Four rats were trained to lever press under a discriminated avoidance/escape schedule in which separately signalled safe and warning periods were 100 sec and 32 sec respectively. The auditory and not the visual component of the compound warning signal became associated with the discriminative control of lever pressing. Avoidance behavior also came under temporal control, in that the probability of lever pressing increased as the warning period progressed. Timing began with the onset of the warning signal rather than the offset of the safe signal. However, after the warning signal had been progressively eliminated, timing began with the offset of the safe signal. When neither signal was normally available, the temporal distribution of avoidance behavior changed markedly. Drifts in the temporal distribution of lever pressing occurred throughout the study; these were manipulated for two animals. 相似文献

Tables of the exact distributions of number of matches are given for small decks having the same number of cards in each suit. Several approximate distributions are considered for use with larger decks, and some indication of the goodness of the approximations is given.The calculations for this paper were done while the writer was working on a project sponsored by funds from the Ford Foundation. The writer wishes to express his gratitude to Dr. Frederick Mosteller for his constant help and encouragement during the writing of this paper. 相似文献

This study examined whether children’s perceptions of maternal nonsupportive reactions to sadness (active discouragement and non-response) influenced children’s loneliness and classroom popularity indirectly through their effects on children’s sadness inhibition and self-perception of social competence. Participants were children in grades 3–6 from a university affiliated public elementary school (N = 175; 53 % females; 37 % racial/ethnic minority). Children reported on the frequency of their mother’s active discouragement and non-response of their sadness, as well their own sadness inhibition, self-perceived social competence, and loneliness. Classroom peers reported on children’s popularity. Results indicated that perceived maternal non-response to sadness was indirectly related to classroom popularity and loneliness through the effect on children’s self-perception of social competence. In contrast, perceived maternal active discouragement of sadness was indirectly related to children’s classroom popularity through the effect on children’s sadness inhibition. These results support the consideration of active discouragement and non-response as distinct constructs and indicate the likelihood of different pathways of influence in predicting emotional and social outcomes such as loneliness and classroom popularity. 相似文献

Dennis Fox argued in a Special Perspective contribution that psychologists ought to mount a campaign to demonstrate the adverse impact of the activities of large corporations on social and individual well-being (Fox, 1996). This Special Perspective takes issue with Fox's position in terms of the inadequacy of any supporting data and the failure to consider adequately the wideranging implications of recommendations such as the elimination of shareholder limited liability. © 1998 John Wiley & Sons, Ltd. 相似文献

Michael A. Gilbert 《Argumentation》1995,9(5):837-852
Coalescent argumentation is a normative ideal that involves the joining together of two disparate claims through recognition and exploration of opposing positions. By uncovering the crucial connection between a claim and the attitudes, beliefs, feelings, values and needs to which it is connected dispute partners are able to identify points of agreement and disagreement. These points can then be utilized to effect coalescence, a joining or merging of divergent positions, by forming the basis for a mutual investigation of non-conflictual options that might otherwise have remained unconsidered. The essay proceeds by defining and discussing argument, position and understanding. These notions are then brought together to outline the concept of coalescent reasoning. 相似文献

A culturally and economically diverse group of fifth to seventh graders (n = 361) from Boston-area public schools rated their perceptions for liking and difficulty of core academic subjects, including math and science, and their attributions for explaining performance on a math test. Inconsistent with earlier work, girls and boys reported similar perceptions of core subjects, with all students reporting a relatively high liking of math and science. Girls' and boys' attributional patterns for success in math were somewhat consistent with earlier findings, but not their attributions for lack of success. Observations of the math and science classrooms in the study indicated that most teachers, aware of gender equity issues, attempted to teach their students in a gender-fair manner. This factor may account for differences between current findings and those from past studies.Special thanks to Dr. Adele Wolfson for her advice and support. Thanks also to Dr. Lee Cuba and Lillian Sun for their assistance with statistical analyses; to Dr. Beth Hennessey for help with the measure; to Drs. Ken Hawes, Barbara Beatty, and Susan Reverby for connections into schools; to Dr. Martha Pott for suggestions on the original document; to the teachers and principals who granted permission to conduct the research; and to the student participants. Appreciation is also extended to an anonymous reviewer for insightful comments. 相似文献
