Abstract
Purpose
The speed of information processing is known to play an important role in mental disorders; This study investigated the effect of the transcranial direct current stimulation on information processing speed in children with intellectual disabilities.
Method
An experimental design with a pretest- posttest control group was used. The study population consisted of 8- to 14-year-old children with intellectual disabilities attending special primary schools in Urmia, Iran. 36 children were randomly assigned to the experimental and control groups (18 for each group). The experimental group received 10 sessions of tDCS with anode positioned over the F3 electrode (left DLPFC) and cathode over F4 (right DLPFC) The control group did not receive any intervention. Trail Making Test (TMT) was used to assess information processing speed. Data were analyzed using MANCOVA.
Results
The results revealed that tDCS led to a significant increase in information processing speed in the experimental group compared to the control group.
Conclusion
This study demonstrates that tDCS applied to the dorsolateral prefrontal cortex (DLPFC) is effective in enhancing information processing speed in children with intellectual disabilities. These finding have important implications for the development of interventions aimed at improving cognitive functioning in children with intellectual disabilities.
期刊介绍:
Research In Developmental Disabilities is aimed at publishing original research of an interdisciplinary nature that has a direct bearing on the remediation of problems associated with developmental disabilities. Manuscripts will be solicited throughout the world. Articles will be primarily empirical studies, although an occasional position paper or review will be accepted. The aim of the journal will be to publish articles on all aspects of research with the developmentally disabled, with any methodologically sound approach being acceptable.
