The effects of minor electrical brain stimulation on everyday attention

INTERVENTION: Participants will undergo one session of Transcranial Direct Current Stimulation (tDCS). During this session, 2 mA of tDCS will be applied for 25 minutes over the right medial prefrontal cortex. Each sponge electrode will be 9 cm2. The position of the electrodes will be defined as: Primary Electrode: We will place the primary electrode over the right mPFC as identified by the junction of FP2, FZ, and F4 electrode positions of the 10/20 EEG electrode system. 10 participants will receive positive electrode stimulation, 10 will receive negative electrode stimulation, and 10 will receive no stimulation. Participants who receive no stimulation will still have the primary electrode applied to the scalp, however, stimulation will only last for 10‐seconds: just long enough to generate a slight tingle and blind the subject to his/her condition. Secondary Electrode: We will place the secondary electrode over the left primary motor cortex (M1) as identified by the C3 electrode position of the 10/20 electrode system. CONDITION: Everyday attention PRIMARY OUTCOME: Standardized scores on the Test of Everyday Attention (TEA). SECONDARY OUTCOME: Nil INCLUSION CRITERIA: Healthy Volunteer
