160 1ST-4TH GRADE GIRLS WERE GIVEN 1 OF 10 TRAINING PROGRAMS DESIGNED TO PRODUCE VARIATIONS IN ALTRUISTIC BEHAVIORS IN 2 DISTINCT DONATION SITUATIONS. CHILDREN SACRIFICED THE OBTAINING OF M + M CANDIES WHEN THEY HAD A WARM RELATIONSHIP WITH E WHO MADE EXPLICIT HER PLEASURE AT SUCH SACRIFICE. NEITHER A WARM RELATIONSHIP NOR EXPLICIT STATEMENTS OF JOY BY E ALONE WERE MORE EFFECTIVE THAN NO TRAINING IN ELICITING SUCH CHARITABLE BEHAVIOR. SS' SUBSEQUENT ANONYMOUS DONATIONS WERE HIGHLY CORRELATED WITH PREVIOUS TRAINING PROGRAMS. IT WAS CONCLUDED THAT POSITIVE INTERPERSONAL RELATIONSHIPS AND EXPLICIT STATEMENTS OF PLEASURE BY THE SOCIALIZING AGENT CAN PROVIDE THE BASIS FOR THE INTERNALIZATION OF THE NORM OF SELF-SACRIFICE.
