Starkey, David – Child Development, 1981
Examines the issue of object sorting in early infancy. Forty-eight infants at 6, 9, and 12 months were presented with eight sets of small, manipulable objects. At six months, selective manipulation was absent; at nine months, 94 percent of the infants sequentially touched similar objects and at 12 months 100 percent did so. (Author/DB)

Hooper, Frank H.; Sipple, Thomas S. – 1975
Matrix tasks to assess multiple classifications and multiple seriation skills were administered to 160 children (40 Ss each from preschool, kindergarten, first and second grade levels). Each child received six matrix subtasks (reproduction and transportation of cross classification I, double seriation, and cross classification II) in one of six…

Friedman, William J.; And Others – Child Development, 1995
Examined developmental changes in the use of distance-based and calendar-based approaches to estimate the recency of two events. Found that children's ability to discriminate temporal relationships between two events appears by four to five years of age. In contrast, use of calendar information and cognizance of annual patterns was found only in…

Lawton, Joseph T.; And Others – 1978
This study compared the effects of a formal, an open-framework, and a control preschool program on children's intellectual development. The formal program, based on Ausubel's and Piaget's theories, had a daily schedule of short prescriptive teaching sessions followed by related learning activities. The informal program, based on Piaget's theory,…

Friedman, William J. – 1979
This study investigated (1) the order of acquisition of related temporal and spatial terms, (2) the application of temporal and spatial terms and (3) the relationship between the application of temporal and spatial terms and performance on cognitive measures of temporal and spatial ordering. Children 3 to 5 years of age were tested on four…

DeLoache, Judy S.; And Others – 1981
A seriation task (assembling a set of nesting cups) was used in this study to examine developmental changes in young children's ability to restructure a situation. Forty young children, eight each at 18, 24, 30, 36, and 40 months of age, participated in the study. Each child was presented with five nesting cups and was told he or she could play…

Lawton, Joseph T.; Ershler, Joan – 1980
Children aged 2-1/2 to 3-1/2 years in three preschool programs were given a test battery consisting of classification, relations, and conservation tasks. One program (Ausubelian) was formal and two programs (Piagetian and Tradition) were informal. Posttest data for the first year of a three-year longitudinal study indicated significantly superior…

Spitz, Herman H.; And Others – Intelligence, 1982
Demonstrated is a covariance principle that causes the observer to assume that if one aspect of a two-dimensional figure (its perimeter or its area) is conserved, the other aspect must also be conserved (pseudo-conservation). Mentally retarded individuals, assuming no such fixed relationship, correctly judged the changed state of the nonconserved…

Park, Ok-Choon; Tennyson, Robert D. – 1979
A total of 132 volunteer 10th and 11th grade students participated in an experiment to investigate two variables of computer-based adaptive instructional strategies for concept learning. The first variable tested the hypothesis that selection of number of examples according to on-task information is more efficient than selection according to…

McCartney, Kathleen A. – 1980
This study focused on the issue of whether "scripts" guide children's comprehension and recall of stories. Two groups of kindergarten and second-grade children (N=48) from middle class elementary school districts were told two stories about typical events in the life of a young child (eating dinner and going to bed). Children were asked to recall…

Pasnak, Robert; And Others – Education and Training in Mental Retardation, 1989
Six mildly and moderately retarded children (ages 6-8) were instructed in the Piagetian constructs of unidimensional classification and/or seriation using the "Piacelleration" learning set technique. After one semester, subjects made significant gains on: classification and seriation tasks, the Peabody Picture Vocabulary Test, and the…

Moore, Gary W. – 1978
A study was designed to develop an instrument and methodological procedure to assess transitive relations within seriation problems in elementary school children using three criteria: explanations, judgments, and strategies. A secondary analysis to assess transitivity used the three criteria according to whether the children were conservers, in…

Liddle, Ian; Wilkinson, J. Eric – British Journal of Educational Psychology, 1987
Describes longitudinal study of the development of understanding of two logical properties of number by 36 children during the first three years of primary school in Glasgow. Piagetian tests and number skills tests were administered to explore the acquisition of number as class and number as order concepts. (Author/LRW)

Lister, Caroline; And Others – Early Child Development and Care, 1996
Through seriation, verbal seriation, and conservation tasks, investigated blind, partially sighted, and sighted children's understanding of quantity. Subjects were 81 children equally dispersed through these 3 groups. Age range was 4 to 17 years. Found similarity in concept acquisition among three groups that extended beyond quantity conservation…

Garrett, Kimberly N.; Busby, Rosetta F.; Pasnak, Robert – 1998
This study examined the effect of an innovative teaching activity to improve concrete operational thinking skills with preschoolers in Head Start programs. A "learning set" of classification games and seriation games was used to teach the oddity principle and insertion into a series. These games were played with the children using toy ponies and…
