工作记忆表征能否引导视觉注意选择?目前实验结果尚不一致。有研究者认为能否观察到注意引导效应取决于视觉搜索类型。研究采用工作记忆任务与视觉搜索任务相结合的双任务范式, 结合眼动追踪技术, 对不同视觉搜索类型下的注意引导效应进行验证。实验1结果发现, 不管视觉搜索任务的靶子是否变化, 在早期的眼动指标上都发现了显著的注意引导效应, 但注意引导效应在靶子固定的视觉搜索任务下表现得更强。实验2在平衡两种视觉搜索任务中的工作记忆负载后发现, 两种视觉搜索任务下都出现了显著的注意引导效应, 但没有发现实验1中所出现的任务间差异。实验结果否定了视觉搜索类型对注意引导效应的决定性影响, 同时也提示工作记忆负载可能在注意引导效应中起重要作用。 相似文献

In our set of studies, we extended research on approach and avoidance motivations by investigating (i) motives in a work setting, (ii) interactions among approach and avoidance motives, and (iii) motives at implicit levels. Results of Studies 1 through 3 provided support for the construct validity of our work motives measure by demonstrating that approach and avoidance work motives are markers of more general approach and avoidance temperaments, they are distinct from other individual difference variables commonly studied by organisational psychologists (e.g. conscientiousness, regulatory focus and cognitive ability) and they are stable over time. In Studies 4 through 7, we confirmed our predictions that approach and avoidance motives predict employees' goal orientations, job appraisals and attitudes (e.g. job satisfaction and perceived support) and supervisor‐rated job behaviours (e.g. task performance and citizenship behaviour). Importantly, we provide the first empirical evidence that approach and avoidance motives interact to predict task performance and that the motives operate at implicit levels.

There is debate whether the social objectives met by banding can justify the loss in performance. To rationally assess this trade-off, one must know the magni- tude of performance lost. This article presents a mathematical model that allows computation of (a) the expected difference in performance between the top- ranked and bottom-ranked person in the band, and (b) the likelihood that the top-ranked person will actually outperform the bottom-ranked person, under various common testing situations. The model shows that, in most situations, a small loss in average performance may be expected, and that a person at the top of the band is only slightly more likely to actually outperform a person at the bottom of the band. The results support the use of banding and selection based on secondary criteria and generally show that the social gains of banding may be greater than the economic cost. 相似文献

Planning is fundamental to successful problem solving, yet individuals sometimes fail to plan even one step ahead when it lies within their competence to do so. In this article, we report two experiments in which we explored variants of a ball-weighing puzzle, a problem that has only two steps, yet nonetheless yields performance consistent with a failure to plan. The results fit a computational model in which a solver’s attempts are determined by two heuristics: maximization of the apparent progress made toward the problem goal and minimization of the problem space in which attempts are sought. The effectiveness of these heuristics was determined by lookahead, defined operationally as the number of steps evaluated in a planned move. Where move outcomes cannot be visualized but must be inferred, planning is constrained to the point where some individuals apply zero lookahead, which with n-ball problems yields seemingly irrational unequal weighs. Applying general-purpose heuristics with or without lookahead accounts for a range of rational and irrational phenomena found with insight and noninsight problems. 相似文献

This research examines the post‐purchase experience after choosing the most preferred brand versus a less preferred brand. When they experience positive product outcomes, those who chose their most preferred brand tend to give credit to the brand, whereas those who chose a less preferred brand attribute it to their smart choice. In contrast, with negative outcomes, those with the most preferred brand place the blame on themselves, whereas those with a less preferred brand blame the brand. Nevertheless, a silver lining emerges when brand attribution and satisfaction increase to the level of the most preferred brand after two consecutive positive experiences with a less preferred brand. Repeated positive experience could turn people's attention to more on good product quality of a less preferred brand than on cheaper price. 相似文献

In an educational setting, we examined the relationship of learning goal orientation with goal setting and performance over time. At the first time point, we assessed levels of trait learning goal orientation and asked participants to set performance goals. At each follow‐up time point, we reported to participants their current course grade and allowed them to revise their goals. Learning goal orientation was associated with both setting higher goals and maintaining higher performance over time. Additionally, the relationship of learning goal orientation and performance was found to be mediated by goal setting. 相似文献

Classical attribution theories of behavioral responsibility attribution emphasize that individuals should not be blamed for their mere association with a wrongdoer. Nonetheless, perceivers sometimes blame the wrongdoer's associates for the wrongdoer's misdeed even when those associates are not causally connected to the wrongdoing. In an experiment conducted in Singapore, we found that collective culpability attributions result from holistic thinking—the tendency to attribute causal connectedness between discrete entities or events. Activating holistic thinking enhanced perceptions of causal impacts of distal events and facilitated collective culpability attributions. We discuss these results in terms of their implications for understanding the nature of collective culpability and research on holistic thinking. 相似文献

The microstructures of 304 stainless steels with different amounts of nanocrystalline and microcrystalline austenite prepared by an aluminothermic reaction casting, without and with annealing at 1073?K for 8?h, have been investigated by X-ray diffraction, an electron probe micro-analyser, a transmission electron microscope and a scanning electron microscope. The steels, both without and with annealing, consisted of different dual nanocrystalline and microcrystalline austenite combinations and a little nanocrystalline δ ferrite, while the average grain size of the nanocrystalline austenite increased from 19 to 26?nm and volume fraction of the microcrystalline austenite increased from 17 to 30% after annealing. The tensile strength of the steel was dramatically increased from 500 to 1000?MPa and the tensile elongation ratio increased from 8 to 12% after annealing. However, the tensile strength was decreased to 600?MPa and the tensile elongation ratio increased from 12 to 22% after an annealing at 1273?K. The combination of dual nanocrystalline and microcrystalline austenite obtained after the annealing at 1073?K results in the best tensile properties. 相似文献
