We offer a new theoretical angle for cognitive arithmetic, which is that evidence accumulation may play a role in problem plausibility decisions. We build upon previous studies that have considered such a hypothesis, and here formally evaluate the paradigm. We develop the finding that performance differences, due to variations in strategy use and aging effects, can indeed be reasonably explained through these accumulation-to-bound cognitive models. Results suggest that these models may be effectively used to learn more about the underlying cognitive processes. In this study, we modelled young (18–24) and older (68–82) adults’ solution times in performing arithmetic verification (e.g. whether 8?×?5?=?41 is true/false). The domain-relevant factors in strategy use (problem-verification heuristics) and aging differences (older/younger adult groups) were analyzed by a response process model of the latency data, that is fit by participant and item. Lower thresholds accounted for the faster response times (RTs) for problems solved with heuristics (arithmetic rule-violation checking strategies), as opposed to problems solved by calculation approaches. A more rapid accumulation accounted for faster RTs on problems in which two arithmetic rules were violated (strategy combination) rather than one. Third, higher thresholds (i.e. preferring to have greater certainty before responding) accounted for older adults’ slower speed. These findings are in support of accumulation models being relevant for more complex cognitive tasks, as well as to account for the age-related differences therein. 相似文献

The present study investigated the relative importance of two explanations behind perceptions of gender discrimination in hiring: prototypes and same-gender bias. According to the prototype explanation, people perceive an event as discrimination to the extent that it fits their preconceptions of typical discrimination. In contrast, the same-gender bias explanation asserts that people more readily detect discrimination toward members of their own gender. In four experiments (n = 797), women and men made considerably stronger discrimination attributions, and were moderately more discouraged from seeking work, when the victim was female rather than male. Further, a series of regressions analyses showed beliefs in discrimination of women to be moderately correlated with discrimination attributions of female victims, but little added explanatory value of participant gender, stigma consciousness, or feminist identification. The results offer strong support for the prototype explanation. 相似文献

Rate of Torque Development and Feedforward Control of the Hip and Knee Extensors: Gender Differences
Kristen M. Stearns-Reider 《Journal of motor behavior》2018,50(3):321-329
The purpose of this study was to determine whether women demonstrate decreased rate of torque development (RTD) of the hip and knee extensors and altered onset timing of the vastus lateralis and gluteus maximus during a drop-jump task when compared with men. On average, women demonstrated significantly lower normalized RTD of the hip extensors (women: 11.6 ± 1.3 MVT.s?1, men: 13.1 ± 0.9 MVT.s?1; p ≤ .01); however, there was no significant difference in knee extensor RTD. Women also demonstrated significantly earlier activation of their vastus lateralis (women: 206.0 ± 130.6 ms, men: 80.9 ± 69.6 ms; p ≤ .01) and gluteus maximus (women: 85.7 ± 58.6 ms, men: 54.5 ± 35.4 ms; p = .02). In both men and women, there was a significant negative correlation between the hip extensor RTD and the vastus lateralis electromyographic onset time (men: r = –.386, p = .046; women: r = –.531, p = .008). The study findings suggest that women may utilize a feedforward control strategy in which they activate their knee extensors earlier than men to compensate for deficits in hip extensor RTD. The impaired capacity to rapidly stabilize the hip and knee joints during dynamic maneuvers may contribute to the increased risk of anterior cruciate ligament injury observed in women. 相似文献

Transmission of reduction‐oriented crafting among colleagues: A diary study on the moderating role of working conditions 下载免费PDF全文

Zooming into reduction‐oriented job crafting among employees, next to minimizing demands (i.e., making a job less strenuous), we introduced optimizing demands (i.e., simplifying the job and making work processes more efficient) and suggested that optimizing demands should be positively related to work engagement, whereas minimizing demands negatively related to work engagement. Moreover, we suggested that both forms of reduction‐oriented crafting can be transferred among colleagues, and this will particularly occur in jobs that are high on demands (workload and emotional demands), low on resources (autonomy), and when the colleagues have a high‐quality relationship. We examined these hypotheses among 65 dyads of employees who filled in a general questionnaire and a diary for three working days. Multilevel analyses supported the transmission of both job crafting dimensions among colleagues. Moreover, there is more transmission of minimizing demands among colleagues when workload and emotional demands are high and autonomy is low. Additionally, optimizing demands was transmitted among colleagues when autonomy was low and quality of relationship with colleague was high. Optimizing demands was positively related to work engagement, whereas minimizing demands was unrelated to work engagement. These findings imply that optimizing demands is a favourable behaviour and can be transmitted among colleagues under specific conditions.
Practitioner points
- Working smarter is related to higher work engagement
- Employees model their colleague's proactive behaviour
- Unfavourable working conditions stimulate modelling behaviour of colleagues

Drawing on social comparison and equity theories, we investigated the role that perceived similarity of a comparison target plays in how resentful people feel about their relative financial status. In Study 1, participants tended to choose a comparison target who was better off, and they selected a target they perceived to be more similar than dissimilar along dimensions that surrounded their financial outcomes. In Study 1, perceived relative disadvantage was positively associated with resentment regardless of the perceived similarity of the comparison target. The results of Studies 2 to 5b clarified these findings by showing that being both similar and dissimilar to a target can cause resentment depending on the context. Using hypothetical and real social comparisons, we found that people are more dissatisfied with their financial outcomes when their comparative targets have the same background qualifications (i.e., are similar) but are financially better off (Studies 2, 3b, 4, and 5b). However, we also found that when the comparative financial contexts were similar (i.e., equal affluence), participants were more dissatisfied when their target for comparison had lower qualifications (i.e., was dissimilar; Studies 2, 3a, 4, and 5a). In all cases, perceptions of unfairness mediated the effects of social comparison on financial dissatisfaction. Taken together, these studies address some of the ambiguities around what it means to be similar to a target in the context of social comparisons of affluence, and they underscore the importance of perceived unfairness in the link between social comparison and resentment with one's financial status. 相似文献

Empirical studies on the relationship between affect and creativity often produce conflicting results. This inconsistency has led us to believe that the relationship between affect and creativity may be better understood by looking at potential moderators. Our study looked specifically at trait affect and self‐perceived creativity. Using the Affect Infusion Model (AIM) theory with problem clarity as the potential moderator, we hypothesized that when individuals are faced with problems that lack clarity, trait affect has greater sway over their self‐perceived creativity. Our results provided evidence that problem clarity moderated the relationship between positive trait affect and self‐perceived creativity; the positive relationship between positive trait affect and self‐perceived creativity is stronger when problem clarity is low and weaker when problem clarity is high. No moderating effect was found in the relationship between negative trait affect and self‐perceived creativity. 相似文献

Despite previous evidence showing a positive relationship between emotional intelligence (EI) and quality of life (QoL), associating older adults' emotional processing with several health indicators, few studies have explored both the IE and the a mechanisms through which they affect QoL. This cross-sectional study analyzes the mediator role of optimistic and pessimistic cognitive styles in the relationship between perceived EI (PEI) and QoL in 115 institutionalized older adults from Southern Spain. Regression analyses showed, after controlling for cognitive style, that PEI predicted a significant percentage of variance in: Health (β = .25, p < .01), Functional abilities (β = .20, p < .05), Activity and leisure (β = .17, p < .05) and Life satisfaction (β = .21, p < .05). Additionally, multiple mediation analysis revealed that cognitive style partially mediated the relationship between PEI and Health, Activity and leisure and Life satisfaction. Thus, PEI could promote personal but not external or environmental QoL aspects, highlighting the importance of developing emotional skills for healthy aging. 相似文献

Multiple object tracking (MOT) requires visually attending to dynamically moving targets and distractors. This cognitive ability is based on perceptual-attentional processes that are also involved in goal-directed movements. This study aimed to test the hypothesis that MOT affects the motor performance of aiming movements. Therefore, the participants performed pointing movements using their fingers or a computer mouse that controlled the movements of a cursor directed at the targets in the MOT task. The precision of the pointing movements was measured, and it was predicted that a higher number of targets and distractors in the MOT task would result in a lower pointing precision. The results confirmed this hypothesis, indicating that MOT might influence the performance of motor actions. The potential factors underlying this influence are discussed. 相似文献
