Unconditioned reactivity to footshock in 5-, 7-, 9-, 11-, and 13-day-old rats was assessed by measuring locomotor activity elicited by inescapable shock. Five-day-old rats differed in activity from all ages except the 7-day-olds. The 7-day-olds were less active than the 13-day-olds, and the 9-13-day-olds failed to differ from one another. These findings suggest that an age difference in reactivity to footshock was probably not a determining factor in reported age-related differences in the shock-escape behavior of infant rats.
