Toddlers' action learning and memory from active and observed instructions.

From early in life, children learn to perform actions on the objects in their environments. Although children learn from observing others' actions, actively engaging with the material to be learned can be important for learning. This study tested whether instruction that included opportunities for children to be active supported toddlers' action learning. In a within-participants design, 46 22- to 26-month-old toddlers (average age = 23.3 months; 21 male) were introduced to target actions for which instruction was either active or observed (instruction order counterbalanced across children). During active instruction, toddlers were coached to perform a set of target actions. During observed instruction, toddlers saw a teacher perform the actions. Toddlers were then tested on their action learning and generalization. Surprisingly, action learning and generalization did not differ between instruction conditions. However, toddlers' cognitive maturity supported their learning from both types of instruction. One year later, children from the original sample were tested on their long-term memory for information learned from active and observed instructions. Of this sample, 26 children provided usable data for the follow-up memory task (average age = 36.7 months, range = 33-41; 12 male). Children demonstrated better memory for information learned from active instruction than for information learned from observed instruction (odds ratio = 5.23) 1 year after instruction. Active experience during instruction appears to be pivotal for supporting children's long-term memory.
