Abstract
An experimental test was made of Hull’s (1943) notions that reactive inhibition (IR) is effector-specific and that it has primary negative motivational properties. Four groups of 20 subjects (10 males and 10 females in each) executed two segments of continuous right-hand practice on a mirror-tracking task. The two segments were separated either by 0 min rest, 5 min rest, 5 min continuous right-hand practice on rotary pursuit, or 5 min continuous left-hand practice on rotary pursuit. Effects of interpolated conditions were measured in terms of main-task reminiscence and initial post-treatment performance. When interpolated practice was conducted with the right hand, reminiscence and post-treatment performance were significantly depressed relative to the rest effect, but not when interpolated practice was conducted with the left hand. Thus, Hull’s views were supported, while competing views, such as the task specificity concept of IR and the consolidation theory of reminiscence, were impugned.
