Correlations were computed between United States per capita consumption of cigarettes and 41 different foods for the years 1964–1977 and 1968–1973. There were significant negative correlations between consumption of cigarettes and sugar. Few other foods showed any relationship to cigarette consumption. These findings corroborate the results of a recent human laboratory study of cigarette smoking and food consumption and a recent animal study of the effects of nicotine on food consumption, taste preferences, and body weight. Taken together, these studies suggest that the inverse relationship between cigarette smoking and body weight may be partially explained by changes in consumption of sweet-tasting high caloric foods. 相似文献

Certain doses of pentobarbital consistently increased the rate of pecking engendered by a fixed-ratio schedule of 30 responses in a group of 13 pigeons, and still higher doses produced decrements in rate of responding. For individual subjects, the dose-effect functions were qualitatively similar, but differed with respect to the doses producing the maximum increase and subsequent decrease in rate. In general, the maximum occurred at lower doses and the decrement was greater at the highest dose in the birds with the highest control rates. It was also possible to distinguish between the effects of pentobarbital and several other drugs on the behavior maintained by FR 30. The results indicate that changes in rate of responding on FR 30 after drug administration are dose-dependent, drug-specific effects. 相似文献

The presence or absence of pulses of low intensity electric shock was used as a discriminative stimulus to control responding under fixed ratio reinforcement in the squirrel monkey. Initially brief periods of nonreinforcement were lengthened only when discriminative control was evident. Discriminative control was studied by (1) varying the duration of nonreinforcement periods; (2) reversing the stimulus conditions correlated with reinforcement and nonreinforcement periods; and (3) determining the minimum shock intensity necessary to maintain discriminative control. Stimulus control was not reliably affected by d-amphetamine, chlorpromazine, or morphine. The discriminative control by pulses of low intensity electric shock was similar to that by other discriminative stimuli, except that the control developed slowly and was better when the pulsing shock was correlated with reinforcement than when correlated with nonreinforcement. 相似文献

This process evaluation study examined what variables moderate and mediate treatment effects on days in stable housing and
client satisfaction for homeless mentally ill clients. In general, demographic characteristics did not moderate either outcome
variable. Housing contacts, entitlement contacts, mental health contacts, and supportive services were significant mediators
of the treatment effect on days in stable housing. Program contacts, mental health contacts, and supportive services were
significant mediators of client satisfaction.

A multiple probe across behaviors design, replicated across participants, assessed the effectiveness of constant time delay in teaching appropriate peer reinforcement and grocery words to 3 elementary students with moderate intellectual disabilities. Additionally, pretests and posttests assessed the acquisition of the participants' observational learning (acquisition of peers' grocery words) and instructive feedback (related information supplied by the teacher in the consequent event). Results indicate that the participants learned (a) how to appropriately reinforce peers, (b) to read their grocery words, (c) some of the targeted stimuli of their peers, and (d) much of the instructive feedback that was associated with each of the grocery words. Maintenance data indicate that the participants maintained their target grocery words at high levels of accuracy. 相似文献

This article addresses whether the state has the right to medicate involuntarily a defendant who is incompetent either to plead guilty or to stand trial for the purpose of restoring legal competence. It first presents the constitutional background concerning incompetence and the right of prisoners generally to refuse psychotropic medication. Then the article examines the individual and state interests that must be considered to decide specifically whether the state may involuntarily medicate a criminal defendant solely for the purpose of restoring competence. Although the individual interests are strong, the article contends that the state does have a right to medicate involuntarily defendants charged with most crimes to restore trial competence, and that adequate remedies are available to ensure that medicated defendants receive a fair trial. 相似文献
