Nicotine Addiction and Impulsive Behaviour: Disentangling the Relationship
… for immediate over delayed gratification (impulsive choice) and a loss of inhibitory control (disinhibition) (Madden et al.,1997). To date, our understanding of the complex association between impulsivity and drug addiction has been hindered by the cross sectional nature of the majority of …

The neurobiological bases of compulsive eating
… eating. We first investigated impulsivity (impulsive choice and impulsive action) as a potential vulnerability factor for the development of binge and compulsive eating behavior. Impulsivity has been implicated in drug addiction as well as eating disorders and obesity, but its exact role in …

Regulation of choice behavior : an experiment investigating the hypothesis that people bundle sequences of expected rewards
… enables decision makers to self-regulate their choice behavior. Most empirical work on intertemporal choice has focused on analyzing impulsive choice. Less effort has been dedicated to explanations of how individuals manage to overcome self-defeating behavior. This thesis evaluates the theory of …

Heritable variation in reward sensitivity and impulsive cction and choice in a genetically diverse inbred mouse panel
… reward sensitivity, and reversal learning (impulsive action) or delay discounting (impulsive choice). Significant heritability for anticipatory responding within the reversal task, k-value within delay discounting, locomotor activity, and reward sensitivity was found. Reversal total trials …

Siamese Fighting Fish (Betta splendens) show self-control for access to a mirror
… subjects have shown a strong to moderate impulsive choice bias whereas studies using adult humans and non-human primates have shown a strong self-control bias. While the non-human self-control literature is rich with studies using select avian and mammalian species, there is very little …

HIGH TRAIT MOTOR IMPULSIVITY IS AN ANTECEDENT TO COCAINE-SEEKING BUT NOT OXYCODONE-SEEKING BEHAVIOR IN RODENTS
… in different forms (e.g. motor impulsivity, impulsive choice) and is associated with both cocaine use disorder and opioid use disorder. Animal models of motor impulsivity and relapse vulnerability can be reasonably matched to provide valid translational approaches to help determine whether …

Neural systems involved in delay and risk assessment in the rat
… accumbens core (AcbC) and the hippocampus (H) to choice and learning involving reinforcement that was delayed or unlikely. Animals must frequently act to influence the world even when the reinforcing outcomes of their actions are delayed. Learning with action–outcome delays is a complex problem, …

Sex differences in exercise-mediated changes in diet preference and its associated cognitive and metabolic outcomes
… a voluntary wheel running (WR) and two-diet choice model in rats. Using this paradigm, we found that the simultaneous introduction of WR and HF diet resulted in complete HF diet avoidance in WR rats whereas sedentary (Sed) rats maintained HF diet preference. There is also a sex difference in …

Determinants of risky decision-making: What is peer influence?
Impulsive and risky decision-making have been linked to dangerous driving, substance use, gambling, overspending, and general delinquency. The aim of the series of studies presented in this thesis was to gain an understanding into contextual factors that influence decision-making, focusing on the …

Effects of PCBs and PBDEs on response inhibition and dopaminergic signaling
… PCB exposure has been associated with impulsive behavior in laboratory species and human cohorts, while little is known about whether PBDEs have similar effects. Both PCBs and PBDEs have been shown to perturb dopaminergic neurotransmission. The behavioral and neurochemical effects of …

Repeated amphetamine exposure and the enduring consequences on behavioral and neural plasticity
… between behavioral sensitization and impulsive choice behavior (operant delay-discounting) was examined in rats that received prior, repeated AMPH treatment. Chronic exposure to AMPH did not cause rats to become more impulsive. However, long-lasting changes in AMPH-induced locomotor …
