Differential Neural Correlates Underlying Different Cognitive Control Strategies And Their Relationship With The Barratt Impulsiveness Scale, Carroll Bentley
Differential Neural Correlates Underlying Different Cognitive Control Strategies And Their Relationship With The Barratt Impulsiveness Scale, Carroll Bentley
Psychological Science Undergraduate Honors Theses
Impulsivity is defined as a rapid unplanned action to a stimulus, where the person does not consider the consequences of their actions (Moeller et al., 2001). Various measurement techniques exist in the study of impulsivity and include self-report, behavioral and physiological measures. This breadth of measurement techniques affords researchers the opportunity to understand what is likely a multifaceted nature of this construct. Previous literature shows mixed results between the relationship of the three measures. The present study seeks to add clarity between the three different modalities of measuring impulsivity. To address this relationship, an undergraduate sample (n = 171) completed …
The Midsession Reversal Task With Pigeons: Effects Of A Brief Delay Between Choice And Reinforcement, Megan Ashley Halloran
The Midsession Reversal Task With Pigeons: Effects Of A Brief Delay Between Choice And Reinforcement, Megan Ashley Halloran
Theses and Dissertations--Psychology
During a midsession reversal task, the session begins with a simple simultaneous discrimination in which one stimulus (S1) is correct and the alternate stimulus (S2) is incorrect (S1+/S2-). At the halfway point, the discrimination reverses and S2 becomes the correct choice (S2+/S1-). When choosing optimally, a pigeon should choose S1 until the first trial in which it is not reinforced and then shift to S2 (win-stay/lose-shift). With this task pigeons have been shown to respond suboptimally by anticipating the reversal (anticipatory errors) and continuing to choose S1 after the reversal (perseverative errors). This suboptimal behavior may result from a pigeon’s …
Chlordiazepoxide Increases Risky Choice, Devin Andrew Galdieri
Chlordiazepoxide Increases Risky Choice, Devin Andrew Galdieri
Graduate Theses, Dissertations, and Problem Reports
Probability discounting is a measure of risky choice that is correlated with maladaptive behavior and psychological disorders. Benzodiazepines are a class of drug on which relatively little risky-choice research has been conducted, particularly under conditions of chronic drug exposure. Chlordiazepoxide, a standard benzodiazepine, was administered to rats that had been trained to respond on a risky-choice task in which a choice was available between a single food pellet with 100% certainty or three food pellets with probabilities of delivery that decreased across each experimental session. During baseline, responding was sensitive to the programmed contingencies and larger-reinforcer choice decreased as the …
Alcohol-Induced Impairment Of Simulated Driving Performance And Behavioral Impulsivity In Dui Offenders, Nicholas A. Van Dyke
Alcohol-Induced Impairment Of Simulated Driving Performance And Behavioral Impulsivity In Dui Offenders, Nicholas A. Van Dyke
Theses and Dissertations--Psychology
Licensed drivers arrested for driving under the influence (DUI) of alcohol have increased rates of vehicle crashes, moving violations, traffic tickets, and contribute to an estimated 120 million occurrences of impaired driving per year (Evans, 2004; Jewett et al., 2015). Survey research on DUI offenders indicates traits of impulsivity (e.g., sensation seeking). Together, these pieces of evidence suggest that DUI offenders display patterns of impulsive action and risk-taking while driving. However, to-date DUI offenders are rarely studied in a laboratory setting, and not much is known about how they respond to a dose of alcohol. The present study examined the …
Delay Discounting And Cannabinoid Enzyme Inhibitors, Devin Andrew Galdieri
Delay Discounting And Cannabinoid Enzyme Inhibitors, Devin Andrew Galdieri
Graduate Theses, Dissertations, and Problem Reports
Delay discounting is a measure of impulsive choice that is correlated with maladaptive behavior and psychological disorders. Disruptions to serotonin and dopamine pathways can cause changes in delay discounting, as can lesions to the prefrontal cortex and nucleus accumbens. The endocannabinoid system modulates other neurotransmitter systems, including dopamine and serotonin pathways. Cannabinoid receptors type 1 are found in relatively high concentrations in the nucleus accumbens and the prefrontal cortex. These receptors are activated by endogenous cannabinoids, which are synthesized on demand and broken down by catabolic enzymes. The action of these enzymes can be inhibited by a class of drugs …
Impulsivity, Rejection Sensitivity, And Reactions To Stressors In Borderline Personality Disorder, Kathy R. Berenson, Wesley Ellen Gregory, Erin Glaser, Aliza Romirowsky, Eshkol Rafaeli, Xiao Yang, Geraldine Downey
Impulsivity, Rejection Sensitivity, And Reactions To Stressors In Borderline Personality Disorder, Kathy R. Berenson, Wesley Ellen Gregory, Erin Glaser, Aliza Romirowsky, Eshkol Rafaeli, Xiao Yang, Geraldine Downey
Psychology Faculty Publications
This research investigated baseline impulsivity, rejection sensitivity, and reactions to stressors in individuals with borderline personality disorder compared to healthy individuals and those with avoidant personality disorder . The borderline group showed greater impulsivity than the avoidant and healthy groups both in a delay-discounting task with real monetary rewards and in self-reported reactions to stressors; moreover, these findings could not be explained by co-occurring substance use disorders. Distress reactions to stressors were equally elevated in both personality disorder groups (relative to the healthy group). The borderline and avoidant groups also reported more maladaptive reactions to a stressor of an interpersonal …
The Balloon Analogue Risk Task And Behavioral Correlates In Pigeons, Aaron P. Smith
The Balloon Analogue Risk Task And Behavioral Correlates In Pigeons, Aaron P. Smith
Theses and Dissertations--Psychology
Individuals experience risk ubiquitously, but measuring risk taking is difficult. The balloon analogue risk task (BART) was developed in order to assess risk taking through having subjects press a key that accrues reward but also risk losing all reward with each press. In humans, greater responding in this task is associated with other maladaptive risk taking behaviors. The present research modeled this relationship in pigeons due to their previously shown propensity towards risk taking behavior. Experiment 1 used an unsignaled balloon task in which losing could only occur after 5 pecks. Results showed below optimal performance with greater pecks associated …
The Relationship Between Adhd And Trait Facets Of The Five-Factor Model, Todd William Bennett
The Relationship Between Adhd And Trait Facets Of The Five-Factor Model, Todd William Bennett
PCOM Psychology Dissertations
Facets of the Five-Factor Model (FFM) were examined in order to understand its interaction with Attention Deficit Hyperactivity Disorder (ADHD)-symptoms. By utilizing archival data, in a correlational design, adults between the ages of 18-66 were tested for the presence of ADHD, which was then compared with data gathered from the NEO-PI-R. Comorbid psychiatric conditions often associated with ADHD were accounted for in the design. Results partially supported the hypotheses, specifically, that altruism was inversely related to Impulsivity, as predicted. However, other findings largely did not support a relationship between other specific NEO-PI-R facets and ADHD. Other significant relationships that were …
Development Of A Brief Screening Measure For Depression And Problem Drinking, Chris Wera
Development Of A Brief Screening Measure For Depression And Problem Drinking, Chris Wera
Electronic Theses and Dissertations
This study examined the psychometric characteristics of a brief assessment measure for screening for depression and alcohol use on a college campus prior to primary care medical office visits. The measure was adapted from two widely used measures: the Patient Health Questionnaire (PHQ-4) and the Alcohol Use Disorder Identification Test (AUDIT-C). Impulsivity, which has been associated with both depression and problematic alcohol use, was also examined through additional questions. The research study investigated the psychometric properties of the PHQ-4 and the AUDIT-C, and explored if eight impulsivity items from the UPPS-P measure could enhance screening for depression and problematic alcohol …
A Rat Model Of Gambling Behavior And Its Extinction: Effects Of "Win" Probability On Choice In A Concurrent-Chains Procedure, David N. Kearns, Maria A. Gomez-Serrano
A Rat Model Of Gambling Behavior And Its Extinction: Effects Of "Win" Probability On Choice In A Concurrent-Chains Procedure, David N. Kearns, Maria A. Gomez-Serrano
Analysis of Gambling Behavior
Two experiments examined the effects of varying the probability of “wins” within a rat model of gambling. On a concurrent-chains procedure, rats could choose between a “work” lever on which a fixed 20 responses produced a food pellet or a “gamble” lever, where on some trials (“wins”) only one response was required for reinforcement while on other trials 40 responses were required. Despite the fact that the work lever was always associated with the higher overall reinforcement rate, rats frequently chose to respond on the gamble lever. The frequency with which rats chose the gamble lever varied as a function …
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 …
