Habit Formation In Active Avoidance, Kelsey J. Burke
Habit Formation In Active Avoidance, Kelsey J. Burke
Theses and Dissertations
Two studies explored feedback value in avoidance learning using rats. We show that limited, but not extended trained rats were sensitive to feedback devaluation via counterconditioning. Identical effects on motivational transfer were obtained. These results suggest that maladaptive avoidance may be established in a similar way to habits of consumption.

Individuals with obsessive-compulsive disorder often identify psychosocial stress as a factor that exacerbates their symptoms, and many trace the onset of symptoms to a stressful period of life or a discrete traumatic incident. However, the pathophysiological relationship between stress and obsessive-compulsive disorder remains poorly characterized: it is unclear whether trauma or stress is an independent cause of obsessive-compulsive disorder symptoms, a triggering factor that interacts with a preexisting diathesis, or simply a nonspecific factor that can exacerbate obsessive-compulsive disorder along with other aspects of psychiatric symptomatology. Nonetheless, preclinical research has demonstrated that stress has conspicuous effects on corticostriatal and limbic …

Suppression is a useful everyday skill leading to the clinically important outcome of forgetting. Suppression-induced forgetting, investigated with the think/no-think (TNT) paradigm, is typically demonstrated on direct tests of memory, even though indirect tests are often more ecologically valid. We report results from two TNT experiments terminating in indirect tests—tests that seem not to measure memory. For a subset of the participants in Experiment 1, latencies to rate word valence were delayed by flankers previously learned but not by flankers previously learned and then suppressed on 16 occasions. For a similar subset in Experiment 2, cue meaning denoted by free …
Examining The Roles Of Sex, Methamphetamine, And Degree Of Training In Habit Formation In Rats, Hannah Schoenberg
Examining The Roles Of Sex, Methamphetamine, And Degree Of Training In Habit Formation In Rats, Hannah Schoenberg
Graduate College Dissertations and Theses
Addiction is characterized by a progressive loss of executive control over drug-seeking and consumption, and may be associated with a behavioral shift from instrumental goal-directed actions to stimulus-response habits. Sex differences in drug addiction have been linked to changing hormone levels across the estrous cycle, and females exhibit a particular vulnerability to psychostimulants such as cocaine and amphetamines. Psychostimulants and estrogen both influence dopaminergic activity in the dorsal striatum, a region of the brain in which dopamine activity is thought to mediate the shift from action to habit. In the present set of experiments, we examined the roles of sex, …
