More than 100 college students enrolled in a reading and study skills course participated in a study designed to show the effects of retrieval speed on adult reading comprehension. A microcomputer version of the Posner task was used to measure memory retrieval speed, and reading and listening comprehension were measured from McCall-Crabbs…

Two experiments investigated children's strategies for solving geometric matrices that were correctly or incorrectly completed and that varied in number of elements and number of transformations. Examining the relationship between working memory and item complexity, the first experiment tested 90 boys and girls of 7, 10, and 13 years of age for…

A model of how automated and controlled processing can be mixed in computer simulations of problem solving is proposed. It is based on previous work by Hunt and Lansman (1983), who developed a model of problem solving that could reproduce the data obtained with several attention and performance paradigms, extending production-system notation to…

Undergraduates (n=99) differing in spatial ability were tested on problems involving the mental rotation of familiar alphanumeric stimuli and unfamiliar stimuli drawn from the Primary Mental Abilities Space Test. Individual differences in spatial ability were associated with speed rather than accuracy of mental rotation processes. Ability…

Using between subject designs, Tversky and Sherman (1975) and Weaver (1974) demonstrated that increases in the blank interval (offtime) separating two successive pictures leads to improved performance on retention tests. If this improvement results from active rehearsal strategies, subjects should be able to differentially rehearse pictures cued…

A theory of discrimination which assumes that subjects compare psychological values evoked by a stimulus to a subjective referent is proposed. For a related article, see TM 501 716. (Author/RC)

This project designed and developed a specialized student skill module for providing rudimentary time management skills, and implemented and evaluated the effectiveness of this skill module for reducing course completion times and promoting positive student attitudes in the context of a computer-based progress management system. Evaluation…

This paper reports two experimental studies of the development of time, speed and distance concepts in children. In Experiment I subjects (12 in each of four age groups: 5-, 8-, 11-year-olds, and adults) were asked to judge which of two electric trains on parallel tracks went faster, for the longer distance, or for more time. Subject's knowledge…

A sequence of reasoning processes based on a combination of theories developed by Jean Piaget is presented. An applied theory of concept-teaching is derived from the restructuring of Piagetian theories on logical thought specifically concerned with the notions of the additive and multiplicative ordering of groups, and the four logic processes of…

Two experiments related to the development of verbal self-control in children were conducted. In the first experiment, 36 adults and 36 four year olds were administered a vocal alone, a motor alone, and a combined-reaction-time task. In the second experiment, 54 kindergarten subjects and 60 fifth-grade subjects were each administered a double…

This study investigates the relationship between temporal organization and the rate at which discrimination-reversal learning mastery occurs within sixth-grade students. Subjects were 22 male and 30 female students from a predominantly white, middle class rural school. Temporal behavior was assessed with a task that had subjects reproduce standard…

Reports the results of a high-speed search task administered to overactive and distractible (hyperactives), normoactive and distractible, and normoactive and attentive (controls) children. Instructions emphasized speed, accuracy, or both speed and accuracy. Indicates that controls and distractibles conformed to the fast guess model, which relates…

Measures of verbal intelligence and abstract reasoning were taken on a group of 31 college-aged and 32 elderly adults, together with mental-processing rates associated with choice reaction time, primary memory scanning, and lexical decoding. Group means showed that verbal IQ and lexical decoding were intact in the elderly subjects. (Author/LMO)

The data indicated that disadvantaged children required more time to process visual information than did middle-class children, but the processing speed for the 2 groups tended to become more similar as grade level was increased. (Author)
