We argue performance in the serial reaction time (SRT) task is associated with gradations of awareness that provide examples of fringe consciousness [Mangan, B. (1993b). Taking phenomenology seriously: the “fringe” and its implications for cognitive research. Consciousness and Cognition, 2, 89–108, Mangan, B. (2003). The conscious “fringe”: Bringing William James up to date. In B. J. Baars, W. P. Banks & J. B. Newman (Eds.), Essential sources in the scientific study of consciousness (pp. 741–759). Cambridge, MA: The MIT Press.], and address limitations of the traditional SRT procedure, including criticism of exclusion generation tasks. Two experiments are conducted with a modified SRT procedure where irrelevant stimulus attributes obscure the sequence rule. Our modified paradigm, which includes a novel exclusion task, makes it easier to demonstrate a previously controversial influence of response stimulus interval (RSI) on awareness. It also allows identification of participants showing fringe consciousness rather than explicit sequence knowledge, as reflected by dissociations between different awareness measures. The NEO-PI-R variable Openness to Feelings influenced the diversity of subjective feelings reported during two awareness measures, but not the degree of learning and awareness as previously found with traditional SRT tasks [Norman, E., Price, M. C., & Duff, S. C. (2006). Fringe consciousness in sequence learning: the influence of individual differences. Consciousness and Cognition, 15(4), 723–760.]. This suggests possible distinctions between two components of fringe consciousness. 相似文献

Identifying the risk factors for individual differences in age-related cognitive ability and decline is amongst the greatest
challenges facing the healthcare of older people. Cognitive impairment caused by “normal ageing” is a major contributor towards
overall cognitive deficit in the elderly and a process that exhibits substantial inter- and intra-individual differences.
Both cognitive ability and its decline with age are influenced by genetic variation that may act independently or via epistasis/gene-environment
interaction. Over the past fourteen years genetic research has aimed to identify the polymorphisms responsible for high cognitive
functioning and successful cognitive ageing. Unfortunately, during this period a bewildering array of contrasting reports
have appeared in the literature that have implicated over 50 genes with effect sizes ranging from 0.1 to 21%. This review
will provide a comprehensive account of the studies performed on cognitively healthy individuals, from the first study conducted
in 1995 to present. Based on current knowledge the strong and weak methodologies will be identified and suggestions for future
study design will be presented. 相似文献

Neurophysiological and behavioral evidence suggests that the prefrontal cortex (PFC) may be sexually differentiated in nonhuman primates. The present study examined whether there are sex differences in working memory in humans that might reflect sexual differentiation of human PFC. Male and female undergraduates were administered a novel multitrial spatial working memory task (SPWM) and a verbal working memory task. In three experiments, females committed significantly fewer working memory errors and took significantly less time to reach criterion than males on the SPWM task. The female advantage was not accounted for by differences in general intellectual ability, attention, perceptual speed, incidental memory, or speed of verbal access. In Study 3, a sex difference was also observed on a measure of verbal working memory. The findings suggest that some prefrontal functions may be sexually differentiated in humans. 相似文献

Supplementary methods for the analysis of the Repeatable Battery for the Assessment of Neuropsychological Status are made available, including (a) quantifying the number of abnormally low Index scores and abnormally large differences exhibited by a case and accompanying this with estimates of the percentages of the normative population expected to exhibit at least this number of low scores and large differences, (b) estimating the overall abnormality of a case's Index score profile using the Mahalanobis Distance Index (MDI), (c) reporting confidence limits on differences between a case's Index scores, and (d) offering the option of applying a sequential Bonferroni correction when testing for reliable differences. With the exception of the MDI, all the methods can be obtained using the formulas and tables provided in this article. However, for the convenience of clinicians, and to reduce the possibility of clerical error, the methods have also been implemented in a computer program. More importantly, the program allows the methods to be applied when only a subset of the Indexes is available. The program can be downloaded from www.abdn.ac.uk/~psy086/dept/RBANS_Supplementary_Analysis.htm 相似文献

Background: Self-focused attention (SFA) and safety behaviors are two variables implicated in the maintenance of social anxiety disorder (SAD).Design: The present study examined SFA and safety behaviors across two therapies for SAD, cognitive behavioral group therapy (CBGT) and mindfulness and acceptance-based group therapy (MAGT).Method: Participants with symptoms meeting criteria for SAD (N?=?137) were randomly assigned to the 12-week-treatment groups (n?=?53 for each condition) or a waitlist control (n?=?31). Variables were assessed at baseline, midtreatment, posttreatment, and a 3-month follow-up.Results: Both treatment conditions reported significantly lower SFA and safety behaviors compared to control, but did not differ from one another at posttreatment. Mediation analyses supported the following models: (1) safety behaviors mediating the relationship between SFA and social anxiety, and (2) SFA mediating the relationship between safety behaviors and social anxiety. These models were supported for both treatment groups.Conclusions: Both treatments may have the potential to reduce the SFA and safety behaviors that serve to maintain SAD. 相似文献
