Abstract This paper is a response to Eiser's (1996) call for a unifying theoretical perspective that would bridge the gap between 'individualistic and ‘social’ approaches to studying human social behaviour in general, and health behaviour in particular. While agreeing with Eiser's premise that it makes no sense to study cognition, affect, and behaviour independently of social context, the present paper takes issue with certain features of his argument that a connectionist approach provides the needed unifying theoretical framework. It is suggested that if connectionism can describe the psychological processes underlying social behavior better than non-connectionist theories, this would provide more compelling evidence of its value than claims that it affords new theoretical insights. 相似文献

Abstract The relevance and significance of the concept of a ‘competition of cues’ for the understanding of symptom perception in childhood asthma was investigated during detection of externally applied resistive loads on breathing. The concept predicts that subjects would respond less frequently and less accurately during external stimulation. The sample consisted of 36 children with and 36 without asthma, aged 7-18 years. Detection of airflow was measured in a neutral and in an external stimulation condition. The children breathed through a facemask and responded to changes in airflow by pressing a button. The stimulus presented and withdrawn was analogous to a decrease in lung function (Forced Expiratory Volume in one second) of 39%. Accuracy of detection of airflow was defined as correct minus false positive responses to load stimuli. The results showed that children with and without asthma responded significantly less frequently during external stimulation than in the neutral condition. However, the accuracy of detection among non-asthmatics was not affected by external stimulation. Children with asthma responded significantly more accurately during external stimulation. The results are discussed in the light of children's accuracy to perceive actual airways obstruction. 相似文献

When Klein, W. M. gave participants absolute and comparative risk information (crossed experimentally) they were more disturbed by being above than below average, but not by being at higher rather than lower risk. The current experiment tests whether Klein's findings extend to situations involving lower risk figures more typical of genuine health risks, assesses participants’ understanding of the information, and directly compares responses of US and UK samples. Participants were presented with hypothetical information about comparative and absolute risks of deep vein thrombosis. There was a main effect of absolute risk information on disturbance and precaution intentions in the US sample, but no effects of comparative information on these measures in either sample. Understanding was poor among participants receiving both pieces of risk information. Future studies should include measures of understanding to establish whether people are failing to understand what they are told or failing to respond systematically to what they understand. Practically, the findings caution against providing comparative risk information when communicating low risk figures. 相似文献

The ability of high-functioning individuals with autism to perceive facial expressions categorically was studied using eight facial expression continua created via morphing software. Participants completed a delayed matching task and an identification task. Like undergraduate male participants (N = 12), performance on the identification task for participants with autism (N = 15) was predicted by performance on the delayed matching task for the angry-afraid, happy-sad, and happy-surprised continua. This result indicates a clear category boundary and suggests that individuals with autism do perceive at least some facial expressions categorically. As this result is inconsistent with findings from other studies of categorical perception in individuals with autism, possible explanations for these findings are discussed. 相似文献

The aim of the study was to assess: (a) developmental changes in attention, response inhibition, and face-information processing using the new Balloons task and (b) to evaluate the association between measures derived from the task with reported behavior problems. One hundred and thirty-four typically developing children (53 boys and 81 girls) were tested with the Balloons. Their parents and teachers completed the Child Behavior Checklist. Our results validate the Balloons as a reliable task with significant effects of manipulations in difficulty level (speed, processing load, and processing type). The results suggest that face-information processing undergoes significant changes during the age period between 7 and 13 years with significant gender differences. Modest but significant correlations were found between the Balloons' measures and behavior problems. 相似文献

Visuospatial working memory (VSWM) and visual perception were examined in two groups aged 11–13, one with children displaying symptoms of nonverbal learning disability (NLD) (n = 18) and the other a control group without learning disabilities (n = 18). The two groups were matched for general verbal abilities, age, gender, and socioeconomic level. The children were presented with VSWM tests involving visual and spatial-simultaneous processes, and also with a classical visual illusion, a classical ambiguous figure, as well as visual perception tests specifically devised for the present study. Results revealed that performance of children at risk of NLD was worse than controls in some VSWM and in visual perception tests without memory involvement; these latter required comparisons of visual stimuli and locations in space with distractors. Moreover, the two groups differed in perceiving the classical ambiguous figure. Findings are discussed in the light of both theoretical and clinical implications. 相似文献

Objective
A previous randomised controlled trial demonstrated that a cognitive behavioural therapy (CBT) self-management intervention significantly improved irritable bowel syndrome (IBS) symptoms and disability compared to treatment as usual (TAU). The current study analysed additional data to establish whether; 1) cognitive, behavioural and emotional factors hypothesized to perpetuate IBS symptoms and disability changed following CBT and, 2) ascertain if changes in these factors over the intervention period mediated treatment effects 6-months later.Method
IBS patients (CBT = 31, TAU = 33) completed measures pre-and-post intervention including: Brief Illness Perception Questionnaire, Hospital Anxiety & Depression Scale and Cognitive and Behavioural Responses to Symptoms Questionnaire. Path models were evaluated to determine whether changes in cognitive and behavioural factors over the treatment period mediated treatment effects.Results
Compared to TAU, CBT patients showed significant positive changes on several cognitive variables but not anxiety and depression following intervention. Positive change in illness perceptions following intervention mediated the treatment effect on improved IBS symptom severity and social adjustment six months later. Changes in damaging beliefs mediated the effect on social adjustment.Conclusions
Change in cognition rather than mood mediated treatment related improvements. Changing negative perceptions of IBS appears to be a particularly important treatment mechanism. 相似文献228.

Background and objectives: Terrorism can heighten fears and undermine the feeling of safety. Little is known, however, about the factors that influence threat and safety perception after terrorism. The aim of the present study was to explore how proximity to terror and posttraumatic stress reactions are associated with perceived threat and safety after a workplace terrorist attack. Design and methods: A cross-sectional questionnaire survey was administered to employees in 14 of 17 Norwegian ministries 9–10 months after the 2011 bombing of the government headquarters in Oslo (n = 3520). Results: About 198 of 1881 employees completing the survey were at work when the bomb exploded. Regression analysis showed that this high-exposed group had elevated perceived threat (β = 0.36; 95% CI = 0.19 to 0.53) and reduced perceived safety (β = ?0.42; 95% CI = ?0.62 to ?0.23) compared to a reference group of employees not at work. After adjusting for posttraumatic stress reactions, however, proximity to the explosion no longer mattered, whereas posttraumatic stress was associated with both high perceived threat (β = 0.55; 95% CI = 0.48 to 0.63) and low perceived safety (β = ?0.71; 95% CI, ?0.80 to ?0.63). Conclusion: Terror-exposed employees feel more threatened and less safe after a workplace terrorist attack, and this is closely linked to elevated levels of posttraumatic stress reactions. 相似文献

Abstract Anxiety in face of environmental risks is common, but few attempts have been made to assess individual differences psychometrically and to validate the measures in samples that have suffered from exposure to neurotoxic substances. The present study deals with this problem in two ways. First, levels of general anxiety were determined in two large independent samples of workers who were exposed to multiple organic solvents and in their nonexposed referents. In both samples, anxiety was substantially higher in exposed subjects than in their referents. Second, an Environmental Worry Scale (EWS) was developed and validated in three samples. This 17-item instrument and its 8-item subscale yielded satisfactory psychometric properties and also succeeded in discriminating solvent exposed from nonexposed subjects. Finally, the EWS was used in a structural equation model that was designed to predict the intention to avoid chemicals. The worry factor served as a mediator between exposure and intention, whereas exposure by itself did not influence intentions. 相似文献

ABSTRACT Forty-one men and 67 women undergraduate students, as well as 35 men and 27 women Royal Canadian Mounted Police (RCMP) officers, rated the abusiveness of intimate partner violence (IPV) vignettes portraying each possible gender combination of victim and perpetrator (Harris &; Cook, 1994). Rating differences according to victim and perpetrator gender, occupation (student or RCMP officer), and participant gender were anticipated. Analyses found that student and RCMP ratings of abuse severity were both highest for the male-female scenario. However, the RCMP considered the female-male, male-male, and female-female scenarios to be more abusive than did the students. Our findings suggest that, while the RCMP appeared to be more sensitive to male and same-sex victims than students, both groups remain somewhat biased. 相似文献
