A comparison of test results on the Visual Discrimination Test was made between a group of 22 reading disabled children and 22 children who were reading on or above grade level. Both groups were of average or above-average intelligence and the two groups were matched for age and sex. The mean age was 10 years and 3 months and all the reading…

Visual and auditory stimuli were presented to children to measure symbol processing abilities. Slides which required matching the similarities in two objects in a group of three were presented. At times the matching criteria varied between function, color, and form. Reaction time was quicker when matching by color than by function, which was…

The aim of this study was to assess the length of latencies or reaction times that it took for 15 teachers and prospective teachers to judge the degree of "ethnic-nonstandardness" or "confidence-eagerness" in a child's speech. A set of 2-minute video-tapes made from interviews with six 11 and 12 year old boys from six ethno-status groups--Black…

Fifth-grade and college students in two experiments listened to tape-recorded sentences and completed tests of immediate recall. The first experiment investigated the effect of a listener's expectations upon his understanding of a sentence. Sometimes the "most probable" answer was not congruent with the "correct" answer, suggesting that the…

A project was undertaken to carry out experimental and methodological investigations on learning phenomena and psychometric methods relevant to instructional technology and computer-assisted instruction. The project's accomplishments are presented in this report, along with a listing of reports and products produced. The work of the project is…

Two experiments evaluated the effects of mnemonic training upon 5- and 10-year-old children's learning and retention of patterns at varying intervals. Subjects were 172 middle class children evenly distributed across the two age groups. Experiment I investigated the effects of individual strategies (perceptual exploration, organization of…

Describes ways in which educators are using microcomputers to teach special education students basic skills and to handle paperwork demanded by legal regulations. A comparison of Individualized Education Program (IEP) software packages currently available and a profile of a Louisiana school district's special education network are included. (MBR)

This study investigated the relationship between measures of speed of cognitive information processing and intelligence test scores. Cognitive processing measures were significantly related to IQ scores. Reaction time tests measure cognitive operations basic to intelligence, and individual differences in intelligence are partly due to variability…

Predictors of retrieval times produced by students having difficulty developing a reliance on retrieval for simple addition were discovered. The findings support the notion that separate limitations operate in working memory when retrieval occurs and call into question the use of the term "retrieval deficit" to explain difficulties…

Verbal coding and listening comprehension ability differed among skilled and less skilled readers in second, third, and fifth grades. As verbal coding speed increased, comprehension skill became the more important predictor of reading skill. Apparently, verbal coding processes, which are slow, inhibit other reading processes.

A cue-target visual attention task was administered to 25 children (ages 10-12) with dyslexia. Results showed a general pattern of slower responses in the children with dyslexia compared to controls. Subjects also had longer reaction times in the short and long cue-target interval conditions (covert and overt shift of attention). (Contains…

Experiment 1 suggested that age differences in line-drawing interpretation among subjects between 6 and 24 years reflected changes in short-term memory for features and changes in strategies used to integrate features over space and time. Experiment 2 suggested that older observers were more active in their attempts to interpret drawings and that…

A new model is presented that explains reaction time fluctuations in prolonged work tasks. The model extends the so-called Poisson-Erlang model and accounts for long-term trend effects in the reaction time curve. The model is consistent with Spearman's hypothesis that inhibition increases during work and decreases during rest. (TJH)

Four students, aged 15-19, with moderate mental retardation learned to cash checks and use an automatic teller through either a decreasing prompt hierarchy or time-delay procedure. Both strategies led to acquisition of target tasks and were equally effective in producing performance maintenance; however, the decreasing prompt hierarchy was more…

Reports five experiments; the first two assessed the effect of the selectional restriction requirements of verbs and the animacy of nouns on sentence comprehension, the third determined the cause of the interaction found in the first set of studies, and the fourth and fifth were self-paced reading experiments.
