Positive behavioral contrast in 3-month-old infants on multiple conjugate reinforcement schedules
Rovee-Collier and Capatides, Journal of the Experimental Analysis of Behavior 32(1), 1979, 15-27. Two experiments with 3-month-old infants whose footkicks activated the objects of an overhead crib mobile, reinforcement proportional to vigour and rate; distinctive colours and patterns signalled the components of a multiple schedule; response reduction appeared in the extinction component and positive behavioural contrast occurred in both experiments.
