The relative ease of learning with Bliss symbols or words was investigated using four moderately retarded and four severely retarded children (ages 6 to 9 and 14 to 17, respectively) as Ss. It was found that Bliss symbols were the more easily learned and this was most evident among the severely retarded Ss. (Author/PHR)

The effects of prompting and confirmation on automated presentation of materials in discrimination learning were studied. Eight pairs of words or pictures were presented to 48 mentally retarded subjects (mean IQ 63, mean chronological age 163.4 months, mean mental age 103.3 months). Each subject's correct responses advanced the program and, in the…

Presents study showing children with behaviors characteristic of attention disorder/hyperactivity deficit and high intelligence have more mixed laterality and allergies. Finds these children gather and use more diverse nonverbal and poorly focused information. Concludes such children use uncommon information when exhibiting novelty in nonverbal…

Three experiments tested whether qualitative differences in processing of verbal materials result from congenital hearing impairment. Subjects were children with reading levels equivalent to grades 4 to 6. Experiment 1 used repeated measurements with two modes of response and two kinds of cues; experiment 2 used acoustic similarity to produce…

To test the hypothesis that the amount learned from a manipulative, nonverbal oriented unit on electricity would be better predicted by a learning potential assessment procedure than from an IQ based classification (educable mentally retarded status), an EMR group and a regular class non EMR group were both exposed to the unit; untaught EMRs…

In order to determine the differential ability of mildly retarded school children to profit from coaching on non-verbal, non-academic reasoning problems and to study their problem solving and conceptual behavior, the Raven Coloured Progressive Matrices Test was given to 72 educable students (IQ 55 to 80) in socioeconomically homogeneous suburban…

Using a 41-test battery of cognitive-perceptual-motor tests supplemented by standardized tests of intelligence, visual perception, eye hand coordination, linguistics, and non-verbal integration, a group of 200 maladjusted school age children from grades 1, 2, 3, and 5 was compared with a group of problem-free children similar in size, sex…
