A method and an apparatus are described for measuring the point at which subjects elect to stop smoking when cigarette smoke is delivered more rapidly than in typical smoking. The device allows either the subject or the experimenter to control the volume of smoke and the interval between puffs. The device delivers reliable quantities of particulate matter from cigarette smoke. Subjects retested a week apart exhibited consistent stopping points. 相似文献

A confederate requester asked subjects to write letters for an educational campaign after they had completed a battery of tests and received either deviant or nondeviant feedback. Half of the subjects were led to believe that the requester had knowledge of their test performance; the remaining half believed that the confederate did not know their test scores. Within these conditions, some subjects believed that complying with the request would involve future meetings with the requester while others were not led to anticipate any future interaction. As expected, deviants complied more than nondeviants replicating Freedman and Doob's (1968) results; however, neither the secret/known nor the future interaction variations produced effects. Contrary to the prediction that deviants are compliant because they wish to avoid mistreatment, secret deviants complied slightly more than known deviants. Compliance was discussed as instrumental in improving self-image. 相似文献

In a 3 × 3 factorial experiment with 3 additional cells, 329 male or female subjects working with two same-sex confederates (A and B), received either voluntary, involuntary, or no help from A after which attraction to A and B were measured for one-fourth of the subjects. The remaining subjects were assigned to a second set of tasks and were induced to help A, help B, or were not given an opportunity to help, after which they completed attraction and mood measures. Subjects were more likely to volunteer help after the second task when they had received prior help. Receipt of help led to more liking for the helper and the helper was liked more when subjects were able to reciprocate. Attraction and mood results are discussed in relation to attractiveness mediation, modeling, and indebtedness explanations for reciprocity. 相似文献

The gain from selection (GS) is defined as the standardized average performance of a group of subjects selected in a future
sample using a regression equation derived on an earlier sample. Expressions for the expected value, density, and distribution
function (DF) of GS are derived and studied in terms of sample size, number of predictors, and the prior distribution assigned
to the population multiple correlation. The DF of GS is further used to determine how large sample sizes must be so that with
probability .90 (.95), the expected GS will be within 90 percent of its maximum possible value. An approximately unbiased
estimator of the expected GS is also derived. 相似文献

Intensive interviewing of counselors, supervisors, clients, and community workers associated with a sample of Youth Opportunity Centers led to the conclusion that assumptions of client-centered therapy are untenable in such settings. The assumptions not found tenable are: (a) client comes voluntarily; (b) client wants help; (c) client accepts counselor's authority; (d) client comes as individual; (e) counselor accepts client. Because of bureaucratic conditions of government programs, because of poverty and demoralization of clients, and because of race and other differences, counseling (except of a highly directive sort) is not possible. A group approach which takes into account the organized nature of the client population is personally recommended and described. 相似文献

Five rhesus monkeys were tested on performance of an auditory discrimination and a delayed response test with a sliding scale of increasing difficulty after treatment with (a) 0·2 to 0·5 mgm./kgm. reserpine, (b) 150 mgm./kgm. meprobamate, (c) an equivalent saline injection, and (d) no treatment. Both drug treatments resulted in a severe deficit on the auditory discrimination and no change or improvement in delayed response performance. The auditory deficit was not due simply to an increased latency of response.
It is suggested that these results support the hypothesis that reserpine and meprobamate reduce the utilization of sensory information. 相似文献
