The influence of set on a simple reaction time task was examined by comparing the differences of psychological factors between a group of subjects who expected and experienced a fixed foreperiod (Control condition: 12 subjects) and another group of subjects who were instructed to expect variable foreperiods but experienced the same fixed foreperiod (Instruction condition: 11 subjects), using the index of contingent negative variation (CNV). The foreperiod of simple reaction time cask in each condition was fixed at 3 sec. Subjects were required to respond to 2 blocks of 24 trials, and each instruction was presented between blocks. On the second block CNV amplitudes were higher in the instruction condition as was every CNV component (early, late, and whole components). The set created by anticipating variable foreperiods seems to increase cerebral activity, arousal, and attention during simple reaction time tasks.

The present study evaluated the potential for neuroanatomical factors to operate in a simple reaction time task. That is, response latencies were recorded for all ten fingers on a Donders' A reaction time task. Two finger-placement conditions were used, a single response key condition and a multiple response key condition. This latter condition required subjects to place all ten fingers on response keys. 30 male, right-handed subjects participated. No significant effects were found, indicating that there are no intrinsically slow or fast fingers. This finding is discussed in the context of reaction time differences between individual stimulus-response (finger) pairs in choice-reaction time tasks.
