Short-Term Visual Deprivation, Tactile Acuity, And Haptic Solid Shape Discrimination, Charles E. Crabtree

Masters Theses & Specialist Projects

The visual cortex of human observers changes its functionality in response to visual deprivation (Boroojerdi et al., 2000). Behavioral studies have recently documented enhanced tactile abilities following a short period of visual deprivation (Facchini & Aglioti, 2003; Weisser, Stilla, Peltier, Hu, & Sathian, 2005). The current study investigated the effects of visual deprivation on two unique tactile tasks. While Facchini and Aglioti observed significant effects of visual deprivation, neither Wong, Hackeman, Hurd, and Goldreich (2011) nor Merabet et al. (2008) observed these effects. Corroborating these more recent results, no difference in grating orientation discrimination performance was observed between the sighted …

Affect Perception In Computer Mediated Communication, Rachel E. Townsend, Chris Allen

Student Research Symposium

The perception of affect influences the subjective perception of an individual’s environment (Isbell & Burns, n.d.). Accurate affect perception leads to increased resilience and positive coping mechanisms when faced with daily life stressors (Robinson, 2012). Communication technologies have revolutionized the ways in which individuals connect to one another professionally and socially (Walther, 1996). This study investigated accurate affect perception in computer mediated communication (CMC) from a multidisciplinary perspective.

Communication research posit several theories to accommodate the ways in which we communicate using CMC (J. B. Walther, 1996). Personality research has documented the correlation between the traits extraversion and neuroticism with …

Effects Of Perceptual Fluency On Reasoning And Pupil Dilation, Juan Diego Guevara Pinto

Honors College Theses

Research on perceptual disfluency has examined the effects of perceptually demanding stimuli on information processing and reasoning, suggesting that disfluent stimuli elicit slower and more effortful processing. Recent criticism of perceptual disfluency, however, suggests that the effects disfluent stimuli have on processing are marginal, and that they are mediated by individual differences. Participants completed a computerized reasoning task presented in either a fluent (i.e., easy-to-read font) or disfluent format (i.e., hard-to-read font) while pupil diameter was measured by an eye-tracker system. Pupillometry is an established reliable measure of mental activity that reflects differences in cognitive load. Results showed no performance …

What You See Is What You Forget : Alcohol Cue Exposure, Affect, And The Misinformation Effect, Camille Crocken Barnes

Legacy Theses & Dissertations (2009 - 2024)

Previous research has suggested that both alcohol cues and positive affect increase the tendency to incorporate false information into memory. This series of studies sought to determine if affect mediates the influence of alcohol cues on incorporation of false information into memory. Initially, a pilot study was completed to determine the individual differences that predict which individuals experience a heightening of positive affect following visualization exercises involving alcoholic beverages. Next, a study was conducted to determine if this affect increase from exposure to alcohol cues leads to increased acceptance of misinformation into memory. Participants' memories were tested while they were …
