The basis of young children's performance of judgments of recency and frequency was investigated using a modified version of Huppert and Piercy's [Huppert, F. A., & Piercy, M. (1978). The role of trace strength in recency and frequency judgements by amnesic and control subjects. Quarterly Journal of Experimental Psychology, 30, 347-354]…

How long does it take to form a durable representation in visual working memory? Several theorists have proposed that this consolidation process is very slow. Here, we measured the time course of consolidation. Observers performed a change-detection task for colored squares, and shortly after the presentation of the first array, pattern masks were…

Forty-seven third grade regular class boys rated as disruptive by teachers were administered three tests to determine incidence of perceptual deficits as well as effects of race and social class on auditory discrimination. (MC)

Describes an experiment measuring response latency which required subjects to make a word-nonword decision in response to a visually presented item. (AM)

Individuals previously identified as language-bound (LB) and language-optional (LO) participated in a series of experiments to study verbal fluency. The two groups showed a striking similarity in the number of responses they produced for categories with constraints at various levels (word form, word content, sentence, interpretation). This…

The purpose of this study was to investigate the development of organizational processes for both verbal and spatial stimulus materials within an information processing framework. Children in grades 2 and 4 and adults were tested for their ability to report letter strings reflecting various orders of approximation to English and various dot…

A group of 34 subjects each with a reading deficiency of 1 year or more were studied on the following variables: visual perception, arithmetic, memory, auditory perception, and laterality. The age range was from 8 to 13 years, with a mean grade deficiency of 1.93 years. Using the Minnesota Percepto-Diagnostic test as the diagnostic instrument, the…

Reminiscence, or an increase in retention scores from a short-to-long-term retention test, has been shown in some previous work to be a significant function of arousal. Previous studies of the effects of color versus black-and-white audiovisual presentations have generally used film or television and have found no facilitating effect of color on…

The Benton Visual Retention Test which is designed to assess visual perceptual, visual motor, and visuoconstructive abilities can give school personnel greater precision and range in testing. The standardization of this instrument was tested on 700 Houston elementary school students. Chronological age differences were maintained and correlation…

Presented is a curriculum designed to provide the teacher of the young deaf child with learning disabilities with a description of developmental objectives and methods for fulfilling these objectives in the areas of gross motor development, sensory motor integration, visual analysis, attention and memory, and conceptualization. The objectives are…

Experiments tested the predictions that words are perceived more accurately in strongly constraining word contexts than in weakly constraining word contexts, and that a strong perceptual advantage would be present for letters in words vs. letters alone or in unrelated-letter strings. Several alternative theories of word perception are discussed.…

Explores the effect of continuous training on tonal and auditory memory. Does so by comparing the auditory short-term memory skills of English and American children, ages five, six, and seven. (RKM)

The spread of encoding concept was tested visually by having subjects view pictures which varied in contour completeness. The hypothesis was supported that as contour completeness decreased, the amount of perceptual analysis and memory performance would increase. (Author/MH)
