Left and right in the Bible from a neuropsychological perspective.

Although in several neuropsychological works dealing with hemispheric specializations a few passages of the Bible referring to the left and the right have been mentioned now and then, a systematical study with a neuropsychological approach to this topic was still a missing link. By using concordance texts from the Bible books of the Hebrew Canon (Old Testament, OT) and from the New Testament (NT), all the verses containing any reference to the left and the right (OT = 151, NT = 49 verses) have been identified and classified into 10 groups: (1) references to space, (2) symmetric sayings, (3) the right hand is the favorite hand, (4) right eye preference, (5) God's right hand, (6) the right side is more prestigious, (7) the right side in liturgy, (8) left hand preference, (9) fatal left-hand shots, and (10) on the left side. Some statistical considerations have been put forward and a neuropsychological, anthropological approach has been suggested for the purpose of interpreting the most interesting verses. According to the author of the present paper, it would be worthwhile commenting on some texts of ancient and modern literature not only from a linguistic, historical, religious and theological point of view, but also by means of a neuropsychological approach.
