- Primary Outcome Measures
Name Time Method Pre versus post performance on attentional bias assessment task.<br><br>Attentional bias assessment task: the attentional bias assessment task is a computerised dot-probe task. It follows the same format as the attentional bias modification in that it involves simultaneous presentation of positive and negative stimuli. It differs in that the dot probes are are presented in a 50:50 positive: negative contingency and differences in reaction time to positive and negative stimuli are used to infer attentional bias. [Immediately post attentional bias modification training with active/sham tDCS.]
- Secondary Outcome Measures
Name Time Method Pre versus post intervention EEG activity during completion of an emotive sternberg working memory task.<br><br>Emotive Sternberg Task: comprises blocks of positive, neutral and negative stimuli. Differences in accuracy and reaction times by valence and stimulation condition will be examined. [Immediately post attentional bias modification training with active/sham tDCS.]
