The goal was analysis of the perceptual-cognitive skills associated with sport performance in orienteering in a sample of 22 elite and 17 nonelite runners. Variables considered were memory, basic orienteering techniques, map reading, symbol knowledge, map-terrain-map identification, and spatial organisation. A computerised questionnaire was developed to measure the variables. The reliability of the test (agreement between experts) was 90%. Findings suggested that competence in performing basic orienteering techniques efficiently was a key variable differentiating between the elite and the nonelite athletes. The results are discussed in comparison with previous studies. 相似文献

The objective of this study is to assess the impact on maternal anxiety of a short‐term intervention in a particularly stressful situation, such as a surgical anomaly diagnosed only at birth after repeated negative prenatal ultrasounds. The patients were 30 mothers of babies requiring surgical correction of a congenital anomaly who were randomly assigned to an intervention (N = 16) or control (N = 14) group. The intervention group received standard care plus short‐term intervention that included weekly meetings with the psychologist and weekly team meetings. The control group received only standard care available on the Neonatal Surgery Unit. The main outcome measure was maternal anxiety levels, assessed at birth and on discharge with the Spielberger State–Trait Anxiety Inventory (STAI–S). Statistical comparisons were made, and no significant differences were found at birth in the STAI–S scores of the two groups. At discharge, the intervention group exhibited a much lower STAI–S score than the group without short‐term intervention. The authors concluded that psychological counseling for parents of newborn babies has been shown to be helpful. However, the impact of such assistance was shown to be particularly beneficial for parents facing the emotional stress of their children requiring unexpected surgical corrections of congenital anomalies at birth. Therefore, the presence of a psychologist, as part of the standard care of newborns requiring surgical correction, is recommended. ©2003 Michigan Association for Infant Mental Health. 相似文献

Through two experiments, the study sought to emphasize the usefulness of the visual and kinesthetic imagery in mental practice. In Experiment 1, it was hypothesized that when the task to be learned through mental practice necessitates the reproduction of a form by drawing, the visual image, which provides a wide span of apprehension, is more suitable than the kinesthetic image. On the other hand, the kinesthetic image that supplies inputs from the muscles' positions and movements should be more appropriate for the acquisition of the duration of the drawing. In Experiment 2, it was hypothesized that the task, transformed into a motor task necessitating minute coordination of the two hands, would benefit more from kinesthetic imagery. To have optimal control over what was actually experienced during mental practice, the participants' imagery skills were measured. The participants also benefited from prior imagery training. The results demonstrate that when using mental practice to initially acquire a task, visual imagery is better for tasks that emphasize form while kinesthetic imagery is better for those tasks that emphasize timing or minute coordination of the two hands. 相似文献

To investigate how people anticipate and attempt to shape others' self-regulatory efforts, this work examined the impact of abstract and concrete mindsets on attention to goal-relevant aspects of others' situations. An abstract (relative to a concrete) mindset, by making accessible the cognitive operation of considering activities' purpose (versus process) was predicted to focus attention on how others' self-evaluative situations could impact others' long-term aims of self-knowledge and self-improvement, thus facilitating the anticipation and preference that others pursue accurate, even self-critical, feedback. Participants in an abstract (relative to a concrete) mindset both anticipated (Experiment 1) and suggested (Experiments 2a and b) that others pursue realistic rather than overly positive self-relevant information, with the latter effect apparently explained by the salience of abstract versus concrete goal-relevant features of others' situations (Experiment 2b). Implications for self-regulatory mindsets, as well as for interpersonal relations, are discussed. 相似文献

Desire for control (DC) or need for control has frequently been proposed as an important personality characteristic and as a possible crucial moderator within the fields of achievement, psychological adaptation, stress, and health. However, unlike locus of control, hardly any effort has been undertaken to assess the construct. An exception is the work of Burger and Cooper on the Desirability of Control Scale ( 1979 ). In the present study, the psychometric properties of a Dutch version of the DC scale were tested in three different samples (total N = 1044). Furthermore, relationships between DC, its subscales, and various psychological personality and outcome measures were examined. The results show that the psychometric properties of the original DC scale could be successfully transposed to the Dutch version. Furthermore, factor analyses (PCA) led to the construction of three reliable subscales: ‘control others’ (desire to be in charge of and control others), ‘control self’ (desire to control one's own life), and ‘relinquish control’ (desire to leave others in control). The pattern of relationships with convergent and outcome variables supports the interpretation of these subscales. For ‘control others’, as for the total DC scale (i.e. a total of all 20 items), the emphasis of these relationships was on dominance, active coping, and psychological adjustment. ‘Control self’ was mainly related to self‐sufficiency and independence, while ‘relinquish control’ was clearly associated with passive coping and poor psychological adjustment. In summary, the DC scale appears to be a psychometrically sound instrument to assess desire for control and its subdimensions. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

For any given number of factors, Minimum Rank Factor Analysis yields optimal communalities for an observed covariance matrix in the sense that the unexplained common variance with that number of factors is minimized, subject to the constraint that both the diagonal matrix of unique variances and the observed covariance matrix minus that diagonal matrix are positive semidefinite. As a result, it becomes possible to distinguish the explained common variance from the total common variance. The percentage of explained common variance is similar in meaning to the percentage of explained observed variance in Principal Component Analysis, but typically the former is much closer to 100 than the latter. So far, no statistical theory of MRFA has been developed. The present paper is a first start. It yields closed-form expressions for the asymptotic bias of the explained common variance, or, more precisely, of the unexplained common variance, under the assumption of multivariate normality. Also, the asymptotic variance of this bias is derived, and also the asymptotic covariance matrix of the unique variances that define a MRFA solution. The presented asymptotic statistical inference is based on a recently developed perturbation theory of semidefinite programming. A numerical example is also offered to demonstrate the accuracy of the expressions.This work was supported, in part, by grant DMS-0073770 from the National Science Foundation. 相似文献

We tested the hypothesis that the relationship between team climate and team performance is moderated by climate strength. The study sample was composed of 155 bank branches, and a two‐wave panel design was implemented. We measured four team climate facets (support, innovation, goal achievement and enabling formalization). We obtained two subjective indicators of team performance (ratings provided by team members and by team managers) and a financial indicator of team performance. Seven out of the 12 interaction effects tested were statistically significant and showed the expected sign. When financial team performance was the criterion, only the interaction term was significant. This suggests that only strong climates are related to financial team performance over time. 相似文献

ABSTRACT— How does the brain respond to statements that clash with a person's value system? We recorded event-related brain potentials while respondents from contrasting political-ethical backgrounds completed an attitude survey on drugs, medical ethics, social conduct, and other issues. Our results show that value-based disagreement is unlocked by language extremely rapidly, within 200 to 250 ms after the first word that indicates a clash with the reader's value system (e.g., "I think euthanasia is an acceptable/unacceptable…"). Furthermore, strong disagreement rapidly influences the ongoing analysis of meaning, which indicates that even very early processes in language comprehension are sensitive to a person's value system. Our results testify to rapid reciprocal links between neural systems for language and for valuation. 相似文献

The contribution of the dorsal subiculum (DS) and of the dorsal hippocampus (DH) to memory for distinct and overlapping visual stimuli was examined. Rats with selective lesions of the DS or the DH were compared to sham-operated rats on a delayed matching-to-place task guided by distal visual cues in a modified radial-arm maze. Overlapping distal visual cues could be perceived from three arm entrances (adjacent arms) and a unique set of distal cues were more likely to be seen from the other two arm entrances (distinct arms). Rats with DS lesions were impaired on trials with baited adjacent arms, but not on trials with baited distinct arms. Rats with DH lesions were impaired on both types of trials. These results suggest that the DS and the DH are necessary for pattern separation and that they may have different contributions to memory. 相似文献
