I am planning some active research (for a thesis).  I want to test my
Math 9 students' hemisphericity (hemispheric dominance) and compare
the results with their achievement.  Can someone find me a
hemisphericity instrument that will test for left brain, right brain,
and possibly whole (integrated) brain preferences.  It must have some
sort of positive validity and reliability information as well.  I can
not find any validity or reliability on the Hemispheric Mode Indicator
(HMI); can you?  Also, the Style of Learning and Thinking (SOLAT)
survey gets poor validity reviews from Buros.  Can anyone help me?
