Activity patterns in rats (Rattus norvegicus) as a function of the cost of access to four resources 总被引:2,自引:0,他引:2

Patterns of eating, drinking, wheel running, and nesting were recorded in 2 experiments in which rats (Rattus norvegicus) lived in a laboratory environment that provided food, water, a running wheel, and a nest box. Access to each resource was contingent on the completion of a fixed ratio of bar presses and once earned remained available until the resource was not used for 10 consecutive min. In all cases an increase in the access price of a resource produced a decrease in the frequency with which the resource was accessed. This reduction in bout frequency was countered by an increase in bout size, which was compensatory for eating and nearly so for drinking, but which was only partially compensatory for wheel running. Nest bout size did not change significantly as nest price increased. The bout patterns of these 4 activities changed independently of one another, and the probabilities of behavioral transitions did not indicate strong links between any pairs of activities. 相似文献

A corollary of the law of effect predicts that the larger the reinforcement, the greater the rate of responding. However, an animal must eat more small portions than large portions to obtain the same daily intake, and one would predict, therefore, that when eating smaller portions an efficient animal would eat less (conserving time and energy) and/or respond faster (conserving time). The latter of these predictions was supported by the present experiments with free-feeding rats for which portion size (pellet size or duration of feeder presentation) and portion price within meals were varied. Response rate was a function of the unit price (responses/g) of food: Rats responded faster when portions were smaller or when prices were higher. Meal size and frequency were relatively unaffected by unit price, but were influenced by the price of meal initiation. The results are discussed in relation to the economic differences between traditional operant and free-feeding paradigms and to both traditional and more recent formulations of the law of effect. 相似文献

Conflicting theories (e.g., compensatory and congruence) describe the effect of the parent–child relationship on sibling relationship quality. By identifying specific parenting factors (i.e., Care and Control) and specific aspects of the sibling relationship (i.e., Affect, Behaviors, and Cognitions), the current study sought to examine the factors related to either theory in order to better understand the sibling relationship in emerging adulthood. Data were collected from 575 undergraduate students. A factorial MANOVA tested the relationship between parenting style and sibling relationship quality, measured by the Lifespan Sibling Relationship Scale. Results primarily supported the congruence hypothesis and revealed that parental Care and Control are important variables in understanding the sibling relationship. Additionally, the findings were consistent across racial/ethnic groups. 相似文献

Several experiments and reanalyses of archival data were performed in which sets of common emotions were mapped onto visual and auditory perceptual stimuli of varying degrees of complexity. Subjects showed reliability across several different experimental paradigms and diverse stimulus sets. Furthermore, the results were reducible to a two-dimensional emotion space of valence and activity, after the work of Osgood, Succi, and Tannenbaum (1957). The perceptual locus of an aesthetic stimulus in this two-dimensional space is hypothesized to provide a first approximation to how the synesthetic qualities of a percept provide a basis for emotional responses to such stimuli. More generally, this direct mapping of percept onto emotion provides an interesting conundrum for theories of emotion research.The author acknowledges support for this research from the ADAMA training grant, MH14257, Quantitative Methods for Behavior Research, University of Illinois, Department of Psychology.

A method of indexing response relations among stimulus words on a word association test is presented utilizing the concept of mathematical sets. Two coefficients of associative relatedness are proposed and some relationships between these and a number of other coefficients are given. 相似文献

Estimates of test size (probability of Type I error) were obtained for several specific repeated measures designs. Estimates were presented for configurations where the underlying covariance matrices exhibited varying degrees of heterogeneity. Conventional variance ratios were employed as basic statistics in order to produce estimates of size for a conventional test, an -adjusted test, and -adjusted test and a conservative test. Indices for empirical distributions of two estimators of , a measure of covariance heterogeneity, were also provided. 相似文献

In June 2015, the U.S. Department of the Treasury announced that a woman would replace Hamilton on the $10 bill. In April 2016, it announced that Harriet Tubman would replace Andrew Jackson on the $20 bill, instead. After each announcement, we surveyed nationally representative samples of American adults and asked them what they thought of these proposed changes for the $10 bill (Study 1, N = 209) and the $20 bill (Study 2, N = 208). Predictors of currency preferences were gender, race, political affiliation and their respective prejudices and biases—sexism, racism, and political ideology. On the basis of social identity, system justification, and social dominance theories we predicted that privileged groups (i.e., males, Whites) and groups who desire to maintain the status quo (i.e., Republicans, conservatives, sexist and racist individuals) would prefer to leave Hamilton on the $10 bill and Jackson on the $20 bill. Results were consistent with these predictions: Overall, we found that under‐represented groups and more liberal individuals support the proposals from the U.S. Department of the Treasury. These findings suggest a bill of money is not just a piece of paper. The person depicted on U.S. currency can be perceived as an in‐group or out‐group member and this can affect judgements in line with relevant social psychological theories. 相似文献
