Hur påverkas uppmärksamhet och arbetsminne av stimulering med tDCS och auditivt brus?

Sammanfattning: To sustain attention rather than getting caught by distractions is of utter importance for our working memory. The present study compared two techniques, transcranial direct current stimulation (tDCS) and white noise, as an attempt to enhance the attention of the test subjects. Attention was tested with a go/no-go test and working memory with an n-back test. The findings showed that the test subjects received a significantly improved working memory score when stimulated with tDCS and noise. Having the 2SR model as a theoretical framework, predicts an interaction between attention and the effects of tDCS and noise. The results in this study confirms this prediction by significant correlations regarding improved attention, seen on reaction time differences in go/no-go, and level of attentiveness measured by Snapscore-IV. The conducted study could not, however, conclude significant differences on the attention test score with either of the techniques.
