In the first experiment, in which two successively presented free-form visual patterns varied in their similarity to each other, subjects had to decide, in one condition, if the patterns were “identical” and in two other conditions if the patterns were “similar.” Qualitative individual differences in the effect of similarity on the time required to make a decision were found in the “identity” condition, and these differences interacted with the “similarity” conditions. The individual differences and the experimental effects are interpreted in terms of a two-process model of the visual comparison process—a holistic matching process that is sometimes accompanied by an analytic difference detection process. In the second experiment, the same subjects repeatedly categorized subsets of the free-form visual patterns on the basis of similarity. There appeared to be no individual differences in the subjects’ perceptions of similarity, but subjects’ perceptions did differ from the assumptions made by the experimenters when they established the response criteria for the first experiment. 相似文献

A white noise stimulus (85 dB) was used to investigate differences in heart rate (HR) and skin conductance (SC) responsivity of 32 male subjects. The subjects were divided into high and low body boundary (HB and LB) groups, according to Fisher's (1970) revised scoring system of Holtzman Inkblot responses. The hypothesis predicting a significantly larger HR response, that is resistant to habituation, for the LB group, was confirmed. The prediction that the HB group would reveal a larger SC amplitude response accompanied by a shorter recovery time, was supported for the latter. The results confirmed the hypothesis, based on behavioral observations, that the HB individual experiences stress less intensely than the LB person. It also points to individual differences as an important variable in evaluating noise as a stressor. 相似文献

The present study examined the relationship between the Type A coronaryprone behavior pattern and the magnitude of cardiovascular response induced by varying levels of environmental challenge. In a 2 × 2 experimental design, Type A and B (noncoronary-prone) subjects (n= 80) were randomly assigned to either high or low challenge instructional conditions for both the cold pressor (CP) and a choice reaction time task (RT). Overall, across both tasks, Type A subjects responded with greater systolic blood pressure (SBP) and heart rate (HR) elevation than Type B subjects. While these differences between the Types tended to be larger in the high challenge condition, some differences were also observed under low challenge. Component analyses of the Pattern revealed that high hostile/competitive Type A's responded to both low and high challenge instructions in the CP and RT tasks with physiologic elevations comparable to that displayed by globally defined Type A's receiving high challenge instructions. The present findings tentatively suggest that (a) high hostile/competitive Type A's respond to even mild challenge with enhanced physiologic response; (b) globally defined A's tend to evidence the physiologic elevations when specifically challenged; and (c) Type B's show much smaller physiologic reactions to such challenges. Consistent with previous research, comparison of Type A assessment techniques revealed that the Rosenman diagnostic interview was a better predictor of physiologic response than other questionnaire methods. Two hypotheses are advanced and future research recommended regarding possible relationships between environment, behavior, physiology, and disease. 相似文献

A laboratory study examined the effects of task design and reward contingency upon task performance and satisfaction and upon behavioral and attributional measures of intrinsic and extrinsic motivation. Intrinsic and extrinsic motivation were defined by the task content-task consequence distinction. Both the task design and reward contingency factors were found to yield significant multivariate F ratios, but their interaction was not significant. Subjects in the contingent pay condition had higher performance quantity than those in the noncontingent condition. Subjects in the enriched task condition produced higher quality units than those in the nonenriched condition. Both contingent pay and enriched task conditons yielded higher task satisfaction and increased attributions of performance to intrinsic factors. Results were discussed in terms of cognitive evaluation theory and the distinction between intrinsic and extrinsic motivation. 相似文献

A battery of measures was used to assess conflict between mothers and young adolescents (females and males, 11 to 15 years of age). Two groups of families, one composed of a distressed clinical sample (N = 38), the other a nondistressed normative sample (N = 40), participated. The assessment battery included retrospective judgments, frequency estimates, self-monitored home recording, and tape-recorded discussion of a home problem. Content of assessment measures tapped aspects of parental control, decisionmaking, self-reported interaction behavior, arguments, interaction behavior rated by independent “blind” observers, frequency and anger-intensity of specific problematic issues, and perceptions of positive and negative behaviors of the other family member. Based on univariate analyses, 21 of the 26 defined variables discriminated significantly in the predicted direction. Maternal and adolescent reports of behavior and independent ratings of tape-recorded interaction emerged as strong and consistent discriminators. Stepwise multivariate discriminant analysis provided successful classification of 100% of the families based on the inclusion of nine variables. In a cross-validation sample, 84% of the families were correctly classified. Implications for systematic outcome research as well as clinical application are discussed. 相似文献

Simultaneous observational recordings were made in vivo, via an observation mirror, and via closed circuit television. Three of nine observers had extensive experience recording behavior in vivo; three had extensive experience recording behavior via mirror; and three had extensive experience recording via television. Observers recorded nine categories of disruptive behavior for children in a special class setting. Frequencies of behavior recorded in vivo, via mirror, and via television differed significantly for only one category, vocalization. There were no significant main effects or interactions involving the observers' previous experience. Occurrence reliability coefficients computed within and between media demonstrated the similarity of observer agreement in all three media. Data collection procedures using an observational mirror or closed circuit television appear to be reasonable alternatives to in vivo observation in circumstances similar to those in the present study. 相似文献

Remarriage is analyzed from the perspective of family boundaries and roles. The nuclear and remarriage family models are compared, and the process that begins with the formation of the first-marriage nuclear family and ends with the formation of a second-marriage family is conceptualized in terms of changing family boundaries and roles. Discussions with remarriage group members provide concrete illustrations of this process and suggest solutions to some of the problems confronting remarriage family members. 相似文献

Five event schedules (75:0, 75:25, 75:0:0, 72:25:0, 75:12.5:12.5) were examined in a size discrimination task with penny rewards and plastic token markers. The subjects were 100 fourth graders (mean age = 9.4 years) and 100 undergraduates of both sexes. Whether or not the event probabilities summed to unity proved to be a more important determiner of terminal performance than the number of response alternatives in the task (p < .01). Females maximized more than males (p < .001) and college students more than fourth graders (p < .001). Greater maximization was exhibited by fourth graders in the reward condition (p < .01). These reward effects appeared to be more consistent with a detrimental-effects-of-reward interpretation than either utility or expectancy interpretations. 相似文献
