An Erp Investigation Of Hand-Based Bias On Visual Attention, John Philip Garza Jan 2010

An Erp Investigation Of Hand-Based Bias On Visual Attention, John Philip Garza

Electronic Theses and Dissertations

Recent behavioral studies have investigated the importance of hand and arm position in visual attentional processes. Reed et al. (2006) found facilitated (faster) detection for targets that appear in the space near the hand, relative to targets appearing on the opposite side of a monitor display. The current study aimed to explore the potential bottom-up and top-down neural sources underlying this hand-bias effect on attention with ERP. Using a standard, non-predictive visual cuing paradigm, we examined early (N1, P1) and later (P3) ERP components in response target presentations in three conditions: with the non-responding hand resting on the table (Resting), …


Phonological Memory And Broader Language Development: Longitudinal And Etiologic Relations, Robin Leonhardt Peterson Jan 2010

Phonological Memory And Broader Language Development: Longitudinal And Etiologic Relations, Robin Leonhardt Peterson

Electronic Theses and Dissertations

The current research investigated the relationship of phonological memory (PM) to vocabulary and syntax learning in school-age children with and without language disorders. Previous research has established that PM and broad oral language skills covary, but disagreement remains about the reason for this association. Opposing theoretical viewpoints emphasize the importance of either bottom-up (PM influences vocabulary and syntax acquisition) or top-down (vocabulary growth influences PM skill) factors. In three longitudinal studies, we tested competing bottom-up and top-down explanations of the PM-broad language link. Study 1 utilized a structural equation modeling approach to understand PM and broad language relations from age …
