Psychotherapists should always continuously remind themselves what role they and/or representatives of their discipline played and still play in various political contexts. Under these aspects the following general categories can be suitable for orientation: 1) general political participation, 2) application of specific psychotherapeutic perspectives for understanding of cultural, social and political processes and 3) development of possible activity perspectives from a psychotherapeutic viewpoint. The psychotherapeutic view of social processes and the possible resulting activity perspectives are a consequence of observation of the interplay between exactly these social processes and their deposition in the individual. 相似文献

Numerous studies have indicated that maintaining a fear memory after retrieval requires de novo protein synthesis. However, no study to date has examined how the temporal dynamics of repeated retrieval events affect this protein synthesis requirement. The present study varied the timing of a second retrieval of an established auditory fear memory and followed this second retrieval with infusions of the protein synthesis inhibitor anisomycin (ANI) into the basolateral amygdala. Results indicated that the memory-impairing effects of ANI were not observed when the second retrieval occurred soon after the first (within 1 h), and that the inhibitor gradually regained effectiveness as the retrieval episodes were spaced further apart. Additionally, if the second of the closely timed retrievals was omitted prior to ANI infusions, long-term memory deficits were observed, suggesting that the altered effectiveness of ANI was due specifically to the second retrieval event. Further experiments revealed that the second retrieval was not associated with a change in Zif268 protein expression but did produce a rapid and persistent dephosphorylation of GluR1 receptors at Ser845, an AMPAR trafficking site known to regulate the stability of GluR2 lacking AMPARs, which have been shown to be important in memory updating. This suggests that the precise timing of multiple CS presentations during the reconsolidation window may affect the destabilization state of the memory trace. 相似文献

We investigate first several entropy concepts, from static to dynamic entropy. Dynamic entropy is introduced as a measure of predictability. Then the relation between entropy and information is studied. Following Wiener information is considered as a non‐physical quantity, not matter or energy. Information is understood as a binary relation between a sender and a receiver. We differentiate between bound and free information. Information can be created by selforganization, historically it is connected with the origin of life. The structure and predictability of informational strings is investigated. For example we study symbolic sequences generated by evolution, as e.g. texts. It is shown that several information carriers show criticality connected with the existence of long‐range correlations, long memory in time and historical behaviour (self‐tuned criticality). The higher order Shannon entropies and the conditional entropies (dynamical entropies and there limit) are calculated, characteristic scaling laws are found. 相似文献

ABSTRACTPrior research and theory has suggested that rumination plays a role in nonsuicidal self-injury (NSSI), and rumination increases recall of negative autobiographical information in dysphoric individuals. Across two studies, we investigated whether rumination (versus distraction) differentially influences the recall of emotional words among dysphoric persons with and without a history of NSSI. Participants encoded unpleasant, neutral, and pleasant words and then were randomly assigned to either focus on the meaning and consequences of their emotions (i.e. rumination) or unrelated thoughts (i.e. distraction) before they were asked to recall encoded words. Across the two studies, we did not find a significant effect of rumination on memory for emotional words among dysphoric people with (Studies 1 and 2) or without a history of NSSI (Study 1). We did find that people were more likely to remember neutral words as opposed to unpleasant or pleasant words across studies, regardless of rumination condition. Together, results from these two well-powered studies provide fairly compelling evidence that rumination after encoding has little to no effect on recall for emotional words in people elevated on symptoms of depression or with NSSI history. These findings can be used to refine theories of rumination and NSSI. 相似文献

Abstract Self-compassion refers to having an accepting and caring orientation towards oneself. Although self-compassion has been studied primarily in healthy populations, one particularly compelling clinical context in which to examine self-compassion is social anxiety disorder (SAD). SAD is characterized by high levels of negative self-criticism as well as an abiding concern about others’ evaluation of one's performance. In the present study, we tested the hypotheses that: (1) people with SAD would demonstrate less self-compassion than healthy controls (HCs), (2) self-compassion would relate to severity of social anxiety and fear of evaluation among people with SAD, and (3) age would be negatively correlated with self-compassion for people with SAD, but not for HC. As expected, people with SAD reported less self-compassion than HCs on the Self-Compassion Scale and its subscales. Within the SAD group, lesser self-compassion was not generally associated with severity of social anxiety, but it was associated with greater fear of both negative and positive evaluation. Age was negatively correlated with self-compassion for people with SAD, whereas age was positively correlated with self-compassion for HC. These findings suggest that self-compassion may be a particularly important target for assessment and treatment in persons with SAD. 相似文献

When an aspect of a visual image is altered, observers often fail to notice the change. Recent studies suggest that successful change detection requires the observer to attend to and effortfully encode the changing aspect between the images. In this study we addressed the question of whether individual characteristics of the observer, namely expertise in a domain, selectively influence the ability to detect changes in images from that domain. A total of 48 individuals, half of whom were experts in the sport of American football and half of whom were American football novices, were presented alternating sequences of football-related and unrelated images. Our results indicate that expertise in a specific domain increases observers' sensitivity to semantic changes of domain-related images. Implications for the development of diagnostic tools are briefly addressed. 相似文献

In two experiments coupling between dorsal attentional selection for action and ventral attentional selection for perception during preparation of prehension movements was examined. In a dual-task paradigm subjects had to grasp an X-shaped object with either the left or the right hand's thumb and index finger. Simultaneously a discrimination task was used to measure visual attention prior to the execution of the prehension movements: Mask items transiently changed into distractors or discrimination targets. There was exactly one discrimination target per trial, which appeared at one of the four branch ends of the object. In Experiment 1 target position varied randomly while in Experiment 2 it was constant and known to subjects in each block of trials. In both experiments discrimination performance was significantly better for discrimination target positions at to-be-grasped branch ends than for not-to-be-grasped branch ends. We conclude that during preparation of prehension movements visual attention is largely confined to those parts of an object that will be grasped. 相似文献

This study explored the experiences of young adult women (n = 11) who grew up with emotionally absent fathers. The women (White: Afrikaans) were between the ages of 20 and 31 (5 were married, 1 was engaged, 1 was in a relationship, and 4 were single). The participants completed in-depth interviews regarding their retrospective perceptions of emotionally absent father experiences and the related effects on them. Data were thematically analyzed. Findings indicated that the participants experienced difficulty in sharing emotions with their fathers and fathers did not show affection or express their love. The participants perceived their fathers to have shown no interest, approval or acknowledgement of them, and viewed them as untrustworthy. They also believed that relationship qualities with their fathers influenced how they related to men in general. Father emotional absence negatively impacts on daughter's emotional well-being. 相似文献

Temporal and spatial coupling of point of gaze (PG) and movements of the finger, elbow, and shoulder during a speeded aiming task were examined. Ten participants completed 40-cm aiming movements with the right arm, in a situation that allowed free movement of the eyes, head, arm, and trunk. On the majority of trials, a large initial saccade undershot the target slightly, and 1 or more smaller corrective saccades brought the eyes to the target position. The finger, elbow, and shoulder exhibited a similar pattern of undershooting their final positions, followed by small corrective movements. Eye movements usually preceded limb movements, and the eyes always arrived at the target well in advance of the finger. There was a clear temporal coupling between primary saccade completion and peak acceleration of the finger, elbow, and shoulder. The initiation of limb-segment movement usually occurred in a proximal-to-distal pattern. Increased variability in elbow and shoulder position as the movement progressed may have served to reduce variability in finger position. The spatial-temporal coupling of PG with the 3 limb segments was optimal for the pick up of visual information about the position of the finger and the target late in the movement. 相似文献
