There is a general consensus in theories of human speech recognition that humans engage in predictive processing during online speech processing. There are also claims that predictive processing indicates the operation of a predictive coding (PC) mechanism (Rao & Ballard, 1999). Formally, PC is a generative model where top-down signals consist…

This dissertation analyzes the production and perception of lexical stress in trilinguals' first, second, and third languages (L1, L2, and L3) to evaluate how the cue-weighting transfer hypothesis applies to L3 acquisition. According to this hypothesis, acoustic cues to stress have different weights across languages, and results from both…

Since it was introduced in Forster and Davis (1984), masked priming has been widely adopted in the psycholinguistic research on visual word recognition, but there has been little consensus on its actual mechanisms, i.e. how it occurs and how it should be interpreted. This dissertation addresses two different interpretations of masked priming, one…

This dissertation consists of three studies that investigate the extent to which speakers and listeners can and do plan ahead during production and comprehension. Study 1 investigates the attentional requirements of word selection. In two dual-task experiments, subjects categorized tones and then named pictures while word selection difficulty was…

Although spoken word recognition is more fundamental to human communication than text recognition, knowledge of word-processing in auditory cortex is comparatively impoverished. This dissertation synthesizes current models of auditory cortex, models of cortical pattern recognition, models of single-word reading, results in phonetics and results in…

The purpose of this study was to determine the effectiveness of three researcher-designed experimental models of vocabulary instruction during shared storybook read alouds on kindergarten children's Tier Two target word learning and maintenance of word knowledge. The Integrated Model consisted of two readings of the same storybook, direct…

While attentional models of SLA postulate attention as crucial for learning to take place (e.g., Robinson, 1995b; Schmidt, 1990, 2001; Tomlin & Villa, 1994), the role that awareness or lack thereof plays remains debatable. Indeed, the studies that have empirically addressed the construct of unawareness reveal conflicting results (e.g.,…

This study examined the relationships between concept of word development and other early literacy measures (rhyme awareness, beginning sound awareness, alphabet knowledge, letter sound knowledge, spelling, and word recognition in isolation) using data from the PALS-K. Supporting previous research by using a much larger data set than had been used…

Ehri's developmental model of word recognition outlines early reading development that spans from the use of logos to advanced knowledge of oral and written language to read words. Henderson's developmental spelling theory presents stages of word knowledge that progress in a similar manner to Ehri's phases. The purpose of this research study was…

This program evaluation of The Instant Word Notebook was conducted by two educators who created an instructional tool to teach and assess the most frequently occurring words in written text, commonly known as Instant Words. In an effort to increase the reading scores of first and second grade students, teachers were instructed to teach Instant…
