Capuchin Monkeys Exercise Self-Control By Choosing Token Exchange Over An Immediate Reward, Peter G. Judge, Jennifer L. Essler
Capuchin Monkeys Exercise Self-Control By Choosing Token Exchange Over An Immediate Reward, Peter G. Judge, Jennifer L. Essler
Faculty Journal Articles
Self-control is a prerequisite for complex cognitive processes such as cooperation and planning. As such, comparative studies of self-control may help elucidate the evolutionary origin of these capacities. A variety of methods have been developed to test for self-control in non-human primates that include some variation of foregoing an immediate reward in order to gain a more favorable reward. We used a token exchange paradigm to test for self-control in capuchin monkeys (Cebus apella). Animals were trained that particular tokens could be exchanged for food items worth different values. To test for self-control, a monkey was provided with …

Auditory Imagery And The Poor-Pitch Singer, Peter Q. Pfordresher, Andrea Halpern
Faculty Journal Articles
The vocal imitation of pitch by singing requires one to plan laryngeal movements on the basis of anticipated target pitch events. This process may rely on auditory imagery, which has been shown to activate motor planning areas. As such, we hypothesized that poor-pitch singing, although not typically associated with deficient pitch perception, may be associated with deficient auditory imagery. Participants vocally imitated simple pitch sequences by singing, discriminated pitch pairs on the basis of pitch height, and completed an auditory imagery self-report questionnaire (the Bucknell Auditory Imagery Scale). The percentage of trials participants sung in tune correlated significantly with self-reports …
Identifying The Negative Stigma Associated With Having A Learning Disability, Kelsey Lisle
Identifying The Negative Stigma Associated With Having A Learning Disability, Kelsey Lisle
Honors Theses
Those with learning disabilities (LDs) can be characterized as a minority group, and like most groups of minorities they face a distinct stigma by the larger population. While there iscurrently a lack of research in understanding LD stigma, it has become increasingly important given the push for inclusive classrooms settings. In this study it was hypothesized that regardlessof a participants’ gender, when participants were given a hypothetical description of a person that included information indicating that the individual has a LD, the participants would rate that individual less favorably. Results were consistent with the hypothesis. Participants perceived the hypothetical LD …
