The monohemispheric auditory median reaction times

The 11 healthy subjects show the following interhemispheric differences in auditory tasks  

The following subjects are in the task a221 faster than in the task a22r P07, PIO, P14, The following subjects are in the task a22r faster than in the task a221 P03, P21, P06, P20, 

The following subjects have nearly the same reaction time in a221 and a22r P15, POl, P19, P12, P15 

That means in auditory tasks there is no clear preference of one side.
