Effect of tDCS Montage on Measures of Appetite

Completed · Not applicable · Has a placebo group

Conditions studied: Eating Behavior

In brief

The aim is to validate a new sham (control) method for use in transcranial direct current stimulation (tDCS) that is less discernible to participants from the real condition. Participants are often able to tell real from sham conditions. Correctly guessing real from sham undermines the integrity of evaluations of the value of tDCS as a treatment tool as responses may be in part or entirely the result of treatment expectation effects. The study will test a new sham method to reduce food craving and eating and test how much participants are able to discern it from the real or 'target' condition.
