Linguistic performance as a function of abstract task demands in children with spina bifida.

Children with spina bifida and hydrocephalus (SBH) have been observed to have deficits in discourse, characterized by a high frequency of irrelevant utterances and poorer performance with abstract than concrete language. The Preschool Language Assessment Instrument (PLAI) was used to compare children with SBH and language-age controls on discourse skills at four levels of abstraction. In addition, a qualitative assessment of differences in types of inadequate productions was conducted. Children with SBH performed comparably to controls on concrete levels of the PLAI, but they produced significantly more 'no response' and irrelevant responses than the controls.

Distractibility and vocabulary deficits in children with spina bifida and hydrocephalus.

This experiment tested the hypothesis that children with spina bifida and hydrocephalus (SBH) are more distractible than normal children, and that the distractibility partially accounts for the language deficits of these children. In Part 1, 15 of these children of primary-school age were compared with controls matched for mental age on a non-verbal task during which irrelevant stimuli were present or absent. Interference effects of the irrelevant stimuli were larger and more persistent for the SBH children. In Part 2, the children and their controls were tested for comprehension of relational words, with and without irrelevant information. The two groups performed similarly when there was no irrelevant information, but the SBH children exhibited vocabulary deficiencies when irrelevant items were present. These findings support the original hypothesis of a relationship between distractibility and language deficits.

A program for achieving generalization of grammatical rules to spontaneous discourse.

Four language-disordered children were presented with a 4-step program designed to achieve generalization of target grammatical rules to spontaneous discourse. A multiple baseline design was used to compare trained and untrained rule usage. During each step of the program, the clinician arranged for the child's own intentions to evoke the target rule. Progression through the program entailed systematically increasing the number of nontarget events the child needed to convey, and decreasing the frequency with which the clinician modelled the target. Trained target rules increased in frequency while untrained rules did not. When therapy was then initiated on the untrained rules, they also increased in frequency while the first rules continued to be produced at mastery level.

The relationship between perceptual dysfunction and language disorders: a case report.

The acquisition of language is discussed in relation to two specific perceptual processes: first, identification and discrimination of recurring aspects of an experience, and second, integration of the language form with the specific aspect of the event being represented. The analysis of the language of a child with perceptual and integrative deficits revealed expressive use of language without comprehension and limited knowledge of concepts. Explanations of these behaviors are presented in light of the child's perceptual and integrative dysfunctions. Implications for clinical management of a perceptually based language disorder are discussed.
