Two-letter stimulus displays, differing in the magnitude of the horizontal spatial separation between the letters, were presented tachistoscopically to 10 retarded and 1 nonretarded adults. (Author/CL)

This study is a detailed analysis of the course of habituation of preschool children to visual stimuli using behavioral measures as data. (Author/SB)

Three experiments contrasted subjects' memory for verbal and figural displays. Data are discussed in terms of a multiple coding model, which is suggested as a more fruitful approach than single-code models such as those proposed by Pylyshyn or Anderson and Bower. (Editor/RK)

Marks (1973) and Gur & Hilgard (1975) have reported success in predicting performance in visual-memory tasks from scores in a questionnare of self-rated vividness of imagery, i.e. the Vividness of Visual Imagery Questionnaire (VVIQ; Marks, 1973). These findings were disconfirmed in two experiments in which the VVIQ was used and vivid pictures…

Described is a prosthesis that connects a television camera and associated circuitry to the visual centers of the brain to restore a limited amount of visual sensation to totally blind persons. (Author/MH)

The influence of stimulus number and familiarity on judged duration were investigated. Results showed that the number of stimulus elements presented within a given interval affected its perceived duration, although the familiarity of those elements (as defined herein) did not. (Editor/RK)

This study tested the assimilation of an auditory-visual stimulus configuration in 32 infants aged 15 to 16 weeks. The infants' discrimination of matched and mismatched auditory-visual stimuli indicated that infants by 4 months of age are capable of constructing bimodal schemata. (JMB)

In order to determine the ability of children aged 3-8 years to reproduce patterns of different levels of complexity, 60 children were asked to reproduce checkerboard patterns at 3 levels of complexity, measured by code length as suggested by H. A. Simon. (Author/SB)

The article examines evidence of visual impairment caused by excessive amounts of ultraviolet (UV) light. Among considerations when using a source of UV light for vision stimulation are the position of the child and teacher, use of window glass filters or protective glasses, and careful recordkeeping of all UV stimulation. (Author/JW)[

A discussion of the many ways that audiovisual aids can support language instruction concludes that the use of audiovisuals is intimately tied to the conditions under which instruction takes place. (MSE)

Examines effects of audio and visual redundancy on recall and story understanding in television news. Indicates that college students who viewed voice-over news stories varying in amount of redundancy showed higher auditory recall and story understanding in the high-redundancy condition than in the lower redundancy conditions. Visual recall shows…

Four reproducible pages containing activities to help children understand the effect of television, to question what they watch, to study how they use television, and to explore aural and visual awareness. (MT)

Discusses the importance of photo spreads for enhancing follow-up coverage of a student newspaper or yearbook. (JK)

A new theory linking information extraction patterns to the visual perception of direction and extent is presented. Seven demonstration experiments employ predictions from efferent considerations to create a new set of illusions of direction and extent and to demonstrate new predictable variations in the magnitude of some classical illusion…
