As part of a continuing series, this book contains 27 conference papers, which reflect the theme of reading as a process of creating meaning for sensed stimuli. Titles, among others, cover the following topics: (1) writing and reading in a balanced curriculum; (2) the creation and discovery of meaning; (3) learning disabilities; (4) key words and…

Representatives of a variety of disciplines concerned with either clinical or research problems in vision and learning disabilities present reviews and reports of relevant research and clinical approaches. Contributions are organized into four broad sections: basic processes, specific disorders, diagnosis of visually based problems in learning,…

The question of whether pupil diameter indicates information processing load during reading was investigated in three experiments involving 24 college students reading passages of varying difficulty. A TV camera and monitor, together with a video-recorder, were used to measure the diameter of the pupil under a reading condition and under three…

The development of sensory and perceptual ability in infants is an important area of infancy research. This book reflects current knowledge of perceptual development and points to some of the many questions that remain unanswered. The book is divided into four parts. Part 1, "How the Visual System Develops: Normal and Abnormal…

In the analysis of ability structure and loss of vision, 228 blind persons (153 male, 75 female) heterogenous in respect to chronological age, sex, degree of blindness, age at onset, and duration, were compared to sighted controls. A test battery was administered which included tests for verbal comprehension, mental arithmetic, spatial ability,…

Based on the more general principle that all thinking (including reasoning) is basically perceptual in nature, the author proposes that visual perception is not a passive recording of stimulus material but an active concern of the mind. He delineates the task of visually distinguishing changes in size, shape, and position and points out the…

The purpose of the third edition of this book is to explore what must be involved in reading by addressing such topics as language, information theory, learning theory, the development of spoken language ability, and the physiology of the eye and brain. It is designed to serve as a handbook for language arts teachers, a text on the psychology of…
