Medical diagnoses are often made on the basis of the presence of multiple symptoms. However, little is known about how the presence of multiple simultaneous symptoms may influence a bias in determining which symptoms are identified, in part due to a lack of an experimental analogue of this process. The current article presents a laboratory analogue of this process and explores whether over‐selectivity influences the ability to identify symptoms indicative of particular illnesses. In two experiments, participants completed a diagnosis task that required them to rate the degree to which symptoms predicted illnesses, with predictor symptoms being presented either singly or in compound. In both experiments, over‐selectivity was observed; one symptom of the compound received lower ratings, compared to the other element of the compound and the single predictor, while the other component received comparable ratings with the element. These findings are discussed in relation to associative accounts of over‐selectivity and as a procedure to study biases in medical decision making.Copyright © 2017 John Wiley & Sons, Ltd. 相似文献

The purpose of this study was to examine the effects of a 12 month exercise program on lower limb movement variability in patients with peripheral arterial disease (PAD). Participants (n = 21) with an appropriate history of PAD and intermittent claudication (IC) volunteered for this study and were randomly allocated to either a control group (CPAD–IC) (n = 11), which received normal medical therapy and a treatment group (TPAD–IC) (n = 10), which received normal medical therapy treatment and a 12 month supervised exercise program. All participants underwent 2D joint angular kinematic analysis during normal walking to assess lower limb movement variability and walking speed. Between-group differences were analyzed via mixed measures ANOVA. The 12 month supervised exercise program made no significant impact on the lower limb movement variability or walking speed of the TPAD–IC group as determined by either intralimb joint coordination or single joint analysis techniques. Long term supervised exercise programs do not appear to influence the lower limb movement variability of PAD–IC patients. 相似文献

Matching theory describes a process by which organisms distribute their behavior between two or more concurrent schedules of reinforcement (Herrnstein, 1961). In an attempt to determine the generality of matching theory to applied settings, 2 students receiving special education were provided with academic response alternatives. Using a combined simultaneous treatments design and reversal design, unequal ratio schedules of reinforcement were varied across two academic responses. Findings indicated that both subjects allocated higher rates of responses to the richer schedule of reinforcement, although only one responded exclusively to the richer schedule. The present results lend support to a postulation that positive reinforcement may have undesirable collateral effects that are predicted by matching theory (Balsam & Bondy, 1983). 相似文献

Recent research has demonstrated the utility of latency measures during the functional analysis of problem behavior; however, few studies have evaluated the utility of latency measures during subsequent treatment analyses. The current study seeks to extend the literature on the use of latency measures during the treatment of severe self‐injurious behavior (SIB). Following a latency‐based functional analysis, a treatment analysis was conducted using a hybrid procedure in which baseline sessions were terminated following the first instance of SIB, and test sessions ended after a fixed length of time. Latency to SIB was compared across conditions, whereas latency and rate measures for both SIB and functional communication responses were compared for the functional communication training condition. Results suggest that latency measures may be too sensitive during treatment analyses and that it is beneficial to use a hybrid procedure that allows for both latency and rate comparisons. 相似文献

A sample of 115 men and women between the ages of 20 and 60 completed the 30-item General Health Questionnaire together with the short-form Revised Eysenck Personality Questionnaire. The data indicate psychological distress so assessed is correlated .43 (p <.001) with Neuroticism and -.26 (p <.01) with Introversion but is unrelated to Psychoticism scores. 相似文献

A meta-analysis was conducted to test whether the use of self-report measures within the bogus pipeline (BPL) paradigm yields more valid responses than the use of self-report measures alone for assessing cigarette smoking behavior. The meta-analytic results indicate that, overall, a BPL condition resulted in a larger proportion of subjects reporting that they are frequent smokers, as compared to a self-report measure only (no pipeline) condition. Tests of categorical models indicate that the enhanced validity of self-reports within the BPL paradigm is moderated by the following variables: (a) type of BPL presentation employed, (b) type of self-report measure to which the BPL technique is compared, and (c) whether most participants are smokers (as indicated by a biochemical marker). 相似文献

These two studies investigated the influence of dispositional locus of control (LOC) on subjective and physiological responses to a novel laboratory stressor task. Across two studies, 64 healthy undergraduate students, ages 18-22, completed Levenson's (LOC) scales for internal, powerful others, and chance prior to performing a video-game task. Participants rated pretask and posttask stressfulness and coping ability (i.e., measures of primary and secondary appraisal). Cardiovascular measures (heart period, HP; preejection period, PEP; respiratory sinus arrhythmia, RSA; cardiac output, CO; systolic blood pressure, SBP; diastolic blood pressure, DBP & total peripheral resistance, TPR) were recorded during 4-minute baseline and 4-minute stressor task periods. The internal LOC factor predicted pretask reports of coping ability as well as posttask reports of stressfulness. In contrast, the powerful-others LOC factor predicted cardiac changes (HP, PEP, and RSA) during the task but not cardiac output or any other vascular change measure. These results underscore the importance of using the three subscales of the Levenson LOC to assess relationships between dispositional LOC and the response to stressors because self-reported appraisals of a task are predicted by a different component of dispositional LOC than are task-related cardiovascular functions. 相似文献

This study extends previous research concerning the association between religion and psychological health in six ways: (1)
by focusing clearly on religious attendance (church attendance); (2) by employing a robust measure of psychological distress
(GHQ-12); (3) by studying a highly religious culture (Northern Ireland); (4) by taking sex differences into account (male
or female); (5) by taking denominational differences into account (Catholic or Protestant); (6) and by obtaining a national
representative sample (N = 4,281 adults aged 16 and above). Results from a 2 (sex) by 2 (denomination) ANCOVA demonstrated that Catholics recorded
significantly lower levels of psychological health compared to Protestants, and that females showed significantly lower levels
of psychological health compared to males. In addition, females reported higher frequency of religious service attendance
than males, and Catholics reported higher attendance rates than Protestants. A significant positive association was found
between frequency of religious attendance and GHQ-12 scores, and this association was moderated by sex and denomination. In
conclusion, the results suggest that there may be sex and denominational differences in further understanding the relationship
between frequency of religious attendance and psychological health. 相似文献

Is perception of human motion affected by psychosocial resources? According to the Resources and Perception Model, perception is jointly affected by subjective threat and psychosocial resources that buffer threat. Two experiments tested whether social threat (i.e., ostracism) and psychosocial resources affect perception of human motion. Observers attempted to identify human movement in ambiguous point‐light displays after being ostracized or not ostracized. Additionally, trait resources (self‐esteem plus social support) were measured (Studies 1 and 2), and self‐affirmation was manipulated (Study 2). Study 1 showed that ostracism reduced sensitivity for detecting human motion but not among people with ample trait resources. Study 2 replicated this ostracism‐by‐trait resources interaction. It also showed that self‐affirmation improved human motion perception for all included participants but only benefited ostracized participants with ample trait resources. These studies show that a basic visual skill—detecting human motion—is jointly affected by social threats and psychosocial resources. 相似文献
