"That one makes things small": Experimentally induced spontaneous memories in 3.5-year-olds.

We introduce a new method for examining spontaneous (unprompted) autobiographical memories in 3.5-year-old children, by inducing them in a laboratory setting. Thirty-eight 3.5-year-olds, who had previously participated in a study in our lab involving highly unique props, were brought back after a one-month delay to the same lab arranged as in the original study and with the same Experimenter present. While waiting for the Experimenter in front of the props, their spontaneous verbalizations about the previous unique experiment were recorded, scored, and compared to those of 29 naïve Controls of the same age. The children in the experimental group produced significantly more spontaneous verbalizations related to the to-be-remembered event measured on a variety of dimensions. The study introduces a promising new approach to investigating spontaneous memories in young children in a controlled lab setting. The findings are discussed in relation to involuntary autobiographical memories as examined in adults.
