Using a comparative-cultural perspective, this collection of essays examines the co-constructivist nature of human development in culturally organized environments. The contributions also cover a large age span--infancy to adulthood. Chapters in part 1 cover two different directions in the study of early adult-infant interaction from a comparative cultural perspective. Chapters in part 2 are devoted to child socialization in the cultural-ecological contexts of Southern Italy and India. Chapters in part 3 examine the co-construction of self in adolescence. Chapters in part 4 provide a cross-cultural analysis of the meaning of intelligence or "intellectual competence." Following an introduction to the comparative-cultural perspective (Valsiner), the chapter titles are: (1) "The Study of Early Interaction in a Contextual Perspective: Culture, Communication, and Eye Contact" (Scholmerich and others); (2) "Transformation and Construction in Social Interaction: A New Perspective on Analysis of the Mother-Infant Dyad" (Lyra and Rossetti-Ferreira); (3) "'Amoral Familism' and Child Development: Edward Banfield and the Understanding of Child Socialization in Southern Italy" (Benigni and Valsiner); (4) "Childrearing Practices Relevant for the Growth of Dependency and Competence in Children" (Sinha); (5) "Transformation of Women's Social Roles in India" (Verma); (6) "A Co-Constructivist Perspective of Life-Course Changes among Havik Brahmins in a South India Village (Ullrich); (7) "Culture and Self-Concept among Adolescents with Bicultural Parentage: A Social Constructionist Approach" (Minoura); (8) "Persons' Conception of Human Nature: A Cross-Cultural Comparison" (Oerter); (9) "The Meaning of Intellectual Competence: Views from a 'Favela'" (Oliveira); and (10) "Cultural and Environmental Influences in the Acquisition of Concepts of Intellectual Competence" (Keats). An epilogue, "Comparative-Cultural Co-Constructionism and its Discontents (Valsiner) examines some of the difficulties inherent in the comparative-cultural co-constructionist perspective. Each section begins with an editorial introduction, and each chapter includes references. (HTH)
