Analyzes a method of detecting changes in a particular frequency band by evaluating the overall shape or profile of the auditory signal spectrum. Claims that profile analysis is different from intensity discrimination, and applies the new method to detecting noise sinusoid and to results obtained when signal frequency is uncertain.

Focusing primarily on learning disabled children, the article briefly reviews the literature related to perceptual skills required in reading acquisition and the validity of current perceptual measures to tap these task-related perceptual abilities, and proposes an informal task-related measure to overcome the drawbacks of more formal measures of…

Meanings given to the term "perception" are discussed in this paper and two categories of perception theories having implications for instructional media research are identified. One category is described as extroverted because it includes theories primarily concerned with characteristics of external stimuli and the influence that the…

Describes formal and informal techniques used to evaluate young children's cognitive style for the purpose of individualizing instruction. Topics include controlled laboratory procedures, paper and pencil tests, classroom assessments, and individualization in educational programs. (RJC)

Reviews Gibson's contributions to the domain of perceptual learning, including her classic experiment concerning the perception of scribbles. Discusses Gibson's research on differentiation and the links between perception and learning, the status of her research and ideas, and her experimental approach. (BG)

This paper reviews the research literature regarding the importance of Witkin's theory of psychological differentiation, particularly the research on measures of field independence using perceptual disembedding tasks. The first phase of development of a multiple-choice perceptual disembedding measure, the Finding Embedded Figures Test, is…

The author discusses the role of perceptual training in the education of young perceptually handicapped children. Distinctions are drawn between perception and awareness, and the necessity of stimulation to encourage infant and child learning is emphasized. Commonalities between perception and learning are underscored. The author stresses that…

The perceptual responses of individuals at different levels of physical fitness to absolute exercise intensities were compared. Perceived exertion, as measured by the Rating of Perceived Exertion scale, did not discriminate between subjects who were physically fit and those who were not, despite differences in physiological strain.

The article provides a table of the 50 most commonly used assessment instruments for use with visually impaired individuals. Cognitive, achievement, reading, mathematics, spelling, language, listening/auding, perceptual motor, early childhood, and career education tests are reviewed. (Author/SBH)

The paper reviews studies of field articulation, that is, dimensions of field dependence-independence in social as well as perceptual domains. Field independence, one's ability to isolate an item from its surroundings, is contrasted with field dependence, manifested in one's difficulties analyzing and focusing on specific aspects of a task. The…

Cognitive style refers to preferences for, or dominant modes of, information processing. Cognitive styles tend to be bipolar and less value-laden than ability or aptitude measures. Conceptualizations of cognitive style differ in the number of styles and the degree of metacognitive control over them which individuals are presumed to have. The Hill…

Studies investigating the functioning of persons who have cerebral lesions and evidence from the study of commisurotomized and normal subjects are reviewed. A study of recognition of pictorial stimuli by right-handed male children is also discussed. Studies about cerebral lesions and associated deficits have yielded information about the…

The nature of the cognitive style of field articulation and its relationship to differentiation of personality are discussed. A short historical summary of research on field dependence-independence is presented, and problems of measurement, stability, and evolution of the dimension of field articulation are discussed. The connections between field…

This manuscript was written to provide rehabilitation professionals, and vocational evaluation practitioners in particular, with information about learning style assessment instruments. The first section of the guide consists of a literature review that focuses on such aspects of development of the learning styles concept as individual…
