The purposes of this investigation were to examine the effects of the teachers' interventions on the object conflicts between young children in a nursery school and their changes with children's ages. Subjects were eight children and their two teachers. The main data were obtained from the observations of free play in their classroom through bimonthly taken videorecording sessions. Each session lasted 15 minutes. The period of observation was from May 1988 to March 1989. The main changes with age (14-, 18-, 22-months-old) were as follows: (a) The rate of teacher's intervention in the object conflicts between children increased. (b) The rate of "the intervention with mediated functions" (ex., descriptions of the behaviors of the other, and direction for request) increased, but "the rate of physical intervention" (ex., forbidding, and giving another object) decreased. (c) The rate of the children's "rejections" to teacher's intervention increased.
