Drawing on equity theory, two possibilities that might reduce resentment of the donor following the receipt of aid which cannot be repaid were investigated: (a) the cost to the donor is minimized, and (b) the recipient has an opportunity to aid a third party. The results provide evidence that the recipient will like the donor less and be less willing to request future aid when he cannot repay the aid than when he can. Weak support was received by the hypothesis that the tendency to like the donor less when the aid cannot be repaid will be stronger, the greater the perceived cost. Support was found for the hypothesis that the decreased willingness to request future aid when the aid cannot be repaid will be stronger, the greater the perceived cost. Support was found for the hypotheses that the recipient will like the donor more and be more willing to request future aid when he has an opportunity to aid a third party than when he cannot aid anyone. 相似文献

Nine children, ages 4 through 7 yr, matched-to-sample on fixed-ratio, fixed-interval, variable-ratio, and variable-interval schedules of reinforcement. Simultaneous, zero-delay, and 2-sec delay matching were employed. Distributions of errors, in which the greatest number of errors occurred at the ordinal position immediately after reinforcement with fewer errors occurring at subsequent positions in the ratio, were produced by six of six children on fixed-ratio schedules for zero-delay and both of two children for 2-sec delay matching. Only two children of seven produced similar error distributions on simultaneous matching for fixed-ratio reinforcement. Variable-ratio schedules produced slightly lower accuracy for most subjects and no systematic error patterns for any subject. Error distributions occurred for all of the five children who experienced fixed-interval schedules for zero-delay matching. Peak error production occurred in the second fourth of the interval. Similar patterns were not produced on variable-interval schedules of equal reinforcement density. Schedule control of complex discriminated operants in children resembles control over similar responses of nonhuman animals. 相似文献

Concern for the rights and safety of individuals has caused clinical researchers to develop informed consent protocols for research involving human subjects. The applicapability of these regulations to social science research is often tenuous, since such research usually focuses on populations rather than individuals, and potential damage is apt to be political rather than personal. In cross-cultural social research, the protocols developed by Western clinical researchers may be not only ludicrously inapplicable, but intrusive and disruptive within the cultural context, raising questions of the intellectual imperialism of Western research ethics. 相似文献

A home-based Language Training Programme was carried out with pre-school and school-age severely mentally handicapped children, over a 16–18-month period. Compared to control groups, the experimental groups did not show significantly greater progress on normreferenced measures of language development, although all groups showed significant improvement over time. The implications of these findings are discussed in the light of a number of methodological problems with the study. 相似文献

The determinants of leadership seniority in laboratory groups were investigated in two experiments. In both experiments a procedure was used in which individual group members were periodically replaced throughout 7 generations. The individuals within the groups folded origami products and traded with other groups so as to earn quarters. In the first experiment the effect of social familiarity on seniority was investigated by comparing a set of standard groups with a set of rotational groups in which the group members moved from group to group between generations and thus always interacted with strangers. There was less seniority in the rotational groups. In the second experiment the effect of experience on seniority was investigated by comparing a set of standard groups with a set of experienced groups in which the new group members were recruited from the standard groups. There was less seniority in the experienced groups. It was found in both experiments, in agreement with previous research, that over generations the subjects earned increasing amounts of money and worked with increasing speed and efficiency. 相似文献

Three experiments with musicians and nonmusicians (N=338) explored variations of Deutsch’s musical scale illusion. Conditions under which the illusion occurs were elucidated and data obtained which supported Bregman’s suggestion that auditory streaming results from a competition among alternative perceptual organizations. In nExperiment 1, a series of studies showed that it is more difficult to induce the scale illusion than might be expected if it is accepted that an illusion will be present for most observers despite minor changes in stimuli and experimental conditions, The stimulus sequence seems better described as an ambiguous figure. Having discovered conditions under which the scale illusion could be reliably induced, Experiments 2 and 3 manipulated additional properties of the stimulus (timbre, loudness, and tune) to provide cues to streaming other than pitch and location. The data showed that streaming of this sequence can be altered by these properties, supporting the notion of a general parsing mechanism which follows general gestalt principles and allows streaming by many stimulus dimensions. Finally, suggestions are made as to how this mechanism might operate. 相似文献

In Experiment 1, four developmentally delayed adolescents were taught an A-B matching-to-sample task with nonidentical stimuli: given Sample A1, select Comparison B1; given A2, select B2. During nonreinforced test trials, appropriate matching occurred when B stimuli appeared as samples and A stimuli as comparisons, i.e., the sample and comparison functions were symmetrical (B-A matching). During A-B or B-A matching test trials in which familiar samples and correct comparisons were presented along with novel comparisons, the subjects selected the correct comparisons. In tests with familiar samples and both incorrect and novel comparisons, subjects selected the novel comparisons, demonstrating control by both positive ("matching") and negative ("nonmatching") stimulus relations in A-B and B-A arrays. In Experiment 2, 12 developmentally delayed subjects were taught a two-stage arbitrary-matching task (e.g., A-B, C-B matching). Test sessions showed sample-comparison symmetry (e.g., B-A, B-C matching) and derived sample-comparison relations (e.g., A-C, C-A matching) for 11 subjects. These subjects also demonstrated control by positive and negative stimulus relations in the derived relations. 相似文献
