In two experiments, first and fourth grade subjects performed a speeded card sorting task with either integral or nonintegral dimensions. The dimensions were arranged so that subjects sorted on three types of task: (1) single dimension, (2) correlated dimensions, and (3) orthogonal dimensions. (Author/MS)

Examines the articulation of theoretical issues in learning that is taking place through studies of instruction that are grounded in descriptions of competence. Discusses programs for the acquisition of proceduralized knowledge, the development of self-regulatory strategies, and the structuring of knowledge for problem solving. (JS)

The cognitive revolution began in the 1950s as researchers began to move away from the study of knowledge acquisition and behaviorism to the study of information and the way it is processed. Four factors are discussed in chapter 1 as contributing to the increase in popularity of the "cognitive revolution" (increasing enthusiasm for the…

There is increasing debate over the unidimensionality of the construct "drive" in theories of behavior. The earliest drive theory postulated a simple entity which increased or decreased as a function of external or internal stimulation and affected behavior monotonically. Duffy and Malmo have recently hypothesized that the effects of…

Two experiments examined pigeons' generalization to intermediate forms following training of concept discriminations. In Experiment 1, the training stimuli were sets of images of dogs and cats, and the transfer stimuli were head/body chimeras, which humans tend to categorize more readily in terms of the head part rather than the body part. In…

In people with velo-cardio-facial syndrome [or 22q11.2 deletion syndrome (22qDS)], a single interstitial deletion of chromosome 22q11.2 causes a wide spectrum of cognitive deficits ranging from global learning difficulties to specific cognitive deficits. People with 22qDS are also at high risk of developing attention-deficit hyperactivity disorder…

In an effort to create a multilevel, interactive, and hypothesis-based model of the reading comprehension process that bridges interdisciplinary gaps in the theory of learning, this report focuses on descriptions of cognitive processes developed in the fields of cognitive psychology, artificial intelligence, sociolinguistics, linguistics, and…

The Multidimensional Behavior Rating Scale (MBRS) was constructed to assess symptoms of depression across seven modalities: behavior, affect, sensation, imagery, cognition, interpersonal relationship, and drugs. Subjects (N=33) were matched by level of depression on the Minnesota Multiphasic Personality Inventory Depression Scale to either a…

A brief review of the history of cognitive style research and a summary of definitions and terminology used by investigators in the area are presented. Most of the research on cognitive style has been motivated by work from three major groups: Witkin and associates; Holzman, Gardner, and associates; and Kagan and associates. Various definitions of…

One control group and eight experimental groups, each composed of 12 first grade children, participated in this experiment. It was designed to investigate the effects of frequency of reinforcement and repeated evaluation of stimuli on the conditioning of preferences. Each child participated in the experiment for seven consecutive school days. The…

Three students (ages 17, 19, and 21) with moderate disabilities were taught to read and match-to-sample sight words comprising 4 4-member stimulus sets. Student performance indicated that symmetric relations emerged before one-node transitive relations and that one-node transitive relations emerged before two-node transitive relations. Results…

Explores Maria Montessori's notion that a young child's brain is significantly different from an adult's and that young children develop according to a series of predictable "sensitive periods." Cites numerous empirical studies that support these and other ideas Montessori postulated without the advantage of sophisticated scientific…

One cognitive theory of spelling states that the spelling of words can be produced in one of three ways, depending on the amount and kind of information stored in the memory about a particular word. Assuming this theory as a foundation, this study reviewed two forms of computer assisted instruction developed in an effort to build an instructional…

Several psychological theories are viable when examining the victims of intimate violence, specifically battered women. Although cognitive consistency models view individuals as striving toward balanced cognitive states, battered women can exist with the cognitive inconsistency of being harmed by men who love them. The theory of cognitive arousal…

A conception of the self system is needed for studying personally involving beliefs and attitudes, particularly to interpret research findings that show differences in cognitive processing and action as a function of varying levels of involvement. Different levels of involvement are associated with different structures of attitudes and beliefs, as…
