The allostasis theory states that, as addiction develops, alcohol is consumed to relieve negative affect rather than produce positive effects. This study aimed investigate the real-time subjective effects of in individuals with use disorder (AUD) and those prone by virtue having comorbid depressive (DEP). Participants (N=221) completed high-resolution ecological momentary assessments during 3-hour monitoring one drinking episode non-alcohol their natural environment. also daily mood surveys...
Patients with bipolar disorder (BD) and schizophrenia (SZ) often show decision-making deficits in everyday circumstances. A failure to appropriately weigh immediate versus future consequences of choices may contribute these deficits. We used the delay discounting task individuals BD or SZ investigate their temporal decision making. Twenty-two BD, 21 SZ, 30 healthy completed along neuropsychological measures working memory cognitive function. Both groups discounted delayed rewards more...
<h3>Background</h3> Passive exposure to combustible cigarette use has been shown act as a cue increase smoking urge. Given the resemblance of e-cigarettes and other electronic nicotine delivery systems (ENDS) cigarettes, we examined whether these devices could also desire urges in those passively exposed. <h3>Methods</h3> Young adult daily smokers (age 18–35 years; N=60) completed subjective ratings before after study confederate drinking bottled water (control cue) then either or...
Abstract Performance on complex decision‐making tasks may depend a multitude of processes. Two such tasks, the Iowa Gambling Task (IGT) and Balloon Analog Risk (BART), are particular interest because they associated with real world risky behavior, including illegal drug use. We used cognitive models to disentangle underlying processes in both tasks. Whereas behavioral measures from IGT BART were uncorrelated, revealed two reliable cross‐task associations. Results suggest that similarly...
Use and awareness of electronic nicotine delivery systems (ENDS; also known as cigarettes or e-cigarettes) has increased rapidly in recent years, particularly among young adults. As use ENDS resembles traditional smoking both hand-to-mouth movements inhalation exhalation behaviors, we determined whether exposure to e-cigarette via video would act a cue elicit urge desire for combustible cigarette. Young adult smokers (mean age 26.3 ± 4.1 years) were randomized view brief montage...
Prior research shows that in-person exposure to electronic nicotine delivery systems (ENDS) use increases desire for cigarettes and ENDS. However, less is known about the impact of cues delivered during remote interactions. This study extends previous cue work by leveraging a confederate-delivered cue-delivery paradigm evaluate dual vaping (vs. sole smoking) on reactivity an ENDS in individuals who smoke cigarettes. N=52 users (DU; current both combustible ENDS) N=54 smokers (SS; only)...
Background Heavy drinking smokers ( HDS ) have more difficulty quitting smoking than lighter drinkers or abstainers. The opioid antagonist naltrexone may improve quit rates and reduce alcohol use in drinker–smokers, but its relative efficacy with a range of patterns is unknown. current study tested the hypothesis that would show differential benefit versus placebo to moderate‐to‐light nondrinking terms improving outcomes reducing consumption. Methods Adult N = 315) enrolled 12‐week,...
Background: Patients with bipolar disorder (BD) exhibit aberrations in auditory event‐related potentials (ERPs), although the relationships between these measures and mood state at testing, comorbid psychiatric illness, presence of psychotic features, medication usage are unclear. The purpose this study was to investigate factors ERP BD patients. Methods: An ‘oddball’ discrimination task used elicit ERPs from 69 patients type I 52 healthy controls. were placed into subgroups based upon their...
This data pool (N = 617) comes from 10 independent studies assessing performance of healthy participants (i.e., no known neurological impairments) on the Iowa gambling task (IGT)—a measuring decision making under uncertainty in an experimental context. Participants completed a computerized version IGT consisting 95 – 150 trials. The consist choices each participant trial, and resulting rewards losses. are stored as .rdata, .csv, .txt files, can be reused to (1) analyze participants; (2)...
Aims: Chronic cannabis users show impairments on laboratory measures of decision making which reflect risk factors for initiation and continued use cannabis. However, the differential sensitivity these tasks to has not been established. Moreover, studies date have often lacked assessment psychiatric histories other illicit substances, both may influence outcomes. The current study aimed address limitations by (1) including multiple types tasks, (2) implementing Probabilistic Reversal...
Abstract Background High‐resolution ecological momentary assessment (HR‐EMA) can assess acute alcohol responses during naturalistic heavy drinking episodes. The goal of this study was to use HR‐EMA examine behavior and subjective in risky drinkers (moderate–severe disorder [MS‐AUD], social [HD]) light (LD). We expected that would endorse greater stimulation reward, with lower sedation, than LD, even when controlling for amount consumed. Methods Participants ( N = 112; 54% male, M ± SD age...
