Contrast effects were obtained in rats in the consumption of saccharin solutions in three different paradigms. Degree of negative contrast varied as a function of concentration disparity, but not equally in the three procedures. Successive negative contrast occurred following shifts from 0.15% to either 0.075% or 0.05% saccharin but did not occur following shifts to 0.10% or 0.125% saccharin. Some degree of simultaneous contrast was obtained with all four concentration disparities. Anticipatory contrast, where the intake of the first substance is suppressed by a more preferred second substance, occurred only in the case of the 0.05%-0.15% difference in concentrations. It was suggested that the several contrast paradigms engage somewhat different psychological processes differentially involving emotional, sensory, and associative mechanisms, but all lead to behavior based on relative value. A modification of Toates's (1981) incentive model of ingestive behavior was suggested to incorporate relativity effects based on both associative and nonassociative factors in the consumption of both nutritive and nonnutritive substances. 相似文献

The national incidence of juvenile suicide in adult jails and juvenile detention centers 总被引:1,自引:0,他引:1
M G Flaherty 《Suicide & life-threatening behavior》1983,13(2):85-94
Federal policy currently permits children to be placed in adult jails if they are kept separate from adult prisoners. However, past research suggests that facility and staff limitations at jails often result in juveniles being held in isolation without supervision. Based upon a national probability sample, the following hypotheses are tested: the suicide rate among children held in adult jails is higher than the suicide rate among children held in secure juvenile detention centers, and the latter rate is higher than the suicide rate among juveniles in the general population of the United States. 相似文献

Latent class analysis (LCA) provides a means of identifying a mixture of subgroups in a population measured by multiple categorical indicators. Latent transition analysis (LTA) is a type of LCA that facilitates addressing research questions concerning stage-sequential change over time in longitudinal data. Both approaches have been used with increasing frequency in the social sciences. The objective of this article is to illustrate data augmentation (DA), a Markov chain Monte Carlo procedure that can be used to obtain parameter estimates and standard errors for LCA and LTA models. By use of DA it is possible to construct hypothesis tests concerning not only standard model parameters but also combinations of parameters, affording tremendous flexibility. DA is demonstrated with an example involving tests of ethnic differences, gender differences, and an Ethnicity x Gender interaction in the development of adolescent problem behavior. 相似文献

In two experiments, memory distortions for voice pitch and speaking rate were examined. In both experiments, a significant distortion effect for voice pitch was observed, with listeners biased towards selecting voices lower in pitch than low‐pitch targets and selecting voices higher in pitch than high‐pitch targets. In contrast, for speaking rate there was little evidence for the production of memory distortions. The results are discussed in terms of transient surface properties of speech and how transience may be a factor in producing distortions. The results have implications for how errors arise during earwitness testimony for a suspect's voice. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

The interactive effects of feeding and drinking schedules were investigated in three experiments. Twenty-four hour water-deprived rats consumed their entire obligatory water intake prior to feeding, whereas 24-hr food-deprived rats consumed only small quantities of food prior to drinking. This drinking was apparently due to a shift of water stores rather than an actual negative water balance. Experiment 3 investigated the effects of 24, 48, or 72 hr of water, food, or total deprivation. Water-deprived rats did not adequately suppress food intake and became thirstier than totally deprived rats. The effects of total deprivation were essentially identical to those of food deprivation. These experiments indicate the degree to which deprivation schedules impose restrictions on the reinforcement parameters of behavioral experiments. 相似文献

Research in the area of sex differences in coalitional behavior has produced inconsistent results that may be partially resolved through an examination of personality and attitudinal differences between males and females. The responses of males and females to the Shure and Meeker Personality/Attitude Schedule were analyzed and the sexes differed in their elevation on six major factors. A subsample of each sex participated in a coalition game situation. Four of the six personality and attitude factors were related to prenegotiation stage indices of coalition formation. It was suggested that the role of sex differences in coalitional behavior may be mediated by sex role socialization differences. 相似文献

The present study was designed to investigate the differential influences of exposure to life tragedies and religious contradictions on the tendency to engage in religious questioning (quest orientation). A replication and extension of a study by Burris, Jackson, Tarpley, and Smith (1996) was conducted to determine whether exposure to religious contradictions alone or life tragedies alone would influence quest orientation. Additional experimental conditions attempted to address Batson's (1982) theoretical position that quest orientation results “from a process of cognitive restructuring in response to existential questions” (p. 162). The results replicated Burris et al. (1996) and also showed that exposure to tragedy alone led to increases in quest orientation. The results did not support the idea that exposure to contradictions increased quest orientation. Unexpectedly, some evidence was found that exposure to tragedy influenced extrinsic orientation. 相似文献

Leader-Member Exchange Theory (LMX) offers a way to better understand nuances of the salesperson-sales manager relationship. The study reported here employs leader-member exchange theory to evaluate how sales employees develop trust with their managers. Findings show that salespeople's perceptions of procedural justice positively influence salespeople's commitment to the organization, and thereby their satisfaction with the job. Suggestions are provided concerning how sales organizations can train managers to manage consistently and thereby build trust and commitment in salespeople. 相似文献
