Relatedness support enhances motivation, positive affect, and motor learning in adolescents.

Social relatedness is a basic psychological need to experience satisfaction of interpersonal acceptance and closeness with others. In this experiment, the effects of social relatedness on the learning of a task (hitting a ball with a racket toward a target) were tested in adolescents. Participants were assigned to three experimental groups. After a pre-test and before practice, participants in the relatedness support (RS) condition received instructions emphasizing recognition, importance, and interest in the participant's experience. Participants in the relatedness frustration (RF) condition received instructions emphasizing disinterest in the participant as a person. Control participants did not receive specific relatedness instructions. One day later, they performed retention and transfer tests. Questionnaires measured participants' motivational and affective levels. The results showed that supporting the relatedness need enhances task learning in adolescents. Motivation and affective levels were also affected. The findings are the first to show that social relatedness affects adolescent's motor performance and learning and reveal underlying mechanisms implicated in such effects.
