Effects Of Early Adolescent Exposure To D-Amphetamine In A Rodent Model Of Nicotine Reward, Eric Louis Harvey
Effects Of Early Adolescent Exposure To D-Amphetamine In A Rodent Model Of Nicotine Reward, Eric Louis Harvey
Dissertations
Previous studies with rodents have found that adolescent exposure to psychoactive drugs can alter neurophysiology and produce behavioral effects that persist into adulthood. While several studies have examined the effects of adolescent exposure to nicotine on the subsequent rewarding value of various drugs of abuse in adulthood, to date, no known studies have examined the converse of this relationship. d-Amphetamine (i.e., dextroamphetamine, ProCentra®) is a potent psychostimulant that is commonly used in the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD) in adolescents. The present study assessed the effects of adolescent exposure to d-amphetamine on the rewarding value of nicotine in …
The Influence Of Training Procedures On Generalization Performance In Scent-Detection Rats, Erin Watkins
The Influence Of Training Procedures On Generalization Performance In Scent-Detection Rats, Erin Watkins
Dissertations
The global illicit trade in tobacco products leads to an overall increase in the availability of tobacco, and this increase in tobacco availability and consumption undermines effective health, safety, and taxation policies in place to protect current and future populations. Dogs working at ports and customs have been trained to detect tobacco products and research has shown rats can detect tobacco-soaked filters (Mahoney et al., 2014). Cigarette smoking is the most common form of tobacco use, and cigarettes are the most commonly trafficked product in the illicit tobacco trade. In the current study, rats were trained to respond to filter …
Assessing The Generality Of A Bout Analysis In The Description Of Operant Behavior, J. Adam Bennett
Assessing The Generality Of A Bout Analysis In The Description Of Operant Behavior, J. Adam Bennett
Dissertations
Operant psychologists typically use response rate as a primary measure of behavior. Although response rate has proven a useful dependent measure resulting in the identification of many important behavioral regularities, many researchers have argued that the measure has significant limitations. Primarily, response rate treats all responses in the measured response class as functionally equivalent and distributed uniformly across time. This conceptualization of behavior is useful as long as all responses are affected similarly by different experimental manipulations. Research has shown, however, that certain manipulations differentially affect responses with relatively short or long interresponse times. This has led to a new …
