A rapid inexpensive technique for changing from intravenous drug self-administration (DSA) to liquid reinforcement is described. Utilizing a standard peristaltic-type infusion pump typically used in DSA experiments and a specially designed drinking cup, the changeover from intravenous DSA to liquid reinforcement can be accomplished in a few minutes at a cost of less than $10. 相似文献

A random utility model of choice was developed by combining the basic ideas of the well-known theories of Thurstone and Restle. The new model has exactly the same number of free parameters as Tversky's Elimination-by-Aspects model. Furthermore, both models were found to fit, with equal accuracy, the data reported by Rumelhart and Greeno, and Tversky. It was concluded that although the two theories are not identical, they may be difficult to discriminate empirically. 相似文献

Two studies were conducted to specify what attributes of life change events increase the risk of future psychological distress. It was hypothesized that the events perceived as both undesirable and uncontrollable would be most likely to be linked to subsequent distress. In the fiist study, which employed a retrospective methodology, 117 college students reported the life changes that occurred to them over a 3-month span and indicated the desirability and controll-ability of each event. These subjects also responded to an inventory, used in studies of community mental health, to assess symptoms of psychological distress. The findings indicated that only events perceived as both undesirable and uncontrollable were related to the incidence of psychological distress symptoms. Study 2 examined the same hypothesis in a prospective methodology. As in Study 1, only undesirable, uncontrollable life events were significantly related to subsequent psychological distress symptoms. The results of both studies implicate the importance of perceptions of control over aversive events in understanding the link between real life outcomes and illness. 相似文献

Paper/pencil psychological tests such as the Minnesota Multiphasic Personality Inventory (MMPI) are difficult to complete independently by patients with limited hand function. This paper describes a voice recognition system developed to allow patients with no hand function to take the MMPI independently. Profiles generated by this system are not statistically different from those generated by standard MMPI booklet format. Limitations and possible extensions of the system as it currently exists are discussed. 相似文献

Substantial differences exist across ethnic groups and sexes in generational changes in status among groups residing in Hawaii. Despite these generational differences across groups, age differences in personality are remarkably consistent across sexes and racial/ethnic groups, and the few Sex x Age, Ethnicity x Age or Sex x Ethnicity x Age interactions account for little variance in scores. It is concluded that age/generational differences in personality factor scores in these populations result from age and not, to any major degree, from cohort effects. 相似文献
