A hallmark feature of episodic memory is that of “mental time travel,” whereby an individual feels they have returned to a prior moment in time. Cognitive and behavioral neuroscience methods have revealed a neurobiological counterpart: Successful retrieval often is associated with reactivation of a prior brain state. We review the emerging literature on memory reactivation and recapitulation, and we describe evidence for the effects of emotion on these processes. Based on this review, we propose a new model: Negative Emotional Valence Enhances Recapitulation (NEVER). This model diverges from existing models of emotional memory in three key ways. First, it underscores the effects of emotion during retrieval. Second, it stresses the importance of sensory processing to emotional memory. Third, it emphasizes how emotional valence – whether an event is negative or positive – affects the way that information is remembered. The model specifically proposes that, as compared to positive events, negative events both trigger increased encoding of sensory detail and elicit a closer resemblance between the sensory encoding signature and the sensory retrieval signature. The model also proposes that negative valence enhances the reactivation and storage of sensory details over offline periods, leading to a greater divergence between the sensory recapitulation of negative and positive memories over time. Importantly, the model proposes that these valence-based differences occur even when events are equated for arousal, thus rendering an exclusively arousal-based theory of emotional memory insufficient. We conclude by discussing implications of the model and suggesting directions for future research to test the tenets of the model. 相似文献

A bidirectional relationship between sleep and anxiety is well-established whereby difficulties in one domain predict problems in the other. Interventions for childhood sleep-related problems also share considerable overlap with interventions for anxiety. Although anxious youth report high rates of sleep-related problems, it is relatively unknown whether anxiety-focused interventions for children produce improvements in sleep-related problems. The current study included N = 25 youth ages 7–16 (13 female; mean age 9.92 years ± 2.6) who participated in an early intervention program for anxiety as part of the Arizona Anxiety Resilience Building Project. Child and parent measures of sleep and anxiety symptoms were examined before and after the 12-week cognitive-behavioral intervention program. Statistically significant decreases in total sleep-related problems, bedtime resistance, sleep anxiety, and pre-sleep arousal were observed at post-intervention, though clinically meaningful change was apparent in only a small portion of the sample. Results suggest that purely anxiety-focused interventions may be useful for reducing certain types of sleep-related problems in anxious children, specifically those that occur during the bedtime/pre-sleep period. However, a lack of clinically meaningful change, in addition to post-intervention sleep-related problem scores above the clinical cut-off in a large proportion of the sample, suggest that the sleep-related problems of anxious youth may require direct attention as part of treatment. 相似文献

We compared the ability of three different contextual models of lexical semantic memory (BEAGLE, Latent Semantic Analysis, and the Topic model) and of a simple associative model (POC) to predict the properties of semantic networks derived from word association norms. None of the semantic models were able to accurately predict all of the network properties. All three contextual models over‐predicted clustering in the norms, whereas the associative model under‐predicted clustering. Only a hybrid model that assumed that some of the responses were based on a contextual model and others on an associative network (POC) successfully predicted all of the network properties and predicted a word's top five associates as well as or better than the better of the two constituent models. The results suggest that participants switch between a contextual representation and an associative network when generating free associations. We discuss the role that each of these representations may play in lexical semantic memory. Concordant with recent multicomponent theories of semantic memory, the associative network may encode coordinate relations between concepts (e.g., the relation between pea and bean, or between sparrow and robin), and contextual representations may be used to process information about more abstract concepts. 相似文献

DEVELOPMENT AND PSYCHOMETRIC EVALUATION OF THE INTERPERSONAL SEXUAL OBJECTIFICATION SCALE 总被引:1,自引:1,他引:0

This study reports on the development and psychometric evaluation of the Interpersonal Sexual Objectification Scale (ISOS). Data from 576 college women were collected in three studies. Exploratory factor analysis uncovered two factors: Body Evaluation and Unwanted Explicit Sexual Advances; confirmatory factor analysis supported this factor structure. ISOS scores were internally consistent and stable over a 3-week period. Supporting its construct validity, ISOS scores were (a) strongly related to sexist degradation; (b) slightly to moderately related to other sexist events, self-objectification (i.e., body surveillance and internalization of the thin-ideal), and body shame; and (c) unrelated to socially desirable responding. The relationship between ISOS scores and body shame was fully mediated by self-objectification, providing additional evidence for its construct validity. Furthermore, the ISOS garnered incremental validity, as it predicted self-objectification above and beyond the variance accounted for by sexist events. 相似文献
