Natural language contains many examples of sound-symbolism, where the form of the word carries information about its meaning. Such systematicity is more prevalent in the words children acquire first, but arbitrariness dominates during later vocabulary development. Furthermore, systematicity appears to promote learning category distinctions, which…

Purpose: The purpose of this study was to investigate the psychophysical boundary used for categorization of voiced-voiceless stop consonants in native Japanese speakers. Method: Twelve native Japanese speakers participated in the experiment. The stimuli were synthetic stop consonant-vowel stimuli varying in voice onset time (VOT) with…

Reading is a complex process that includes the integration of information about letters (graphemes) and sounds (phonemes). In many circumstances, such as noisy environments, response inhibition is an additional factor that plays a marked role in successful oral reading. Response inhibition can take the form of task relevant inhibition (i.e., foils…

An early skill in learning to read has as much to do with hearing how words sound as it does with seeing how words are written. Phonological awareness involves being able to recognize and manipulate the sounds within words. Learning to identify the sounds in words through instruction happens best when the sounds are explicitly connected to the…

Veteran teacher Rachel Harbison used vivid stories to involve kindergartners in sociodramatic play to motivate reading acquisition. Children learned through staged events that a mischievous Word Queen had planted "tricks" in the alphabet (i.e., the irregularities in English spelling) to prevent children from learning to read. The…

Speech disorders occur commonly in individuals with Down syndrome (DS), although data regarding the auditory-perceptual speech features are limited. This descriptive study assessed 47 perceptual speech features during connected speech samples in 26 children with DS. The most severely affected speech features were: naturalness, imprecise…

Purpose: Studies of infants' early vocalizations have proven helpful in describing the developmental characteristics of various communication disorders. However, few studies have addressed the early vocalizations of infants and toddlers who were later diagnosed, as older children, with childhood apraxia of speech (CAS). We refer to these infants…

People prefer words with consonant articulation locations moving inward, from the front to the back of the mouth (e.g., "menika"), over words with consonant articulation locations moving outward, from the back to the front of the mouth (e.g., "kemina"). Here, we modulated this "in-out effect" by increasing the fluency…

Phonological awareness may be influenced by differences in the characteristics of the items studied. This hypothesis is considered particularly applicable to Arabic, which is a diglossic language. This study examined the impact of phonemic position and the affiliation of the items between spoken and standard languages on phonemic isolation tasks.…

This study investigated the hypothesis that academic vocabulary instruction infused with morphological analysis of bound Latin roots-such as analysis of the relation between innovative and its bound root, nov (meaning "new")-will enhance word learning outcomes for English Learner (EL) adolescents. Latinate words with bound roots comprise…

Emerging evidence suggests domain-general processes, including working memory, may contribute to reduced speech production skills in young children. This study compared the phonological short-term (pSTM) and phonological working memory (pWM) abilities of 50 monolingual English-speaking children between 3;6 and 5;11 with typical speech production…

This study investigated the hypothesis that academic vocabulary instruction infused with morphological analysis of bound Latin roots--such as analysis of the relation between innovative and its bound root, nov (meaning "new")--will enhance word learning outcomes for English Learner (EL) adolescents. Latinate words with bound roots…

The acquisition of literacy skills is a complex and multi-faceted process that begins long before typical school-based literacy instruction. The present study sought to examine and expand research regarding the independent and interactive contributions of neuropsychological development, movement, play, and music on the development of literacy…

Vowel nasalization usually occurs through a two-step process whereby a vowel is nasalized via coarticulation with a nearby nasal segment; when the language later drops the nasal segment, a nasal vowel remains. Spontaneous vowel nasalization is a rare, peculiar form of nasalization that emerges in contexts that lack an historical etymological nasal…

Children with autism spectrum disorders have been reported to be less influenced by a speaker's face during speech perception than those with typically development. To more closely examine these reported differences, a novel visual phonemic restoration paradigm was used to assess neural signatures (event-related potentials [ERPs]) of audiovisual…
