These studies confirm the view that the "air gap" phenomenon, which refers to the area that remains when ground and sky lines are constructed at the bottom and top of a drawing, is commonly found in the free drawings of middle and later childhood, but that it is readily abandoned when task demands are modified accordingly.

Relatively brief interactions with a commercial game that involved blocks and matching patterns are shown to cause a significant improvement in children's performances on the WISC-R Block Design subtest. Two experiments are described using 10-year-old children in game and no-game conditions. (Author/CM)

Responses of 241 convicts on 18 primary mental abilities were factored to explore the idea that there are organizations among visual and auditory functions that operate independently from the relation-perceiving and correlate-educing functions of fluid and crystallized intelligence. The suggested reliable common-factor functions are discussed.…

Reviews work on three areas of visual information that are available to readers: information provided by the conventional arrangements of the print on the page, by the features of each letter, and by the shapes of entire words. (HOD)

This is a discussion of the conservation of angular momentum of the human body engaged in somersaults and twists. The principle is also applied to a cat turning over in midair. The events occur in the absence of torques. Application of the maneuvers are suggested for astronauts. (SA)

Recent research on visual imagery mnemonic techniques is compared to research in the late 1800s and early 1900s. Results of recent research are discussed in terms of practical implications for education. (Author/MH)

Seventy percent of the children (non-conservers in length) who had to respond to length equality as opposed to inequality made the correct invariance judgment and could characterize their choices in invariance language, while still failing the standard verbal task in which the experimenter used such phrases. (Author/SJL)

Investigated relationships between the Kaufman Wechsler Intelligence Scale for Children-Revised factors, Wide-Range Achievement Test (WRAT) scores, and visual-motor maturation in children referred because of school-related problems. Results indicated significant correlations between Verbal Comprehension and Reading, Spelling, and Arithmetic…

Young children drew two opaque objects placed one behind the other. Over two-thirds of the children drew the objects separately in horizontal or vertical relationships. When drawing an object in a glass beaker, half of the children depicted the object vertically or horizontally separate from the beaker. (Author/DB)

Investigated scoring agreement among three different training levels of Visual Motor Integration Test (VMI) diagnosticians. Correlational data demonstrated high interexaminer reliabilities; however, there were gross errors in precision after raw scores had been converted into VMI age equivalent scores. (Author/RC)

Presents a rationale for studying the visual language of film. Reports on three studies that suggest some tentative answers concerning the manipulation of film and some promising approaches to the study of the medium. (RL)

A diagnostic prescriptive approach using the overhead projector in visual perception and perceptual motor activities is described for 11 deaf multiply handicapped behavior disordered students (9 to 12 years old). (CL)

Describes an investigation comparing visual and auditory clues effect on estimates of speakers' heights and weights, to determine if voice alone conveys as much information as visual clues. The results indicate that the differences between estimates based on photographs and those based on speech recordings are, on the average, very small.…

Stereoscopic photo activities for students are described for the purpose of motivating students in earth science. Included also is the necessary equipment for obtaining the three-dimensional effect. (SA)

A study involving 120 second-grade students with deficiencies in visual perceptual skills was designed to determine the effects of a vision training program on reading test performance. Students receiving vision training did significantly better in tests measuring reading comprehension and word recognition skills than did students who did not…
