Distinguishes between two types of explanation of epigenesis, predetermined and probabilistic, and proposes that the second type is more scientifically useful. (SS)

Discusses the legitimacy of the use of multiple definitions of epigenesis in developmental psychology, and of the modification of biological models to suit developmental psychology. (Author/SS)

Discusses the use of the concept of epigenesis as a biological model in developmental psychology and examines the role of the environment in an epigenetic theory. (BD)

Examines relationships between the fields of behavior analysis and developmental psychology, surveying the influence of behavior-analytic research within developmental psychology and investigating the integration of the two approaches with respect to metatheory and methodology. (Author/MP)

Maintains that "Individual Development and Evolution: The Genesis of Novel Behavior" (Gilbert Gottlieb) is one of the most creative, integrative, and important works in the field of developmental comparative science. Gottlieb's work has provided scientific basis for the concept that developmental systems, and not genetic reductionism, is the only…

Reviews "Rethinking Innateness: A Connectionist Perspective on Development" by Elman and others (1996). Maintains that the authors argue forcefully that the nature-nurture conflict is a false dichotomy and that they present convincing existence on the possibility of qualitative change. Argues that the authors do not succeed in proposing…

Four basic assumptions of IQ tests - age constancy, scholastic validity, standard environment and performance suggiciency are alien to Piaget's theory. Heredity cannot be statistically separated from environment; therefore, Piagetian theory would suggest the nature-nurture controversy is devoid of meaning. (ST)

Rebuts the Burgess and Molenaar commentary in this issue on the authors' paper concerning sociobiology and human development, maintaining that genes (nature) cannot usefully be construed as independent of the coactional developmental system of which they are a part. (BB)

A discussion of the dynamic interaction of nature and nurture variables in the development of an organism. A dialectical approach is used to integrate the possible interactions between these variables. (BD)

Naturalistic observation of a set of identical twins revealed many differences in personality and motor development. (MS)

Describes the methodological and statistical criteria neccessary for adequate measurement of organism-environment correlations and presents a path anaysis model as an approach to the study of these correlations. (BD)

Reviews J. R. Kantor's reactional biography concept in the context of published literature in the psychology of aging. Kantor's perspective is seen to be compatible with recent views and empirical findings in the psychology of aging. (Author/SS)

Comments on an earlier paper by Lerner and von Eye on sociobiology and human development; general theory in science, especially evolutionary theory; adaptation and behavior plasticity; and modern behavior genetics. Examines assertion that "heritability says nothing about the extent to which a trait is commonly inherited." Discusses…

Discusses the nature-nurture controversy as a manifestation of the underlying assumptions of American education. Suggests these assumptions are neither desirable nor necessary for our society and educational system. (ST)

A dialectical approach is used to explore the relationship between individual specialization, collective adaptation, and rate of environmental change for both higher and lower organisms. The nature-nurture controversy and the "generation gap" are discussed in terms of this interrelationship. (BD)
