The reliability of cognitive demand measures in controlled laboratory settings is well-documented; however, limited research has directly established their stability under real-life and high-stakes conditions, such as operating automated technology on actual highways. Partially automated vehicles have advanced to become an everyday mode of…

In this study, qualitative evidence is collected--through classroom observations and teacher and student interviews--to study the effect of metacognition and the interaction between students' observable cognitive behaviour and the instructional task. This qualitative data is analysed to identify what factors support and improve students'…

Many students now are receiving instruction in online environments created by universities, museums, corporations, and even students. What features of a given online course contribute to its effectiveness? This paper addresses that query by proposing and applying an analytic framework to five online introductory chemistry courses. Introductory…

This study examines the influence of selected performance factors and social role participation upon Piagetian cognitive funcitoning during the aging years. By administering a battery of concrete and formal reasoning tasks and measures of fluid intelligence, the effects of varying instructional set and age of E on the cognitive performance of 80…

When the mathematics and extended range vocabulary subtests on the Relief Format Assessment Test were factor analyzed, altitude estimation (predicted by mathematics aptitude) and terrain analysis (predicted by vocabulary skills) were found to underly map-reading performance. Solutions were found to be dependent on verbal-analytic ability more than…

An exploratory study was undertaken to provide a means of quantifying some of the components of the problem solving process. The focus was on actual problem solving behaviors and strategies as they occurred in relation to different cognitive tasks and subject characteristics. Cognitive tasks included items from Wechsler and Binet intelligence…

One approach to increasing our understanding of the rating process is to examine behavioral components of decision-making. Although observable rater behavior during appraisal is still removed from the actual contents of internal processing, these behavioral indices may provide important clues toward identifying determinants of rating success. To…

To ascertain predictive relationships between and within cognitive tempo and cognitive level characteristics of moderately retarded children, the Matching Familiar Figures Test and Essential Math and Language Skills Inventory were administered. No significant predictive relationship from cognitive tempo to level was indicated, but elements of…

Validated models of mental addition processing by testing children and adults in a production task paradigm. Examined individual-difference relations between strategy choice parameters and criterion-related measures of ability. Found that individual differences in the apparently calculative processes that underlie numerical facility are highly…

Evaluation of the Kaufman Assessment Battery for Children (K-ABC) with 130 primary school children in Zaire revealed three findings: (1) the distinction between sequential processing and simultaneous processing was valid; (2) the K-ABC discriminated effectively among grade levels, health and family environment variables, and tribal membership; and…

The procedures, major findings, and conclusions of the Adolescent Reasoning Project are summarized in this final report to the National Science Foundation. Eleven different experiments were conducted to investigate the role of naturalistic and laboratory task content on scientific reasoning. Participants involved 1500 seventh, ninth, eleventh, and…

A model of conceptual learning and development that provides a framework for studying the course of cognitive development throughout the school years and also studying the learning concepts across short time intervals is discussed in this paper. The theory includes five main propositions. First, children learn four successively higher levels of…

The longitudinal interrelations among age, visual and auditory short-term memory, and the concrete operational tasks of class inclusion and combinatorial reasoning were investigated over four testing occasions in a sample of 134 students, initially ranging from 5 to 12 years in age. The Piagetian task battery involved placement of colored…
