Investigation Of A Misophonia And Fluid Intelligence Relationship: Sound Spectrum Variation Impact On Fluid Intelligence Task Responses, Leslie Watson

Master's Theses

ABSTRACT Studies of misophonia have not assessed the impact of music and sound complexity on intelligence in individuals with misophonia. Edelstein et al. (2013) have provided work which pools trigger sound characteristics including sound repetitiveness yet does not include a substantial music subcategory. Utilizing the Cattell–Horn–Carroll model of intelligence, the current study explores the nature of music and music complexity on fluid intelligence, as described by Sternberg (2012). The hypotheses for this study focused on the relationship that complexity and music might have with misophonia. The rate of misophonia in the Mechanical Turk population was hypothesized to be 20%. The …

Relationships Between Age And White Matter Integrity In Children With Phenylketonuria, Erika M. Wesonga

Arts & Sciences Electronic Theses and Dissertations

Objective: Phenylketonuria (PKU) is a hereditary metabolic disorder associated with cognitive compromise. Diffusion tensor imaging (DTI) has allowed detection of poorer microstructural white matter integrity in children with PKU, with decreased mean diffusivity (MD) in comparison with healthy children. However, very little research has been conducted to examine the trajectory of white matter development in this population. The present study investigated potential differences in the developmental trajectory of MD between children with early- and continuously-treated PKU and healthy children across a range of brain regions.

Methods: Children with PKU (n = 31, mean age = 12.2 years) were …
