[Development of delay of gratification in preschool children].
Developmental changes in delay-choice behavior and delay-maintenance behavior were investigated in situations, in which the difference in value between immediate reward and delayed reward was set small (S situation) and large (L situation). Ninety kindergarteners aged four, five and six were assigned to either one of the two situations. (1) In S situation, the choice of immediate reward was dominant in all age groups. (2) In L situation, the choice of delayed reward was dominant in all age groups. (3) In S situation, 6-year olds maintained longer delay than 4- and 5-year olds. (4) The delay time of 4- and 5-year olds in L situation was longer than that in S situation and was not significantly different from that of 6-year olds in L situation.
