allowed the intricate motor processes to be dissociated. Data obtained from a group of elderly healthy subjects (N=50) were in agreement with the literature on motor control, in the temporal and spatial domains. Speed constraints generated gains in the temporal domain and costs in the spatial one, while spatial constraints generated gain in the spatial domain and costs in the temporal one; finally, sequential constraints revealed the integrative nature of the cognitive operations involved in motor production. This versatile instrument proved capable of providing quantitative, accurate and sensitive measures of the various processes sustaining voluntary movement in healthy subjects. Altogether, analyses performed in this study generated a theoretical framework and reference data which could be used in the future for the clinical assessment of patients with various movement disorders, in particular Parkinson's disease. 相似文献

Recent evidence suggests that a common temporal representation underlies memory for serial order of items in a sequence, and the timing of items in a sequence. This stands in contrast to other data suggesting a reliance on only ordinal information in short-term memory tasks. An experiment is reported here in which participants were post cued to perform a comparison between a probe and study list of items irregularly spaced in time, on the basis of order or temporal information.Participants' performance on theserial recognition task was notaffected by the temporal proximity of items, although participants were able to use temporal information to perform a temporal recognition task. Application of a temporal matching model of serial and temporal recognition suggests that although participants were able to remember the timing of items, this memory for timing was unlikely to determine serial recognition performance. The results suggest a dissociation between ordinal and temporal information in short-term memory. 相似文献

In the centennial year of the birth of Hans Selye, this review compares his classical concepts of stress with a modern approach to mechanisms of CNS arousal. Relations between the two concepts are described. Neuroanatomical, neurophysiological, and functional genomic mechanisms underlying CNS arousal are briefly reviewed. Controls over stress responses and arousal are compared to particular concepts of control system engineering. Understanding these two systems is of crucial importance because their dysregulation is associated with large numbers of disease states. 相似文献

We find a spatially asymmetric allocation of attention in patients with traumatic brain injury (TBI) despite the lack of obvious asymmetry in neurological indicators. Identification performance was measured for simple spatial patterns presented briefly to a locus 5 degrees into the left or right hemifield, after precuing attention to the same (ipsilateral) or opposite (cross-hemifield) side. Though the cue was non-predictive of target location overall, performance was significantly slower for cross than for ipsilateral trials in both patients and controls. We tested 21 TBI patients without overt focal brain damage and nine control subjects. Only patients demonstrated significantly worse performance for left side presentation in the ipsilateral condition. Furthermore, in the cross-hemifield condition, the left-right difference seen in TBI patients was significantly larger-reflecting a failure in producing a leftward attention shift. Again no significant difference was found in controls. These hemifield effects suggest an asymmetry in the ability of TBI patients in shifting attention to the left hemifield, whether from central fixation or from a cue in the contra-lateral hemifield. The results support basic hypotheses regarding visual attention: Attentional control may be asymmetric and attention may be a distributed, rather than localized cortical function. 相似文献

Encoding under trust and distrust: the spontaneous activation of incongruent cognitions 总被引:1,自引:0,他引:1
Past studies of strategic thinking have shown that the encoding of the message information becomes more complex under distrust. Receivers process the information as if they are trying to protect themselves from being misled by testing alternative potential interpretations. The present study investigates the possibility that when people are mistrustful they spontaneously activate associations that are incongruent with the given message. Findings from 3 experiments suggest that, even when the distrust is unrelated in any meaningful way to the message and even when receivers are unable to prepare a strategic response, the cognitive system reacts to distrust by automatically inducing the consideration of incongruent associations--it seems designed to ask, "and what if the information were false?" The theoretical implications of the results for theories of social perception and persuasion are discussed. 相似文献

The effects of feedback equivocality, information availability, and prior decision-making history on escalation and persistence were investigated. Replicating the findings of J.L. Bragger, D.H. Bragger, D.A. Hantula, and J.P. Kirnan (1998), this study found that participants receiving equivocal feedback on their decisions invested more money and invested across more opportunities; those who could purchase information invested fewer resources than did participants who did not have the opportunity to purchase information. There was an inverse linear relationship between the percentage of opportunities in which participants purchased information and the delay to exit decisions and total resources invested. Six weeks earlier, some participants took part in a more profitable investment scenario, and prior experience led to later increased investing when participants were faced with failure, even above that invested in a preceding, succeeding scenario. These results are consistent with an equivocality theory account of escalation. 相似文献

Student prejudice against gay male and lesbian lecturers 总被引:1,自引:0,他引:1
The authors examined whether gay men and lesbians are evaluated more negatively than individuals of unspecified sexual orientation when attributional ambiguity surrounds evaluations and whether they are evaluated similarly to unspecified others when no attributional ambiguity is present. One male and one female lecturer delivered either a strong or a weak lecture to students who either (a) believed that the lecturer was a gay man or a lesbian or (b) did not receive sexual orientation information. Contrary to predictions, the quality of the lecture did not influence the ratings of known gay male and lesbian lecturers, although lecture quality strongly influenced ratings of lecturers whose sexual orientation was unspecified. After strong lectures, participants rated known gay male and lesbian lecturers more negatively than they did lecturers whose sexual orientation was unspecified. After weak lectures, participants rated known gay male and lesbian lecturers more positively than they did the others. The authors discussed the possibility that students might moderate their ratings to avoid discriminating against gay and lesbian lecturers. 相似文献
