The project's purpose was to determine whether attention to the task during testing was a confounding variable in measures of visual perception ability. Samples of 30 perceptually handicapped (PH) and 30 normal subjects (N) were randomly selected from children so classified on the Frostig DTVP, providing they had IQ scores between 85 and 115 on…

The generation of dynamic mental imagery is known to facilitate paired associate (PA) learning in older subjects. Wolff and Levin (in press) have reported that children who were apparently too young to generate mental imagery of this kind did benefit from self-generated motoric interactions involving pairs of toys. Since the result was obtained…

Two experiments are reported in which mismatched sounds and spelling were studied in Dutch pseudo-words used as stimuli in English lexical decision experiments. Results show mismatches in spelling or sound result in longer latencies for Dutch pseudo-words than for their nonword controls, supporting a cooperation model of lexical access. (MSE)

Aphasia implies the loss or impairment of language caused by brain damage. The key to understanding the nature of aphasic symptoms is the neuro-anatomical site of brain damage, and not the causative agent. However, because "Herpes simplex" virus (HSV) encephalitis infection usually affects the frontal and temporal lobes, subcortical…

Purpose: This study examined the cognitive demands of 2 selection techniques in augmentative and alternative communication (AAC), direct selection, and visual linear scanning, by determining the memory retrieval abilities of typically developing children when presented with fixed communication displays. Method: One hundred twenty typical children…

A study examined the status of research on effects of pictorial advertising and areas within the field which need additional work. The method of investigation was based on a model of memory, incorporating emotional, semantic, and episodic processing of information--focusing primarily on constructing a preliminary taxonomy of visual stimuli, a…

The legitimacy of using the criterion of low reading achievement in the study of learning and memory skills with learning disabled children was assessed, based on a comparison of 35 nondisabled students, 15 low readers, and 10 learning disabled high school students. Learning disabilities were defined as encompassing perceptual and/or processing…

This report summarizes research performed at the Universtiy of Kansas that involved several topics related to reading and learning to read, including the development of automatic word recognition processes, reading for comprehension, and the development of new computer technologies designed to facilitate the reading process. The first section…

To observe the relationship of auditory and visual receptive skills to achievement in reading, 80 eight-year-old children were given a diagnostic test battery which examined three receptive skills--attention to stimuli, discrimination, and memory--within three sensory modalities--auditory, visual, and auditory-visual. The control group consisted…

Differences in perceptual processes of good and poor readers relevant to single word perception have been studied in a series of experiments. The major differences between good and poor readers have been shown to occur at the level of the single word; other differences occur in knowledge of spelling patterns and ability to make use of letters'…

A bibliography and selected annotations of research on cognitive style are presented. The citations were retrieved from computer and manual searches of the literature. Selected items, based on their significance to research efforts, are organized around subject, method, and results of each study. Ten constructs are included: (1) field…

This report is part of a general study of Reference Measures for Cognitive and Noncognitive Factors. The main activity being reported is the development of "factor-referenced" or "marker" tests for several recently identified cognitive factors. A secondary activity involves the study of possible relationships to factors already…

This study investigated attention to and recognition of components in compound stimuli among infants and preschoolers. Oddity tasks with preschoolers and familiarization/novelty-preference tasks with infants demonstrated successful discrimination among stimuli components on basis of edge property information. Matching tasks with preschoolers and…

A study explored working memory (WM) capacity, WM task requirements, as well as effects between WM, skills, knowledge base, and intelligence in adults with mental retardation and children aged 3-6 years. Adults were better on measures reflecting skills and knowledge base. Children performed better in phonological and visuo-spatial WM tasks.…

A model of graph comprehension is proposed including perceptual and memory processes. Multidimensional scaling (MDS), cluster analysis, and analysis of variance (ANOVA) were used to determine how college students with different mathematical experience read different types of bar graphs. Data were collected at the University of Oklahoma (Norman)…
