The major purpose of the present investigation was to examine the combined influence of variations in foreperiod length (1.0, 5.0 sec) and catch trial frequency (0.0, 0.1, 0.2) on simple reaction time (RT) magnitude when verbal mediation was permitted and when it was not. A significant foreperiod length, catch trial frequency, mediation type interaction was obtained supporting the notion that all three factors influence a common process (i.e. Sternberg 1969), here called ‘preparation’. More specifically, for the non-mediation group, foreperiod length and catch trial frequency had both additive (0.0 vs 0.1) and interactive (0.1 vs 0.2) effects on mean simple RT while only catch trial frequency significantly altered simple RT for the mediating group. In all instances, mean simple RT increased significantly when some catch trials were employed as opposed to when none were used, a finding which was interpreted as reflecting an induced preparation decrement upon the introduction of catch trials. 相似文献

This research attempted to establish relationships between locus of control, self-esteem, and traditional-nontraditional behavior. It was hypothesized that (1) women tending toward internality and high self-esteem should be more likely to manifest nontraditional behaviors, as evidenced through career-oriented roles, and to rank these roles as their primary source of satisfaction; and (2) women tending toward externality and low self-esteem should be more likely to manifest traditional behavior, as evidenced through family-oriented roles, and to rank these roles as their primary source of satisfaction. The sample consisted of 91 White females in a southern metropolitan area. The data were collected using a survey design. As expected, high self-esteem internals were more likely to manifest nontraditional behavior. Contrary to expectation, low self-esteem externals were more nontraditional in role orientation. 相似文献

A simple stochastic model is formulated in order to determine the optimal time between the first test and the second test when the test-retest method of assessing reliability is used. A forgetting process and a change in true score process are postulated. The optimal time between tests is derived by maximizing the probability that the respondent has not remembered the response on the first test and has not had a change in true score. The resulting test-retest correlation is then found to be a linear function of the true reliability of the test, where the slope of this function is the key probability of not remembering and having no change in true score. Some numerical examples and suggestions for using the results in empirical studies are given. Specific recommendations are presented for improved design and analysis of intentions data.This research was made possible by a grant from the Center for Food Policy Research, Graduate School of Business, Columbia University, New York, New York, 10027. 相似文献

Predicting contraceptive behavior from attitudes: a comparison of within- versus across-subjects procedures 总被引:2,自引:0,他引:2
Within- versus across-subjects procedures for predicting behavior from attitudes were contrasted. Each procedure requires a comparison among attitudes in order to generate a prediction; the comparison is either among the same attitudes held by different people (across subjects) or among different attitudes held by the same person (within subject). It was hypothesized that the within-subject model provides a more adequate explanation of behavior from attitudinal constructs and, hence, more accurate prediction of behavior from attitudes than does the across-subjects model. To test this view, a sample of 349 married couples was administered a questionnaire containing measures of three attitudinal components--affect, cognition, and conation--toward each of four contraceptive methods--oral contraceptives, IUD, diaphragm, and condoms. Contraceptive behavior was assessed 1 year later. In support of the hypothesis, the within-subject predictions bore a significantly stronger relation to the behavioral criteria than did the across-subjects predictions. This effect was consistent for each of the three components of attitude, for the prediction of behavior and behavioral intention, for male and female respondents, and for a variety of contraceptive behaviors. In addition, both the within- and the across-subjects analyses demonstrated a clear rank ordering in the predictive validity of the three attitudinal components: Conation was a better predictor of behavior than was affect, which, in turn, was better than cognition. 相似文献

Examined the interpersonal responses of persons engaged in dyadic interactions with confederates who enacted either depressed or socially appropriate roles and appeared either with or without a physical disability. Subject negative evaluations of confederates were indirectly obtained from a thought-listing measure. The overt behaviors of subjects were surreptitiously recorded on videotape and measures of verbal and nonverbal behavior were acquired. Subjects spoke less to the depressed targets and had significantly higher rates of negative evaluations of these persons. In addition, subjects gazed less at the depressed confederates. These effects were not moderated by target physical appearance. Findings are discussed as they relate to social models of depression and the stigmatizing effects of disability. 相似文献

This study surveyed a randomly selected group of Approved Supervisors of the American Association for Marriage and Family Therapy (n = 280) and their supervisees (n = 266) on their perceptions of the primary supervisor interpersonal skill used in supervisory incidents that had a positive effect on supervisee development. Supervisor directiveness was the most identified skill by both supervisors and supervisees.This study was funded in part by grants from the Research Committee of the American Association for Marriage and Family Therapy; the Agricultural Experiment Station, Purdue University; and the School of Liberal Arts and Sciences, Purdue University Calumet. 相似文献

The language patterns of 10 mothers and 10 fathers with their firstborn 3-year-old sons were compared. Ten-minute mother-son and father-son conversations were recorded independently in the home during a free-play session with standard play mterials. The findings of this study indicate that although mothers and fathers used a similar number of utterances in conversing with their sons over a 10-minute period, their patterns of speech were different on a number of quantitative measures including MLU, MLU of five longest utterances, percent of imperatives, and percent of questions. In general, fathers' communication was viewed as more controlling and involving the child less, while mothers' communication was viewed as more child-centered and involving the child more. 相似文献
