Word Recognition In The Parafovea: An Eye Movement Investigation Of Chinese Reading, Jinmian Yang

Doctoral Dissertations 1896 - February 2014

Chinese is a logographic writing system that drastically differs from alphabetic scripts in many important aspects. Thus, the nature of parafoveal processing in reading Chinese may be different from that in reading alphabetic languages. Here, four eye-tracking experiments using the boundary display change paradigm (Rayner, 1975) were conducted to explore the role of high level information, like semantic and plausibility information, in the parafovea for Chinese readers.

Experiments 1 and 2 used two-character words that can have the order of their component characters reversed, and still be lexical units as target words. Readers received a parafoveal preview of a target …

Modeling Source Memory Decision Bounds, Angela M. Pazzaglia

Masters Theses 1911 - February 2014

Current Signal Detection Theory models of source memory necessitate assumptions about the underlying distributions of source strengths to describe source memory performance. The current experiments applied a modified version of the same-different task in order to plot individual memory stimuli along a controlled dimension of the average frequency of voices. This technique allowed us to determine that subjects were using an independent-observations strategy rather than a differencing strategy when deciding whether two test words were spoken by the same or different female speakers at study. By including two male and two female voices and changing the task distinction from same …

Transposed Letter Effects In Prefixed Words: Implications For Morphological Decomposition, Kathleen M. Masserang

Masters Theses 1911 - February 2014

The nature of morphological decomposition in visual word recognition remains unclear regarding morphemically complex words such as prefixed words. To investigate the decomposition process, the current study examined the extent to which effects involving transposed letters are modulated when the transposed letters cross a morpheme boundary. Previous studies using masked priming have demonstrated that transposed letter effects (i.e. superior priming when the prime contains transposed letters than when it contains replacement letters) disappear or markedly decrease when the transposition occurs across a morpheme boundary. The current experiments further investigated transposed letter effects in prefixed words using both parafoveal previews in …

Understanding Occlusion Inhibition: A Study Of The Visual Processing Of Superimposed Figures, Destinee L Chambers

Doctoral Dissertations 1896 - February 2014

This study investigates a phenomenon that I have termed occlusion inhibition. This research and a small number of earlier studies suggest that, in some experimental conditions, when an attended (target) object is partially occluded by a distractor object, there is less attention allocated to the occluded region of the target object than to the visible parts of that object. In the literature, there are mixed results concerning this attentional effect. Some studies find it and others do not. This study investigates the differences between those conflicting studies with the goal of identifying the factor or factors that govern when occlusion …
