To determine whether children retain a preference for a previously accurate informant only in the short term or for long-term use, 3- and 4-year-old children were tested in two experiments. In both experiments, children were given accuracy information about two informants and were subsequently tested for their selective trust in the two informants (Experiment 1: immediately, 1 day and 1 week later; Experiment 2: immediately, 4 days and 1 week later). Both age groups preferred to trust the accurate informant not only immediately after receiving accuracy information but also at subsequent time-points. Children who were immediately able to explicitly identify the accurate informant were significantly more likely to seek and accept information from her 1 week later. However, even when they had not been asked to explicitly identify the accurate informant both age groups still maintained their preference for her. Thus, by 3 years of age, children spontaneously choose a previously accurate informant up to 1 week after exposure to information regarding her accuracy.
