To increase the efficacy of visual instruction, more must be known about the operational forces within the image, and the determining factors in picture quality as a means of communication. The theory of information applied to this analysis of pictorial content, the fundamental thesis being that the value of an image depends on its content of…

The purpose of this study was to see if a change in environment affected the rate of sensorimotor development in infants. First a control group of institutionally-reared infants aged 1 to 6 months was observed to determine average age of visually directed reaching, visual exploration, visual accommodation, and the blink response. Then the…

The purpose of this study was to determine the relative effectiveness of pictorial drawings and scale models in teaching principles of orthographic projection. A sample of 60 students were randomly selected from a population of sixth grade boys in four Minneapolis public schools. They were divided into three IQ levels and assigned to four groups:…

This paper examines the development of visually evoked EEG patterns in retarded and normal subjects. The paper focuses on the averaged visually evoked potentials (AVEP) in the central and occipital regions of the brain in eyes closed and eyes open conditions. Wave pattern, amplitude, and latency are examined. The first section of the paper reviews…

It has been suggested than an educational curriculum should include training in working with people as well as with ideas. Measuring and conceptualizing "social intelligence has been difficult, however. Although the idea of social intelligence has a long history, most tests which have been proposed to measure such ability correlate highly…

Special equipment was used to record the eye movement patterns of 60 children enrolled in a reading clinic. There were 20 children in each of three groups: good readers, slow readers, and non-readers. The children were shown printed material on a screen accompanied by action sequences and voice recordings similar to what they might see on…

One hundred twenty-eight observers randomly assigned to 16 treatment conditions in a modified Latin square design, viewed three videotapes of simulated classrooms in which teacher behavior was controlled (paralleling psychophysical procedures) to fit unambiguously into specific categories on ratings of frequency and variety of social…

This volume reports an effort to use the video media as an approach for the preparation of a battery of symbolic tests that would be empirically valid substitutes for criterion referenced Job Task Performance Tests. The graphic symbolic tests require the storage of a large amount of pictorial information which must be searched rapidly for display.…

The Mackworth wide-angle reflection eye camera was used to record the position of the gaze on a display of 16 white symbols. One of these symbols changed to red after 30 seconds, remained red for a minute of testing, and then became white again. The subjects were 10 aphasic children (aged 5-9), who were compared with a group of 10 normal children,…

Twenty children in each of grades 2 and 4 were given a reaction time task of the type in which Sternberg (1969) shows high-speed, serial, exhaustive scanning of information in memory. On each trial subjects were asked to memorize two, four, or six pictures and were then presented with a single picture probe. The subject made a key-pressing…

The Connecticut School program for migrant children which was conducted during the summer of 1968 implemented several innovative projects. Among these were dietery aides, visual stimulation for oral development, and parental participation. Ancillary services were also provided by the program; it was found that a large number of children, mostly…

Two experiments comprised this study comparing the ability of children from ages 4 to 12 years to discriminate the order in which items from a previously presented sequence of stimuli had been presented. The hypotheses were that the discrimination of recency (DR) improves with age, that broader separations of test items are easier to discriminate…

In order to investigate developmental changes in multiple classification, a matrix task was administered to 80 kindergarten first, second, and third grade children. Correct solution of the incomplete matrices, comprised of three pictures in a row and three pictures in a column meeting at a blank intersection, required identification and…

This study investigated methods of assessing the effects of cultural deprivation in relation to school adjustment. The investigators developed new methods of assessment in areas of self-concept, (sample of 49 children) concept formation, (314 children) and value orientation, (45 children) The Peabody Picture Vocabulary Test (sample of 60 children)…

Professional workers can assist parents of retarded infants by (1) helping them to recognize and cope with their feelings of guilt and despair, and (2) establishing a home program of exercises to allay the infant's inertia. Such exercises have been demonstrated by numerous investigators to be of positive value in improvement of motor performance.…
