This article reports the development of a protocol for the therapeutic application of "attention control" for chronic pain. Attention control is the limitation of the impact of pain by switching or retunning attention. An expert systems approach was used to develop the protocol. In the first stage an extensive literature search retrieved published and unpublished accounts of attention control strategies and a draft treatment manual was prepared. In the second stage 6 experts were recruited and they independently read and reviewed the draft manual. They were interviewed using a semi-structured protocol to elicit their views on the draft manual. The manual was then revised to accommodate the information and expertise. In addition to providing expert opinion on the manual the experts also raised issues about the process of change in psychological treatment for chronic pain. These issues were organized into a process model of change in chronic pain. 相似文献

Contour grouping inside and outside of facial contexts 总被引:1,自引:0,他引:1
We examine how contours group in isolation compared with when they are embedded in face-like contexts. As previously shown, contours that seem to group by phenomenological observation also show powerful effects on task performance: with contours that group, selective attention to one while ignoring another is poor (as indexed by Garner Interference (GI), but not Stroop Interference), whereas divided attention across contours is good. With contours that do not group, however, the reverse happens. Here we test pairs of curved lines (parentheses) displayed either in isolation or within contexts including cartoon faces, where these curves may serve as mouths or eyebrows. The results with isolated contours replicate previous findings of poor selective attention, but within face-like contexts the same contours showed nearly perfect selective attention (i.e., zero GI). Thus, contour grouping was weaker inside than outside of faces, a finding that contrasts with the widely-held belief that faces are processed configurally, not by local features. 相似文献

This article examines the interpersonal problems of 42 persons referred for brief group treatment at a community mental health center. Measures of symptom severity, self-esteem, and interpersonal problems were administered pre- and posttreatment. Study participants' scores were analyzed to determine possible differences in the interpersonal problems experienced by those diagnosed with personality disorders and those without them. Results revealed that both groups improved significantly on the overall measure of symptom severity. Findings further revealed that self-esteem improved significantly more for those diagnosed with personality disorders. Analysis of interpersonal problems scores revealed differences between the two groups in the areas of support and involvement prior to treatment, but not after. Possible explanations for these differences and implications for treatment are discussed. 相似文献

Lilienfeld, Wood, and Garb (2000) published a largely negative critique of the validity and reliability of projective methods, concentrating on the Comprehensive System for the Rorschach (Exner, 1993), 3 systems for coding the Thematic Apperception Test (TAT; Murray, 1943) cards, and human figure drawings. This article is an effort to document and correct what I perceive as errors of omission and commission in the Lilienfeld et al. article. When projective measures are viewed in the light of these corrections, the evidence for the validity and clinical usefulness of the Rorschach and TAT methods is more robust than Lilienfeld et al. represented. 相似文献

Although many neuroimaging studies of visual mental imagery have revealed activation in early visual cortex (Areas 17 or 18), many others have not. The authors review this literature and compare how well 3 models explain the disparate results. Each study was coded 1 or 0, indicating whether activation in early visual cortex was observed, and sets of variables associated with each model were fit to the observed results using logistic regression analysis. Three variables predicted all of the systematic differences in the probability of activation across studies. Two of these variables were identified with a perceptual anticipation theory, and the other was identified with a methodological factors theory. Thus, the variability in the literature is not random. 相似文献

Participants switched frequently between high/low and odd/even classification of a digit. The interval between a task cue and the next digit varied between blocks. In Experiment 1, the task switched predictably every two, four, or eight trials. In Experiment 2, switching predictably every four trials was compared with random switching. With predictable switching, the cost was limited to the first trial of a run. Random switching produced a more gradual approach to asymptotic performance. After one performance, control processes attenuate the resulting change in task-set bias if a further switch is likely, but this strategic modulation is soon overwhelmed by task-set priming through further performances. Preparation reduced switch costs but not interference from the irrelevant attribute: Control of interference appears to be reactive, not proactive. Switch costs did not increase with run length, suggesting that retrieval of the task set last associated with the stimulus did not contribute to switch costs. 相似文献

Primitive processes involved in auditory stream formation are measured with indirect, objective method. A target melody interleaved with a distractor sequence is followed by a probe melody that was identical to the target or differed by 2 notes. Listeners decided whether the probe melody was present or not in the composite sequence. Interleaved melody recognition is not possible when distractor sequences have the same mean frequency and maximum contour crossover with target melodies. Performance increases with mean frequency separation and timbral dissimilarity and is unaffected by the duration of the silent interval between composite sequence and probe melody. The relation between this indirect task measuring the interleaved melody recognition boundary and direct judgments measuring the fission boundary is discussed. 相似文献

Switching between tasks of unequal familiarity: the role of stimulus-attribute and response-set selection 总被引:6,自引:0,他引:6

It has been reported that it is harder to switch to a strong, well-practiced task from a weaker, less-practiced task than vice versa. Three experiments replicated this surprising asymmetry and investigated how it is affected by a reduction in interference between tasks. Experiment 1 progressively delayed the onset of the stimulus attribute associated with the stronger task. Experiments 2 and 3 separated the response sets of the tasks. Both manipulations reduced, without eliminating, interference of the stronger with the weaker task but reversed the asymmetry of switch costs, resulting in a larger cost of switching to the weaker task. The results are interpreted in terms of a model of the interactions between control input, task strength, and task priming. 相似文献

Do separate processes identify objects as exemplars versus members of basic-level categories? Evidence from hemispheric specialization 总被引:2,自引:0,他引:2
When an object is identified as a specific exemplar, is it analyzed differently than when it is identified at the basic level? On the basis of a previous theory, we predicted that the left hemisphere (LH) is specialized for classifying objects at the basic level and the right hemisphere (RH) is specialized for classifying objects as specific exemplars. To test this prediction, participants were asked to view lateralized pictures of animals, artifacts, and faces of famous people; immediately after each picture was presented, a label was read aloud by the computer, and the participants decided whether the label was correct for that picture. A label could name the object at either the basic level (e.g., bird) or as an exemplar (e.g., robin). As predicted, we found that basic-level labels were matched faster when pictures were presented in the right visual field (and hence encoded initially in the LH), whereas exemplar labels were matched faster when pictures were presented in the left visual field (and hence encoded initially in the RH). 相似文献

The association between pathological gambling and attempted suicide was examined using data from a prevalence study conducted in Edmonton, Alberta, Canada. The sample size was 7,214, the questionnaire was the Diagnostic Interview Schedule, and diagnoses were made on a lifetime basis according to DSM-III criteria. Logistic regression analysis was performed, with attempted suicide as the dependent variable. The odds ratio for pathological gambling was statistically significant (odds ratio = 4.91; 95% confidence interval = [1.41,17.1]) when major depression was the only comorbid mental disorder in the model. As terms for additional mental disorders were included, pathological gambling ceased to be statistically significant. It was concluded that a history of pathological gambling is associated with previous attempted suicide, and that the association may be due to a common factor--"mental illness." 相似文献
