Apprendre a mesurer la durée: études chez des enfants âgés de 4 à 7 ans.

Conducted 3 studies of young children's use of duration indicators (hour glass or metronome) and use of counting to estimate brief durations. Human Ss: Six normal male and female French preschool children (mean age 4.5 yrs) (Exp 1). 18 normal male and female French preschool children (mean age 4.5 yrs) (Exp 2). 18 normal male and female French school-age children (mean age 6 yrs) (Exp 2). 12 normal male and female French school-age children (mean age 6 yrs 10 mo) (elementary school students) (Exp 3). In Exp 1, Ss were trained to produce a response for a set duration in the presence of a luminous array composed of small diodes that changed from green to red to indicate the target duration. In Exp 2, Ss were trained to space their responses using a critical duration with an audiovisual metronome that beeped at different intervals. In Exp 3, Ss were asked to reproduce the durations of the illumination of a bulb or the intervals between 2 light flashes.
