Anxiety and depression frequently co-occur and may share similar deficits in the processing of emotional stimuli. High anxiety is associated with a failure in the acquisition and extinction of fear conditioning. Despite the supposed common deficits, no research has been conducted on fear acquisition and extinction in depression. The main aim of the present study was to investigate and compare fear acquisition and extinction in anxiety- and depression-prone participants. Non-clinical anxious, depressive, anxious-depressive and control participants performed a fear discrimination task. During acquisition, the CS+ predicted an aversive event (unconditioned stimulus, US) and the CS? safety (no US). During extinction, the CS+ was no longer followed by the US, rendering it (temporarily) into a safety signal. On each CS participants rated their US expectancy; skin conductance responses (SCRs) were measured throughout. The expectancy scores indicated that high anxiety resulted in less safety learning during acquisition and extinction; no effect of depression was observed. SCRs showed that high-anxiety persons displayed less discrimination learning (CS+ minus CS?) during acquisition than low-anxiety persons. During extinction, high-depression persons demonstrated more discriminative SCR than low-depression persons. The observed discrepancies in response patterns of high-anxiety and -depression persons seem to indicate distinctive information processing of emotional stimuli. 相似文献

We studied the development of creative cognition in children ranging from nursery school to Grade 6 (4–12 yr old, N = 511), performing a problem generation task. The task involved inventing a novel item for a classical problem solving task they had completed beforehand: the Raven Progressive Matrices (RPM). This task and the generating task both comprise matrixes of components, to which a set of transformational relations are applied; only in the first case these are inferred to solve a puzzle, but in the second they are invented to create one. We analyzed the matrixes invented in the generation task and compared them to those of the original solving task. We observed that (a) both in solving and generation, the ability to combine more than 1 relation increased with grade level, (b) within all 8 grades, except Grades 3 and 6, performance was uncorrelated between both tasks, (c) relations that were applied in the generation task often did feature in the solving task, and (d) relations occurring in both tasks were applied with different frequencies. Overall, we conclude that standard problem solving ability is not a precondition for creative reasoning and that the comprehension of relations between components featured in solving task differs from that applied in generation. 相似文献

Concurrent feedback is defined as information about performance given to participants during the execution of an action. This article investigates whether concurrent feedback is beneficial or detrimental to the learning of an ecologically relevant task. Eighteen participants were asked to walk through a virtual corridor and they practiced over 1110 trials to adjust their walking speed so as to pass through sliding doors that opened and closed at a frequency of 1 Hz. Concurrent feedback informed them about the possible need to accelerate or decelerate. Performance of participants who received concurrent feedback on 66% of the practice trials (on average) did not differ significantly from performance of participants who did not receive concurrent feedback. Furthermore, participants of both of these groups significantly outperformed participants who received concurrent feedback on all practice trials. These results are discussed in relation to the perceptual-motor mechanisms that underlie the control of the action. Also discussed are implications for future research, including the use of self-controlled feedback and the use of multisensory training programs. 相似文献

Individuals make decisions under uncertainty every day. Decisions are based on incomplete information concerning the potential outcome or the predicted likelihood with which events occur. In addition, individuals' choices often deviate from the rational or mathematically objective solution. Accordingly, the dynamics of human decision making are difficult to capture using conventional, linear mathematical models. Here, we present data from a 2-choice task with variable risk between sure loss and risky loss to illustrate how a simple nonlinear dynamical system can be employed to capture the dynamics of human decision making under uncertainty (i.e., multistability, bifurcations). We test the feasibility of this model quantitatively and demonstrate how the model can account for up to 86% of the observed choice behavior. The implications of using dynamical models for explaining the nonlinear complexities of human decision making are discussed as well as the degree to which the theory of nonlinear dynamical systems might offer an alternative framework for understanding human decision making processes. 相似文献

The model of commitment presented in the present report postulates personality to be the crucial element in the development and maintenance of commitment to the profession of art. The objectives of the research reported here were to (a) demonstrate the typicality of the artist personality and (b) identify the traits which characterize committed and uncommitted artists. Three groups of artists were compared: mature established artists described as committed over a lifetime, committed art students, and uncommitted art students. The instrument used to evaluate personality was the Adjective Check List (ACL; Gough 8c Heilbrun, 1983). Both committed and uncommitted artists presented a typical personality structure; but in contrast to the committed, the uncommitted were characterized by low self‐esteem, a negative self‐image, impaired motivation, low staying power, and an inability to find a clear direction. Both art students and mature artists agreed about the order of importance of 11 factors considered to be determinants of committment. They both placed particular emphasis on autonomy, possibility to experiment, ease of inspiration, and early identification with the profession. 相似文献

The purpose of this study was to examine the relationships of perceived motivational climate to cohesion and collective efficacy in elite female teams. A total of 124 basketball and handball athletes completed two season measures (T1, T2). Relationships were examined at an individual level both statically and across time. Canonical correlations revealed that a combination of high perceptions of an ego-involving but low perceptions of a task-involving climate were associated with low perceptions of task cohesion at Time 1. High perceptions of a task-involving but low perceptions of an ego-involving climate were associated with higher perceptions of task cohesion and collective efficacy at Time 2. Moreover, low perceptions of an ego-involving and moderately low perceptions of a task-involving climate were associated with high perceptions of social cohesion at Time 2. Regression analyses including autoregressive influence indicated that a task-involving climate positively predicted variance in T2 group integration-task and collective efficacy after controlling for T1 scores. In contrast, an ego-involving climate negatively predicted changes in T2 athletes’ perceptions of social cohesion (individual attractions to the group-social [ATG-S], group integration-social [GI-S]) and group integration-task [GI-T] after controlling for T1 scores. Theoretical and practical implications are discussed. 相似文献

The purpose of this study was to investigate the relationship between psychological correlates and flow in tennis competition. Using a cross-sectional design, the sample of 261 junior tennis athletes showed moderate-to-strong correlations between flow (dispositional and state) and confidence (r disp = .59; r state = .35), imagery use (r disp = .58; r state = .32), and action control (r disp = .41; r state = .40), whereas absorption was orthogonal to flow. Commonality analysis revealed that imagery and confidence accounted for 34.2% of the variance in dispositional flow. The results are discussed for the development of intervention studies in order to enhance flow in competition. 相似文献

In this paper, a historical story is unfolded that illuminates crucial and tragic elements of both Hungarian history and the particular history of Hungarian psychoanalytic culture, institutes, and individuals. The paper follows a set of tragic persecutions of Hungarian analysts, first those leading up to the Second World War, the Holocaust, and then during postwar period of Stalinism and the Cold War. This paper opens a story and a historical record of courage, betrayal, international aid, despair, and resilience. The paper also sets this story in the context of the striking qualities of Hungarian psychoanalysis, beginning with Ferenczi. It is a tragic moment that a psychoanalytic movement, broadly interdisciplinary and linked to powerful forces of creativity and invention in many facets of theory of psychoanalysis and Hungarian culture, somehow surviving Nazism and Holocaust, finally became the victim of the Stalinist regime. The paper gives answers to the questions why and how psychoanalysis could be an enemy of the Stalinist dictatorship in Hungary. The paper charts the vitality and scope of psychoanalysis in Hungary and the terrible assaults that individuals and theories and institutions suffered over half a century. 相似文献

The ethical conduct of research rests largely on researchers, and as such, an understanding of how they perceive and enact their role in research is paramount. However, the literature around ethics and research mostly focuses on researchers’ perception of Research Ethics Boards (REB; also known as Institutional Review Boards) roles and functions. To fill that gap, we analyzed the perceptions of researchers, REB members, and influential parties (n = 40) about researchers’ role in the ethical conduct of research through discourse analysis. Three discourses emerged: researchers as reflective practitioners, protectors of participants, and technicians. Understanding the commonalities and differences among the discourses may foster a shared and compelling institutional research culture. 相似文献

Mourners often rely on faith following loss, but not all find spirituality comforting. Some grievers engage in negative religious coping (NRC), signaled by behaviors and thoughts such as anger toward God or their faith community, feeling spiritually abandoned, or questioning God's power. Our longitudinal study of 46 African American homicide survivors explored the relation of both positive religious coping (PRC) and NRC to complicated grief (CG) and investigated whether religious coping more strongly predicted psychological distress or vice versa. Results indicated that NRC was associated with CG, whereas PRC was substantially unrelated to bereavement outcome. Significantly, CG prospectively predicted high levels of spiritual struggle 6 months later, both in terms of CG and NRC composite scores and at the individual-item level. Clinical implications regarding spiritually sensitive interventions are noted. 相似文献
