Environmental determinants of the reinforcing effects of nicotine in humans. 1989

Experimental studies indicate instructions (told received nicotine > told received placebo) and drug history (exsmokers > never-smokers) increase the degree to which the stimulus effects of nicotine will serve as a reinforcer in humans. Cross-study comparisons and correlational data suggest schedule (concurrent > single access to nicotine and placebo), duration of exposure (longer > shorter exposure), and setting (therapeutic > experimental settings) also increase the reinforcing effect of nicotine. Empirical study of when and how environmental factors control the reinforcing effects of nicotine is crucial to specifying multicausal models of tobacco dependence.

D009042	Motivation	Those factors which cause an organism to behave or act in either a goal-seeking or satisfying manner. They may be influenced by physiological drives or by external stimuli.	Incentives,Disincentives,Expectations,Disincentive,Expectation,Incentive,Motivations
D009538	Nicotine	Nicotine is highly toxic alkaloid. It is the prototypical agonist at nicotinic cholinergic receptors where it dramatically stimulates neurons and ultimately blocks synaptic transmission. Nicotine is also important medically because of its presence in tobacco smoke.	Nicotine Bitartrate,Nicotine Tartrate
D012055	Reinforcement Schedule	A schedule prescribing when the subject is to be reinforced or rewarded in terms of temporal interval in psychological experiments. The schedule may be continuous or intermittent.	Reinforcement Schedules,Schedule, Reinforcement,Schedules, Reinforcement
D012056	Reinforcement, Social	The strengthening of a response with a social reward such as a nod of approval, a parent's love or attention.	Social Reinforcement,Reinforcements, Social,Social Reinforcements
D002638	Chewing Gum	A preparation of chicle, sometimes mixed with other plastic substances, sweetened and flavored. It is masticated usually for pleasure as a candy substitute but it sometimes acts as a vehicle for the administration of medication.	Chewing Gums,Gum, Chewing,Gums, Chewing
D003430	Cross-Sectional Studies	Studies in which the presence or absence of disease or other health-related variables are determined in each member of the study population or in a representative sample at one particular time. This contrasts with LONGITUDINAL STUDIES which are followed over a period of time.
