Considerable evidence supports that close to two thirds of all fourth-grade students read at less than adequate levels on reading achievement tests and that the problem has persisted for decades. This study of 1,064 third-grade students at risk for reading failure uses path analytic techniques to measure a hypothesized model linking developmental…

Humans can pronounce a nonword (e.g., rint). Some researchers have interpreted this behavior as requiring a sequential mechanism by which a grapheme-phoneme correspondence rule is applied to each grapheme in turn. However, several parallel-distributed processing (PDP) models in English have simulated human nonword reading accuracy without a…

Letter-sound knowledge is a strong predictor of a student's ability to decode words. Approximately 50% of English words can be decoded by following a sound-symbol correspondence rule alone and an additional 36% are spelled with only one error. Many students with reading disabilities or who struggle to learn to read have difficulty with phonology,…

Background: In recent years, analyses of cleft palate speech based on phonetic transcriptions have become common. However, the results vary considerably among different studies. It cannot be excluded that differences in assessment methodology, including the recording medium, influence the results. Aims: To compare phonetic transcriptions from…

The direct influence of phonological awareness (PA) on reading outcomes has been widely demonstrated, yet PA may also exert indirect influence on reading outcomes through other cognitive variables such as morphological awareness (MA). However, PA's own development is dependent and influenced by many extraneous variables such as auditory…

Purpose: This study examined the relationship between the magnitude of neck-surface vibration (NSV[subscript Mag]; transduced with an accelerometer) and intraoral estimates of subglottal pressure (P'[subscript sg]) during variations in vocal effort at 3 intensity levels. Method: Twelve vocally healthy adults produced strings of /p?/ syllables in 3…

Previous experimental psycholinguistic studies suggested that the probabilistic phonotactics information might likely to hint the locations of word boundaries in continuous speech and hence posed an interesting solution to the empirical question on how we recognize/segment individual spoken word in speech. We investigated this issue by using…

Purpose: Some psycholinguistic theories of stuttering propose that language production operates along a different time course in adults who stutter (AWS) versus typically fluent adults (TFA). However, behavioral evidence for such a difference has been mixed. Here, the time course of semantic and phonological encoding in picture naming was compared…

Purpose: This study tested proposals that maternal verbal responses shape infant vocal development, proposals based in part on evidence that infants modified their vocalizations to match mothers' experimentally manipulated vowel or consonant-vowel responses to most (i.e., 70%-80%) infant vocalizations. We tested the proposal in ordinary rather…

In this paper, we investigate the effect of neighbourhood density (ND) on vocabulary size in a computational model of vocabulary development. A word has a high ND if there are many words phonologically similar to it. High ND words are more easily learned by infants of all abilities (e.g. Storkel, 2009; Stokes, 2014). We present a neural network…

Purpose: The purpose of this study was to examine the diagnostic accuracy of traditional measures of phonological ability developed for monolingual English-speaking children with their bilingual peers in both English and Spanish. We predicted that a composite measure, derived from a combination of English and Spanish phonological measures, would…

Interlanguage is the most fruitful issue in the field of second language acquisition. In the interlanguage phase, Indonesian learners of English tend to alternate between two forms of language features to express the same language function where a variation of language forms will be exhibited to mark the variable of linguistic function.…

The purpose of this study was to examine the effects of Build a Word-Easy Spelling with Phonics, an electronic application of the word box intervention, on the acquisition, maintenance, and generalization of letter-sound correspondences for Learners of English as an Additional Language (LEALs). A single-subject multiple probe experimental design…

This dissertation investigates Voice Onset Time (VOT), which serves as an essential property for differentiating plosive consonants in L1 and L2 Mandarin Chinese. It surveys VOT variations and demonstrates that they are affected by several phonetic and phonological properties, e.g., lexical tone, place of articulation (POA), speech rate,…

There is some evidence that reading and spelling are complementary processes. The purpose of this study was to investigate the extent to which contextualized spelling (i.e., spelling activities within the context of reading instruction) is used to support reading in first-grade core reading programs. Analysis of 75 lessons across five programs…
