In a field study of helping behavior carried out in 48 “convenience” grocery stores, customers tried to purchase for $1.00 a product clearly labeled as costing from $1.15 to $1.50. Amount of help by white clerks (allowing the purchase for $1.00) varied as a function of sex of customer and race of customer. Black male customers were helped least often. Neither the dress of the customers (casually-dressed or well-dressed) nor the racial makeup of the store's clientele was significantly related to helping. Implications of these findings for concepts of same-race bias and “reverse discrimination” in helping are discussed.  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

This paper seeks to identify some of the more compelling arguments put forward by those who oppose or criticise personal counselling in schools. These arguments cannot be dismissed lightly, and counsellors will have to give them serious consideration if a satisfactory resolution of the issues is to be achieved.  相似文献

The study reports relationships between teachers' belief systems (Harvey), a teacher-pupil interaction measure of classroom influence, pupils' perception of the dimate of the dassroom, and pupils' academic achievement. Results demonstrate that more complex teachers encourage more pupil influence, and are perceived as having a more origin climate. In classrooms of high pupil influence and perceived origin climate, the pupils have higher academic achievement. These results are discussed in terms of the theory of personal causation and are cited as evidence for the value of the study of action sequences as related to verbal-utterances of the actors.  相似文献

Key pecking and treadle pressing in pigeons were compared under concurrent (key-treadle) and single-operant differential-reinforcement-of-low-rate schedules of food reinforcement ranging from 5 to 60 sec (concurrent procedure) or 5 to 120 sec (single-operant procedure). Under both procedures, the two operants followed the same general law: decreasing response rate and reinforcement rate and increasing number of responses per reinforcement as a function of increasing schedule interval. High correlations were found between key pecking and treadle pressing for the measures of response rate, reinforcement rate, and responses per reinforcement. Regression equations allowed the prediction of treadle pressing from key pecking. More bursting occurred in responding to the key, and key pecking showed a more precise temporal discrimination than treadle pressing. A test for sequential dependencies between key and treadle responses showed significant dependencies not only under the concurrent procedure but also in data created artificially by merging key and treadle sequences from different pigeons under the concurrent procedure and from the same pigeon under the single-operant procedure. It seems likely that the sequential dependencies found were due to the independent action of the schedule on each operant and that behavioral dependencies did not occur with the concurrent training procedure. The key-peck operant does not appear to have any special qualities that preclude its use in discovering general laws of behavior, at least under the differential-reinforcement-of-low-rate schedule. The usefulness of the key peck in other situations requires direct experimental study.  相似文献

College students were asked if they would be willing to serve as student contacts for high school students applying for admission to the university who wanted more information about student life. Students volunteered to spend more time helping a female applicant if she wanted to become a librarian than if she wanted to become an engineer, while they volunteered to spend more time helping a male applicant if he wanted to become an engineer than if he wanted to become a librarian. Results were the same when the dependent measure was the amount of time volunteered for interviews, for telephone conversations, and for letterwriting, indicating that the amount of personal contact required did not influence subjects' preference to help those whose career aspirations were sex-role appropriate more than those whose career goals were sex-role inappropriate.  相似文献
