Threat in dreams: an adaptation? 总被引:2,自引:2,他引:0
Revonsuo's influential Threat Simulation Theory (TST) predicts that people exposed to survival threats will have more threat dreams, and evince enhanced responses to dream threats, compared to those living in relatively safe conditions. Participants in a high crime area (South Africa: n=208) differed significantly from participants in a low crime area (Wales, UK: n=116) in having greater recent exposure to a life-threatening event (chi([1,N=186])(2)=14.84, p<.00012). Contrary to TST's predictions, the SA participants reported significantly fewer threat dreams (chi([1,N=287])(2)=6.11, p<.0134), and did not differ from the Welsh participants in responses to dream threats (Fisher's Exact test, p=.2478). Overall, the incidence of threat in dreams was extremely low-less than 20% of dreams featured realistic survival threats. Escape from dream threats occurred in less than 2% of dreams. We conclude that this evidence contradicts key aspects of TST. 相似文献

Malcolm-Smith, Solms, Turnbull and Tredoux [Malcolm-Smith, S., Solms, M., Turnbull, O., & Tredoux, C. (2008). Threat in dreams: An adaptation? Consciousness and Cognition, 17, 1281–1291.] conducted a rigorous study that sampled two populations differentially exposed to threat in real life, and found that critical predictions from the Threat Simulation Theory of dreams [Revonsuo, A. (2000a). The reinterpretation of dreams: An evolutionary hypothesis of the function of dreaming. Behavioral and Brain Sciences, 23, 877-901.; Revonsuo, A. (2000b). Did ancestral humans dream for their lives? Behavioral and Brain Sciences, 23, 1063–1082.] were not supported. Specifically, we found no evidence of increased realistic threats to physical survival or enhanced threat avoidance in the dreams of those from the exposed population. Revonsuo and Valli’s [Revonsuo, A., & Valli, K. (2008). How to test the threat simulation theory. Consciousness and Cognition, 17, 1292-1296.] commentary on our study argues that the methods we used are so flawed as to render the results meaningless. In this response article, we address the criticisms raised in their commentary. 相似文献

In this study, we examined whether good auditory and good visual temporal processors were better than their poor counterparts on certain reading measures. Various visual and auditory temporal tasks were administered to 105 undergraduates. They read some phonologically regular pseudowords and irregular words that were presented sequentially in the same ("word" condition) and in different ("line" condition) locations. Results indicated that auditory temporal acuity was more relevant to reading, whereas visual temporal acuity was more relevant to spelling. Good auditory temporal processors did not have the advantage in processing pseudowords, even though pseudoword reading correlated significantly with auditory temporal processing. These results suggested that some higher cognitive or phonological processes mediated the relationship between auditory temporal processing and pseudoword reading. Good visual temporal processors did not have the advantage in processing irregular words. They also did not process the line condition more accurately than the word condition. The discrepancy might be attributed to the use of normal adults and the unnatural reading situation that did not fully capture the function of the visual temporal processes. The distributions of auditory and visual temporal processing abilities were co-occurring to some degree, but they maintained considerable independence. There was also a lack of a relationship between the type and severity of reading deficits and the type and number of temporal deficits. 相似文献

This study examined the relative involvement of rapid auditory and visual temporal resolution mechanisms in the reading of phonologically regular pseudowords and English irregular words presented both in isolation and in contiguity as a series of six words. Seventy-nine undergraduates participated in a range of reading, visual temporal, and auditory temporal tasks. The correlation analyses suggested a general timing mechanism across modalities. There were more significant correlations between the visual temporal measures and irregular word reading and between the auditory measures and pseudoword reading. Auditory gap detection predicted pseudoword reading accuracies. The low temporal frequency flicker contrast sensitivity measure predicted the accuracies of isolated irregular words and pseudowords presented in contiguity. However, when a combined speed-accuracy score was used, visible persistence at both low and high spatial frequencies and auditory gap detection were active in the reading of pseudowords presented in contiguity. Sensory processing skills in both visual and auditory modalities accounted for some of the variance in the reading performance of normal undergraduates, not just reading-impaired students. 相似文献

The multiple-baseline across responses design was used to assess the effectiveness of a belief-modification treatment package to alter the intensity of three delusional beliefs of a chronically mentally ill inpatient. Results revealed reductions in belief intensity to zero levels for all three beliefs. Generalization effects were obtained for an individualized interview and psychiatric rating scale. These results were maintained through a 6-month follow-up period. 相似文献

A notion as pervasive and much-used as 'enterprise' will, inevitably, have done harm as well as good. The core concepts in the notion are explored, and examples are examined of how they have been put to teachers and counsellors in careers education and guidance work. While the libertarian text of education for enterprise may be unacceptable to many, the struggle to deal with it has forced a realisation of its more valuable subtext. This illustrates how 'education for enterprise', or any other change, cannot be implemented without paying attention to the organisation and management of change as well as to its intended outcomes, and how this process may have its own sometimes more beneficial effects. 相似文献

The self-injurious behavior (SIB) of a blind, profoundly retarded male was observed within a field setting as multiple forms of punishment were applied. The effects of hair-tug punishment were first systematically examined, then hair-tug and electric shock punishment were administered in varing ratios (of punishment deliveries per SIB response) supplemented by continuous restraint contingencies and made contingent on recurrent antecedents of SIB cycles. Treatments were applied over six months of consecutive daily sessions ranging from 30 min to 8 hr duration. Posttreatment followup observations were taken 12, 24, and 34 months after treatment. Partial suppression was produced as a direct function of hair-tug punishment in the initial phase. A generally progressive decrement was produced on already lowered SIB rates with the succeeding components of the treatment package. Extended periods of total SIB suppression occurred as punishment was rendered contingent on antecedent components of each SIB response cycle. Followup observations of nearly 3 yr duration indicated total suppression generalized over all settings in which the subject functioned. The findings were related to the contrasting limits prevailing in most reports of punishment-based SIB suppression. 相似文献

The present study tested derivations from social learning theory on the disinhibition of aggression through processes that weaken self-deterring consequences to injurious conduct. Subjects were provided with opportunities to behave punitively under diffused or personalized responsibility toward groups that were characterized in either humanized, neutral, or dehumanized terms. Both dehumanization and lessened personal responsibility enhanced aggressiveness, with dehumanization serving as the more potent disinhibitor. Escalation of aggression under conditions of dehumanization was especially marked when punitiveness was dysfunctional in effecting desired changes. The uniformly low level of aggression directed toward humanized groups, regardless of variations in responsibility and instrumentality of the conduct, attested to the power of humanization to counteract punitiveness. Results of supplementary measures are consistent with the postulated relationship between self-disinhibiting processes and punitiveness. Dehumanization fostered self-absolving justifications that were in turn associated with increased punitiveness. Findings on the internal concomitants of behavior performed under different levels of responsibility suggest that reducing personal responsibility heightens aggressiveness more through social than personal sources of disinhibition. 相似文献

An investigation of sex differences in same-sex friendships was conducted in terms of the intersection and social penetration model of relationship development, and Bem's theory of sex role orientation. The results indicated that there were significant sex differences in the nature of the same-sex friendships studied. In the terminology of Levinger's (Toward the Analysis of Close Relationships, Journal of Experimental Psychology, 1980, 16, 510–544) intersection model, female same-sex friendships indicated greater involvement. In the terminology of Altman and Taylor's (Social Penetration: The Development of Interpersonal Relationships, New York: Holt, Rinehart & Winston, 1973) social penetration model, female friendships demonstrated greater depth. Overall, the female friendships were of longer duration than those of the males. The differences in involvement and depth were found within each designated level of friendship (causal, good, and close). However, the difference in involvement was moderated by the sex role orientation of the participants, in that the sex difference was greater between sex-typed individuals than between androgynous individuals. An examination of questionnaire subscale intercorrelations indicated that females tended to seek friends to whom they could relate in many different areas, while males tended to develop different relationships to meet different needs. 相似文献

Does grief progress through stages? Do all people go through the same experiences? What health considerations are present in each grief experience? Does religion help? Although all people do not go through the same stages nor do they progress at the same rate, many people do go through such stages as the following: shock, lamentations, withdrawal, frustration, panic, depression, detachment, adaptation, reinvestment, and growth. There is often an interaction in these stages between stress and physical symptoms, and many grievers report that religion gives a good philosophical arean in which to work through their grief. 相似文献
