Ninety-nine undergraduate students retrieved three memories associated with each of the five emotional experiences: panic, trauma, worry, social anxiety, and feeling content. Subsequently, they answered 24 questions assessing properties of each memory, including the vividness and perceived accuracy of the memories and sensory, emotional, and anxiety-related experiences during retrieval. Memories were coded for affective tone and specificity. Results indicated that panic-related and trauma-related memories were rated similarly as content memories, but that they generally were associated with more imagery and emotional experiencing than worry-related or social anxiety-related memories. Participants experienced panic and worry symptoms to the greatest degree when they retrieved panic-related and trauma-related memories. All anxiety-related memories were characterized by more negative tone than content memories. Panic-related and trauma-related memories were more specific than worry-related, social anxiety-related, and content memories. These findings can explain partially why individuals with some, but not all, anxiety disorders experience enhanced memory for threatening material. 相似文献

We examine the time-course of semantic structure formation during real-time sentence comprehension. We do this through the lens of aspectual coercion, a semantic combinatorial operation that lacks morpho-syntactic reflections, yet is indispensable for sentence interpretation. We describe two experiments. Experiment 1 replicates the results of a previously published study (Piñango, Zurif, & Jackendoff, Journal of Psycholinguistic Research, 28(4), 395–414 1999) showing that the cost of implementing aspectual coercion is detectable as late as 250 ms after the operation is licensed. Experiment 2 expands the window of observation by revealing that the implementation of aspectual coercion is not detectable immediately upon its being licensed, that is, at the point at which the syntactic representation is assumed to be fully formed. These findings suggest a dissociation in the integration of information, in which semantic composition—even mandatory and automatic semantic composition—takes time to develop after it is syntactically licensed to do so.The research reported here was supported by NIH Grant DC 03660. 相似文献

The polyamines, spermine, spermidine, and putrescine, are a group of aliphatic amines that may act as physiological modulators of N-methyl-D-aspartate (NMDA) receptors. Although the modulatory role of polyamines in NMDA receptor function has long been known, the effects of polyamines on learning and memory only recently began to be unraveled. In the present study, we investigated the effect of bilateral infusions of spermidine (0.02-2 nmol), a polyamine agonist, into the CA1 region of the rat dorsal hippocampus on inhibitory avoidance learning 30 min pre-training, immediately post-training, 6 h post-training, or 10 min pre-test. Bilateral microinjections of 0.2 nmol spermidine prolonged step-down latencies compared to the respective control group when administered 30 min pre-training or immediately post-training. These results provide evidence that the modulatory effects of spermidine on the acquisition and/or early consolidation of memory of inhibitory avoidance tasks in the hippocampus occur within a limited time window. 相似文献

This paper examines some difficulties inherent in the process of integration of potentially divergent theoretical positions. It is noted that there is an increasing tendency toward integration of Jungian theory with various models from psychoanalysis and other scientific disciplines. This trend can be understood as relating to the larger post-modern current operating in the scientific and cultural communities. As an element of the Zeitgeist, theory integration can proceed with a lack of critical stance on the process itself. An argument is developed on theoretical grounds for urging caution in the implementation of theory integration. The integrative process is examined using dream material from D. W. Winnicott in conjunction with his review of Memories, Dreams, Reflections. Through this discussion, some implications are examined as to the viability of linking Jungian and developmental models. 相似文献

This study reports evidence that schizophrenia patients are significantly impaired in both spatial and object (shape) working memory. A 3-s delay between exposure and recall of targets was used and Bayesian item-response theory was applied to compensate for the tasks' differential difficulty while simultaneously taking account of missing data from participant attrition. Weaker evidence was found that in schizophrenia both domains are equally impaired on average, that spatial and object working memory appear to be more highly correlated with each other in the schizophrenia population than in the normal population, and that schizophrenia patients show greater variability in spatial than object working memory performance. 相似文献

Thirty years after fleeing from Poland to Denmark, 20 immigrants were enlisted in a study of bilingual autobiographical memory. Ten "early immigrators" averaged 24 years old at the time of immigration, and ten "late immigrators" averaged 34 years old at immigration. Although all 20 had spent 30 years in Denmark, early immigrators reported more current inner speech behaviours in Danish, whereas late immigrators showed more use of Polish. Both groups displayed proportionally more numerous autobiographical retrievals that were reported as coming to them internally in Polish (vs Danish) for the decades prior to immigration and more in Danish (vs Polish) after immigration. We propose a culture- and language-specific shaping of semantic and conceptual stores that underpins autobiographical and world knowledge. 相似文献

Our studies revealed two stable modes of perceptual organization, one based on attributes of auditory sensory elements and another based on attributes of patterned sensory variation composed by the aggregation of sensory elements. In a dual-task method, listeners attended concurrently to both aspects, component and pattern, of a sine wave analogue of a word. Organization of elements was indexed by several single-mode tests of auditory form perception to verify the perceptual segregation of either an individual formant of a synthetic word or a tonal component of a sinusoidal word analogue. Organization of patterned variation was indexed by a test of lexical identification. The results show the independence of the perception of auditory and phonetic form, which appear to be differently organized concurrent effects of the same acoustic cause. 相似文献

Social Identity, System Justification, and Social Dominance: Commentary on Reicher, Jost et al., and Sidanius et al. 总被引:1,自引:0,他引:1
The articles by Reicher (2004 ), Jost, Banaji, and Nosek (2004 ), and Sidanius, Pratto, van Laar, and Levin (2004 ) discuss the strengths and weaknesses of social identity theory ( Tajfel & Turner, 1979 ), system justification theory ( Jost & Banaji, 1994 ), and social dominance theory ( Sidanius, 1993 ). The latter two theories grew out of a critique of social identity theory, but this critique relates more to deficiencies in social identity research than to deficiencies in the theory itself. More balanced and comprehensive social identity research is required in order to allow a fair assessment of the theory's limitations. In addition, Reicher (2004 ) and Huddy (2004 ) are correct that only social identity theory offers the potential for explaining social change and social stability. 相似文献

Fifty veterans diagnosed with posttraumatic stress disorder (PTSD) each recalled four autobiographical memories: one from the 2 years before service, one non‐combat memory from the time in service, one from combat, and one from service that had often come as an intrusive memory. For each memory, they provided 21 ratings about reliving, belief, sensory properties, reexperiencing emotions, visceral emotional responses, fragmentation, and narrative coherence. We used these ratings to examine three claims about traumatic memories: a separation of cognitive and visceral aspects of emotion, an increased sense of reliving, and increased fragmentation. There was evidence for a partial separation of cognitive judgments of reexperiencing an emotion and reports of visceral symptoms of the emotion, with visceral symptoms correlating more consistently with scores on PTSD tests. Reliving, but not fragmentation of the memories, increased with increases in the trauma relatedness of the event and with increases in scores on standardized tests of PTSD severity.
