A-not-B error (also known as "stage 4 error" or "perseverative error") is a phenomenon uncovered by the work of Jean Piaget in his theory of cognitive development of children. The A-not-B error is a particular error made by infants during substage 4 of their sensorimotor stage. A typical A-not-B task goes like this: An experimenter hides an attractive toy under box "A" within the baby's reach. The baby searc…

A-not-B error (also known as "stage 4 error" or "perseverative error") is a phenomenon uncovered by the work of Jean Piaget in his theory of cognitive development of children. The A-not-B error is a particular error made by infants during substage 4 of their sensorimotor stage. A typical A-not-B task goes like this: An experimenter hides an attractive toy under box "A" within the baby's reach. The baby searches for the toy looks under box "A" and finds the toy. This activity is usually repeated several times (always with the researcher hiding the toy under box "A"). Then in the critical trial the experimenter moves the toy under box "B" also within easy reach of the baby. Babies of 10 months or younger typically make the perseveration error meaning they look under box "A" even though they saw the researcher move the toy under box "B" and box "B" is just as easy to reach. This demonstrates a lack of or incomplete schema of object permanence. Children of 12 months or older typically do not make this error.

Traditionally this phenomenon has been explained as the child seeing an image and remembering where it was rather than where it is. Other accounts deal with the development of planning reaching and deciding things. There are also behaviorist accounts that explain the behavior in terms of reinforcement. This account argues that the repeated trials with hiding the toy in box "A" is reinforcing that spe…

Traditionally this phenomenon has been explained as the child seeing an image and remembering where it was rather than where it is. Other accounts deal with the development of planning reaching and deciding things. There are also behaviorist accounts that explain the behavior in terms of reinforcement. This account argues that the repeated trials with hiding the toy in box "A" is reinforcing that specific behavior so that the child still reaches for box "A" because the action has been reinforced before. However this account does not explain the shift in behavior that occurs around 12 months. Smith and Thelen used a dynamic systems approach to the A-not-B task. They found that various components of the activity (strength of memory trace salience of targets w...
