Hermann's Brain Dominance Instrument Psychometric Characteristics and its Use to Reveal Patterns of Brain Dominance in Jordanian University Students

Abstract

This study aims at investigating brain dominance Instrument
Psychometric Characteristics and using it in revealing patterns of
Brain Dominance in Jordanian undergraduate university students,
The two researchers developed Ned Hermann Brain Dominance
Instrument (HBDI). Development went through several steps in which
the instrument validity and reliability was examined. The study
instrument was applied to the sample which consisted of 500 subjects.
The findings of the study revealed the commonness of the brain
dominance pattern associated with the lower left brain part B,
followed by the brain dominance pattern associated with the upper left
brain part A; the brain dominance pattern connected with the left
brain hemisphere was the commonest; and the brain dominance
pattern joined with the right brain hemisphere was less common.
However, the study variables had a significant effect on some brain
dominance patterns at level (a≤0.05). The study ended with some
comments.
