Abstract
We have recently proposed a new information criterion LIR (Laterality Index at Rest) defined in terms of oxy Hemoglobin concentration changes from the right and left PFC. This information criterion consists of the difference of the right and left oxy Hemoglobin concentration changes summed over the analysis period normalized in such a way that the resulting value falls within the interval [-1,+1]. In a previous study, we demonstrated that there is a positive Correlation between LIR and STAI-1 (State Anxiety of State-Trait Anxiety Inventory). There were at least two issues to be improved:(i) The number of data was small.(ii) Parametric form of the distribution of Pearson Correlation Coefficient was difficult to obtain.In this study, we used the bootstrap algorithm to improve the above issues. We have also examined if there is any distinction between young and old subjects as well as between male and female subjects.
