Meltzoff and Borton (1979) Had 1-Month-Olds Suck on a Nubby

Meltzoff and Borton (1979) had 1-month-olds suck on a nubby or smooth nipple. They later measured the babies' looking times at pictures of smooth and nubby nipples. If visual-haptic relations are coordinated in 1-month-olds, in theory, infants should

A) look longer at the nipple they had sucked.
B) reach out to the nipple they had not sucked.
C) spit out the nubby nipple, but not the smooth nipple.
D) look longer at the nubby nipple if they sucked on the smooth nipple, and vice versa.
