Three experiments (ns = 20, 10, and 20) were conducted in which the reaction times for responses to complexity were investigated for small-scale, discrete, terminated movements. In a choice reaction-time situation, the reaction time for the finger-lift response was longer than that for the finger-lift response followed by the pressing of another key with the same finger. The reaction times for these responses, however, did not differ in a simple reaction-time situation. The difference in reaction times between these responses may have been associated with some differences in allocation of the subjects' internal resources. The subjects' attention might be more attracted to the more complex response.
