Validation of language subtypes in learning disabled children.

Hypothesized that children characterized by deficits in narrative skills, relative to other language skills (e.g., syntactic and semantic), would be most at risk for general academic problems, especially in reading comprehension. Using data from a previous longitudinal study by the 1st author and J. D. McKinney (see record 1985-02522-001), different subtypes of language disability were identified in 63 6- and 7-yr-old learning disabled (LD) children. Comparison data had been obtained from 66 non-LD children matched to the LD sample on age, race, and sex. Results, obtained with hierarchical cluster analysis, indicate that 6 language subtypes were derived and that these were both internally consistent and externally valid, being differentially linked to reading and math achievement over a 3-yr period. Narrative ability was shown to be relatively important in predicting academic outcomes. The 3 subtypes showing the poorest academic outcomes had the highest relative scores in syntax and semantics.

How demonstrated comprehension can get muddled in production.

The discourse skills of 31 low-income and 30 middle-income kindergarten children (mean ages 5 yrs 2 mo and 5 yrs 4 mo) from the same classrooms were examined in 2 experiments. In each experiment a nonverbal demonstration of comprehension of the discourse material was assured before Ss were asked to express that same material verbally to another child. In Exp I, Ss were read stories that they acted out with props. When comprehension was assured they were asked to paraphrase the story to another. In Exp II, Ss were either shown or instructed verbally how to open an attractive box. When comprehension was assured they were asked to teach the "trick" to a blindfolded adult. Results from both experiments indicate that although it took the low-income Ss somewhat longer to comprehend the information, the greatest difference between the groups was in the ability to communicate information that they already knew. Low-income Ss produced less relevant information on both tasks, although this did not appear to be related to linguistic complexity or sheer output.

Referential communication and reading performance in learning disabled children over a 3-year period.

Examined the ability of 30 learning disabled (LD) and 30 non-LD (NLD) 6- and 7-yr-olds to understand a sequence of instructions, communicate the steps in a sequence to others, and rephrase their verbal messages across a 3-yr period using a referential communication task. In order to perform the puzzle-box task correctly, Ss had to execute 6 steps in an invariant sequence. After Ss demonstrated a perfect nonverbal enactment of the sequence, they were asked to communicate all information about how to open the box to a puppet. Upon completion, the puppet feigned poor memory and asked the Ss to explain the step-by-step process again. Subsequently, the puppet requested that Ss rephrase their explanation of each step by either a verbal or nonverbal rephrase request. Results reveal that LD children differed from NLD peers consistently on referential communication over the 3-yr period in terms of listener competence and speaker competence. For LD Ss, the ability to produce competent verbal messages was highly related to reading comprehension both concurrently and 3 yrs later. By the 3rd yr, NLD Ss were better able to rephrase information, indicating a growing awareness of the speaker's responsibility in communication. Findings suggest that the communication measures studied play very different roles for LD and NLD Ss with regard to reading achievement.

The effects of otitis media on the attention skills of day-care-attending toddlers.

The purpose of this study was to try to understand whether otitis media (OM) affected toddlers' attention to language. The children in the sample were seen in their day care at 12 or 18 mo of age in a book-reading task when they had OM and when they were well. Children's hearing was evaluated and they were given the Sequenced Inventory of Communication Development at 24 mo of age. Over half of the sample could be classified as having chronic OM (about 5 mo per year). Half of the children were in high-quality and half in low-quality day care. Results suggested that children with chronic OM in low-quality care showed the most negative effects on attention during episodes of otitis, with the children with chronic OM displaying less attention during book reading and twice as often off-task in comparison with the nonchronic children. Mothers rated children with chronic OM as more distractible and nonattentive. Language differences did not emerge among the groups. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
