R. M. Gilbert 《Journal of the experimental analysis of behavior》1971,15(1):97-108
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

Edgar J. Gilbert 《Psychometrika》1956,21(3):253-266
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

Ronald Reagan enjoyed a successful political career. Nevertheless, his political life was affected dramatically by the fact that he was the son of an alcoholic parent. Alcoholic parents leave deep marks on their children's lives, even after those children become adults. As president of the United States, Reagan clearly demonstrated these marks. He was aloof and distant, was often a disengaged leader, showed inordinate loyalty to associates even when such loyalty became problematic, was prone to live in a world of make‐believe, married compulsive women, and craved approval and applause. Each of these behavioral characteristics was part of the psychological legacy left to this president by his long‐dead alcoholic father. Some of them damaged his presidency greatly; others, however, may well have assisted it. 相似文献

To gain a better understanding of the evolution of animal cognition, it is necessary to test and compare the cognitive abilities of a broad array of taxa. Meaningful inter-species comparisons are best achieved by employing universal paradigms that standardize testing among species. Many cognitive paradigms, however, have been tested in only a few taxa, mostly birds and primates. One such example, known as the Aesop’s Fable paradigm, is designed to assess causal understanding in animals using water displacement. To evaluate the universal effectiveness of the Aesop’s Fable paradigm, we applied this paradigm to a previously untested taxon, the raccoon (Procyon lotor). We first trained captive raccoons to drop stones into a tube of water to retrieve a floating food reward. Next, we presented successful raccoons with objects that differed in the amount of water they displaced to determine whether raccoons could select the most functional option. Raccoons performed differently than corvids and human children did in previous studies of Aesop’s Fable, and we found raccoons to be innovative in many aspects of this task. We suggest that raccoon performance in this paradigm reflected differences in tangential factors, such as behavior, morphology, and testing procedures, rather than cognitive deficiencies. We also present insight into previously undocumented challenges that should better inform future Aesop’s Fable studies incorporating more diverse taxa. 相似文献

Ecology's reputation as a holistic science is partly due to widespread misconceptions of its nature as well as shortcomings in its methodology. This article argues that the pursuit of empirical laws of ecology can foster the emergence of a more unified and predictive science based on complementary modes of explanation. Numerical analyses of population dynamics have a distinguished pedigree, spatial analyses generate predictive laws of macroecology, and physical analyses are typically pursued by the ecosystem paradigm. The most characteristically ecological laws, however, are found in biotic analyses in the functional trait paradigm. Holistic credentials for ecology may thus be restored on two bases: its accommodating complementary modes of analysis and explanation, and its having some laws within the least reductionistic mode consistent with its subject matter. These claims, grounded in the aspectual theory of Herman Dooyeweerd, lead to some suggestions for enhancing the versatility and usefulness of ecology—and other sciences—by balancing different research paradigms under a holistic vision. 相似文献
