Exploring The Process Of Statistical Language Learning, Nicolette B. Noonan
Electronic Thesis and Dissertation Repository
In this thesis, I investigated the process of statistical word segmentation using a combination of behavioural, clinical, and neuroimaging approaches. Prior research has largely focused on the outcome of statistical learning approaches, with little research attention paid to the process of learning. In this body of research, I sought to address this issue. In Chapter 2, I examined how domain-specific and domain-general working memory interference effects on a statistical word segmentation task. I found that when completing a concurrent visuospatial or verbal working memory task, statistical language learning was impaired. Thus, this study provided some evidence that domain-general working memory …

Spatial Memory For Isolated Arm Locations On The Radial Maze, Hayden Macdonald
Electronic Thesis and Dissertation Repository
The ability to encode and retrieve information describing spatial locations allows organisms to solve a variety of natural problems. When multiple spatial locations vary with respect to foraging, predatory or environmental factors, successfully discriminating between these locations may result in increased fitness. Although, how do the spatial relations of multiple locations affect the encoding or retrieval of spatial information? Across three radial maze experiments, I addressed how spatial configuration affects working memory for multiple locations. Specifically, I asked 1) how spatial patterns affect memory for multiple locations, 2) how spatial isolation between to-be-visited locations may affect spatial memory, and 3) …
