Both groups of stimulation were in turn subdivided in two groups, anodal and cathodal.
We also found a significant reduction in RTs for utilitarian responses after cathodal VPC-tDCS, regardless of type of dilemmas and of sex.
Our results nevertheless showed that cathodal tDCS decreased RTs for utilitarian responses but left the proportion of utilitarian responses unchanged.
To assess the effect of tDCS on mood, we computed the differences (after-before tDCS) and tested them in a three-way within subjects analysis of covariance (ANCOVA) with tDCS (anodal, cathodal VPC-tDCS and anodal, cathodal OC-tDCS) and gender (males, females) as factors and education and religion as covariates for mood VAS and happiness VAS.
In females, cathodal VPC-tDCS tended to decrease whereas anodal VPC-tDCS significantly increased utilitarian responses (p = .005).
Also, cathodal VPC-tDCS reduced RTs for utilitarian responses in both males and females.
A central point to clarify is how anodal and cathodal tDCS differentially modify utilitarian choices.
We therefore conclude that anodal and cathodal tDCS both interfere with rational decisions, or rational evaluation of the advantages and disadvantages of each option in both sexes, but do so more strongly in females.
However, whereas cathodal tDCS alters the time of utilitarian reasoning in both sexes, anodal stimulation interferes more incisively, modifying utilitarian reasoning and its possible consequent actions, also in a gender-specific way.
For each item, the response of a given subject, a given stimulation (anodal, cathodal VPC-tDCS and anodal, cathodal OC-tDCS) and a given time (pre, post tDCS) was coded as 0 (non-utilitarian) or 1 (utilitarian) and the corresponding RT was entered.
