Two experiments are reported in which observers had to utilize information from one of two structural levels of visual stimulus patterns (large letters composed of smaller ones). They could utilize information more rapidly form one level only at the cost of slower utilization from the other. This trade off defines an empirical attention operating characteristic (AOC) which is consistent with a simple mathematical model of the perceptual process: when viewing a stimulus, the observer selects one of two alternative “attentional” strategies, where each strategy is optimal for utilizing information from one structural level, but less than optimal for the other. 相似文献

A course on cotherapy for mental health practitioners is described. The authors strongly recommend that clinicians from all disciplines be taught and trained to do cotherapy, since it is a highly effective therapeutic modality in treating individuals, families and groups. 相似文献

Perceived Control, Drive for Thinness, and Food Consumption: Anorexic Tendencies as Displaced Reactance 总被引:1,自引:0,他引:1
Although loss of perceived control has been implicated in the development of eating disorders, previous research has not directly tested the relationship between perceived control and food consumption. This study investigated the hypothesis that individuals with anorexic tendencies react to low perceived control by restricting food intake as a means of regaining a sense of control. Forty female undergraduates who scored either low or high on the Drive for Thinness Scale (Garner & Olmsted, 1984) were led to believe they would be participating in two separate studies. Perceived control was experimentally manipulated such that half of the subjects experienced low control and half experienced high control over a social situation. Under the guise of a second experiment, subjects tasted breakfast cereals and completed measures relevant to eating and body image. Results showed that subjects who were high in drive for thinness (DT) who experienced low control ate less sweetened cereal and planned to eat less at dinner than high DT subjects who experienced high control. Low DT subjects were unaffected by the control manipulation. The results are discussed in terms of displaced reactance. 相似文献

Attributions made by children and their parents for the cause of the child's clinical problem were monitored during assessment interviews. Results support previously observed differences obtained through questionnaires, with parents making more attributions than their children to characteristics of the child. This pattern was affected by variations in interview format. Parents and children differed in the locus of their attributions when interviewed individually, but these differences were not present when families were interviewed with both parents and children present. Implications for the methodology of attribution research with child-clinical populations are highlighted. 相似文献

Evidence from four studies demonstrates that social observers tend to perceive a “false consensus” with respect to the relative commonness of their own responses. A related bias was shown to exist in the observers' social inferences. Thus, raters estimated particular responses to be relatively common and relatively unrevealing concerning the actors' distinguishing personal dispositions when the responses in question were similar to the raters' own responses; responses differing from those of the rater, by contrast, were perceived to be relatively uncommon and revealing of the actor. These results were obtained both in questionnaire studies presenting subjects with hypothetical situations and choices and in authentic conflict situations. The implications of these findings for our understanding of social perception phenomena and for our analysis of the divergent perceptions of actors and observers are discussed. Finally, cognitive and perceptual mechanisms are proposed which might account for distortions in perceived consensus and for corresponding biases in social inference and attributional processes. 相似文献

A hopper dispenser designed for the study of food reinforcement in rats is described. By using ordinary rat chow, it significantly reduces the cost of reinforcing rats with food. By preventing stockpiling, it also guarantees control of the accessibility, as well as the presentation of food. 相似文献
