This paper describes a series of longitudinal experiments which dealt with the development of object awareness in infants, ages 6-18 months. The experiments were designed to document and evaluate Piaget's account of this development. The studies focused on two types of phenomena: (1) when infants first find an object hidden in one place, they will…

The purpose of the present study was to determine if a developmental sequence could be established for the appearance of conservation. A series of four dimensional tasks and a conservation task were administered to 25 kindergarten girls and 25 kindergarten boys. The dimensional tasks tested understanding of comparative and superlative terms along…

Five conference reports that originally appeared as monographs of the Society for Research in Child Development concern cognition in young children. Included in a section on thought are articles on Piaget and his theories, computer simulation on human thinking, and an information processing theory of intellectual development. The development of…

Because knowledge of the component subskills of causal reasoning would aid in planning elementary science curricula, this study sought to identify component abilities through the individual administration of a battery of 29 tests to a randomly-selected sample of 84 first-graders, evenly divided by sex. These tests were: (1) verbal tests of…

The Ontario Institute for Studies in Education and the Canadian Mothercraft Society are running a day care program for infants (from 3 to 30 months of age) designed to facilitate their cognitive, personality, and social development through personalized adult-child interaction, guided learning situations, free play, and specialized care.…

This paper represents a preliminary attempt to determine universals of grammatical development in children. On the basis of language acquisition data, a limited number of findings are presented in the form of suggested developmental universals. These universals are grouped according to the psychological variables which may determine them, in the…

The purpose of this study was to determine if an effective conservation training procedure would be one in which a child was confronted with opposing points of view. Subjects were 108 children with a mean age of 6.7 years. In two experiments, a group of three children (generally one nonconserver and two conservers) was required to respond with one…

The first issue of the IRCD Bulletin describes the scope and functions of the Information Retrieval Center on the Disadvantaged. Noted is its focus on the psychoeducational development of socially disadvantaged children and youth. To aid professionals working in this field, IRCD serves as an information clearinghouse and publishes bibliographies…

Fifty-four 5-year-old Head Start children participated in a study of the effect of varied versus repeated training on the development of the ability to categorize and transfer learning. The children were grouped according to chronological age and results of a mastery test and the Peabody Picture Vocabulary Test. Work categories translated into…

Twelve culturally disadvantaged 4-year-olds of borderline normal intelligence were subjects of this study. Its primary purpose was to test further the cognitive learning theory previously developed, as well as the reinforcement system, the facilities, and the experimental-longitudinal methods of research. The study did not include a control group…

Factor analysis was used to test the hypothesis that College Level Examination Program (CLEP) General Examinations, when administered to students who have completed 2 years of college, do not measure anything different from that measured by the traditional battery of pre-college aptitude examinations. The CLEP examinations were taken in the fall…

The Experienced Teacher Fellowship Program at Hofstra University involves the participants in investigating the structure, claims, and methodologies of the natural sciences, mathematics, social sciences, and the psychological findings of Piagetian-oriented cognitive development studies. The Fellows in the program form groups to decide on research…

Three units of instruction were given to 20 four-year-old children and 34 five-year-old children. Unit I was designed to develop the children's ability to establish a length relation between curved lines; Unit II, to develop ability to conserve length; and Unit III, to develop ability to conserve length relations. Testing of the children occurred…

Theories and practices concerned with cognitive functioning and development and its possible relationship to reading and reading instruction are reviewed. The nature of the strategies involved in reading and thinking are similar. Increase in task complexity for reading most likely involves cognitive functioning that ranges in complexity similar to…

Relationships between school achievement and two theoretically different measures of intelligence, Piagetian and psychometric, are explored in 143 bright, average, and retarded elementary school students. Factor analyses of the California Test of Mental Maturity, the Metropolitan Achievement Test, the Stanford-Binet, and fifteen Piaget-type tasks…
