Syntax And Semantics Of Perceptual Representation, James K. Quilty-Dunn Sep 2017

Syntax And Semantics Of Perceptual Representation, James K. Quilty-Dunn

Dissertations, Theses, and Capstone Projects

This dissertation is a defense of perceptual pluralism, the thesis that perceptual systems deliver multiple types of representations including those used in thought. In particular, it argues that perceptual systems output iconic (i.e., image-like, analog) representations as well as discursive (i.e., language-like, digital) states. A central thesis is that perceptual representations of objects are propositional and composed of concepts. It also develops a compositional syntax of iconic representation called the coordination model, according to which icons are sets of primitive parts, each of which determines values along multiple analog feature dimensions simultaneously. The dissertation supports the conclusion that perceptual …


Social Media And Cognition, Ana C. Ruiz Pardo Aug 2017

Social Media And Cognition, Ana C. Ruiz Pardo

Electronic Thesis and Dissertation Repository

Social media is an inescapable platform for sharing media and connecting with others. This thesis investigated how social media impacts cognition; specifically, attention. Study 1 investigated typical social media usage patterns and helped gauge which SM platform was most popular. Study 1 revealed three main platforms people used most often: Facebook, Instagram, and Snapchat. Facebook was reported as the most popular social media platform. Study 2 investigated how a social media post impacts cognition. It was hypothesized that participants who posted, with the intention of provoking a reaction from their followers, on their social media prior to performing a cognitive …


Weight Stigma, Cognitions, And Disordered Eating, Sarah E. Pelfrey May 2017

Weight Stigma, Cognitions, And Disordered Eating, Sarah E. Pelfrey

Electronic Theses and Dissertations

Weight stigma experiences affect people of all weights and have many negative consequences; despite this, weight stigma is still an acceptable prejudice in our society. Research has established that weight stigma is predictive of disordered eating (DE) cognitions, which are, in turn, predictive of DE behaviors. The current study explored the unique contribution DE cognitions make to DE behaviors while controlling for other DE cognitions. The DE cognitions examined in the current study were drive for thinness, weight bias internalization, and perfectionism. The DE behaviors examined were emotional eating, restrained eating, inappropriate compensatory behaviors, and binge-eating. Weight bias internalization and …


Does Genotype Correlate With Phenotype? Evaluating Ruffed Lemur (Varecia Spp.) Color Vision Using Subject Mediated Automatic Remote Testing Apparatus (Smarta), Raymond Vagell May 2017

Does Genotype Correlate With Phenotype? Evaluating Ruffed Lemur (Varecia Spp.) Color Vision Using Subject Mediated Automatic Remote Testing Apparatus (Smarta), Raymond Vagell

Theses and Dissertations

Ruffed lemur (Varecia spp.) color vision research was conducted using a multidisciplinary approach: psychophysics, genetic analysis, technology, and animal training. The behavioral manifestation of Varecia spp. trichromacy was shown using a touchscreen apparatus (SMARTA). Trichromats performed better than dichromats when discriminating red from green (G2 = 78.10, p < 0.001).
