Many parents report that shopping trips with children can be an exhausting and harassing experience. However the ecological features of supermarkets that contribute to disruptive behaviour have not been clearly delineated. A pilot study sought the views of 100 parents and 40 store personnel on the nature of difficulties parents experienced with children on trips to the supermarket. Subjects were drawn from staff and shoppers in each of four urban supermarkets. Results from a structured interview showed that many parents either experienced problems with their own children (62%) or believed that other parents experienced child management problems (99%). Both parents and store personnel considered demandingand screaming to be the most frequently encountered problem, and over half the parents considered that toy departments were the most disruptive areas. A second study comprised an observational analysis of children's behaviour in three supermarkets. This study examined whether different areas of the store were associated with differing levels of disruptive behaviour and product disturbance in children. The study also examined the effects of the presence of store personnel, time of day and socio-economic status on levels of store disruption. Systematic observations of the behaviour of children, parents and store personnel were conducted in each of three observation zones, during the morning and afternoon, in each store. Results showed that highest levels of disruption occurred in areas where attractive merchandise (e.g. toys) were on display, confirming parents impressions and during afternoon shopping trips. The effects of socio-economic status and the presence of store personnel were non significant. The implications of the results for treatment research aiming to develop advice packages for parents for use in community settings are discussed. 相似文献

The aim of the study was to examine how plausibility influences attributions about the cause of perceived arousal. Subjects watched one of three arousing (humorous, sexual, aggressive) or a nonarousing televised program under conditions of appropriate or inappropriate interpersonal spacing. The subjects then completed a questionnaire indicating how crowded they felt and rating the movie on a number of dimensions. The results indicated that under close interpersonal distances, subjects felt less crowded while watching the arousing movies than while viewing the nonarousing movie. There were no differences in the experience of crowding between the movie conditions under the far interpersonal distance conditions. In addition, subjects rated the arousing movies as more arousing under close as opposed to far interpersonal distance conditions. Further, the humorous movie was viewed as more funny, and the violent movie was rated more violent under the close as opposed to the far conditions. Finally, there was a tendency to enjoy the arousing movies more under the close conditions, while the reverse effect was found for the nonarousing movie. It was argued that the arousing movies reduced the experience of crowding under close interpersonal conditions because subjects attributed their arousal to the movies rather than to the spatial restrictions. It was further suggested that the results showed that individuals will attribute their arousal to salient stimuli in their environment that could plausibly be sources of arousal. The results not only offer support for an attribution model of crowding, but they also show that depending on the individual's attribution, spatial conditions that can give rise to crowding may increase enjoyment of events in the environment. 相似文献

Five pigeons were trained over 43 experimental conditions on a variety of concurrent variable-interval schedules on which the forces required on the response keys were varied. The results were well described by the generalized matching law with log reinforcement ratios and log force ratios exerting independent (noninteractive) effects on preference. A further analysis using the Akaike criterion, an information-theoretic measure of the efficiency of a model, showed that overall reinforcement rate and overall force requirement did not affect preference. Unlike reinforcement rate changes, force requirement increases did not change the response rate on the alternate key, and an extension of Herrnstein's absolute response rate function for force variation on a single variable-interval schedule is suggested. 相似文献

Integration theory models predict that sequences increasing or decreasing in intimacy should have less impact on attraction than constant intimate or nonintimate disclosures. Male and female subjects (N= 159) conversed with a videotaped confederate. Each confederate relayed six disclosures in one of five intimacy sequences: increasing, constant high, decreasing, constant low, and random. The confederate either had a choice of topics and sequence or they were imposed. Substantial support was found for integration theory models. The constant high disclosers by choice were liked more than their no-choice controls and the constant low disclosers by choice were disliked more than their no-choice controls. The mixed sequences (increasing, decreasing, and random) produced no significant differences. 相似文献

An integrative approach emphasizing both psychological and physiological components in force perception has started to emerge in motor psychophysics. In this experiment, the relation between isometric force (produced by the elbow flexors~ and perceived force was examined over a range of forces maintained until maximal endurance. A contralateral-limb matching procedure in which subjects estimated the force of a sustained, constant force contraction by contracting their unfatigued arm at regular intervals was employed. A linear increase in perceived force was observed during the fatiguing contractions, the rate of which depended on the level of force exerted. The sensation of force at maximal endurance was also found to vary with the force exerted. Based on the similarity between these results and those derived from electromyographic studies, we propose that observers use the efferent input to the muscle in preference to its afferent responses in judging the force of muscular contractions. 相似文献

The authors conducted an experiment to test a theoretical explanation of social facilitation based on the biopsychosocial model of challenge and threat. Participants mastered 1 of 2 tasks and subsequently performed either the mastered (i.e., well-learned) or the unlearned task either alone or with an audience while cardiovascular responses were recorded. Cardiovascular responses of participants performing a well-learned task in the presence of others fit the challenge pattern (i.e., increased cardiac response and decreased vascular resistance), whereas cardiovascular responses of participants performing an unlearned task in the presence of others fit the threat pattern (i.e., increased cardiac response and increased vascular resistance), confirming the authors' hypotheses and the applicability of the biopsychosocial model of challenge and threat to explain these results. 相似文献

Objective:
To develop and evaluate a decision aid designed to prepare patients of advanced maternal age for counseling about prenatal diagnostic testing.
Setting:
A regional genetics center.
Design:
A before/after study.
Interventions:
Participants used an audioguided workbook to learn about options and outcomes and to clarify personal risks, values, questions, and predispositions.
Subjects:
21 women of advanced maternal age and 17 spouses.
Main outcome measures:
Knowledge of prenatal testing alternatives, decisional conflict, level of anxiety, and acceptability of the decision aid.
Results:
After using the decision aid, participants had significantly reduced decisional conflict (uncertainty) and a significant increase in knowledge. There was no effect on state or trait anxiety. More than three-quarters of participants were satisfied with the length, clarity, balance, and acceptability of the decision aid.
Conclusions:
The decision aid shows promise as a useful aid for preparing couples for counseling. 相似文献

This study examined the effects of publicly-posted performance feedback on the in-hospital behavior of patients residing on a self-management unit at a large, state operated, psychiatric treatment facility. When contrasted to a baseline phase in which staff received weekly information regarding patients' performance, scores in six of the eight assessment areas improved when this information was provided directly to patients. The authors' conclude that performance feedback may be a useful adjunct to inpatient treatment programs because it clarifies programmatic expectations, helps focus attention on developing strategies or interventions to meet those expectations, and encourages active treatment participation from patients and staff. 相似文献
