Planning by 12-Month-Old Infants.
Willatts, Peter; Rosie, Karen
In an investigation of 1-year-olds' ability to plan a sequence of steps, 20 infants were administered a compound means-ends problem. In a planning condition, a barrier was placed in front of a cloth at the far end of which was placed one end of a long string. A toy was fastened to the other end of the string and was placed on a table at some distance from the cloth. To retrieve the toy, the infant had to remove the barrier, pull the cloth, and grasp and pull the string. In a control condition, the same arrangement of barrier, support, and string was used, but the toy was visibly separate from the string. Each infant was given five trials on both conditions with order counterbalanced. Findings revealed that when the toy was fastened to the string, infants were more likely to remove the barrier without playing with it, were quicker to reach for the support, and retrieved the string more frequently. When the toy was separate from the string, infants played more with the barrier, were much slower to contact the support, and often failed to retrieve the string. Order of task had no effect on performance. Results indicate that 12-month-olds are able to plan a series of steps to achieve a goal, and are not restricted to the use of trial-and-error methods in which problems can only be solved by proceeding one step at a time.
