Children presenting with communication difficulties are among the most commonly occurring developmental problems. They were observed to have problems with their everyday activities in all the occupational performance areas, as well as displaying behaviours that have a negative impact on their functioning. These behaviours appear similar to those described in children with sensory processing and sensory modulation difficulties. Literature indicated a possible connection between speech and language difficulties and poor sensory integration. This study used the Sensory Profile, a parent report measurement of the child’s sensory responsiveness in daily life, to investigate the sensory processing and modulation of children with Specific Language Impairment, as reflected in their behavioural and emotional responses. The study indicated that this population has specific areas of sensory processing that are unique to children with SLI and that differ significantly in their sensory responsiveness from typical children and children with other conditions like Autism and Attention Deficit Hyperactivity Disorder.

The purpose of the study was to investigate the role of linguistic competence in developmental dyslexia. This was done to determine whether there existed subgroups of dyslexics classified according to linguistic criteria. / Two groups, a control group of normal readers and an experimental group of dyslexic readers, were compased using a series of reading tasks that measured certain components of linguistic competence. / A quantitative analysis between groups revealed differences at the level of linguistic competence. A qualitative analysis of the dyslexic group revealed the existence of three subgroups: a morphological subgroup, a Cloze grammatical subgroup, and a Cloze lexical subgroup. / The study indicates a need for further research in the diagnosis of language deficits in beginning readers to prevent reading problems.

Linguistic dysfluencies known as mazes have been interpreted clinically as reflecting breakdown in language formulation. Nevertheless, the relatively limited available research has suggested that maze frequency increases with linguistic complexity and that mazes are produced more frequently by children with specific language impairment (SLI) than normal language (NL) peers. This study examined the hypothesis that greater maze production by children with SLI results from their processing limitations. Language samples of school-age children with SLI (n = 9) and NL (n = 11) were collected in contexts varying in task demands: conversation, narration and expository discourse. Both groups produced significantly more mazes in the more demanding contexts than in conversation. However, no significant group effect was noted for age-matched or MLU-matched groups. These results suggest that mazes should not be viewed primarily as an indication of processing limitations or a clinical marker for SLI, but more appropriately as a byproduct of linguistic complexity across groups.
