Do preschoolers save to benefit their future selves?

Using a new paradigm for measuring children's saving behaviors involving two marble games differing in desirability, we assessed whether 3-, 4-, and 5-year-olds saved marbles for future use, saved increasingly on a second trial, saved increasingly with age, and were sensitive to the relative value of future rewards. We also assessed whether performance on the saving paradigm was related to theory of mind performance. Children saved significantly more marbles on the second trial than the first and saved significantly more when a future reward was more desirable than a present reward (rather than the reverse). However, older children did not save significantly more than younger children. Performance on one of two false belief tasks was not correlated with saving behavior and performance on the other was only marginally correlated with the number of marbles saved on trial 2. Implications for children's future thinking and comparative research are discussed.
