摘要：Disclosed is an system for measuring mood states, which calculate and views high-accurate mood indices from brain activation signals obtained by a non-invasive biospectrometric technology, taking account into differences among individuals, for example cognitive capacity using methods supporting the measurement of mood states of individuals. The system of the present invention stores a plurality of different mood index calculation formulae, selects one of the plurality of mood index calculation formulae based on a personal trait, for example the working memory task performance or working memory capacity of a subject, and substitutes the brain activation data of the subject for the selected calculation formula to calculate and view mood indices.

主权项：1. A system for measuring mood states comprising: a measuring apparatus configured to repeatedly measure a signal of a first brain activation value during a reaction in a brain of a subject to a first type of cognitive task requiring spatial working memory and a signal of a second brain activation value during a reaction in the brain of the subject to a second type of cognitive task requiring verbal working memory; an input unit for entering measured data of the first and second brain activation values and personal trait information on working memory capacity of the subject; a memory unit for storing a plurality of calculation formulae for calculating mood indices on the basis of a difference between the first brain activation value and the second brain activation value; a calculation unit for calculating mood indices; and an output unit for outputting the calculated mood indices, wherein the calculation unit selects one of the plurality of calculation formulae for calculating mood indices based on the personal trait information; substitutes the first and second brain activation values into the selected calculation formula to calculate mood indices; and outputs the calculated mood indices from the output unit.
