title: An observational study of the affective concomitants of mastery in infants.
abstract: The hypothesis that attempts at motor mastery were accompanied by positive affective responses was tested in an observational study of 9-11-month old infants in a daycare setting. Five infants were observed as they attempted three age-appropriate motor tasks--pulling to stand, standing with support, and taking steps with support. Positive affective responses included smiling, babbling, and laughing. The five infants were observed for a total of 82 hours. The proportion of positive affective behaviors associated with practicing new motor tasks was compared to the proportion associated with well-practiced tasks. The hypothesis that more positive affective behaviors would be associated with attempts at mastering the new motor tasks was confirmed. There was no diminution in the association between the new motor tasks and positive affect as the infants continued to practice and master the three motor tasks. The results are discussed in terms of individual differences in mastery motivation and the often suggested continuity between early mastery motivation and later competencies.
