Semantic Effects In Word Recognition And Picture Naming Are Moderated By Body-Object Interaction, Lisa Ruth Van Havermaet
Semantic Effects In Word Recognition And Picture Naming Are Moderated By Body-Object Interaction, Lisa Ruth Van Havermaet
Wayne State University Dissertations
A potential embodied influence in the semantic effects of Danger and Usefulness is investigated using Body-Object Interaction (BOI). Lexical decision times are influenced by ratings of Danger and Usefulness. In a frequently-found interaction, thought to be produced by activated approach-withdraw motor responses, increasing Danger ratings produce faster responses for items with lower Usefulness ratings while producing slower responses for items with higher Usefulness ratings. BOI is used to test the embodied explanation of this interaction. The same 102 words were presented in two lexical decision experiments. In both auditory and visual lexical decision, the effects of Danger and Usefulness were …

White Matter Integrity And Age Related Differences In Reaction Time Components, Yiqin Yang
Wayne State University Dissertations
Reduced speed in information processing is a well-documented phenomenon associated with advanced aging. Age-related deterioration in white matter integrity might play a role in age-related increase in reaction time (RT). However, the association between microstructural differences in particular white matter regions or tracts with RT is unclear. Decomposing RT into parts might be a better way to understand the relationship due to multiple processes involved in RT. In a lifespan sample of 90 healthy normotensive participants, this study examined the association between RT components derived from the Ratcliff diffusion model with age related difference in DTI indices of a wide …
