Table \(\PageIndex{1}\): Substages of Piaget’s Sensorimotor Stage2 The child is now able to solve problems using mental strategies, to remember something heard days before and repeat it, to engage in pretend play, and to find objects that have been moved even when out of sight. Take for instance, the child who is upstairs in a room with the door closed, supposedly taking a nap. The doorknob has a safety device on it that makes it impossible for the child to turn the knob. After trying several times in vain to push the door or
turn the doorknob, the child carries out a mental strategy learned from prior experience to get the door opened-he knocks on the door! The child is now better equipped with mental strategies for problem- solving. Abstract Eight- to 12-month-olds might make A-not-B errors, knowing the object is in B but searching at A because of ancillary (attention, inhibitory, or motor memory) deficits, or they might genuinely believe the object is in A (conceptual deficit). This study examined how diligently infants searched for a hidden object they never found. An object was placed in A twice, and then in B. In a different task the object was placed beside A twice, and then in B. Infants made more A-not-B errors in the former task, and perseverating infants searched diligently in A rather than in B. Infants seemed to believe the object was in A, suggesting that both a conceptual deficit and ancillary deficits account for A-not-B errors.

What is AThe A-not-B error occurs when infants search for a hidden toy at the incorrect location when presented with two possible locations (Piaget, 1954). The toy is repeatedly hidden at location A. After a short delay, infants are then allowed to reach for and retrieve the toy.
What affects children's performance on the AFrom a neuropsychological perspective, the cognitive skills of working memory, inhibition, and attention and the maturation of the frontal lobe are requisites for successful A-not-B performance on both the looking and reaching versions of the task.
What is the main finding in rovee Collier's experiment of infant memory?In contrast to the predictions of both Freudian and classic Piagetian theorists, Rovee-Collier found that infants as young as 2 months showed some memory for the mobile.
In which of Piaget's sensorimotor stages are infants delighted by making things happen?Substage 3: Secondary Circular Reactions.
The infant becomes more and more actively engaged in the outside world and takes delight in being able to make things happen.
