Learning to align relations: the effects of feedback and self-explanation

Relational similarity connects superficially dissimilar objects and events. In 2 experiments, the ability to recognize and respond to similar relations was studied in children ages 3 to 5 with 2 comparison tasks. Children interpreted illustrated pictures that shared perceptual or relational aspects and then made 2 comparison choices and explanations of these choices. Results of Experiment I demonstrated that when given explicit feedback regarding the relations depicted in the pictures, children learned to respond quickly to this type of similarity in subsequent trials, which involved novel relations. In Experiment 2, the effect of re-explanation on relational understanding was examined. Children age 4.5 to 5 years, but not 3- to 4-year-olds, showed relational learning when asked to explain the experimenter's relational choice.
