This study analyzed spontaneous language samples of three-year-olds with a history of expressive language delay (late talkers) and age-matched controls using Dore's Conversational Acts analysis (1978) and Mean Length of Utterance (MLU; Brown, 1973). Differences were observed between groups in utterances classified as organizational device and…

The use of four types of psychological state words (physiological, emotional, desire, and cognitive) during mother-child play sessions at ages 3, 4, and 5 years was examined in 30 children diagnosed with delayed expressive language at 24-31 months and 15 age-matched comparison children with typical development.

In order to determine effects of different sequential placement of the expressive language sample during evaluation of young children referred for speech or languge handicap, 27 normal 3-year-olds were evaluated. Length, complexity, or spontaneity were not affected even when the sample was elicited immediately after formal tests requiring little…

Mean length of utterance (MLU) of 15 Down's Syndrome children, aged 2-12, was examined and found to correlate highly with chronological age despite the children's language delays, at least up to MLU 3.00. MLU also predicted complexity and diversity of bound morphemes and major syntactic structures from MLU 1.00-3.50. (Author/JDD)
