Factors Effecting Choice Reaction Time
u While not directly studied, most of the effects
for simple reaction time are expected to
generalize to choice reaction time.
u The Effects of Number of Alternatives
l Hick found reaction time increased as the number
of alternatives increased. (finger press to light):
Hick's Law
l Mowbray found reaction time did not increase as
the number of alternative increased.
l These conflicting results may be resolved in the
next two findings.
