Analyzes relationships between directly observed infant and mother behavior and infant temperament characteristics, as described in maternal ratings; separates the effects of different variance components in prediction of the observed behaviors; and explores possible interactions between infant sex and infant temperament in determining both infant…

INVESTIGATIONS INTO THE NATURE AND DEVELOPMENT OF SOCIAL AND EMOTIONAL BEHAVIOR IN HUMAN INFANCY HAVE RAISED MANY RESEARCH ISSUES AND HAVE INDICATED MANY ADDITIONAL AREAS OF INQUIRY. EARLY AND CONTEMPORARY STUDIES HAVE BOTH BEEN CONCERNED WITH PROVIDING MORE PRECISE ANALYSES OF STIMULUS AND SITUATIONAL DETERMINANTS OF SOCIAL AND EMOTIONAL…
