Henry, for example, studied children with typical mild ID, with no known syndrome, and observed a reduced phonological-loop capacity and poor performance on tasks measuring Central Executive Functions. The relationship of ID and WM was also explored by many other researchers. WM was also considered to predict the intellectual performance. Many studies were subsequently conducted to find high correlations between WM and intelligence but this relationship could not be established with the STM Kane et al. They have suggested that intellectual performance may be enhanced if the individual is able to maintain more information in a temporary store and to simultaneously process it. Studies have shown the relationship between WM and intelligence, for example, Just and Carpenter (1992) in their research proposed the relationship of intellectual functioning and working memory. Research conducted in this area, support the theoretical framework of working memory within the Intellectually Disabled (ID) population, seem to have relied mostly on the principles of Baddeley’s multi-component storage and processing unit that contribute to higher order cognitive function. According to Baddeley, working memory is a system that supports temporary storage and manipulation of information required for complex cognitive tasks such as language comprehension, learning and reasoning.This definition of working memory is highly suggestive of deficits of working memory within the ID population. Working memory plays an important role in learning and hence contributes towards the development of cognitive functioning. This research was undertaken to measure verbal and visual-spatial STM/WM of children varying in range between moderate-mild-borderline intellectual disability and with no known syndrome. Studies in the past mainly focused on population with known diagnoses such as down and Williams syndromes, focusing on the implications of verbal working memory only. ![]() Previous research suggests the implications of working memory among the Intellectually Disabled (ID) population however, very few researches have used comprehensive working memory-specific instruments.
