1. A method comprising:
- obtaining data representative of a first signal, the first signal gathered from a right side of a brain of an individual while the individual is substantially concurrently exposed to media, the first signal comprising a right alpha wave (α
R) and a right theta wave (θ
R);
obtaining data representative of a second signal, the second signal gathered from a left side of the brain of the individual substantially concurrently as the first signal is gathered, the second signal comprising a left alpha wave (α
L) and a left theta wave (θ
L);
using a processor to calculate a valence value using a formula comprising at least one of;

Abstract
A system and method for calculating a valence value captures an individual'"'"'s positive or negative response to a media by considering alpha asymmetry of the individual'"'"'s brain. This valence value can be used to compare media based on an individual or a group of individuals. Events of the media can be contrasted and compared by the valence value as well. Statistical measurements may be taken to improve media.
