Comp., Component (presented in random order). All conditions were dependent concurrent VI VI schedules with variable-interval timing and 2-s changeover delays. Conditions 1 and 2 were VI 8-s rewards; VI 20-s penalties. Conditions 3 and 4 were VI 20-s rewards; VI 8-s penalties. Reward and penalty schedules ran conjointly and independently of one another (see Critchfield et al., 2003). Conditions 2 and 4 imposed variable-magnitude rewards or penalties (indicated by “v”).
