This paper studies the anticipatory nature of perception in relation to subjects' expertise in basketball. The two experiments conducted showed that experts encode game situations by automatically building a representation of the next‐likely state of the observed scene. In Experiment 1, subjects had to quickly compare pairs of configurations presented in succession. The results indicated that expert subjects differentiated the second configuration from the first less accurately and more slowly when the second configuration was the next‐likely state of the first, than when it was a possible previous state. In Experiment 2, subjects had to study game configurations and then perform a recognition task. The results showed that experts more often falsely recognized new configurations when they were the next‐likely state of an already‐encoded configuration than when they represented a possible previous state. Based on these results, we discuss the nature of expert knowledge, the integration of anticipatory components in perceptual processes, and the impact of expert knowledge on visual‐scene encoding and memorization.  相似文献

The study compares the impact of character strengths-based positive interventions in a sample of 178 adults. An experimental group that trained strengths of the Values-in-Action classification that typically correlate highly with life satisfaction (curiosity, gratitude, hope, humor, and zest) was compared in its gain in life satisfaction with a group that trained strengths that usually demonstrate low correlations with life satisfaction (appreciation of beauty and excellence, creativity, kindness, love of learning, and perspective) and a wait-list control group. If pre and post measures in life satisfaction were compared, the group with the strengths most correlated with life satisfaction improved significantly (statistically) in their satisfaction in comparison to a control group. This could be interpreted as support for the idea that primarily those strengths that correlate highly with life satisfaction should be addressed in strengths-based interventions. When asked for subjective ratings of well-being after the interventions concluded, participants in both intervention groups indicated gains above that of a wait-listed control group. Further analyses underscore the special role of self-regulation in facilitating success in the interventions. Overall, the data underline the potential of strength-based interventions for improving human well-being.  相似文献

ABSTRACT

Artistic creation often involves the use of mental images. This investigation examined the influence of training in artistic skills on mental imaging capacity in a sample of 126 subjects aged between 18 and 23 years. First- and 5th-year fine arts students were compared with regard to their performance in 2 imaging capacity tests (the Visual Elaboration Scale and the Vividness of Visual Imagery Test) and 3 tests of drawing involving spatial representation, transformation of spatial relations, and memory. The students who had undergone a longer period of artistic training performed significantly better on all 5 tests, and all drawing tasks scores correlated with each other. These results indicate that artistic training may enhance imaging capacity.  相似文献

The aim of this study was to examine the associations of control and vividness of mental imagery on performance in several components of in-depth drawing in a sample of fine arts undergraduates. The sample consisted of 56 second-year undergraduates (44 women and 12 men, mean age = 21.18 years) from the Fine Arts Faculty of Vigo University, Pontevedra, Spain. Participants were required to undertake a plastic art assignment focusing on the pictorial representation of space. Participants scoring high on the image control test obtained higher scores on the spatial analysis and in the formal construction of a work than participants with poor image control. Further research involving spatial image performance tests and mental image rotation tests is proposed.  相似文献

Although previous studies indicate that peer interactions represent an important component of the youth sport experience, studies examining peer interactions in the sport context are limited. Furthermore, the methodological tools commonly used to investigate peer interactions have restricted researchers’ understandings of the complex, reciprocal nature of these experiences. This paper outlines the potential contribution of a novel dynamic systems-based methodology, the state space grid method (SSG; Lewis, Lamey, & Douglas, 1999 Lewis, M. D., Lamey, A. V. and Douglas, L. 1999. A new dynamic system method for the analysis of early socioemotional development. Developmental Science, 2: 457475. [Crossref], [Web of Science ®] [Google Scholar]), to the study of peer interactions in sport. Concrete recommendations to guide the practical application of the SSG method to future peer research in youth sport are presented.  相似文献

We investigated the information that supports perception of whether an object is within reach using a locomotor task. Participants adjusted their own position relative to a fixed target by stepping or by propelling a wheelchair until they judged it to be within reach. The to-be-reached object was presented in virtual reality. The display of the target was driven in real time as a function of the observer's movement, thus depicting a stationary virtual object at a definite distance only through the relation across optical and nonoptical patterns of stimulation. We asked participants to judge the distance they could reach with their unaided hand or when holding a rod that extended their effective reach. They could see neither their body nor the rod thereby limiting available visual information about “reachability.” As expected, our results showed that despite the limited information that was available, participants' locomotor adjustments were influenced by (a) their simulated distance from the target, (b) their arm length, and (c) the presence or absence of the rod. The type of motion (stepping or wheelchair) had little influence. However, judgment accuracy was influenced by participants' initial simulated distance from the target. We compare the performance obtained in our locomotor judgment task with previous studies that have used different methods for measuring perceived reaching-ability. We discuss perceptual information that could have supported performance within the framework of the global array.  相似文献

Are risk-takers more likely to engage in unethical behaviors? We examined the relationship between risk-taking propensity and cheating in two experimental studies. In Study 1, we examined the relationship between subjects’ risk-taking propensity and their actual self-serving dishonesty using a gambling-like task. The results suggested that risk-taking propensity, measured using a behavioral approach, was positively correlated with actual self-serving dishonest behavior. In Study 2, we measured participants’ performances using a matrices test and found that the positive correlation still held. We found that participants with high risk-taking propensity reported a lower perceived probability of being detected, which might drive their dishonest behavior.  相似文献

ABSTRACT

Background and Objectives: Little is known how coping self-efficacy (CSE) interacts with coping in dyad everyday life. The present study examined the moderating role of daily CSE in the relationship between coping and the next-day positive (PA) or negative (NA) affect in patient-caregiver dyads, following hematopoietic stem cell transplantation.

Design: This intensive longitudinal study was conducted during the first 28 days after post-transplant discharge.

Methods: Patients and their caregivers (N?=?200) maintained daily diaries on CSE, coping strategies, and affect.

Results: Daily CSE moderated daily coping–affect relationship: Positive emotion-focused coping increased PA in patients with higher than usual emotion-related CSE, whereas a buffering effect was found at lower than usual emotion-related CSE. A positive association between negative emotion-focused coping and NA in both patients and caregivers was stronger among those with lower than usual levels of emotion-related CSE. Higher than usual instrumental coping reduced NA in patients whose caregivers had higher than usual problem-related CSE, but increased NA for those whose caregivers had lower than usual instrumental CSE.

Conclusion: The findings show that daily CSE contributes to the effectiveness of daily coping within dyad, confirming its significance in effective adaptation and the role in the dyadic coping process.  相似文献

Abstract

This study addressed the question whether the affect evoked by social comparisons and individual differences in social comparison orientation (SCO) may predict the development of burnout over a period of one year. The participants were 93 nurses (25 males and 68 females) who filled out a questionnaire twice, with an interval of about one year. Comparisons with others performing better than oneself (upward comparisons) were reported to occur more often, to evoke more positive affect, and to invoke less negative affect than comparisons with others performing worse than oneself (downward comparisons). Those who responded at Time 1 (T1) with more positive affect to upward comparison and with less negative affect to downward comparisons, showed a decrease in burnout at Time 2 (T2). In addition, those who responded with relatively more negative affect to upward comparisons at T1, showed an increase in burnout at T2, but only when they were high in SCO. It is concluded that in this population upward comparisons were more prevalent than, and evoked more favorable responses than, downward comparisons. The most important conclusion is that the affect evoked by social comparisons may predict future changes in burnout.  相似文献

The research aims were to compile and validate a multi-dimensional coping measure, taking African-centred coping behaviour into consideration. In a pilot study the Setswana-COPE (S-COPE) and the Africultural Coping Systems Inventory (ACSI) were administered to Setswana-speaking participants (N = 274). Selected items from these measures were combined into a single 35-item measure, the N-COPE, which was administered to another group of Setswana-speaking participants (N = 1050) together with a number of measures of psychological well-being. Reliability coefficients yielded a Cronbach alpha of.74 for the N-COPE total. Criterion-related validity was determined by correlating the N-COPE with other measures of psychological well-being. It was concluded that the N-COPE showed promising results for use in this context, but further refinement and validation is necessary.  相似文献
