The basic problem of Jack is that he is not able to do two activities together i.e seeing and hearing at the same time due to which he is unable or feels difficulty in reacting.

This means that Jack lacks co-ordination between these two activities and hence he must work on the co-ordination of seeing and hearing activity together.
