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 …

Stress, Resilience, And Impulsivity, Kendra Clark, Adam Runyan, Carissa Philippi
Undergraduate Research Symposium
Stress is a phenomenon that everyone will experience. Stress that is unmanageable can become chronic, which is linked to various negative psychological effects (Le Fevre, Matheny, & Kolt, 2003). Although stress research often focuses on the negative long-term effects, there are times where individuals develop a trait known as resilience. Resilient individuals eventually learn how to buffer the negative effects of stress (Cicchetti, 2010), and researchers have begun investigating the positive effects of resilience on stress (Cicchetti, 2010; Kermott, Johnson, Sood, R., Jenkins, & Sood, A., 2019). Currently, few studies have been conducted to identify any additional traits that may …
Minocycline As A Treatment For Traumatic Brain Injury-Induced Impulsive And Attentional Deficits, Kristen M. Pechacek
Minocycline As A Treatment For Traumatic Brain Injury-Induced Impulsive And Attentional Deficits, Kristen M. Pechacek
Graduate Theses, Dissertations, and Problem Reports
Traumatic brain injury (TBI) impacts millions worldwide and can cause lasting psychiatric symptoms. Chronic neuroinflammation is a characteristic of post-injury pathology and is positively associated with psychiatric conditions such as ADHD and bipolar disorder. Therefore, the current study sought to treat TBI-induced impulsivity and inattention using minocycline, an antibiotic with anti-inflammatory properties. Rats were trained on the five-choice serial reaction time task (5CSRT), a measure of motor impulsivity and attention. After behavior was stable on the 5CSRT, rats received either a bilateral frontal TBI or sham procedure. Minocycline was given at either 1 h post-injury or beginning at 8 weeks …
Stress And Suicidal Behavior: A Cognitive, Behavioral, And Biological Integrative Approach, Jorge Valderrama
Stress And Suicidal Behavior: A Cognitive, Behavioral, And Biological Integrative Approach, Jorge Valderrama
Dissertations, Theses, and Capstone Projects
Suicide is one of the leading causes of death in young adults in the United States. Previous research has established distal and proximal life stress as a strong risk factor for suicidal behavior. However, how stress impacts suicidal behavior via interactive cognitive and biological mechanisms has not been thoroughly examined. The present research sought to better understand the relationship between stress and suicidal behavior via altered neurobiological functioning, maladaptive cognitions, and deficits in executive functioning. The first study found a relationship between the brooding subtype of rumination and trait impulsivity in the forms of negative urgency, lack of premeditation, and …
Individual Differences In The Dopaminergic Reward System: The Effect Of Genetic Risk On Neural Reward Sensitivity And Risky Choice, Heather E. Soder
Individual Differences In The Dopaminergic Reward System: The Effect Of Genetic Risk On Neural Reward Sensitivity And Risky Choice, Heather E. Soder
USF Tampa Graduate Theses and Dissertations
When making decisions, individuals evaluate several possible outcomes of their choice; however, some display heightened reward sensitivity, despite the potential for future negative consequences, which can lead one to make risky choices. Rewards are processed in the mesolimbic dopamine reward system, and this system is in part modulated by genetic polymorphisms that are associated with dopamine transmission. The current study tested if genetic polymorphisms that are associated with enhanced dopamine neurotransmission will be more neurally reward sensitive, score higher on self-reported impulsivity, and make riskier choices. In a sample of 85 participants, five genetic polymorphisms were genotyped and used to …
Rash Impulsiveness And Reward Sensitivity In Relation To Risky Drinking By University Students: Potential Roles Of Frontal Systems, Michael Lyvers, Helen Duff, Vanessa Basch, Mark Edwards
Rash Impulsiveness And Reward Sensitivity In Relation To Risky Drinking By University Students: Potential Roles Of Frontal Systems, Michael Lyvers, Helen Duff, Vanessa Basch, Mark Edwards
Mike Lyvers
Background: Two forms of impulsivity, rash impulsiveness and reward sensitivity, have been proposed to reflect aspects of frontal lobe functioning and promote substance use. The present study examined these two forms of impulsivity as well as frontal lobe symptoms in relation to risky drinking by university students. Methods: University undergraduates aged 18–26 years completed the Alcohol Use Disorders Identification Test (AUDIT), Barratt Impulsiveness Scale (BIS-11), Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), Frontal Systems Behavior Scale (FrSBe), and a demographics questionnaire assessing age, gender, and age of onset of weekly drinking (AOD). Results: AUDIT-defined harmful drinkers reported earlier …
