Statistical Bootstrapping Of Speech Segmentation Cues, Nicolas O. Planet
Masters Theses 1911 - February 2014
Various infant studies suggest that statistical regularities in the speech stream (e.g. transitional probabilities) are one of the first speech segmentation cues available. Statistical learning may serve as a mechanism for learning various language specific segmentation cues (e.g. stress segmentation by English speakers). To test this possibility we exposed adults to an artificial language in which all words had a novel acoustic cue on the final syllable. Subjects were presented with a continuous stream of synthesized speech in which the words were repeated in random order. Subjects were then given a new set of words to see if they had …
Modeling Source Memory Decision Bounds, Angela M. Pazzaglia
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 …
