Dissociation and dissociative disorders represent a heterogenous phenomenology of symptoms which are understood as a result of the disintegration of certain usually integrated functions of the psyche. Despite an ongoing debate among scientists about its causation the assumption of a trauma-related etiology is carried forward both in clinical and scientific contexts. Therapists often believe dissociation to constitute an infirm basis for psychotherapeutic treatments. Contrarily, research suggests several kinds of therapeutic interventions and combinations thereof in particular, to be effective in relieving patients even of complex dissociation if certain requirements are met. This review summarizes the historical and conceptual implications as well as recent developments in the concept, diagnosis and therapy of dissociation. 相似文献

As a rule, the discriminability of multiple symmetries from random patterns increases with the number of symmetry axes, but this number does not seem to be the only determinant. In particular, multiple symmetries with orthogonal axes seem better discriminable than multiple symmetries with nonorthogonal axes. In six experiments on imperfect two-fold symmetry, we investigated whether this is due to extra structure in the form of so-called correlation rectangles, which arise only in the case of orthogonal axes, or to the relative orientation of the axes as such. The results suggest that correlation rectangles are not perceptually relevant and that the percept of a multiple symmetry results from an orientation-dependent interaction between the constituent single symmetries. The results can be accounted for by a model involving the analysis of symmetry at all orientations, smoothing (averaging over neighboring orientations), and extraction of peaks. 相似文献

If priming effects serve an adaptive function, they have to be both robust and flexible. In four experiments, we demonstrated
regular evaluative-priming effects for relatively long stimulus-onset asynchronies, which can, however, be eliminated or reversed
strategically. When participants responded to both primes and targets, rather than only to targets, the standard congruity
effect disappeared. In Experiments 1a–1c, this result was regularly obtained, independently of the prime response (valence
or gender classification) and the response mode (pronunciation or keystroke). In Experiment 2, we showed that once the default
congruity effect was eliminated, strategic-priming effects reflected the statistical contingency between prime valence and
target valence. Positive contingencies produced congruity, whereas negative contingencies produced equally strong incongruity
effects. Altogether, these findings are consistent with an adaptive-cognitive perspective, which highlights the role of flexible
strategic processes in working memory as opposed to fixed structures in semantic long-term memory or in the sensorimotor system. 相似文献

The present study examined the role of controlled attention in age differences in event-based prospective memory performance across adolescence. The researchers tested whether presenting the prospective memory cue in or out of focal awareness of the ongoing task (resulting in low versus high demands for controlled attention, respectively) might affect age-related prospective memory performance. In total, 119 Chinese participants ages 13 to 20 took part in this study (60 adolescents: age M = 13.26 years, SD = 0.50; 23 boys; 59 young adults: age M = 19.70 years, SD = 0.87; 19 men). Findings demonstrated a significant interaction, F(1, 114) = 6.41, p < .05. No effect of age on prospective memory performance was revealed when a focal cue was used (F < 1), whereas there was a reliable age effect between adolescents and young adults when nonfocal prospective memory cues were presented, F(1, 59) = 16.13, p < .01. This pattern of results suggests that the interplay of both available resources of controlled attention and working memory, along with specific task demands, may contribute to possible age differences in prospective memory performance across adolescence. Results are discussed in the context of the multiprocess theory of prospective memory. 相似文献

Social change has accentuated various demands in people's work lives including, for instance, fears of being laid off, anticipated or experienced difficulties in finding a new and/or appropriate job or a lack of security in career planning. The present study on N = 1751 employed, short-term unemployed, and long-term (> 12 months) unemployed German adults examined the associations between the perceived accumulation of such demands and individuals' life satisfaction. Further, main and moderating effects of individuals' modes of dealing with these demands, that is, engagement and disengagement preferences based on Heckhausen and Schulz's (1995) life-span theory of control, were investigated. A higher load of demands was expected to be linked to lower life satisfaction irrespective of employment status. Positive main effects as well as buffering effects of engagement and disengagement, in contrast, were expected to differ depending on the particular employment situation. Multiple linear regressions including main and interaction effects set up as three-group comparison models showed that a high demand load was linked to lower life satisfaction in each of the three groups. Engagement was positively linked to life satisfaction in the case of employment, whereas in the transient stage of short-term unemployment, disengagement strengthened the negative link between demand load and life satisfaction. In the case of long-term unemployment, both modes of dealing with demands were positively related to life satisfaction. The positive effect of engagement, however, diminished as perceived demands increased, indicating that “over-engagement” may be counterproductive when faced with a high demand load. Consequences of our findings for potential interventions among unemployed people are discussed. 相似文献

Although fear of death features prominently in many historical and contemporary theories as a major motivational factor in religious belief, the empirical evidence available is ambivalent, and limited, we argue, by imprecise measures of belief and insufficient attention to the distinction between implicit and explicit aspects of cognition. The present research used both explicit (questionnaire) and implicit (single-target implicit association test; property verification) measurement techniques to examine how thoughts of death influence, specifically, belief in religious supernatural agents. When primed with death, participants explicitly defended their own religious worldview, such that self-described Christians were more confident that supernatural religious entities exist, while non-religious participants were more confident that they do not. However, when belief was measured implicitly, death priming increased all participants' beliefs in religious supernatural entities, regardless of their prior religious commitments. The results are interpreted in terms of a dual-process model of religious cognition, which can be used to resolve conflicting prior data, as well as to help explain the perplexing durability of religious belief. 相似文献

When participants are asked to respond in the same way to stimuli from different sources (e.g., auditory and visual), responses
are often observed to be substantially faster when both stimuli are presented simultaneously (redundancy gain). Different
models account for this effect, the two most important being race models and coactivation models. Redundancy gains consistent
with the race model have an upper limit, however, which is given by the well-known race model inequality (Miller, 1982). A number of statistical tests have been proposed for testing the race model inequality in single participants and groups
of participants. All of these tests use the race model as the null hypothesis, and rejection of the null hypothesis is considered
evidence in favor of coactivation. We introduce a statistical test in which the race model prediction is the alternative hypothesis.
This test controls the Type I error if a theory predicts that the race model prediction holds in a given experimental condition. 相似文献

The ability to anticipate future states of perceived actions is an important faculty for motor control and the generation of coordinated social interaction. Here, we studied whether the perception of a static posture of a complex movement automatically activates representations of future states of this particular movement event. We did this by using a priming paradigm with photographs of a high-jump movement. Participants judged whether a picture depicted a posture from the approach or flight phase of that movement. To evaluate expertise-dependent effects of priming, non-athletes and athletes were compared. Results revealed faster responding when prime and target pictures were assigned to the same motor response (response priming), and when the temporal order of prime and target matched the temporal order of the depicted postures in a real high jump (temporal-order priming). Whereas experts showed a temporal-order effect even within the same response category, such an effect occurred for novices only between response categories. A second experiment confirmed that these between-group differences are due to domain-specific motor expertise (i.e., high jump) rather than to general motor experiences. Altogether our results suggest that motor expertise results in a more fine-grained posture-based movement representation. 相似文献
