The Roles Of Race And Empathy On Contagious Yawning, Daroon M. Jalil

Senior Honors Projects, 2010-2019

Social Psychologists often consider race to be a marker of in-group or out-group status. When looking at race, implicit bias can take forms that are more subtle than outwards racism. Two research questions were asked in this study to better understand the psychology behind racial issues. The first question was if the number of contagious yawns (CY) a person experiences depends on the race of the stimuli being viewed. Contagiously yawning more to in-group members is a phenomena seen in chimpanzees, but has not been studied in humans in a racial context. Black and white males and females were recruited …

Build-Up Effect Of Auditory Stream Segregation Using Amplitude-Modulated Narrowband Noise, Harley J. Wheeler

Senior Honors Projects, 2010-2019

Recent psychoacoustic experiments (Böckmann-Barthel et al., 2014; Deike et al., 2012) have re-examined research regarding stream segregation and the build-up effect. Stream segregation is the ability to discern auditory objects within a stream of information, such as distinguishing one voice amongst background noise or an instrument within an orchestra. Initial works examining this topic proposed that auditory information is not immediately distinguished as various streams, but rather that differences accumulate over time, allowing listeners to segregate information following a period of build-up (i.e., the build-up effect); whereas more current findings indicate a build-up period is unnecessary for segregation. This experiment’s …

Judging Laura, Rebecca E. Richardson

Senior Honors Projects, 2010-2019

Laura Audax is a sixteen-year-old girl who has an interesting set of characteristics. She is a dynamic mixture of compassion, stubbornness, brilliance, recklessness, imagination, and arrogance. The way the world understands these personality traits has transformed and evolved over time. If a girl like Laura lived in four different time periods, society would react differently to her in each era, but the overall question is how different these reactions really are. Does the definition of what makes certain personality traits “good” or “bad” change over time?

Delay And Probabilistic Discounting Of Alcoholic Beverages, Frank L. Galante

Senior Honors Projects, 2010-2019

Discounting tasks were used to determine the degree to which college undergraduates discounted delayed and probabilistic alcoholic beverages. Tasks were framed in terms of gains (i.e.,obtaining a hypothetical amount of alcohol) and losses (i.e., losing a hypothetical amount of alcohol). In all gain and loss conditions, discounting was evident and was generally well described by a hyperboloid function. Gains were discounted more steeply then losses. There were no correlations between the median delay gain discounting rates and the median delay loss discounting rates. Likewise, there were no correlations between the median probabilistic gain discounting rates and the median probabilistic loss …
