Behavioral research demonstrates a critical transition in preschooler's mental-state understanding (i.e., theory of mind; ToM), revealed most starkly in performance on tasks about a character's false belief (e.g., about an object's location). Questions remain regarding the neural and cognitive processes differentiating children who pass versus…

Process-Overlap Theory (POT) suggests that measures of cognitive abilities sample from sets of independent cognitive processes. These cognitive processes can be separated into domain-general executive processes, sampled by the majority of cognitive ability measures, and domain-specific processes, sampled only by measures within a certain domain.…

The current study used the directed forgetting paradigm in implicit and explicit memory to investigate the concreteness effect. Event-related potentials (ERPs) were recorded to explore the neural basis of this phenomenon. The behavioral results showed a clear concreteness effect in both implicit and explicit memory tests; participants responded…

Some situations require one to quickly stop an initiated response. Recent evidence suggests that rapid stopping engages a mechanism that has diffuse effects on the motor system. For example, stopping the hand dampens the excitability of the task-irrelevant leg. However, it is unclear whether this "global suppression" could apply across wider motor…

Researchers and educators recognize that performance assessments and naturalistic observations are well suited for assessing young children's thinking abilities and understanding. The need to establish explicit evaluation criteria to guide assessment decisions has led to the widespread use of rubrics. Rubrics tend to channel assessors to look for…

Task analyses have traditionally been framed in terms of overt behaviors performed in accomplishing tasks and goals. Pioneering work at the Learning Research and Development Center looked at what contribution a cognitive analysis might make to current task analysis procedures, since traditional task analysis methods neither elicit nor capture…

Recent research studies and texts in composition demonstrate the growing belief that students' difficulties with the writing tasks assigned to them are inextricably linked with their difficulties in handling complex cognitive processes. Through appropriate writing activities, students can be provided with practice in the intellectual functions…

After consideration of the drawbacks of such psychometrically derived theories of cognitive abilities as those of Guttman, Cattell, and Guilford, appeal is made to E. B. Hunt's "distributive memory" model and A. Newell's concept of the "production system" as possible bases for developing an alternative theory. Such a theory of…

Reports the use of a memory load-interference paradigm and the easy-to-hard paradigm as converging operations to study capacity limitations in five- to six-year-old's reasoning. Concludes that transitive inference ability in children is capacity limited. (HOD)

Fifty-five recent studies of individual differences (IDs) in elementary cognitive tasks (ECTs) are reviewed. Twenty-five data sets are examined, analyzed, or reanalyzed by factor analysis. The following promising dimensions are identified: basic perceptual processes, reaction and movement times, mental comparison and recognition tasks, retrieval…

An information processing approach was applied to the development and validation of a test battery intended for personnel selection, classification, and guidance; and design of training programs. The approach specifies that tests should measure specific cognitive processes and basic abilities, rather than prior experience. Tests should be short,…

Proposes the use of procedural task analysis as a tool to assess a person's mental processes during problem solving in science education research. Uses transcriptions of videotape or audiotape problem-solving sessions to identify students' knowledge structures and misconceptions. (MDH)

A new framework for designing qualitative studies is described to optimize the emergence, representation and presentation of insights. The framework, called Reflection Methodology, is presented as a "Conversational Paradigm" that includes four components--interviewer (researcher as participant); child, task situation, and observing…

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…
