The integrity of phonological representation/processing in dyslexic children was explored with a gating task in which children listened to successively longer segments (gates) of a word. At each gate, the task was to decide what the entire word was. Responses were scored for overall accuracy as well as the children's sensitivity to coarticulation…

The relations among articulation accuracy, speech perception, and phoneme awareness were examined in a sample of 97 typically developing children ages 48 to 66 months. Of these 97 children, 46 were assessed twice at ages 4 and 5 years. Children completed two tasks for each of the three skills, assessing these abilities for the target phoneme /r/…

Twenty-one normally developing 3-year-old children were tested on two approximate consonant contrasts, "rake-lake" and "wake-rake," and a control contrast, "wake-bake." The children showed very accurate perceptions of minimal pairs. Children who did not yet articulate "r" or "l" appropriately showed somewhat less consistent perception than…

Examined performance of over one hundred 6- to 10-year olds on three of each of the following tasks: processing speed, memory span, phonological skill, and articulation tasks assessing speed with which they could say familiar stimuli. Found that performance on span tasks was predicted by phonology and articulation tasks but not by age or…

Explored mechanisms responsible for improvements in short-term memory in early to middle childhood. Recall and speech rate for acoustically similar and dissimilar words and words of differing lengths were assessed in three groups of children of 4 to 10 years. (RH)

A series of three experiments examined children's sensitivity to probabilistic phonotactic structure as reflected in the relative frequencies with which speech sounds occur and co-occur in American English. Children, ages 2-1/2 and 3-1/2 years, participated in a nonword repetition task that examined their sensitivity to the frequency of individual…

Examines the effects of word duration on memory span in subjects of different ages. Concludes that developmental increases in short-term memory span can be explained in terms of increases in speech rate. Suggests that increases in speech rate with age reflect increases in the speed of articulation of individual words. (Author/AS)

The objective of this research was to explore whether orthographic learning occurs as a result of phonological recoding, as expected from the self-teaching hypothesis. The participants were 32 fourth- and fifth-graders (mean age = 10 years 0 months, SD = 7 months) who performed lexical decisions for monosyllabic real words and pseudowords under…

Examined the effects of rounded and unrounded vowels on the perception of the voiceless fricatives "s" and "sh" by adults and by young children who could and could not produce both sounds. Concluded that productive mastery is not critically responsible for perception of the distinction between the two phonemes or the…

Examined articulation and interarticulation (pause) times on Rapid Automatized Naming Tests for first- and second-graders. Found that pause and articulation times for RAN letters and objects were not reliably related, compared to RAN numbers articulation and pause durations. Subtest pause durations were differentially related to reading. RAN…

This article explores young children's facility in phonological awareness tasks requiring either the detection or the articulation of head, coda, onset, and rime subsyllabic units shared in word pairs. Data are reported from 70 nonreading children and 21 precocious readers attending preschools. Prereading children were able to articulate shared…

Results of this experiment suggest that pronunciation has a unique effect on discrimination learning, and that the magnitude of this effect (relative to control performance) varies as a function of the type of materials used and the age of Ss. (Authors)

Compared speaking rates, digit span, and speech timing in profoundly deaf 8- and 9-year-olds with cochlear implants and normal-hearing children. Found that deaf children displayed longer sentence durations and pauses during recall and shorter digit spans than normal-hearing children. Articulation rates strongly correlated with immediate memory…

List repetitions in lists with phonologically similar and dissimilar items were used to examine improvement in preschool children's recall. Cumulative repetition caused a moderate increase in memory span and the phonological similarity effect. Repeated serial order information was helpful for children's recall, but articulatory coding was not. (BC)

Results of three experiments indicate that the developmental increase in memory span cannot be explained by differences in identification time or by the hypothesis that articulation time is the sole or major cause for the increase. It is argued that the development of memory span with age depends on a combination of factors. (BC)
