When Practice Does Not Make Perfect: Effects of Strategic Cognitive Processes on Errors During Skill Development 下载免费PDF全文
This study looked at the contribution of strategic cognitive processes such as frequency gambling and speed and accuracy trade‐off in the production of errors during skill development. We developed a novel psychomotor task and trained participants on the task. We predicted that practice would change the nature of errors and be driven by strategic processes, rather than just change the overall number of errors. The first experiment investigated the effects of frequency gambling on errors during skill development by manipulating stimulus probability. The second experiment tested the separate effects of speed versus accuracy instructions to clarify the strategic contribution of response‐criterion setting. The results of these two studies refute the widespread assumption that skill development invariably reduces errors. Rather, errors can be a strategic feature of skill acquisition (e.g. gambling on low probability events), which, although results in speedy performance, would be a dangerous practice in many real‐life contexts.

ABSTRACTThis study examines the relationships between images of God, the imaginary and experiences of loss among Vietnamese immigrants living in Canada. One hundred twenty-nine participants completed four sets of questionnaires: a demographic questionnaire, a Questionnaire on God Image, the Brief Symptom Inventory, the Davidson Trauma Scale. In the second phase, 32 participants were administered the AT.9 test (an archetypal test with nine elements). In this test, participants are asked to draw, using nine symbolic elements, and then write a story based on their drawing. Results showed that a positive perception of God negatively correlated with somatisation, anxiety and hostility, whereas negative God image was significantly related to high levels of emotional distress. Results also showed that the synthetic categories of the imaginary were associated with a positive perception of God; and were negatively associated with somatisation, intrusion and hyper-vigilance. Further discussions on the main findings will address cultural implications in the fields of Mental Health, Religion and Culture. 相似文献

Expression of conditional fear without awareness has been previously demonstrated during delay conditioning, a procedure in
which the conditioned stimulus (CS) and unconditioned stimulus (UCS) overlap. However, less is known about the role of awareness
in trace fear conditioning, where an interval of time separates the CS and UCS. The present study assessed skin conductance
response (SCR) and UCS expectancy during delay and trace conditioning. UCS predictability was varied on a trial-bytrial basis
by presenting perithreshold auditory CSs. Differential UCS expectancies were demonstrated only on perceived delay and trace
trials. Learning-related SCRs were observed during both perceived and unperceived delay CSs. In contrast, differential SCRs
were demonstrated only for perceived trace CSs. These data suggest that awareness is necessary for conditional responding
during trace, but not delay, fear conditioning. 相似文献

The purpose of the present study was to examine heart rate (HR) and affective reactions to state self-objectification as a function of gender. We examined negative affect, positive affect, guilt, and HR at 6-second and 5-minute intervals across baseline, control, high objectification, low objectification, and cologne conditions in men (n = 53) and women (n = 57). Mixed factorial MANOVA results indicated a statistically significant Gender × Condition interaction. Both men and women showed a cardiac orienting response to high versus low objectification. Cardiac stress reactions to objectification were higher among women. Negative affective reactions to objectification were more pervasive across conditions among women. 相似文献

In this article, we describe a systematic review of mean race and sex differences in situational judgment test (SJT) performance. On average, White test takers perform better on SJTs than Black, Hispanic, and Asian test takers. Female examinees perform slightly better than male test takers on SJTs. We investigate two moderators of these differences: loading of g or personality on the SJT, and response instructions. Mean race differences between Black, Hispanic, Asian and White examinees in SJT performance are largely explained by the cognitive loading of the SJT such that the larger the cognitive load, the larger the mean race differences. Regarding the effect of personality loadings of SJTs on race differences, Black–White and Asian–White differences are smaller to the extent that the SJT is correlated with emotional stability and Hispanic–White differences are smaller to the extent that SJTs are correlated with conscientiousness and agreeableness. Cognitive loading has minimal effect on male–female SJT score differences; however, SJT score differences are larger, favoring women, when SJTs are correlated with conscientiousness and agreeableness. Concerning response instructions, knowledge response instructions showed greater race differences than behavioral tendency instructions. The mean correlations show that these differences are largely because of the greater g loading of knowledge instructions. A second study showed that when used in hiring, SJTs are likely to have adverse impact by race but not by sex. 相似文献

Although individuals are known to be affected by concerns about relative position, little research investigates how neighbors’ wealth affects one’s hypertension risks. This paper investigates the relationship between neighborhood wealth and hypertension using both self-reported hypertension and objective hypertension. I find that self-reported hypertension rate substantially underestimates objectively measured hypertension rate. Consequently, while there is a positive, statistically significant relationship between neighborhood wealth and hypertension when using self-reported hypertension, the results based on measured hypertension data differ substantially, with the relationship only observed for people aged 55–65 but not for younger or older age groups. There is also evidence of a positive relationship between continuous blood pressure and neighborhood wealth for adult people (aged 30 or older). 相似文献

Opportunities to learn and apply new skills are generally considered a favourable job characteristic, but can there be too much of a good thing? In this paper, we draw on vitamin and resource perspectives to investigate a more nuanced perspective on where, when and why skill utilisation delivers value as a resource. Specifically, we examine whether skill utilisation exhibits non-linear relationships with job satisfaction and absenteeism in the presence of two different job demands: task workload, which captures the quantitative demands of work, and surface acting, which captures the qualitative demands of work. Using data from 278 hospital employees, we found that surface acting moderated the non-linear relationship between skill utilisation and absenteeism. Specifically, the relationship between skill utilisation and absenteeism became increasingly positive when surface acting was high, but not when surface acting was low. Interestingly, the linear relationship between skill utilisation and job satisfaction was less positive when surface acting was high. Task workload did not interact with skill utilisation to predict employee outcomes. Our findings highlight complexities in the relationship between job resources and demands and show that the value of skill utilisation changes under demanding conditions. 相似文献

Gelman and Echelbarger (2019—this issue) provide a valuable discussion about children's understanding of the inferred or nonobvious features of objects, which has implications for how children value products. We further this conversation by examining how children value products and brands as a means for meeting important goals, which we refer to as instrumental valuation. Specifically, we examine developmental trends in instrumental valuation for three goals—self‐concept development, self‐presentation, and happiness. Across these areas, we find that children place greater value on products and brands for meeting these goals as they grow older, particularly during late childhood and early adolescence. We conclude with a discussion of how age differences in instrumental valuation add to the general conversation about how children of different ages value objects. 相似文献
