The Mediating Role Of Receptive Language In The Relationship Between Verbal Memory And Language Production In Preschool Children, Anjali Vandrie

Psychology Theses

Research has demonstrated a close relationship between verbal short-term (STM) and working memory (WM) and receptive language in children (Baddeley, Gathercole, & Papagno, 1998; Ellis & Sinclair, 1996). Few studies have examined the relationship between memory and language production, and these studies focus on STM only. Though correlations have been found between verbal STM and production, the nature of the correlations are unclear. The current study examined the possibility that receptive language mediates the relationship between memory and language production. Children between 3;0 and 5;11 were administered tests assessing receptive vocabulary, receptive grammar, expressive vocabulary, verbal STM, and verbal WM. …

Development Of Visual-Verbal Integration In Working Memory During Childhood And Its Relation To Language And Reading, M. Katrina Smith

Psychology Dissertations

Research has demonstrated working memory improves during childhood and supports vocabulary, grammar, and reading development (Adams & Gathercole, 1995, 1996; Bowey, 1996; Gathercole & Baddeley, 1989, 1990). Prior to the addition of the episodic buffer in Baddeley’s model of working memory (2000a), auditory and visual aspects of working memory were often treated separately without evaluating contributions from the ability to integrate the two forms of information. The present study was designed to investigate the development of visual-verbal integration in working memory and its role in language and reading development. Tests of receptive vocabulary, receptive grammar, and decoding ability were administered …

Working Memory Capacity, Temporal Discounting, And Exercise Rates, Kathleen Lambourne

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During decision-making, an individual must weigh the value of the outcomes involved while also considering the amount of time until the outcomes will occur. Discounting occurs when a smaller, immediately available reward is chosen over a larger, more delayed reward. Discounting rates are likely related to working memory capacity, because working memory stores and processes the value of the outcomes. The purpose of this study was to examine the relationship between working memory, temporal discounting, and the decision to engage in physical activity.

The results showed that working memory capacity was related to the physical activity rates. Discounting rates from …

Warning Compliance: Effects Of Stress And Working Memory, Jessica Helmick-Rich

Electronic Theses and Dissertations

This study investigated the effects of cross-modality warning presentation and retention in a dual-task paradigm in a simulated military environment under various task-induced stress levels. It was also intended to determine what role working memory played in the mode of warning presentation that resulted in the highest retention and subsequent compliance. An all within participant design was created in order to determine if scores on working memory span tasks predicted performance across the varying forms of warning presentation. Furthermore, task-induced stress levels were varied over the course of the experiment to identify if workload transitions affected performance. Results revealed that …
