Suckling as incentive to instrumental learning in preweanling rats

Neonatal rats as young as 7 days of age learned, reversed, and retained a left-right discrimination with a nonlactating nipple as the incentive. These results have implications for the ontogeny of associative processes and for their neurological and neurochemical mediators.
