Research investigated the utility of an alternative technique for the study of vigilance performance. The usual approach has been to study how well subjects responded to a signal of given difficulty; this technique altered the difficulty of the task to ensure a fixed level of performance. A computer-based, self-adjusting program presented…

This study investigated the spontaneous use of verbal mediators in discrimination learning, the transfer of mediators to a free recall task, and the effects of a pretraining task on performance. The discrimination tasks required nursery school children (80) to: (1) sort three instances each of two different concepts in a conceptually consistent…

The importance of effective communication compels investigators to seek new ways of measuring physiological responses and to practice the science of psychophysiology. The main objective of psychophysiological research is to describe the systems in organisms which transfer information between the subsystems of soma and psyche. Results should lead…

Three experiments assessed the ability of children 2 to 5 years of age to infer, under very simple task conditions, what another person sees when viewing something from a position other than the children's own. Data indicates that some ability of this genre appears to exist by age 2. The data also suggests a distinction between an earlier and a…

An analysis of group social relationships through an interpersonal perception point of view is presented. Each member of a group is asked to make a judgment concerning the social distance between each pair of members in the group. The Carroll and Chang scaling model, called Individual Differences Scaling (INDSCAL), which assumes that individuals…

A study was conducted to determine the relative effectiveness of various techniques of accumulating and organizing images in multiple-screen, slide-tape presentations of geographical information. Identical stimulus materials were presented in five different ways from sequential presentation to accumulated presentation to programed accumulated…

These appendices to ED 043 919 contain the test instrument itself, which was not included with the original announcement. The Attitude to School Questionnaire (ASQ) is designed to measure first graders' attitudes toward school. ASQ is a group-administered, paper and pencil, nonverbal, paced test. The child listens to a description of a situation…

In training people to perform auditory identification tasks (e.g., training students to identify sound characteristics in a sonar classification task), it is important to know whether or not training procedures are merely sustaining performance during training or whether they enhance learning of the task. Often an incorrect assumption is made that…

A pilot study to evaluate the effectiveness of multi-image audiovisual teaching showed this technique to have a definite advantage over conventional single-image audiovisual aids. The multi-image technique involved using two or more visual aids designed to interact with and to amplify each other. Experimental and control groups of college students…

A course that capitalizes on individual and group experiences and encourages students to expand their powers of observation and discernment is presented in the course, students analyzing their thoughts and translate them into written responses. The performance objectives are: A. Given opportunities to experience sensory and emotional stimuli,…

The effects of slide photos on ideational fluency in 240 children in grades IV, VII and IX were studied. Children listed uses of tires and knives and similarities between potatoes and carrots, and cats and mice. It was reasoned that stimula which attract attention too closely to physical characteristics of objects directly under consideration…

Discusses the efficiency of the visual aid in teaching English as a second language. (Author/HP)

This study is based on three distinct elementary cognitive tasks using chronometric techniques: (1) the S. Sternberg memory scan task, (2) a visual scan task; and (3) the Hick paradigm. Certain parameters of the tasks are compared experimentally and correlationally. Subjects were 48 university students, tested and retested on the tasks in a…

A 14-year-old girl, born with a form of brain damage which caused mental retardation and lack of normal speech, progressed from use of basic sign language and picture communication to use of an electronic speech-synthesized communicator for her expressive language needs. (CB)

Fifth-grade learning disabled and skilled readers (N=32) were compared on verbal dichotic listening tasks for free recall and cued recall of word lists organized by semantic, phonemic, and structural features. Results indicated that disabled readers were comparable on free recall but were inferior to skilled readers on cued recall. (Author/JW)
