Research on Trait by Treatment Interaction must become more coordinated. It should include systematic programs by individual investigators as well as those among investigators. Important factors to consider are (1) developing a clearer definition of traits which will include availability and preference as well as aptitude and ability in both the…

Reported are the results of a study of the Piagetian formal thought range of 3600 students, 13 to 15 years old, in seven countries: Denmark, Sweden, Italy, United States, Austria, Germany, and Great Britain. Cognitive measurement was obtained by group administration of two tasks to assess proportional reasoning and control of variables. Overall…

For the sake of simplicity and brevity, the development of psychometrics is discussed mainly in the context of studies of individual differences. (Author/AM)

Determination of the nonintellectual characteristics of migrant children that are involved in development of the child's readiness for academic material was the purpose of this study. (Author)

This study focused on the psychological process involved in drawing inferences from pictures. Nineteen reference tests and two tests of picture interpretation behavior were administered to a random sample of 95 children aged 10-12: the Production of Inference Tests (PIT) and the Discovery of Similarities Test (DST). (JEG)

Describes a study of 708 eleventh and twelfth graders of cognitive development and their ability to learn physics. The theories of Piaget were used as a model to study the teaching and learning of physics. (MDR)

Investigates the prevalence of developmental cognitive differences among college students and the relation of scores on cognitive tests to an objective form of assessment of achievement, namely, the final grade in a conventional physics course. (GA)

Employs cognitive mapping and behavioral mapping strategies in conjunction, using behavioral data to help verify the cognitive mapping findings. Indicates that both observed and reported environmental behavior patterns are directly related to those spatial areas emphasized or excluded in the cognitive maps and to subjective distortions in mapping.…

A reply to a critique of Pascual-Leone's model of children's information processing capacity. (BD)

Cognitive preference as used in this research refers to a conscious decision which the subjects were forced to make, thus suggesting a relative rather than an absolute preference as with cognitive style. It was predicted that the scores derived from the cognitive preference scale would serve as good indicators for the mode of instruction from…

Three data sources, analyzed presently, failed to reveal a Sex by Race or Sex by Socioeconomic Status interaction. It was suggested that Sex by Race differences in income, education, and so on could be the result of racially related sex role expectations or cultural prejudice. (Author/MV)

Two studies investigated the functional equivalence of three different scoring systems used to assess the child's ability to understand and carry out multiplicative classification tasks. All three scoring criteria produced reliable and homogeneous tests. Their factor matrices were similar, and the corresponding factor structures were invariant…

The rule space model permits measurement of cognitive skill acquisition and error diagnosis. Further discussion introduces Bayesian hypothesis testing and bug distribution. An illustration involves an artificial intelligence approach to testing fractions and arithmetic. (Author/GDC)

Discusses the impact of computer programing instruction on cognitive skills and suggests two mechanisms of transfer--low road, from practice, and high road, from generalization. Previous research that tried to measure transfer from programing is reviewed, six categories in which transfer might occur are presented, and 71 references are provided.…

Examined stability of the Kaufman Assessment Battery for 53 at-risk preschool children. Over 9 months the stability coefficients for the global scales ranged from .78 to .88, and for the subtests from .65 to .79. Concluded that scores display adequate stability, but the Simultaneous scale is less stable than the Sequential or Achievement scales.…
