This paper contrasts dual-process and personality approaches in the prediction of addictive behaviors and related risk behaviors. In dual-process models, behavior is described as the joint outcome of qualitatively different “impulsive” (or associative) and “reflective” processes. There are important individual differences regarding both types of processes, and the relative strength of both in a specific situation is influenced by prior behavior and state variables (e.g., fatigue, alcohol use). From this perspective, a specific behavior (e.g., alcohol misuse) can be predicted by the combined indices of the behavior-related impulsive processes (e.g., associations with alcohol), and reflective processes, including the ability to …
The Effects Of Caffeine On Delay Discounting In Humans, Andrew Dylan Markham
The Effects Of Caffeine On Delay Discounting In Humans, Andrew Dylan Markham
Masters Theses, 2010-2019
A behavioral form of impulsivity, delay discounting, has been used to examine the effects of drug consumption on individuals' abilities to delay gratification. However, delay discounting has not been used to examine one of the most commonly used drugs in the world, caffeine. Nor has delay discounting been used to examine the effects of drug influence on impulsivity. This study examined the influence of 200 mg caffeine on delay discounting in a collegiate sample. 15 participants underwent two experimental sessions: a caffeine condition and a placebo condition. Although participants were more impulsive under caffeine than under placebo, this trend was …
Using An Adjusting Amount Procedure To Investigate Impulsivity In Spontaneously Hypertensive Rats (Shr), Phillip Andrew Halsey
Using An Adjusting Amount Procedure To Investigate Impulsivity In Spontaneously Hypertensive Rats (Shr), Phillip Andrew Halsey
Masters Theses, 2010-2019
This experiment compared impulsivity in spontaneously hypertensive rats (SHRs), a putative animal model of Attention Deficit/Hyperactivity Disorder (ADHD), with two control strains. One definition of impulsive behavior that appears in the literature is preference for smaller sooner (SS) reinforcers over larger later (LL) reinforcers when both are concurrently available in the context of discrete trial choice procedures. Adopting that definition, the current experiment used an adjusting amount procedure to measure changes in the subjective value of delayed reinforcers. The LL reinforcers varied across 5 conditions (5 pellets, each evaluated at 5 delays: 2, 4, 8, 16, and 32-s). From the …
Contextual Influences On Associations Between Impulsivity And Risk-Taking And Child Delinquency, Michael L. Vitulano
Contextual Influences On Associations Between Impulsivity And Risk-Taking And Child Delinquency, Michael L. Vitulano
Masters Theses
Previous literature has shown that risk factors for delinquency include individual characteristics of impulsivity and risk-taking as well as contextual influences such as neighborhoods, parenting and engagement in physical activity (e.g., exercise, sports). Theory suggests that individual characteristics interact with contextual factors to influence child development, however evidence is limited. The current study examined the interaction between these individual and contextual risks to influence childhood delinquency in a community sample of 89 children ranging from 9 to 12 years of age (M = 10.4, SD = 1.1). Questionnaire measures showed that both caregiver report of impulsivity and self-reported risk-taking were …
A Review Of Petry & Madden’S Chapter Discounting And Pathologicalgambling In Impulsivity: The Behavioral And Neurologicalscience Of Discounting, Becky L. Nastally
A Review Of Petry & Madden’S Chapter Discounting And Pathologicalgambling In Impulsivity: The Behavioral And Neurologicalscience Of Discounting, Becky L. Nastally
Analysis of Gambling Behavior
Petry and Madden contribute a revealing chapter on the relationship between discounting and pathological gambling to Madden and Bickel’s (2010) Impulsivity: The Behavioral and Neurological Science of Discounting. Within the chapter, the authors note the increased interest in the topic of delay discounting and gambling while presenting some obscurities in the existing body of literature further research will need to address, including the co-occurring role of substance abuse in pathological gamblers. Additionally, the chapter outlines theoretical interpretations of discounting as they relate to gambling behavior as well as highlights the need for further research in the area of probability discounting …
Does Disinhibition Mediate Alcohol Use And Risk Taking?, Brian J. Klassen
Does Disinhibition Mediate Alcohol Use And Risk Taking?, Brian J. Klassen
Wayne State University Theses
The relationship between alcohol use and risk-taking is well-documented in the psychological literature. Although this area has attracted an enormous amount of research and interest, the mechanisms that underlie this relationship are not well understood. A model whereby executive functioning (disinhibition, specifically) mediated the relationship between alcohol use and risk-taking/impulsivity was proposed and tested. Although alcohol use and self-reported impulsivity were related on a number of different measures, alcohol use was largely not related to disinhibition, nor was disinhibition related to impulsivity/risk-taking. Therefore, full-fledged tests of mediation could not be performed. Study limitations and directions for future research were also …
