In unidimensional absolute identification tasks, participants identify stimuli that vary along a single dimension. Performance is surprisingly poor compared with discrimination of the same stimuli. Existing models assume that identification is achieved using long-term representations of absolute magnitudes. The authors propose an alternative…

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…

In order to verify claims made by Genevan researchers that linguistic production but not comprehension capabilities distinguish seriators from nonseriators, three tasks were administered to children between the ages of four and eight. Subjects were asked to arrange in order objects varying in size, to describe how the objects differed from each…

This study examines problems related to (1) the development of children's understanding of temporal cycles, and (2) the relationship between cyclic concepts and cognitive development. Piagetian tests of classification and seriation and a variety of specially designed cyclic tasks were administered to 62 children, ranging in age from 4 to 10 years.…

The sentence-picture comparison task requires Ss to decide, as quickly as possible, whether a sentence correctly describes a feature of a picture. (Author)

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…

To investigate reasoning capacities involved in learning to read, a Test of Multiple Seriation (from Piaget) was developed. Problems of a test used by Lunzer and Dolan are discussed. Results showed that word recognition and reading comprehension at age nine correlate significantly with multiple seriation, independent of IQ. (Editor/SJL)

Studied effectiveness of instruction in seriation and classification for kindergartners cognitively lagging behind their peers. Found that extensive classification and seriation instruction in a variety of formats was particularly helpful in facilitating cognitive gains for struggling kindergartners. Individualized instruction provided children…

Quantifies and confirms subjective impressions of similarity and differences in musical monophonic scores. Adapts concepts from sequence comparison theory and uses algorithms to define distances between any two melodies created by tone and rhythmic structure. Presents and applies a generalized algorithm for identifying locally similar portions in…

Discusses opportunities to use nursery rhymes to aid in the mathematical development of young children. Considers rhymes that involve patterns, ordering, and problem solving. (MKR)

Single-task and dual-task versions of verbal and spatial serial order memory tasks were administered to 120 students tested for working memory capacity with four previously validated measures. In the dual-task versions, similarity between the memory material and the material of the secondary processing task was varied. With verbal material, three…

Preference orderings among a set of options may depend on the elicitation method (e.g., choice or pricing); these preference reversals challenge traditional decision theories. Previous attempts to explain these reversals have relied on allowing utility of the options to change across elicitation methods by changing the decision weights, the…

Two processes, serial and hierarchical, are generally opposed to account for grammatical encoding in language production. In a developmental perspective, the question addressed here is whether the subject-verb agreement during writing is computed serially, once the words are linearly ordered in the sentence, or hierarchically, as soon as the…

Although television is highly dependent on language and semiotic analysis, its form can best be analyzed through the structural notion of transformation. The critic's task becomes the articulation of structural laws intrinsic to television. One such law has to do with how television structures time. Television programming transforms action into…

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…
