Differentiating perfectionistic strivings and perfectionistic concerns, the present study examined how perfectionism predicts what coping strategies people use, when dealing with failures, and how perfectionism and coping influence people's satisfaction. A sample of 149 students completed daily reports for 3-14 days, reporting the most bothersome failure they experienced during the day, what strategies they used to cope with the failure, and how satisfied they felt at the end of the day. Multilevel regression analyses showed that perfectionistic concerns predicted more frequent use of self-blame, less frequent use of active coping and acceptance, and higher satisfaction at the end of the day, whereas perfectionistic strivings predicted less frequent use of self-blame and higher satisfaction. Although positive reframing, acceptance, and humor predicted higher satisfaction for all students, further analyses showed that positive reframing coping was particularly helpful for students high in perfectionistic concern. The findings suggest that accommodative coping strategies are generally helpful in dealing with personal failures, with positive reframing being a coping strategy that works particularly well for people high in perfectionistic concerns (who are prone to dissatisfaction) to achieve higher satisfaction at the end of the day.  相似文献

Healthy subjects adjust their grip force economically to the weight of a hand-held object. In addition, inertial loads, which arise from arm movements with the grasped object, are anticipated by parallel grip force modulations. Internal forward models have been proposed to predict the consequences of voluntary movements. Anesthesia of the fingers impairs grip force economy but the feedforward character of the grip force/load coupling is preserved. To further analyze the role of sensory input for internal forward models and to characterize the consequences of central nervous system damage for anticipatory grip force control, we measured grip force behavior in neurological patients. We tested a group of stroke patients with varying degrees of impaired fine motor control and sensory loss, a single patient with complete and permanent differentation from all tactile and proprioceptive input, and a group of patients with amyotrophic lateral sclerosis (ALS) that exclusively impairs the motor system without affecting sensory modalities. Increased grip forces were a common finding in all patients. Sensory deficits were a strong but not the only predictor of impaired grip force economy. The feedforward mode of grip force control was typically preserved in the stroke patients despite their central sensory deficits, but was severely disturbed in the patient with peripheral sensory deafferentation and in a minority of stroke patients. Moderate deficits of feedforward control were also obvious in ALS patients. Thus, the function of the internal forward model and the precision of grip force production may depend on a complex anatomical and functional network of sensory and motor structures and their interaction in time and space.  相似文献

The authors argue that F. Mechsner's (2004) perceptual-cognitive approach is an important contribution to the current discussion of motor control. Mechsner presents convincing evidence against direct motor control. Nevertheless, the mechanisms by which perceptual-cognitive representations determine efferent commands must still be clarified.  相似文献

Die Arbeit setzt sich drei Ziele: Sie will Grenzen und Einschränkungen aufzeigen, die im aktuell gebräuchlichen Störungsbegriff enthalten sind. Sie will zeigen, was verloren geht, wenn die Person des einzelnen Kranken, verstanden als Individualität, Subjektivität und Identität, in Diagnostik und Therapie zu wenig beachtet wird, und sie will darauf hinweisen, dass soziale, kulturelle und gesellschaftliche Faktoren in der Psychiatrie und Psychotherapie zu berücksichtigen sind. Methodisch bedient sich die Arbeit v. a. wissenschaftstheoretischer und philosophischer Argumente. Sie kommt zur Schlussfolgerung, dass die Grenzen von Diagnostik und Therapie in allen drei Bereichen eine gemeinsame Grundlage haben. Sie lassen sich überwinden, wenn Psychiatrie und Psychotherapie selbstreflexiv die Grenzen der eigenen Verfahren berücksichtigen und wenn Fremdheit und Andersheit (des Symptoms, des Mitmenschen, des kulturellen und gesellschaftlichen Umfelds) prinzipiell anerkannt werden. Der Text versteht sich als Kommentar zu D. Orlinskys Ausführungen zur störungsspezifischen Psychotherapie aus der Sicht des Psychotherapieforschers in diesem Heft.  相似文献

The choice of computer courses has a direct influence on the development of computer literacy. It is alarming, therefore, that girls seem to choose computer courses less frequently than boys. The present paper examines (a) whether these often-reported gender differences also occur at the early high school level (Study 1) and (b) how these differences can be predicted by applying an expectancy-value model to the domain of computing (Study 2). Both studies clearly show gender differences in the choice of computer courses in children between 10 and 16 years in the real-life situation of choosing courses at school. In Study 2, the suggested expectancy-value model is tested using data from 159 students and 137 parents. The model shows a good fit to the data, and the observed gender differences in the choice of computer course could be predicted by differences in the value placed on computers and the expectations of success. However, these differences could only be partly explained by differences in perceived parental attitudes, and there were only weak relationships between parental attitudes and the corresponding perceptions of the students. Educational implications of the findings and suggestions for future research are discussed.  相似文献

Scientific research findings are frequently picked up by the mainstream media, but it is largely unclear which factors have an impact on laypeople’s processing of the presented scientific information. In this study, we investigated the influence of cognitive and metacognitive inter-individual differences on recall and on critical evaluation of new scientific information that was presented in a journalistic article. Sixty-three participants (80 % female; mean age 24.1 ± 3.3 years) read a newspaper article reporting research findings on a recently developed and yet unproven treatment for depression. We found that more sophisticated, domain-specific epistemological beliefs and a higher cognitive ability were independently associated with better recall of content from the article. Additionally, participants with more sophisticated epistemological beliefs displayed a more critical evaluation of the article. Cognitive ability was unrelated to critical evaluation and to epistemological beliefs. There were also no interaction effects of cognitive ability and epistemological beliefs on recall or on critical evaluation. Based on our preliminary findings and previous evidence of epistemological beliefs as a modifiable feature, we discuss this inter-individual characteristic as a potential target for the promotion of better understanding of scientific topics by the general public.  相似文献

The study examined whether a behavior-change intervention focusing on self-regulatory strategies and emphasizing role model support increases physical activity (PA) among insufficiently active (not meeting PA guidelines of 150 min/week) cancer patients. Ambulatory cancer patients [N = 72; 54% female; M = 56 years, SD = 12.34; most with breast or colon cancer (34, 15%)] were enrolled in the MOTIVACTION-study, a 4-week intervention (1-hr counseling, followed by weekly phone calls), with pretest (T1), posttest (T2) and a 10-week follow-up (T3). Participants were randomized to either an exercise or to a stress management intervention (active control). The exercise intervention emphasized self-regulatory strategies (e.g. action- and coping planning and self-monitoring); patients were also encouraged to contact a physically active same-sex role model as a potential exercise partner. The active control condition consisted of coping and relaxation techniques. Sixty-seven patients remained in the study and completed the SQUASH assessment of PA and a measure of perceived stress. PA was validated by Actigraph accelerometry. At T2, 46% of the patients in the exercise group and 19% of stress management patients increased their activity levels to meet PA guidelines (>150 min/week; χ2(1) = 5.51, p = .019). At T3, participants in the exercise intervention maintained their exercise level (46%), but also 31% of the stress management patients met the guidelines. All patients reported reductions in perceived stress. Additional analyses comparing patients in the exercise group by role model contact (63% realized contact) revealed that those who had contact with their role model were significantly more likely to adhere to the recommended guidelines (T2:50%; T3:64%) compared to those who did not have contact with a role model (T2:39%; T3:15%), suggesting the potential of mobilizing role model support to facilitate PA. In sum, cancer patients may not only benefit from an exercise intervention emphasizing self-regulation, but also from stress management, regarding both reducing stress and increasing PA.  相似文献

Although Attneave (1954 Psychological Review 61 183 193) and Biederman (1987 Psychological Review 94 115-147) have argued that curved contour segments are most important in shape perception, Kennedy and Domander (1985 Perception 14 367-370) showed that fragmented object contours are better identifiable when straight segments are shown. We used the set of line drawings published by Snodgrass and Vanderwart (1980 Journal of Experimental Psychology: Human Learning and Memory 6 174-215), to make outline versions that could be used to investigate this issue with a larger and more heterogeneous stimulus set. Fragments were placed either around the 'salient' points or around the midpoints (points midway between two salient points), creating curved versus relatively straight fragments when the original outline was fragmented (experiment 1), or angular and straight fragments when straight-line versions were fragmented (experiment 2). We manipulated fragment length in each experiment except the last one, in which we presented only selected points (experiment 3). While fragmented versions were on average more identifiable when straight fragments were shown, certain objects were more identifiable when the curved segments or the angles were shown. A tentative explanation of these results is presented in terms of an advantage for straight segments during grouping processes for outlines with high part salience, and an advantage for curved segments during matching processes for outlines with low part salience.  相似文献

Previous research has indicated that covariations between the global layout of search displays and target locations result in contextual cuing: the global context guides attention to probable target locations. The present experiments extend these findings by showing that local redundancies also facilitate visual search. Participants searched for randomly located targets in invariant homogenous displays, i.e., the global context provided information neither about the location nor about the identity of the target. The only redundancy referred to spatial relations between the targets and certain distractors: Two of the distractors were frequently presented next to the targets. In four of five experiments, targets with frequent flankers were detected faster than targets with rare flankers. The data suggest that this local contextual cuing does not depend on awareness of the redundant local topography but needs the redundantly related stimuli to be attended to.  相似文献
