Schedule-induced drinking (SID) can occur when food-deprived rats are given access to water while receiving pellets on an intermittent reinforcement schedule. These conditions can increase water intake excessively. The possible role of adventitious reinforcement of postpellet drinking was assessed by testing whether response-reinforcer contiguity, the relative predictiveness of a response, and whether it is marked are important in the development of SID. Rats exposed to a short interpellet interval acquired SID most rapidly, with this acquired drinking response maintained when animals were transferred to a longer interpellet interval, thus indicating an easy-to-hard effect (Experiment 1). Further experiments demonstrated that a stimulus (a brief-flashing house light) occurring prior to pellet delivery could block the acquisition of SID (Experiment 2), while a lick-contingent tone, intended to increase the associability of this response, produced more rapid acquisition of SID (Experiment 3). Analysis of lick distributions revealed that licking became concentrated in the first half of an interpellet interval only after several sessions. Overall, the results indicated that similar factors affect the acquisition of both SID and instrumental conditioning with delayed reinforcement, as is consistent with a superstitious conditioning account of SID development. 相似文献

We describe a computational model to explain a variety of results in both standard and false recognition. A key attribute of the model is that it uses plausible semantic representations for words, built through exposure to a linguistic corpus. A study list is encoded in the model as a gist trace, similar to the proposal of fuzzy trace theory (Brainerd & Reyna, 2002), but based on realistically structured semantic representations of the component words. The model uses a decision process based on the principles of neural synchronization and information accumulation. The decision process operates by synchronizing a probe with the gist trace of a study context, allowing information to be accumulated about whether the word did or did not occur on the study list, and the efficiency of synchronization determines recognition. We demonstrate that the model is capable of accounting for standard recognition results that are challenging for classic global memory models, and can also explain a wide variety of false recognition effects and make item-specific predictions for critical lures. The model demonstrates that both standard and false recognition results may be explained within a single formal framework by integrating realistic representation assumptions with a simple processing mechanism. 相似文献

This article builds on assertions in Richardson's (2012, this issue) Major Contribution on counseling for work and relationship. In this reaction, I expand on the relevance and potential of the counseling for work and relationship perspective to enrich the field of counseling psychology. My comments focus on three considerations to further extend the cultural relevance of Richardson's work and relationship perspective: (1) broadening sources of dignity, (2) centering knowledge of marginalized communities, and (3) promoting psychologists' critical consciousness. Richardson's perspective holds great promise for being a guiding heuristic to inform counseling psychology research, theory, and practice. 相似文献

Occurrence of the home disadvantage in professional ice hockey was examined by analyzing shootout data from 2005 through 2008. Results indicated that teams involved in shootouts playing at their home arenas did not lose significantly more games at home than on the road. Results did not support the hypotheses that emphasize the roles of physical contact and diffusion of responsibility in accounting for past failures to find the home disadvantage in professional ice hockey. 相似文献

Children tell prosocial lies for self- and other-oriented reasons. However, it is unclear how motivational and socialization factors affect their lying. Furthermore, it is unclear whether children’s moral understanding and evaluations of prosocial lie scenarios (including perceptions of vignette characters’ feelings) predict their actual prosocial behaviors. These were explored in two studies. In Study 1, 72 children (36 second graders and 36 fourth graders) participated in a disappointing gift paradigm in either a high-cost condition (lost a good gift for a disappointing one) or a low-cost condition (received a disappointing gift). More children lied in the low-cost condition (94%) than in the high-cost condition (72%), with no age difference. In Study 2, 117 children (42 preschoolers, 41 early elementary school age, and 34 late elementary school age) participated in either a high- or low-cost disappointing gift paradigm and responded to prosocial vignette scenarios. Parents reported on their parenting practices and family emotional expressivity. Again, more children lied in the low-cost condition (68%) than in the high-cost condition (40%); however, there was an age effect among children in the high-cost condition. Preschoolers were less likely than older children to lie when there was a high personal cost. In addition, compared with truth-tellers, prosocial liars had parents who were more authoritative but expressed less positive emotion within the family. Finally, there was an interaction between children’s prosocial lie-telling behavior and their evaluations of the protagonist’s and recipient’s feelings. Findings contribute to understanding the trajectory of children’s prosocial lie-telling, their reasons for telling such lies, and their knowledge about interpersonal communication. 相似文献

Using a sample of 196 undergraduate students, the present study investigated the psychometric properties of the Spiritual
Fitness Assessment, a measure of spiritual fitness designed for use by health and fitness professionals. Examination of inter-item
consistency produced satisfactory alpha coefficients for the total test and its three subscales. Correlations of the SFA with
measures of spirituality and spiritual well-being provide support for convergent validity. Significant positive correlations
with a measure of self-esteem suggest that the test has satisfactory criterion validity. Correlations with age, sex, and a
measure of social desirability indicate that the SFA is significantly, though only moderately, affected by demographic variables
and motivated response tendencies. Factor analysis of the SFA items indicate that the test is factorially complex and subscales
may need to be refined to better measure their intended constructs. Overall, the results of the study suggest that the test
may be useful for evaluations of spiritual fitness. Further research with samples drawn from different populations is needed
on the test to better establish its reliability and validity. 相似文献

This paper studies an economy whose agents perceive their consumption possibilities subjectively, and whose preferences are defined on what they subjectively experience, rather than on those alternatives that are objectively present. The model of agents’ perceptions is based on intuitionistic logic. Roughly, this means that agents reason constructively: a solution to a problem exists only if there is a construction by which the problem can be solved. The theorems that can be proved determine how an agent perceives a set of alternatives. A dual model relates perceived alternatives to a shared language, which the agents use in trading. So perceptions relate objective alternatives to an agent’s subjective view of them, and reporting dually relates an agent’s subjective world to a shared language. It turns out that an appropriately modified notion of competitive equilibrium always exists. However, in contrast with standard results in economic theory, competitive equilibrium need not be efficient. 相似文献

This paper describes how different self‐construals influence people's perception of temporal distance and in turn their task evaluation. We hypothesize that people with a more accessible interdependent (vs. independent) self‐construal perceive future events as temporally more proximal, and that people's reaction toward a task is intensified when the temporal distance to the task matches (vs. mismatches) their self‐construal. Across four studies, we showed that individuals with a more accessible interdependent self‐construal (Study 1) and East Asians (Study 2) perceived future events as more proximal than those with a more accessible independent self‐construal and European Americans. Further, when considering a task at a temporal distance that fits their self‐construal, individuals perceived a pleasant task as more motivating (Study 3) and an unpleasant task as less motivating (Study 4).

From the perspective of terror management theory, awareness of death induces a need for validation of important values. Thus, for women who place a high value on their appearance (e.g., high self-objectifiers), mortality salience should increase positive reactions to objectifying experiences relative to women who do not highly value appearance. Two studies supported this hypothesis. Self-objectification moderated favorable reactions to objectifying stimuli (Study 1) and state self-esteem in response to an objectifying comment (Study 2) when women were primed with death. Together, the studies illustrate the complexity of reactions to objectification and, by highlighting conditions in which objectification serves a psychological function, help to explain the pervasiveness of the phenomena. 相似文献
