Discounting In The Pigeon: Food-Specified Conditioned Reinforcers, Matthew Wolf
Discounting In The Pigeon: Food-Specified Conditioned Reinforcers, Matthew Wolf
Masters Theses, 2010-2019
Discounting has been observed across a wide range of species, procedures, and reinforcers. One of the main differences in the literature is that studies with humans use money (conditioned reinforcer) as the reinforcer being discounted. This is in contrast to studies with non-human animals where the discounted outcomes are usually directly consumable like food and water (primary reinforcers). At present, there is no non-human animal equivalent to money that has been identified in the discounting literature. To further bridge the remaining gaps in the methodology, a common currency is needed to study conditioned reinforcers in the discounting paradigm. An adjusting-amount …
Attentional Processing: Replication And Extension Of Selection Bias As A Predictor Of Intertemporal Choice Behavior, Dylan Rutter
Attentional Processing: Replication And Extension Of Selection Bias As A Predictor Of Intertemporal Choice Behavior, Dylan Rutter
Masters Theses, 2010-2019
Basic underlying mechanisms of discounting delayed rewards remain unclear (Green & Myerson, 2013). There has been evidence that attentional mechanisms (e.g., fixation and fixation duration) could be further investigate processes related to the discounting of delayed rewards (Franco-Watkins, Matteson, & Jackson, 2016). Franco-Watkins et al. (2016) was the first to propose a measure of attentional mechanisms in a discounting paradigm, known as selection bias. The authors found selection bias was positively correlated with choice behavior. The present study replicated selection bias using a titration procedure and Area Under the Curve scores. This study also analyzed selection bias across choice presentations …
Examining The Effects Of D-Amphetamine On Discounting In Spontaneously Hypertensive Rats (Shr), Daniel Joseph Peterson
Examining The Effects Of D-Amphetamine On Discounting In Spontaneously Hypertensive Rats (Shr), Daniel Joseph Peterson
Masters Theses, 2010-2019
This experiment examined d-amphetamine’s effect on discounting of delayed and probabilistic outcomes in spontaneously hypertensive rats (SHRs), a purported animal model of Attention Deficit/Hyperactivity Disorder (ADHD), with two control strains. Stimulants such as d-amphetamine are commonly administered in humans diagnosed with ADHD, thus resulting in increases in self-controlled responding on delay tasks. However, very little has been done examining the effects of d-amphetamine on delay tasks using the SHR strain, a purported animal model of ADHD. Recent research has also suggested that responses on delay and probability discounting procedures are mediated by the same underlying mechanism in animal models (Green, …
