Correlates of mastery-related behavior: a short-term longitudinal study of infants in their second year.

The present study examined correlates of mastery-related behavior across the infants second year of life. Maternal control style was quantified on a control to support-of-autonomy continuum, infant-mother attachment was assessed in the Strange Situation, and mastery-related behavior was observed in a toy play session at 12 and 20 months. Infants whose mothers were supportive of their autonomy displayed greater task-oriented persistence and competence during play than did infants of more controlling mothers; securely attached and avoidant infants tended to exhibit greater persistence at tasks than anxious-ambivalent babies, and ambivalent babies were the most negative in affect.

Maternal control style and the mastery motivation of one‐year‐olds

Forty-one mothers and their 12-month-old infants participated in a study of the effects of maternal control style on infant mastery motivation. Three scales were designed to assess maternal control style during a mother-infant play session. Mastery motivation was assessed in an experimenter-administered structured toy play procedure. Three components, persistence, competence, and affect, comprised the measure of mastery motivation. Mothers also completed questionnaires on child-rearing attitudes, infant temperament, and control style. Results showed that maternal attitudes and behavior were correlated with infant mastery motivation. More specifically: autonomy-oriented control behavior, sensitive care and knowledge of child-rearing were positively related to infant mastery motivation. The results provide converging evidence regarding the multiple aspects of maternal behavior which affect infant motivation.
