A total of 35 children - 20 with expressive specific language impairment (SLI-E) and 15 typically developing (TD) peers - were compared longitudinally from 24 to 36 months with respect to their production of syllable shapes in 10-minute spontaneous speech samples. SLI-E 24-month-olds predominantly produced earlier developing syllable shapes containing vowels, liquids, and glides. TD 24-month-olds and SLI-E 36-month-olds produced approximately the same proportion of syllable types, with the exception of consonant clusters, where TD 24 month-olds produced more than SLI-E 36-month-olds. TD children at 36 months showed the greatest use of syllable shapes containing two different consonants and consonant …
Late-Talking Toddlers: Mlu And Ipsyn Outcomes At 3;0 And 4;0, Leslie Rescorla, Katherine Dahlsgaard, Julie Roberts
Late-Talking Toddlers: Mlu And Ipsyn Outcomes At 3;0 And 4;0, Leslie Rescorla, Katherine Dahlsgaard, Julie Roberts
Psychology Faculty Research and Scholarship
Expressive language outcomes measured by MLU and the Index of Productive Syntax (IPSyn) at ages 3;0 and 4;0 were investigated in 34 late talkers with normal receptive language identified between 2;0 to 2;7 and 16 typically developing comparison children matched on age, SES, and nonverbal ability. Late talkers made greater gains than comparison children between 3;0 and 4;0 in both MLU and IPSyn raw score. However, when age-standardized x-scores were analysed, the late talkers were about 2.5 Standard deviations below comparison children on both measures at both ages. At 3;0, 41 % of the late talkers had MLUs above the …
Vocabulary Growth In Late Talkers: Lexical Development From 2;0 To 3;0, Leslie Rescorla, Jennifer Mirak, Leher Singh
Vocabulary Growth In Late Talkers: Lexical Development From 2;0 To 3;0, Leslie Rescorla, Jennifer Mirak, Leher Singh
Psychology Faculty Research and Scholarship
Vocabulary growth from 2;0 to 3;0 was studied in 28 late talkers using expressive vocabulary inventories reported bimonthly on the Language Development Survey (LDS). Group milestones were 18 words at 2;0, 89 words at 2;6, and 195 words at 3;0. A sub-group of 11 children (Group I) showed a rapid vocabulary spurt between 2;2 and 2;8, reached the 150-180 word mark by 2;6, and attained the LDS ceiling of about 300 words by 2;10. In contrast, the 17 children in Group 2 still had a mean vocabulary of fewer than 30 words at 2;6, had less of a vocabulary spurt …
