Aims: To investigate the developmental trajectory of the rate and perceptual assessment of oral diadochokinesis (DDK) in typically developing children compared with adults. Also to examine the characteristics of DDK productions in children with speech sound disorders (SSD) and the relationship between DDK production and percentage of consonants…

Graphotactic as well as phonological factors influence native English speakers' decisions about consonant doubling in the spelling of nonwords, e.g., "zimen" versus "zimmen." This study examined the extent to which such influences apply to non-native speakers of English, who presumably have less knowledge of English…

This dissertation examines the development of the internal structure of the Korean syllable by adult Korean learners whose native language is English. Prior research has identified the prominence of the body constituent in Korean and the rime constituent in English. The current study focuses on the acquisition of the body unit by English speakers…

This study investigates whether a natural order exists for non-native acquisition in the production of English syllable coda obstruents by Korean and Chinese adult native speakers. We recorded L2 English monosyllabic words produced by 66 Chinese and 51 Korean native speakers. The recorded speech was then evaluated by 11 native-speaker listeners of…

This dissertation examines the influence of L2 orthographic representation on the phonological development of American English speakers learning Korean, addressing specifically the syllabification and resyllabification of Korean intervocalic obstruents and the intervocalic liquid phoneme. Although Korean and English both employ alphabetic writing…

The present study examined the relations of maternal literate support instructions during parent--child joint writing to children's word reading and writing across 1 year among 95 4- and 5-year-old children from Korea. The whole episode of mothers individually teaching their children how to write words was videotaped, and a Korean scale of…

This study investigated (1) the role of syllable awareness in word reading and spelling after accounting for the effects of print-related skills (letter-name and letter-sound knowledge, and rapid serial naming), and (2) unique contributions of orthographic, semantic (vocabulary and morphological awareness), phonological, and print-related…

Recent literature has sought to understand the presence of epenthetic vowels after the productions of postvocalic word-final consonants by second language (L2) learners whose first languages (L1s) restrict the presence of obstruents in coda position. Previous models include those in which epenthesis is seen as a strategy to mitigate the effects of…

When two consonants within an English word were transposed to create a nonword, difficulty in lexical decision responses to that nonword was revealed, most strongly when the coda of the first syllable was exchanged with the onset of the second (e.g., "nakpin" derived from "napkin"), but also when onsets were exchanged between syllables (e.g.,…

This study examined the relative contribution of letter-name knowledge and phonological awareness to literacy skills and the relationship between letter-name knowledge and phonological awareness, using data from Korean-speaking preschoolers. The results revealed that although both letter-name knowledge and phonological awareness made unique…

This dissertation addresses the extent to which linguistic behavior can be described in terms of the projection of patterns from existing lexical items, through an investigation of Korean reduplication. Korean has a productive pattern of reduplication in which a consonant is inserted in a vowel-initial base, illustrated by forms such as "alok"--"t…

This study examined the development of Korean consonant-vowel (CV) syllable identification, consonant and vowel letter knowledge, and their relationships to phonological awareness and the reading of regular Hangul words among Korean kindergartners as a 6-month longitudinal study. Results showed that Korean children identified CV syllables better…

This study investigated trajectories of Korean children's growth in the awareness of four phonological units--"syllable," "body," "rime" and "phoneme"--over time, by following a sample of 215 children over a period of 15 months, beginning at their first year of preschool and collecting four waves of data. Much of the existing research suggests…

To segment continuous speech into its component words, listeners make use of language rhythm; because rhythm differs across languages, so do the segmentation procedures which listeners use. For each of stress-, syllable-and mora-based rhythmic structure, perceptual experiments have led to the discovery of corresponding segmentation procedures. In…

Are the visual word-processing tasks of naming and lexical decision sensitive to systematic phonological properties that may or may not be specified in the spelling? Two experiments with Hangul, the alphabetic orthography of Korea, were directed at the effects of the phonological process of assimilation whereby one articulation changes to conform…
