Applying the framework of ecological rationality, the authors studied the adaptivity of group decision making. In detail, they investigated whether groups apply decision strategies conditional on their composition in terms of task‐relevant features. The authors focused on the recognition heuristic, so the task‐relevant features were the validity of the group members' recognition and knowledge, which influenced the potential performance of group strategies. Forty‐three three‐member groups performed an inference task in which they had to infer which of two German companies had the higher market capitalization. Results based on the choice data support the hypothesis that groups adaptively apply the strategy that leads to the highest theoretically achievable performance. Time constraints had no effect on strategy use but did have an effect on the proportions of different types of arguments. Possible mechanisms underlying the adaptive use of recognition in group decision making are discussed. 相似文献

Diagnostic approaches in psychotherapy are accompanied by a continuous and unchanged discussion concerning fundamental questions. Because of its many functions diagnostics in psychotherapy has to take psychiatric, psychological, orientation-specific models and methods of assessment into consideration. Following the publication of the fifth edition of the diagnostic and statistical manual of mental disorders (DSM-5) the increasing danger of a further increase in the number of psychiatric disorders is evident. In this article the principles of current psychiatric diagnostics and psychodynamic psychotherapy are presented and discussed. Furthermore, the dangers associated with the increased medicalization and over-diagnosis are highlighted. Against this background consideration is given to the risks for patients and societal aspects. 相似文献

Skeptical hypotheses such as the brain-in-a-vat hypothesis provide extremely poor explanations for our sensory experiences. Because these scenarios accommodate virtually any possible set of evidence, the probability of any given set of evidence on the skeptical scenario is near zero; hence, on Bayesian grounds, the scenario is not well supported by the evidence. By contrast, serious theories make reasonably specific predictions about the evidence and are then well supported when these predictions are satisfied. 相似文献

The mental system of an individual usually generates a reality-model that includes a self-model and a world-model as fundamental
components. Exceptional experiences (ExE) can be classified as subjectively experienced anomalies in the self-model or the
world-model or in the relation of both. Empirical studies show significant correlations between specific patterns of ExE and
socially and clinically relevant variables. In order to examine the ontological status of anomalous phenomena a psychophysical
approach is presented in which the principle of complementarity is of fundamental importance. Applying a generalized quantum
theory to psychosocial and psychophysical systems, complementary aspects such as autonomy versus reliability or novelty versus
confirmation are identified as possible local and global variables. The findings indicate that entanglement correlations could
play a role in the occurrence of ExE and that specific psychological interventions can dissolve them. 相似文献

Previous research on sensorimotor synchronization has manipulated the somatosensory information received from the tapping
finger to investigate how feedback from an active effector affects temporal coordination. The current study explored the role
of feedback from passive body parts in the regulation of spatiotemporal motor control parameters by employing a task that
required finger tapping on one’s own skin at anatomical locations of varying tactile sensitivity. A motion capture system
recorded participants’ movements as they synchronized with an auditory pacing signal by tapping with the right index finger
on either their left index fingertip (Finger/Finger) or forearm (Finger/Forearm). Results indicated that tap timing was more
variable, and movement amplitude was larger and more variable, when tapping on the finger than when tapping on the less sensitive
forearm. Finger/Finger tapping may be impaired relative to Finger/Forearm tapping due to ambiguity arising through overlap
in neural activity associated with tactile feedback from the active and the passive limb in the former. To compensate, the
control system may strengthen the assignment of tap-related feedback to the active finger by generating correlated noise in
movement kinematics and tap dynamics. 相似文献

There is evidence that daily negative events at work enhance fatigue. In contrast, positive events may trigger processes that increase, but also processes that decrease, energetic resources. Accordingly, results regarding a main effect of positive events on fatigue have been mixed. However, a clearer pattern between positive events and fatigue can be expected under adverse circumstances (i.e., accumulation of negative events, high chronic stressors). Positive events may facilitate coping and accelerate recovery processes and, thus, reduce resource drain due to daily negative events and chronic stressors. Predicting fatigue in a diary study with 76 employees, we investigated interactions between daily positive events and (a) daily negative events and (b) chronic social stressors. Multilevel modeling revealed that negative but not positive events were associated with increased end-of-work fatigue. However, positive events interacted with negative events and with chronic social stressors. As expected, positive events were negatively associated with fatigue only on days with many negative events, but not so on days with few negative events. Analogously, positive events were negatively associated with fatigue only among employees with high, compared with low, chronic social stressors. We conclude that the beneficial short-term effects of positive events on energetic resources are largely confined to adverse circumstances. 相似文献

People often forget their long‐term strivings because their environment confronts them with attractive temptations. Previous research suggests that self‐control failures can be prevented by reminding people of their higher‐order goal. Therefore, we hypothesized that using implementation intentions as a tool to directly re‐activate people's higher‐order goal in tempting situations would effectively enhance self‐control. We tested this in the domain of dieting behavior. Results demonstrated that this specific planning strategy activated the dieting goal for unsuccessful dieters when exposed to tempting food cues (Study 1) and reduced their consumption of calorically dense food across 2 weeks (Study 2) compared to those in control conditions. This suggests that preparing people to think of their higher‐order goal when tempted can be used to protect ongoing goal striving. Appealing to higher‐order goals potentially makes implementation intentions flexible instruments of self‐regulation as this should trigger motivated behavior to reach goals and initiate various goal‐instrumental actions.

In this study, 6-month-olds’ perception of an object-related human grasping action was compared with their level of grasping performance using a within-participants design. In the action perception task, infants were presented with the video of an actor’s grasping movement toward an occluded target object. Subsequently, an expected and an unexpected final state of this grasping movement were presented simultaneously, and infants’ looking times were measured. In the action production task, infants were presented with three graspable objects. Infants’ grasping behavior was coded to be either palmar or thumb-opposite grasping. Results indicate that infants who were already able to perform a thumb-opposite grasp differentiated between the two final states in the action perception task by looking longer toward the unexpected final state. In contrast, infants who showed only palmar grasps looked equally long toward both final states. This finding supports the assumption that action perception and action control are already closely related in infants as young as 6 months. 相似文献
