Cognitive functioning in delusions: a longitudinal analysis 总被引:2,自引:0,他引:2
BACKGROUND: This study explored the longitudinal course of the relationship between delusions and different aspects of cognitive functioning. METHODS: Deluded patients were compared to psychiatric and non-clinical controls on three tasks: negative priming, a probabilistic judgement task (the 'beads' task), and the pragmatic inference task (PIT). All groups were tested at two time points, once when actively symptomatic, and once when in remission. RESULTS: Deluded individuals exhibited a 'jump-to-conclusions' (JTC) reasoning bias: i.e., they made decisions on the basis of limited evidence and were more likely to revise their estimates when faced with disconfirmatory evidence. This JTC bias remained stable over time, although probability judgments seemed to normalise in remission. No deficits in cognitive inhibition were found on negative priming. The deluded group displayed an excessive self-focus on the PIT at both time points, but did not show a depressive attributional style. Only a small sub-sample, characterised by the "bad-me" type of paranoia [Trower & Chadwick, 1995 Clinical Psychology: Science and Practice, 2, 263-278.], demonstrated depressive schemas when symptomatic, but no longer did so when remitted. Few relationships were found between tasks, suggesting that different areas of functioning are relatively independent. The only measures associated with delusion symptom scores were from the 'beads' task. CONCLUSIONS: Overall these findings suggest that the JTC bias is a stable factor associated with delusional thinking, while the depressive attributional style characteristic of a small sub-sample of paranoid patients fluctuates with delusional course. 相似文献

This study investigated the role of need for closure (NFC) and anxiety in delusions. The Need For Closure Scale (NFCS) and measures of trait and state anxiety were administered to an early psychosis group with current delusions, a clinical (generalised anxiety disorder--GAD) control group and a non-clinical control group. The battery of questionnaires was repeated at follow-up one year later. The NFCS did not meet criteria for a unidimensional scale and two sub-scales were removed from all further analyses. At baseline the deluded and GAD groups scored significantly higher on the reduced NFCS (NFCS-R) than the control group. Trait anxiety was related to NFCS-R in the GAD and non-clinical control groups, but not in the deluded group. At follow-up all groups scored significantly lower on the NFCS-R, perhaps suggesting a practice effect, although the two clinical groups continued to have higher scores than the non-clinical control group. The recovered and non-recovered deluded groups did not differ on the NFCS-R one year later, unlike in the GAD group where recovered participants had significantly lower scores than the non-recovered. Change scores on the NFCS-R and trait anxiety were correlated at trend level in the GAD and non-clinical control groups, but not in the deluded group. These findings suggest that whilst NFC and trait anxiety are related in non-psychotic groups, NFC may be implicated in the formation of delusions, independently of anxiety, in psychotic individuals. 相似文献

A procedure for subtyping individuals who stutter and its relationship to treatment outcome is explored. Twenty-five adult participants of the Comprehensive Stuttering Program (CSP) were classified according to: (1) stuttering severity and (2) severity of negative emotions and cognitions associated with their speech problem. Speech characteristics (percentage of stuttered syllables, distorted speech score, and the number of correctly produced syllables on a diadochokinesis task) and emotional/cognitive states (emotional reaction, speech satisfaction, and attitudes toward speaking) were assessed before and after treatment, and at a 1- and 2-year follow-up. The results showed that: (a) there was no relationship between stuttering severity and the severity of negative emotions and cognitions, (b) the severe stuttering group had the largest treatment gains but also the highest level of regression, and (c) at post-treatment and both follow-up assessments the differences on measures of emotions between the mild and severe emotional group had disappeared, chiefly due to a large decrease in the latter group's negative emotions and cognitions. Our findings show that, based on treatment gains, specific subgroups can be identified, each requiring different treatment approaches. This underlines the necessity of developing a better understanding of how various dimensions of stuttering relate to treatment outcome. Educational objectives: The reader will be able to: (1) describe why stuttering severity and negative emotions and cognitions that are related to stuttering should be investigated separately and (2) describe how treatment outcome relates to subtypes of persons who stutter. 相似文献

There is an anomaly in the hindsight bias literature with respect to hindsight effects obtained after self-relevant negative
event outcomes: Whereas some studies have reported reduced hindsight bias, others have shown increases. This article contrasts
two explanations for the anomaly. The first points to an influence of perceived control over the event outcome: In hindsight,
people decrease foreseeability (and hence, responsibility and blame) for controllable events, but they increase the perceived
inevitability of uncontrollable events for coping reasons. The second explanation, derived from a reconception of hindsight
bias in terms of separate components (Blank, Nestler, von Collani, & Fischer, 2008), traces the anomaly to differences in
the observed hindsight components: Hindsight decreases are to be expected for foreseeability, whereas increases are restricted
to the inevitability component. Our experiment (N=210) manipulated controllability and the hindsight component orthogonally and showed strong support for the component explanation,
but also some influence of perceived control. 相似文献

AbstractThe application of market and customer analysis to selling is discussed in this article. Four instruments were devised and used with three companies in order to improve the performance of their salespeople. While the needs of salespeople vary according to the company and the industry, these instruments can form the basis for organizing the activities of salespeople. 相似文献

Subtraction problems of the type M ? S = ? can be solved with various mental calculation strategies. We investigated fourth‐ to sixth‐graders' use of the subtraction by addition strategy, first by fitting regression models to the reaction times of 32 two‐digit subtractions. These models represented three different strategy use patterns: the use of direct subtraction, subtraction by addition, and switching between the two strategies based on the magnitude of the subtrahend. Additionally, we compared performance on problems presented in two presentation formats, i.e., a subtraction format (81 ? 37 = .) and an addition format (37 + . = 81). Both methods converged to the conclusion that children of all three grades switched between direct subtraction and subtraction by addition based on the combination of two features of the subtrahend: If the subtrahend was smaller than the difference, direct subtraction was the dominant strategy; if the subtrahend was larger than the difference, subtraction by addition was mainly used. However, this performance pattern was only observed when the numerical distance between subtrahend and difference was large. These findings indicate that theoretical models of children's strategy choices in subtraction should include the nature of the subtrahend as an important factor in strategy selection. 相似文献

Langdon Gilkey died on 19 November 2004. This article reviews his career and examines elements in his systematic theology such as: (1) fallenness in human nature; (2) the transcendence and graciousness of God; (3) the Neo-Orthodox agenda; (4) creation and the dialogue with science; and (5) inter-religious dialogue. Gilkey's theological method of responding to human experience with the Christian message through a process of interpreting symbols is critically evaluated. This article is simultaneously published in Dialog and Theology and Science. 相似文献
