Objectives: Attribution of symptoms as medication side effects is informed by pre-existing beliefs about medicines and perceptions of personal sensitivity to their effects (pharmaceutical schemas). We tested whether (1) pharmaceutical schemas were associated with memory (recall/recognition) for side effect information (2) memory explained the attribution of a common unrelated symptom as a side effect.Design: In this analogue study participants saw the patient leaflet of a fictitious asthma drug listing eight side effects.Main outcome measures: We measured recall and recognition memory for side effects and used a vignette to test whether participants attributed an unlisted common symptom (headache) as a side effect.Results: Participants who perceived pharmaceuticals as more harmful in general recalled fewer side effects correctly (rCorrect Recall = ?.273), were less able to differentiate between listed and unlisted side effects (rRecognition Sensitivity = ?.256) and were more likely to attribute the unlisted headache symptom as a side effect (rside effect attribution = .381, ps < .01). The effect of harm beliefs on side effect attribution was partially mediated by correct recall of side effects.Conclusion: Pharmaceutical schemas are associated with memory for side effect information. Memory may explain part of the association between pharmaceutical schemas and the attribution of unrelated symptoms as side effects. 相似文献

In this study we examined the relationships among parental social supportive behaviors for children’s weekday and weekend
outdoor physical activity (OPA). Thirty-nine girls and 29 boys 8 to 11 years wore pedometers for 7 days. Sixty-five mothers
and 50 fathers responded to a social support questionnaire about OPA that was comprised of four dimensions: encouragement,
playing with, use of activity as family recreation, and watch. After controlling for age and sport participation, regression
analyses indicated that mothers’ use of activity as recreation was positively associated with girls’ weekday OPA. On the weekend,
fathers’ play with son was positively related to OPA. The effectiveness of family-based activity interventions depends on
when parents have opportunities to be present for their child’s activity and gender differences in the support provided. 相似文献

Patients with unilateral neglect of the left side bisect physical lines to the right whereas individuals with an intact brain bisect lines slightly to the left (pseudoneglect). Similarly, for mental number lines, which are arranged in a left-to-right ascending sequence, neglect patients bisect to the right. This study determined whether individuals with an intact brain show pseudoneglect for mental number lines. In Experiment 1, participants were presented with visual number triplets (e.g., 16, 36, 55) and determined whether the numerical distance was greater on the left or right side of the inner number. Despite changing the spatial configuration of the stimuli, or their temporal order, the numerical length on the left was consistently overestimated. The fact that the bias was unaffected by physical stimulus changes demonstrates that the bias is based on a mental representation. The leftward bias was also observed for sets of negative numbers (Experiment 2)--demonstrating not only that the number line extends into negative space but also that the bias is not the result of an arithmetic distortion caused by logarithmic scaling. The leftward bias could be caused by a rounding-down effect. Using numbers that were prone to large or small rounding-down errors, Experiment 3 showed no effect of rounding down. The task demands were changed in Experiment 4 so that participants determined whether the inner number was the true arithmetic centre or not. Participants mistook inner numbers shifted to the left to be the true numerical centre--reflecting leftward overestimation. The task was applied to 3 patients with right parietal damage with severe, moderate, or no spatial neglect (Experiment 5). A rightward bias was observed, which depended on the severity of neglect symptoms. Together, the data demonstrate a reliable and robust leftward bias for mental number line bisection, which reverses in clinical neglect. The bias mirrors pseudoneglect for physical lines and most likely reflects an expansion of the space occupied by lower numbers on the left side of the line and a contraction of space for higher numbers located on the right. 相似文献

People overweight certainty, even when certainty is only an illusion. A vaccine that was described as 100% effective against
70% of disease targets was preferred to one described as 70% effective against 100% of disease targets (Studies 1 and 2).
The appeal of 100% extends beyond the probability attribute. In Study 2, participants preferred both of the vaccines above
to normatively equivalent vaccines that were less than 100% effective toward fewer than 100% of targets. In Study 3, participants
preferred a 100% discount on a cup of coffee every 10 days to other more frequent, but lower amount, discounts. This preference
evaporated, however, when savings were framed as points rather than as percentage discounts. We propose that people view 100%
as a salient reference point and overweight it in those domains where it cannot be exceeded (e.g., probability, discount);
the overweighting is weaker in domains where 100% can be exceeded (e.g., target range, points). 相似文献

The present study examined the performance of 78 students with learning disabilities and 71 normally achieving students in regular Form 1 (Grade 6) classes on three validity indexes of the Perception of Ability Scale for Students, a measure of academic self-concept. The three indexes assess consistency of responding, negative or positive response biases, and misrepresentation of self-perceptions in terms of unrealistic perceptions of perfection in school. Analysis showed that learning disabled students obtained significantly lower Full Scale scores than the normal students, but no significant differences appeared on the three validity indexes. Users of the test can be confident that learning disabled students respond to items in as valid a manner as other students. Having specific learning problems in school should not interfere with response patterns on this scale. 相似文献

The selection interview remains the most popular method by which organizations select employees, yet it is also widely criticized for being vulnerable to bias and unfair discrimination. This paper draws upon two specific areas of attribution research: cross-cultural studies of attributional processes and studies of intergroup attributional bias in order to discuss how attributional processes can contribute to unfair discrimination in selection interviews. It is argued that unfair discrimination can arise in two ways: first, as a consequence of ethnocentric attributional biases on the part of interviewers when explaining the behaviour of candidates associated with in-group or out-group status; second, as a result of different patterns of attributions manifest by candidates from diverse cultural groups. 相似文献

The present study investigated moderately impaired aphasic subjects' ability to integrate information across sentences by having them identify antecedents for ambiguous pronouns in brief narratives. In order to disambiguate the pronouns, the subjects had to consult either textual cues and/or extratextual cues. In addition, the subjects' ability to retrieve factual information was measured by having them identify explicitly stated noun referents. The results show that the aphasic subjects had significant difficulty using textual cues to resolve referents when the referents were not readily accessible through world knowledge. The patients had little difficulty interpreting referents which were recoverable from world knowledge or were stated explicitly. The explanatory power of world knowledge effects, grammatical class effects, memory effects, and linguistic integration effects in accounting for the deficit pattern observed is considered. 相似文献

The effects of deep muscle relaxation on anxiety were studied in a systematic desensitization context. A Sensory Decision Theory analysis of anxiety ratings to controlled imagery showed that relaxed Ss were significantly more sensitive to phobic properties of the controlled imagery than nonrelaxed Ss. The results are discussed in terms of Wolpe's theoretical basis for systematic desensitization. Sensory Decision Theory is presented as a useful technique for measuring the effects of therapy on emotional states. 相似文献
