Thirty learning disabled and thirty nondisabled children (mean age 10 years) were compared on a paired associate learning task that simulated the process of sight word learning. Two instructional variables (response competition and stimulus complexity) that have been hypothesized as contributing to overloading in learning disabled children, were…

In a visual recognition masking experiment, a target stimulus to be identified is either preceded or followed by a second stimulus called a masking stimulus. The experiments described here provide estimates of both developmental and aging differences in visual backward masking under conditions which maximize interference in the central visual…

Three experiments were performed in which subjects were exposed to two sizes of the Embedded Figures Test (EFT), and subjects in the third experiment were also exposed to two sizes of the Rod and Frame Test (RFT). In the first experiment, where the EFT had a size differential of 1 to 4, a nonsignificant size effect and a significant rank…

The cooperative Navy/Air Force project described is aimed at the problem of image-flutter encountered when visual displays that present computer generated images are used for the simulation of certain flying situations. Two experiments are described which extend laboratory work on delay compensation schemes to the simulation of formation flight in…

Perhaps due to misunderstandings of the nature of the research task in visual communication, findings of empirical research in that field have been highly inconsistent. Historically, there has been little serious systematic empirical investigation of visual communication. One difficulty is that it is not always possible to measure nonverbal…

Nonverbal behavior is an important aspect of the film and is one of the several tools that a director uses to communicate to an audience the characters' feelings and relationships. By adding to this information their own personal responses, viewers often experience strong feelings. With reference to the social psychological research of nonverbal…

An experiment tested the hypothesis that the outcome of a vocal nonverbal persuasion attempt can be affected by the participants' skills in nonverbal communication. Subjects' vocal sending or decoding abilities were pretested. Senders and decoders (N=54) were agents and recipients of social influence, respectively, in a field experiment in which…

A familiarization procedure was used in two experiments investigating word encoding in second and sixth graders. Previous studies using release from proactive inhibition had indicated that developmental changes on some encoding dimensions occur during this period. It is argued that the dependence of release from proactive inhibition on deliberate…

When designing a computerized drill and practice lesson, the teacher should (1) select the content and processes of the lesson to match the content and processes of the initial instruction, (2) present a variety of stimulus presentations for an item, (3) select constructed or non-constructed response modes by the type and complexity of the…

AN INFORMATION TRANSMISSION MODEL THAT ADVOCATES LEARNING VIA ONLY ONE SENSE MODALITY (E.G. VISUAL) IS THE BASIS FOR SEVERAL SERIES OF EXPERIMENTS, EACH SUBJECTED TO RIGOROUS STATISTICAL ANALYSIS. CONCLUSIONS ARE--LEARNING IS NOT FACILITATED BY REDUNDANT INFORMATION PRESENTED SIMULTANEOUSLY THROUGH THE AUDITORY AND VISUAL SENSE MODALITIES, IT IS…

AN EXPERIMENT TO DETERMINE EFFECTIVENESS OF VISUAL (VI) AND VERBAL (VE) PROGRAMED PRESENTATIONS ALSO VARIED RESPONSE MODE (ACTIVE VERSUS PASSIVE) AND ORDER OF PRESENTATION OF VI AND VE VERSIONS OF A SCIENCE LESSON FOR 200 GRADE 8 STUDENTS, TAUGHT VIA CLOSED CIRCUIT TELEVISION, THE FACTORIAL DESIGN REQUIRED EXPOSURE TO ONE LESSON VERSION, IMMEDIATE…

Visual field theory was examined insofar as television viewers' perception, retention, and preference for still visual images were concerned. The purpose of the experimental investigation was to determine whether the specific shapes, colors, and placement of visuals within a picture frame affected viewers' abilities to perceive, describe, and…
