The ability to plan and search ahead is essential for problem solving in most situations in everyday life. To investigate the development of planning and related processes, a sample of four- and five-year-old children was examined in a variant of the Tower of London, a frequently used neuropsychological assessment tool of planning abilities. The applied problems either required searching ahead for optimal solution or were solvable by pure step-by-step forward processing. Furthermore, the ambiguity of subgoal ordering was varied.Results revealed an age-related effect of search depth: the four-year olds’ planning accuracy was particularly decreased in problems demanding search ahead, while five-year olds mastered both problem types equally well. Interestingly, this interaction between age and search depth could not be accounted for by measures of working memory and inhibition. Differential effects of age were also found for subgoal ordering with respect to initial planning and movement execution times. In sum, planning abilities showed considerable development during late kindergarten age that appeared to be specifically associated with the integration and back-validation of the anticipated consequences of internally modeled actions. The present study demonstrates that a careful consideration of problem structure may greatly enhance the insights gained from the application of a routinely used assessment tool, the Tower of London. This may be especially advantageous when addressing specific subpopulations such as children or clinical samples. 相似文献

Unwanted effects or even damage due to psychotherapy are largely neglected issues within psychotherapy research as compared to other fields. On the other hand, it is reasonable to assume that unwanted effects of a treatment which intends to influence patients into a positive direction are very likely. The rate of negative effects of psychotherapy (the deterioration effect according to Bergin) is consistently estimated to be 10% of all cases and shows this same rate in a variety of studies. This review highlights side effects of psychotherapy both on the part of the patients and of the therapists. It reports unwanted effects related to different psychotherapeutic methods, i.e. psychoanalysis, cognitive behaviour therapy, client-centered psychotherapy and – beyond these basic orientations – group psychotherapy. The paper also reports on negative effects of psychotherapy on an untreated partner. Finally, some proposals are given on how negative effects of psychotherapy could be diminished. The authors especially highlight the possibilities of changing the therapist, the treatment technique, or the theoretical treatment approach as a way to reduce negative effects. 相似文献

Many school teachers suffer from stress and burnout, and perfectionism is a personality characteristic that has been associated with increased stress, maladaptive coping, and burnout. Recent findings, however, show that perfectionism has both positive and negative facets. To investigate how these facets are related to stress, coping, and burnout in teachers, a sample of 118 secondary school teachers completed multidimensional measures of perfectionism, stress appraisals, coping styles, and burnout. Multiple regression analyses showed that striving for perfection was positively related to challenge appraisals and active coping and inversely to threat/loss appraisals, avoidant coping, and burnout whereas negative reactions to imperfection were positively related to threat/loss appraisals, avoidant coping, and burnout and inversely to challenge appraisals and active coping. Perceived pressure to be perfect showed differential relationships depending on the source of pressure: Whereas pressure from students was positively related to loss appraisals and pressure from students' parents was positively related to burnout, pressure from colleagues was inversely related to threat appraisals and burnout. The findings suggest that striving for perfection and perceived pressure from colleagues do not contribute to stress and burnout in teachers, whereas negative reactions to imperfection and perceived pressure from students and students' parents may be contributing factors. 相似文献

In the prisoner's dilemma, self-interest clashes with collective interest. The way players resolve this conflict affects how others view them. Cooperators are seen as more moral than defectors, and, when there is no information about the other player's choice, cooperators and defectors are seen as equally competent. However, players who are defected against are seen as less competent, especially if they themselves cooperated (Experiments 1 and 2). Similarly, cooperators see themselves as more moral, but not as less competent, than defectors do (Experiments 3). Independent of concerns about reputation and self-image maintenance, evidential reasoning contributes to cooperative behavior. Players who project their own attitudes onto others are more likely to cooperate (Experiments 3). Compared with classic game theory, a theory of reputational concerns and evidential reasoning is better equipped to explain empirical patterns of choice behavior in social dilemmas. 相似文献

Recent studies have revealed that robust and replicable affective priming of naming responses can be obtained when pictures are used as primes and targets. The aim of the present research was to examine the predictive validity of affective priming effects that are obtained with the picture-picture naming task. In two studies that were modeled after [Karpinski, A., & Hilton, J. L. (2001). Attitudes and the Implicit Association Test. Journal of Personality and Social Psychology, 81, 774-778], we observed that individual difference scores that are obtained with the naming task exhibit good predictive validity. Both practical and theoretical implications of this finding are discussed. 相似文献

The present study investigated if unconscious primes can be processed according to different stimulus-response (S-R) rules simultaneously. Participants performed two different S-R rules, such as judging a digit as smaller or larger than five and judging a letter as vowel or consonant. These S-R rules were administered in random order and announced by a previously presented cue. Each target stimulus was preceded by subliminal primes which afforded a different or an identical response according to either the currently irrelevant or currently relevant S-R rule. In three experiments, we consistently found priming effects according to currently irrelevant S-R rules, even when primes for the relevant and irrelevant S-R rules were presented simultaneously. Thus, unconscious stimuli have the power to activate responses according to currently required and currently not required S-R rules concurrently. The results are in line with response activation accounts of subliminal priming and suggest that at least two routes may gain access on response processes simultaneously. 相似文献

The aim of this paper is to define a notion of supervenience which can adequately describe the systematic dependence of extrinsic
as well as of intrinsic higher-level properties on base-level features. We argue that none of the standard notions of supervenience—the
concepts of weak, strong and global supervenience—fulfil this function. The concept of regional supervenience, which is purported to improve on the standard conceptions, turns out to be problematic as well. As a new approach, we develop
the notion of property-dependent supervenience. This notion is founded on a criterion of relevance adapting the supervenience base to the considered higher-level properties
in a specific way, such that only features which are relevant to the instantiation of the higher-level properties under consideration
are taken into account. 相似文献
