Discrete finger response latencies in a simple reaction time task.
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.
