人力资源实践对员工创新行为的影响：心理契约破裂的中介作用及上下级沟通的调节作用

本研究选取了影响员工创新行为的组织（人力资源管理实践）、个体（对心理契约破裂的感知）及领导因素（上下级沟通）,通过402名企业员工的问卷调查,采用有调节的中介研究设计,对人力资源实践影响员工创新行为的机制进行研究。结果发现：（1）人力资源管理实践水平与员工创新行为正相关;（2）心理契约破裂在人力资源管理实践与创新行为关系间起部分中介作用;（3）上下级沟通水平调节了心理契约破裂与创新行为的关系,也调节了心理契约破裂对人力资源实践与创新行为关系的中介作用。     

Strategies in the Information Search Process: Interaction Among Task Structure,Knowledge, and Source

The authors explored the information search strategies of 145 individuals in the predecisional stage. Decision-making participants selected pieces of information from a list including relevant and irrelevant data. The authors investigated the influence of the individual's knowledge and information source. In Experiment 1, the authors experimentally manipulated the information source reliability. The results revealed that participants tended to use a sequential strategy when the authors presented information as supplied by a reliable source. In Experiment 2, the authors analyzed the interaction between information source and the individuals' knowledge. When participants believed the source to be reliable, even knowledgeable participants adopted a strategy as sequential as that chosen by naive individuals. In Experiment 3, a mediational model corroborated the hypothesis that the search strategy affects the final judgment. The results were consistent with the constructivist framework, which emphasizes the role of individual, task, and context in the decision-making process.     

The role of temporal context and expectancy in resource allocation to and perception of rapid serial events

The perception of target events presented in a rapid stream of non-targets is impaired for early target positions, but then gradually improves, a phenomenon known as attentional awakening. This phenomenon has been associated with better resource allocation. It is unclear though whether improved resource allocation and attentional awakening are a consequence of the temporal context, that is, the position of the target event in the stimulus stream, or are due to a simple expectancy or foreperiod effect. Expectancy is an alternative explanation of attentional awakening because it depends on the a posteriori probabilities, which will increase with target position when all target positions are equally likely. To differentiate between the expectancy and the temporal context account the a priori (objective) probability of target position was defined such that the a posteriori probability would be high for early and late, and low for intermediate target positions. EEG was collected and the P3 ERP evoked by target events was derived as an indicator of resource allocation. A robust attentional awakening effect was observed. The relationships between measures of performance and P3 amplitude, and respectively target position, a priori, and a posteriori probability were analyzed. Results showed that in contrast to target position, a posteriori probability had little impact on performance and did not moderate the association between P3 amplitude and performance. Results also indicated that in spite of the evident role of target position on resource allocation and the perception of target events in rapid stimulus streams, target position is likely not the only variable these are affected by. Nevertheless, the findings of the present study suggest that whereas the temporal context of a rapid serial event is a key player for resource allocation to and perception of the event, expectancy seems of very little consequence.

Knowledge of the world of work: A test of occupational information for young men

The study evaluates a test of occupational information administered to a national sample of 5000 young men, aged 14–24 in 1966, as part of the National Longitudinal Surveys of employment behavior. The predictive validity of the test score is assessed by reference to multiple regression analyses which confirm the significance of the score as an independent predictor of subsequent hourly earnings and occupational status. Correlation and factor analyses are used to examine the quality of the measurement instrument. All in all, the instrument is judged to exhibit desirable characteristics in terms of internal consistency reliability, discriminatory power, and level of difficulty. The test's reliability compares favorably with a commercially produced test designed to be used in counseling as a measure of occupational knowledge. With the possible modification of deleting a section relating to knowledge of earnings differentials, the test is commended to those involved in assessing and counseling the occupational choice process.     

Who Gets What and Why: Determinants of Social Allocations

Four experiments were conducted to explore how people allocate social resources between meritorious and needy parties. As predicted, participants with high social dominance orientation (SDO), who prefer hierarchical relationships in society, favored meritorious parties. In contrast, participants with low SDO, who value social equality, favored needy parties. Participants appealed to merit- or need-based ideologies to justify their allocations. Apparently, the notion of fairness denotes merit-based reasoning to people with high SDO, whereas it denotes need-based reasoning for those with low SDO. Among the participants, merit- and need-based ideologies were not simply post hoc rationalizations, but rather mediated the allocation decisions. Implications for the study of ideology and for theories of distributive justice are discussed.     

Mental fatigue influence on effort-related cardiovascular response: difficulty effects and extension across cognitive performance domains

Two experiments investigated cardiovascular effects of mental fatigue as a function of (1) the difficulty of the cognitive challenge with which participants were confronted, and (2) the relevance of that challenge to the activity that instigated the fatigue. In the first, participants performed an easy (fatigue low) or difficult (fatigue high) counting task and then were presented an arithmetic challenge (task B relevance high) or a scanning challenge (task B relevance low) with instructions that they would avoid a noise if they attained a modest performance standard. Analysis of blood pressure responses assessed during the work periods revealed fatigue main effects, reflecting stronger responses for High Fatigue participants, regardless of the character of the second task. In the second, the procedure was the same except that it included a high performance standard and provided the chance to win a prize. Analysis of the pressure data revealed fatigue x work period interactions, reflecting relatively stronger responses among High Fatigue participants in work period 1, but relatively weaker responses among these participants in work period 2. Results confirm previous findings and support an analysis of fatigue influence on effort and associated cardiovascular responses. They also argue against the idea that mental fatigue influence may be confined to relevant cognitive performance realms.
