Dissociation is typically defined as the lack of normal integration of thoughts, feelings, and experiences into consciousness and memory. The present article critically evaluates the research literature on cognitive processes in dissociation. The authors' review indicates that dissociation is characterized by subtle deficits in neuropsychological performance (e.g., heightened distractibility). Some of the cognitive phenomena (e.g., weakened cognitive inhibition) associated with dissociation appear to be dependent on the emotional or attentional context. Contrary to a widespread assumption in the clinical literature, dissociation does not appear to be related to avoidant information processing. Rather, it is associated with an enhanced propensity toward pseudo-memories, possibly mediated by heightened levels of interrogative suggestibility, fantasy proneness, and cognitive failures. Evidence for a link between dissociation and either memory fragmentation or early trauma based on objective measures is conspicuously lacking. The authors identify a variety of methodological issues and discrepancies that make it difficult to articulate a comprehensive framework for cognitive mechanisms in dissociation. The authors conclude with a discussion of research domains (e.g., sleep-related experiences, drug-related dissociation) that promise to advance our understanding of cognition and dissociation. 相似文献

In this study, we evaluated the sensitivity of a 5-min personal digital assistant-psychomotor vigilance test (PDA-PVT) to severe sleep loss. Twenty-one participants completed a 10-min PVT-192 and a 5-min PDA-PVT at two hourly intervals during 62 h of sustained wakefulness. For both tasks, response speed and number of lapses (RTs > 500) per minute significantly increased with increasing hours of wakefulness. Overall, standardized response speed scores on the 5-min PDA-PVT closely tracked those of the PVT-192; however, the PDA-PVT was generally associated with more lapses/minute. Closer inspection of the data indicated that when the level of sleep loss and fatigue became more severe (i.e., Day 3), the 5-min PDA-PVT was not quite as sensitive as the 10-min PVT-192 when 2- to 10-sec foreperiods were used for both. It is likely, however, that the observed differences between the two devices was due to differences in task length. Thus, the findings provide further evidence of the validity of the 5-min PDA-PVT as a substitute for the 10-min PVT-192, particularly in circumstances in which a shorter test is required and/or the PVT-192 is not as practical. 相似文献

This question—why did Bodhidharma come from the West?— is ubiquitous in Chinese Ch’an Buddhist literature. Though some see it as an arbitrary question intended merely as an opener to obscure puzzles, I think it represents a genuine intellectual puzzle: Why did Bodhidharma come from theWest—that is, fromIndia? Why couldn’tChina with its rich literary and philosophical tradition have given rise to Buddhism? We will approach that question, but I prefer to do so backwards. I want to ask instead, “why was it so fortuitous for the development of Buddhist philosophy that Bodhidharma wentEast? I will argue that by doing so he gave a trajectory to Buddhist thought about the mind and knowledge that allows certain issues that are obscure in Indo-Tibetan Buddhism, despite their centrality to the Buddhist critique of Indian orthodoxy, to come into sharper relief, and hence to complete a project begun, but not completable, in that Indo-European context. 相似文献

Culturally, America is well overdue for a Second Enlightenment, but since the dominant majority of its citizens are regrettably
both symbol-minded and star-craving mad, and since the mass media are generally inaccessible to us, the chance that contemporary
philosophers could contribute to such a thing, much less help instigate it, is near vanishingly small. As educators, in contrast,
we can perhaps make ourselves useful by beginning to clear the extensive muck out of at least some of our students’ minds.
In any event, the discipline of philosophy as such is in serious need of renewal, but that, should it unexpectedly happen,
will be matter of luck rather than a result of deliberate action. 相似文献

This research assessed factors that may affect men’s romantic relationships. One hundred men (50 heterosexual and 50 gay) in the Northeast US completed measures that assessed masculinity ideology, male identity, and relationship quality. We examined whether the quality of heterosexual men’s romantic relationships differ from that of romantic relationships among gay men, and whether masculinity ideology and male identity are related to the quality of heterosexual and same-sex romantic relationships. Results indicated no differences between heterosexual and gay men in the perceived quality of romantic relationships. However, in both gay and heterosexual men, traditional masculinity ideology and a male identity characterized by a lack of psychological relatedness to other men were associated with lower quality romantic relationships. 相似文献

We investigated changes in autobiographical belief and memory ratings for childhood events, after informing individuals that forgetting childhood events is common. Participants received false prevalence information (indicating that a particular childhood event occurred frequently in the population) plus a rationale normalizing the forgetting of childhood events; false prevalence information alone; or no manipulation, for one (Study 1) or two (Study 2) unlikely childhood events. Results demonstrated that combining prevalence information and the "forgetting rationale" substantially influenced autobiographical belief ratings, whereas prevalence information alone had no impact (Study 1) or a significantly lesser impact (Study 2) on belief ratings. Prevalence information consistently impacted plausibility ratings. No changes in memory ratings were observed. These results provide further support for a nested relationship between judgements of plausibility, belief, and memory in evaluating the occurrence of autobiographical events. Furthermore, the results suggest that some purported false memory phenomena may instead reflect the development of autobiographical false beliefs in the absence of memory. 相似文献

The relation of patients' treatment preferences to outcome in a randomized clinical trial 总被引:2,自引:0,他引:2

Randomization procedures are performed in order to maximize the internal validity of treatment outcome studies. Objections have been made that this practice undermines the external validity of these studies because it ignores patients' treatment preferences, thereby precluding the self-selection of treatment that can occur in the community. This study used data from a multisite, double-blind, randomized, placebo-controlled trial comparing antidepressant medication to cognitive therapy for moderately to severely depressed outpatients. It compared the treatment outcomes of patients who, via randomization, received their preferred treatment versus those who did not. Although the majority of patients stated a preference for one treatment over the other, there was no significant difference in the magnitude of reduction in symptoms of depression between those who received their treatment of choice versus those who did not. These results do not provide support for the claim that the external validity of randomized controlled trials suffers from this aspect of the randomization procedure. 相似文献

This study is the first to examine the latent structure of individual differences reflected in the Adult Attachment Interview (AAI; C. George, N. Kaplan, & M. Main, 1985), a commonly used and well-validated measure designed to assess an adult's current state of mind regarding childhood experiences with caregivers. P. E. Meehl's (1995) taxometric methods (i.e., MAXCOV-HITMAX) were applied to data from 504 AAIs. Analyses revealed that the variation underlying secure versus dismissing states of mind was more consistent with a dimensional than a taxonic model. (Taxometric analyses of preoccupation were indeterminate.) In addition, variation in secure adults' (n=278) reports about their early experiences revealed little evidence for qualitative groups of earned- and continuous-secures. Rather, the inferred life experiences of secure adults appeared to be distributed continuously. Findings are discussed in terms of their theoretical implications regarding the phenomenon of earned-security specifically and variation underlying secure and insecure states of mind more generally. The consequences of these analyses for AAI reliability training and coding are also explored. 相似文献

For several decades, obesity has been a major health concern within the general population of the United States as well as
within the unique military population. Unlike the civilian sector, military service requires individuals to meet weight and
body fat standards. In order to assist overweight military personnel return to standards, Tripler Army Medical Center initiated
the LE3AN Program. LE3AN is a one-week, day-treatment, cognitive-behavioral weight management program coupled with 12 months of weekly follow-up.
Baseline data was collected on 387 consecutive participants. Despite physical fitness training and required standards in each
military service, the average BMIs for men and women were in the obese range, with male participants’ BMIs significantly higher
than women’s (34.3 vs 31.9, p<.005). One year outcome data was collected from 167 participants, i.e. 43.2% of treatment initiators. Among participants
who completed treatment, men maintained a 6.56% loss of their initial weight while women maintained a 7.35% loss. Over a quarter,
26.6%, of those who started the program (but did not complete it) maintained at least a 5% weight loss at one year, while
61.6% of treatment completers maintained 5% weight losses.

The spatial working memory system constantly updates spatial representations and many studies have focused on the underlying
principles of the encoding and maintenance of visual information. Here we investigated the question of how the production
of actions influences spatial working memory. Participants were given a task that required concurrent maintenance of two spatial
arrays, one encoded by visual observation accompanied with pointing movements, the other by only visual observation. Across
two experiments, movement during encoding was found to facilitate recognition of spatial arrays in a load-dependent manner.
The results suggest an action-based encoding principle within the working memory system, and possible underlying action-related
mechanisms are discussed. 相似文献
