Neural And Behavioral Correlates Of Planning During Vocal Motor Control, Stacey Jean Sangtian
Theses and Dissertations
Speech is a goal-directed movement developed to serve the purpose of human communication. During speech, the brain simultaneously coordinates complex motor behavior and sensory information for planning, execution and online monitoring for error correction in order to ensure accurate delivery of the vocal messages. Models of speech production and voice motor control have adapted the principles of the internal forward model to explain that speech sound production is controlled by comparison of internal predictions with sensory feedback. Growing evidence from studies conducted in speech and limb motor movement indicate that these sensory predictions and responsive commands are loaded in anticipation …

Determining The Validity Of A Web-Based, Self-Rating Checklist Assessment Of Vocabulary Knowledge, Sheida Abdi
Theses and Dissertations
The purpose of this study is to examine the validity of a web-based, self-rating checklist of vocabulary knowledge. One hundred fifty-nine participants took two norm-referenced assessments in addition to one of three conditions of a developed self-rating checklist. Each condition employed a different combination of follow-up questions (synonym generation to verify participants’ self-ratings) and feedback for student responses (whether or not synonyms are correct). Condition 1 did not provide any follow-up questions or feedback, Condition 2 included follow-up questions and feedback, and Condition 3 presented follow-up questions but no feedback. Results show that participants moderately overestimated vocabulary knowledge. Moderate-to-high statistically …
