Analyzes the task performance of two groups of readers--those who made gains and those who did not make gains in a remedial reading situation in order to determine their use of word identification cues. Shows that the gain group was more analytical of the test words and tended to use more units of varying size. (HOD)

Examines the relationship of achievement in reading, spelling, and arithmetic with a variety of other measures, including tests of visual memory and visual-motor association. Concludes that visual association is more closely related to achievement in reading, arithmetic, and spelling than is visual memory. (HOD)

The generative learning model is explored and linked to recent science education research findings. The implications of the model for the teaching and learning of science, the training of science teachers, and science educational research are discussed. (JN)

Reviews causes of dementia in later life, especially the Alzheimer's type, its prevalence, the characteristic structural changes, and hypothesized causes. The hypothesis that Alzheimer's disease represents accelerated aging is described. Treatment issues are discussed, primarily in terms of supportive environments, differential diagnosis, and…

Two groups of undergraduates differing in reading ability were tested on a number of reaction-time tasks designed to determine the speed of encoding visual information at several different levels, tests of sensory functions, verbal and quantitative reasoning ability, short-term auditory memory span, and ability to comprehend spoken text.…

Studied the extent to which memory and processing speed accounted for relations between infant information processing and childhood IQ. Found that the relationship of 7-month visual recognition memory and 1-year cross-modal transfer to 11-year IQ were reduced when statistically controlled for factors derived from these measures, suggesting that…

A growing body of empirical and theoretical work indicates that young children (grades K-3) have difficulties solving word problems because of deficient language and text comprehension strategies. Describes a computer simulation designed to model working memory demands in "bottom-up" comprehension of arithmetic word problems, offering a…

Two experiments investigated whether young and old adults can temporarily remove information from a capacity-limited central component of working memory (WM) into another component, the activated part of long-term memory (LTM). Experiment 1 used a modified Sternberg recognition task (S. Sternberg, 1969); Experiment 2 used an arithmetic…

Dramatic changes in our science in recent years have profound implications for how psychologists conceptualize, assess, and treat people. I comment on these developments and the contributions to this special series, focusing on how they speak to new directions and challenges for the future of CBT. Discoveries about mind, brain, and behavior that…

This study deals with the demand of a task. A theoretical background shows the difficulty of applying the idea of demand (as established in the literature) to the data. This has been confirmed in the preliminary study of this paper, which deals with the analysis of university examinations. Some factors that affect the demand of a task have been…

This book provides an introduction to the current scientific understanding of the human brain and its processes. Chapter 1, "At the Edge of a Major Transformation," is an introduction to the field. Chapter 2, "How Our Brain Organizes Itself on the Cellular and Systems Levels," covers what body/brain cellular systems do, how…

Chapters in this textbook for college students in introductory psychology courses are: (1) What is Psychology?; (2) Scientific Methods in Psychology; (3) Biological Psychology; (4) Sensation and Perception; (5) Altered States; (6) Learning; (7) Memory; (8) Cognition and Language; (9) Intelligence and Its Measurement; (10) Development; (11)…

This study examined the relation of reading ability, age, and familiarity to iconic and short-term memory processing and how the familiarity of the stimuli affects recall. A total of 10 children in grades 2 through 6 and 10 adults were shown novel abstract forms, words, and non-words varying in order of approximation to English, for 50 msec., 500…

This report describes a simulation of adults' retrieval of arithmetic facts from a network-based memory representation. The goals of the simulation project are to: demonstrate in specific form the nature of a spreading activation model of mental arithmetic; account for three important reaction time effects observed in laboratory investigations;…

Three experiments, in which subjects read passages of variable readability, measured "cognitive capacity usage" (the attention level to reading material) by recording by subjects reaction times in a secondary task (responding to a "click"). The data indicated that the easy texts filled cognitive capacity more completely than the difficult texts,…
