An Attempt To Increase Intelligence With Intensive Computerized Cognitive Training And Speech Therapy: A Single-Case Study

Studies have shown that individuals with Down syndrome (DS) have difficulties with speech and working memory (WM). These findings have been used to develop an intervention based on computerized cognitive training (CCT) which targets cognitive skills, such as working memory, conceptual reasoning, attention, and speech therapy (ST) which targets the components of speech and language, such as oral motor skill and speech comprehension. Accordingly, in this study the feasibility of CCT and ST for improving intelligence scores in a 12-year-old boy with DS was investigated. The intelligence quotient of the participant was assessed before and after the 105 sessions of CCT and 75 sessions of ST. Also, the parents participated in a clinical interview. The results showed improvements in digit span and maze subtests of Wechsler intelligence scale for children (WISC-III) which indicate improvements in auditory working memory and planning, but overall IQ score was not significantly changed. Parents reported increase in math performance and attention, also reduction in rumination. This study suggests that CCT and ST are promising and efficient interventions in improving speech and cognitive skills in people with DS, but further investigation is necessary.
