Syntax And Semantics Of Perceptual Representation, James K. Quilty-Dunn
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 …
Spatial-Relational Learning And Memory Deficits Associated With Nmdar Autoantibodies In Systemic Lupus Erythematosus, Brittany L. Bascetta
Spatial-Relational Learning And Memory Deficits Associated With Nmdar Autoantibodies In Systemic Lupus Erythematosus, Brittany L. Bascetta
Dissertations, Theses, and Capstone Projects
Individuals with Systemic Lupus Erythematosus (SLE) experience inflammation that may target any organ within the body, including the central and peripheral nervous systems. Additionally, these individuals often demonstrate psychological dysfunctions including emotional and cognitive deficits; however, research is inconsistent as to the nature and cause of these dysfunctions. While there are multiple factors that may increase risk for variability in cognitive function, such as population differences, socioeconomic status (SES), mood disorders (depression and anxiety), medication effects, and disease activity, these factors do not reliably predict the severity and extent of cognitive deficits. A growing body of animal research associates autoantibodies …
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).
