title: Anticipated reward and time estimation in young Navajo children.
abstract: Time estimations of 1-min. intervals using the method of reproduction by 112 Navajo children were measured under neutral and reward conditions in a repeated-measures design. Anticipated reward (a piece of candy) significantly reduced the accuracy of time estimations. In contrast to previous research the girls were more accurate than the boys; however, the effect of reward was more pronounced for girls than for boys. These data suggest that motivating factors play an important role in the reproduction of time by Navajo children.
