Thirty children (aged 4-10) and 10 adults repeated 2 target syllables, which were analyzed acoustically to evaluate development of identification and discrimination in children for the vowel duration cue to final consonant voicing. Results showed that category boundary, category separation, response consistency, and perceptual consistency…

The study demonstrated that 36 male children (ages 7-10) with learning problems were characterized not by a restricted vocabulary as such (i.e., the variance common to both receptive and productive vocabulary measures) but by a hampered production of words (i.e., the variance common to both speed-of-naming and productive vocabulary measures.…

This study found that 30 children with reading disability (RD) performed more poorly than 30 children with normal reading achievement on tasks of serial rapid naming, verbal fluency, letter-based word retrieval, and articulatory speed. RD children had significantly longer reaction times and production durations on the serial naming task. Findings…

The Iowa Articulation Norms Project and its Nebraska replication provided normative information about speech sound acquisition of children ages two through nine. This paper discusses the influence of demographic variables, trends in ages of acquisition, the impact of acceptability criteria on outcomes, and the usefulness of plotting acquisition…

Cognitive, behavior, achievement, and English/French speaking skills were correlated with ratings of oral French ability for third-grade francophone and anglophone immersion students. Teacher ratings correlated with achievement and cooperativeness, but independent ratings didn't. Objective evaluation procedures should be developed to minimize the…
