Delay discounting refers to a decline in the value of reward when it is delayed relative immediately available. tasks are used identify indifference points, which reflect equal preference for two dichotomous alternatives differing both delay and magnitude. Indifference points key assessing shape delay-discounting gradient because they allow us isolate effect on value. For example, if at 1 week maximum $1,000, point $700 we know that, that participant, 1-week corresponds 30% reduction This...
Tobacco use is the leading cause of death globally and in United States. After decades decline, driven by decreases combusted tobacco use, nicotine product has increased due to electronic delivery systems, also known as e-cigarettes or vapes. Preclinical models self-administration can serve important lodestars search for effective intervention prevention tactics. Current variants preclinical have substantial limitations, however. Therefore, we created rodent system (RENDS), a novel low-cost...
In delay discounting, temporally remote outcomes have less value. Cigarette smoking is associated with steeper discounting of money and consumable outcomes. It presently unclear whether smokers discount health more than nonsmokers. We sought to establish the generality steep for different types in cigarette smokers. Seventy participants (38 32 nonsmokers) completed 4 hypothetical outcome delay-discounting tasks: a gain $500, loss temporary boost health, cure from debilitating disease....

Delay discounting is the process by which a commodity loses value as delay to its receipt increases. Rapid predicts various maladaptive behaviors including tobacco use. Typically, of different outcomes has been compared between cigarette smokers and nonsmokers. To better understand relationship modes use, we examined differences in smokers, smokeless users, e‐cigarette non‐tobacco users. In present study, all participants completed 8 titrating delay‐discounting tasks: $100 gain, $500 loss,...
We examined the effects of outcome framing on delay discounting. In Experiment 1, participants completed four delay-discounting tasks. one monetary task, money was framed in units dollars (＄50), and other, handfuls quarters (equal to ＄50). food clear (e.g., 100 M&Ms), servings 10 M&Ms). When dollars, discounted less by compared discounting quarters. as units, also how they servings. 2, two tasks for ＄50 or 200 quarters) determine if results 1 were due differences handling costs. dollars....
The present study examined persistence and relapse of reinforced behavioral variability in pigeons. Pigeons emitted four‐response sequences across two keys. Sequences produced food according to a lag schedule, which response sequence was followed by if it differed from certain number previous sequences. In Experiment 1, delivered for that satisfied schedule both components multiple schedule. When reinforcement removed one component (i.e., extinction), levels decreased only component. 2,...
Most delay discounting studies use tasks that arrange progressions in which the spacing between consecutive delays becomes progressively larger. To date, little research has examined using other progressions. The present study assessed whether form or steepness of varied across different Human participants completed three with time delays: a standard (increasing duration delays), linear (equal and an inverse progression (decreasing delays). Steepness was generally reduced, remained so,...
Delay discounting is the loss in value of an outcome as a function its delay. The present study focused on examining trait‐like characteristic delay preclinical animal model. Specifically, we were interested whether there was positive relation between 2 different outcomes rats. That is, would rats that discount delayed food steeply also water steeply? In addition, examined how session‐to‐session variability could be attributed to differences subjects (trait variability) and within (state...
Alcohol is the most commonly used drug in United States and alcohol abuse can lead to use disorder. disorder a persistent condition relapse rates following successful remission are high. Many factors have been associated with for disorder, but identification of these has not well translated into preventative utility. One potentially important factor, concurrent nicotine use, investigated as causal factor Nicotine increases value other stimuli environment may increase alcohol. If alcohol,...

Alcohol is the most commonly abused drug in USA and many people suffer from alcohol use disorder. Many factors are associated with disorder, but causal role of comorbid nicotine has not been extensively considered. Nicotine reward-enhancing properties may increase value alcohol. Monoamine oxidase inhibition increases self-administration effects nicotine. We assessed effect combination a used monoamine inhibitor (tranylcypromine) on using progressive ratio schedule reinforcement rats....
