1. A method for sensing a valence response for use in rating media comprising:
- stimulating an individual with a media containing an event;
sampling a first signal from a right front brain of the individual while substantially concurrently stimulating the individual with the event of the media;
sampling a second signal from a left front brain of the individual while substantially concurrently stimulating the individual with the event of the media; and
calculating a valence value from one or more frequencies from the first signal and one or more frequencies from the second signal defining alpha asymmetry for comparison with a reference value thereby rating the media based on the difference between the valence value and the reference value for the event of the media.

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.

12. A method for rating media based on the amount that an individual is positively or negatively stimulated comprising:
-
calculating a valence value of the individual for an event of a media; comparing the valence value with a reference value to determine the difference between the amount that the individual was positively or negatively stimulated by the media, and the reference value of the media; and saving the comparison as a measure defining a rating of the event of the media. - View Dependent Claims (13, 14, 15, 16, 17)

27. A system for sensing a valence response for using rating media comprising:
-
one or more sensors operable to sample a first signal from the individual; a processing component connected to the one or more sensors operable to; sample a first signal from a right front brain while substantially concurrently stimulating the individual with the event of the media; sample a second signal from a left front brain while substantially concurrently sampling the first signal with the event of the media; and calculate a valence value from one or more frequencies from the first signal and one or more frequencies from the second signal defining alpha asymmetry for comparison with a reference value thereby rating the media based on the difference between the valence value and the reference value for the event of the media. - View Dependent Claims (28)

29. A system for sensing a valence response for use in rating media comprising:
-
means for sampling a first signal from an individual stimulated by an event of a media; means for sampling a second signal from an individual stimulated by the event of the media; means for decomposing a the first signal and the second signal into a frequency domain; means for separating out one or more frequencies from the signal; and means for calculating a valence value from one or more frequencies from the first signal and one or more frequencies from the second signal defining alpha asymmetry for comparison with a reference value thereby rating the media based on the difference between the valence value and the reference value for the event of the media.
