Purpose: This study describes a post hoc analysis of segmental, stress, and syllabification errors in third graders' productions of derived English words with the stress-changing suffixes "-ity" and "-ic." We investigated whether (a) derived word frequency influences error patterns, (b) stress and syllabification errors always co-occur, and (c)…

This dissertation takes a Minimalist approach to phonology, treating the phonological module as a system of abstract symbolic computation, divorced from phonetic content. I investigate the position of the phonological module within the architecture of grammar and the evolutionary scenario developed by Hauser et al. (2002a) and Fitch et al. (2005).…

During the first year of life, infants begin to have difficulties perceiving non-native vowel and consonant contrasts, thus adapting their perception to the phonetic categories of the target language. In this paper, we examine the perception of a non-segmental feature, i.e. stress. Previous research with adults has shown that speakers of French (a…

It has been widely shown that infants and adults are capable of using only prosodic information to discriminate between languages. However, it remains unclear which aspects of prosody, either rhythm or intonation, listeners attend to for language discrimination. Previous researchers have suggested that rhythm, the duration and timing of speech…

This study investigated the effects of first language prosodic transfer on the perception and production of English lexical stress and the relation between stress perception and production by second language learners. To test the effect of Thai tonal distribution rules and stress patterns on native Thai speakers' perception and production of…

This study reports an exploratory analysis of the age of arrival (AoA) effect on the production of second language (L2) prosody. Three groups of Mandarin-speaking immigrants (N = 10 in each group) with varying AoA in the United States and ten native speakers of English as controls participated in the study. All participants read a paragraph of…

Two experiments examined the nature of the phonological representations used during visual word recognition. We tested whether a minimality constraint (R. Frost, 1998) limits the complexity of early representations to a simple string of phonemes. Alternatively, readers might activate elaborated representations that include prosodic syllable…

Background: Children with specific language impairment (SLI) and dyslexia are known to have impairments in various aspects of phonology, which have been claimed to cause their language and literacy impairments. However, "phonology" encompasses a wide range of skills, and little is known about whether these phonological impairments extend to…

This study describes the realization of onset and coda clusters in a 4-year old child acquiring American English, and with a higher than usual level of unintelligible speech. It reviews previous studies that have tested cluster realization against markedness and, in particular, the sonority hypothesis. This latter predicts steep rises in sonority…

Recent studies of heritage speakers, many of whom possess incomplete knowledge of their family language, suggest that these speakers may be linguistically superior to second language (L2) learners only in phonology but not in morphosyntax. This study reexamines this claim by focusing on knowledge of clitic pronouns and word order in 24 L2 learners…

This report describes three extensions to a classification system for paediatric speech sound disorders termed the Speech Disorders Classification System (SDCS). Part I describes a classification extension to the SDCS to differentiate motor speech disorders from speech delay and to differentiate among three sub-types of motor speech disorders.…

Purpose: This study examined whether lexical frequency, semantic knowledge, or sentence context affect children's production of primary stress in derived words with stress-changing suffixes (e.g., "-ity"). Method: Thirty children (M[subscript age] = 9;1 [years;months]) produced a limited set of high-frequency (HF) and low-frequency (LF) derived…

Function (i.e., grammatical) words very frequently lack word-level stress and display phonetic reduction relative to content (i.e., lexical) words. However, word-class (function vs . content) may not be the only factor that affects phonetic realization of function words; prosodic and syntactic context can also play a significant role in…

Failure to supply inflection is common in adult L2 learners of English and agrammatic aphasics (AAs), who are known to resort to bare verb forms. Among attempts to explain the absence of inflection are competing morphological and phonological explanations. In the L2 acquisition literature, omission of inflection is explained in terms of: mapping…

This study examined the effects of lexical frequency on children's production of accurate primary stress in words derived with nonneutral English suffixes. Forty-four third-grade children participated in an elicited derived word task in which they produced high-frequency, low-frequency, and nonsense-derived words with stress-changing suffixes…
