This paper discusses the distinct meanings of "internalization" and "interiorization" as ways of rendering intelligible the social constitution of the psychological in a line of research that started with Piaget and extended into a post-Piagetian reformulation of intelligence in successive generations of studies of the relations between social…

Instead of limiting himself to postulating two discontinuous types of thought, autistic and logical, Piaget studied transitional forms, thereby placing autistic and logical thought on a developmental continuum. Nevertheless, the discovery of transitional forms did not lessen the opposition between the two extremes of autistic and logical thought.…

Growing out of a child's cognitive developmental history, formal operation becomes established at about the age of 12-15 years. The essence of the logic of cultured adults and the basis for elementary scientific thought are thereby provided. The rate at which a child progresses through the developmental succession may vary, especially from one…

Suggests an upward extension of Piaget's theory through dialectic operations because the current theory fails to represent adequately the thought and emotions of mature and creative persons. (CS)

Tests designed to measure conservation, visual memory, and static and anticipatory imagery were administered to 1st and 2nd grade children. Conservation and memory correlated significantly with IQ. The different mental processes may be involved in the development of anticipatory imagery and conservation. (CS)

The term experience'' has been used by developmental psychologists to refer both to effects of environmental stimulation and to opportunity for the acquisition of a particular behavior. Differing conceptions of the role of experience and their consequences for various issues in the field are discussed. (ST)

Describes an early formative period in Piaget's life, in which three themes stand out. First, Piaget was introduced to the concept of "autistic" or nonrational thought. Second, Piaget's philosophical education sensitized him to the role of logic in thought. Third, Piaget's exposure to biological taxonomy alerted him to look for…

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)

Suggests that although Piaget's psychological theory is developmental and dialectical in a general way, the lack of a developed philosophical basis leads to the subordination of a dialectical approach to static, anti-dialectical concepts. Hegel's theory of interaction and contradiction is examined to show that dialectical theory has a precise…

Development of memory depends upon changes in several mnemonic processes, which are illustrated in experiments with normal and mentally retarded adults and children. (Author/WY)

In an investigation of the relationship of the logical operations to other developmental sequences, 30 college students were assessed as to logical operational ability and poetic interpretation. The strong relation found between these two abilities supports the theoretically predicted applicability of central, formal reasoning structures to…

Comments on the blending by Dean, in her article in this issue, of Loewald's instinctual-affective component with the developmental models of Piaget and Vygotsky, with internalization as the pivotal concept. Suggests that Dean's synthesis mirrors development itself, as it first differentiates and then integrates the work of the three theorists.…

Suggests intelligence tests are culture bound and as such miss many abilities particularly those of minority groups. (ST)
