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.…

This paper examines the developmental stages of haptic perception (the process of recognizing objects by the sense of touch alone), and attempts to clarify some conflicting results of studies of the effects of memory and object type. The paper also presents a specific study of haptic perception in 144 preschool and kindergarten children from…

INSCAL multidimensional scaling, an objective methodology for formulating effective technical information sequences for computer-assisted instruction, was shown to be of value with respect to defining the information complexity of technical material, developing sequences of key concepts within technical material, and providing an index of expert…

A highly interactive multicamera-multimonitor closed circuit television system is described which permits a resource room teacher and her handicapped elementary school students to be in continuous visual communication with one another. On the basis of relatively short-term observation, data is reported to show that the system is of most help to…

This experimental study has three aims: (1) to give a detailed description of imitative behavior as it develops during the first six months of life; (2) to compare imitative responses perceived through visual, kinesthetic and auditory modalities; and (3) to describe and explain the regulating mechanisms and processes present in the early…

The problem of structuring sequences of instructional stimuli such that learning is optimized is modelled as a sequential decision problem with an imbedded mathematical model of learning providing a criterion function. Three types of optimization methods for such a representation are investigated for the specific case of paired-associate learning…

The aim of this study is to investigate the effects of noise on the performance of simultaneous conference interpreters, and to carry out a detailed examination of verbal and temporal aspects of their output in relation to source language input. A further aim is to compare the relative effectiveness of simultaneous and consecutive interpretation…
