Abstract

Deficits in written language involving spelling can have negative effects on a person’s education and occupation. Conventional spelling therapy is a time consuming and cost-prohibitive option, if even available, highlighting the need for improved methods for remediation. One possible way to address this need may be through the use of transcranial direct current stimulation (tDCS). This study sought to examine the effects of tDCS on performance during spelling, word detection, and facial recognition tasks. Active or sham tDCS was randomly assigned to typically functioning adults. The anode electrode was placed over Broca’s area (F7 in the 10/20 EEG system) and the cathode was positioned over the upper right arm. Outcome was assessed before, during, immediately after tDCS, and again 3-5 days after tDCS. Data was analyzed using analysis of variance (ANOVA) to examine if group differences existed. Significant differences were found between active and sham tDCS on both the spelling and word-search tests. There was no significant difference between active and sham tDCS on either of the facial recognition tasks.
