The study was conducted to determine if learnings of spatial perception can be increased by the utilization of motion information experiences as measured by perceptual tests of voluminality and visualization. Perceptual change was specifically examined regarding the use of depth in paper sculpture production and the use of spatial relations in figure-completion tasks.The study's research design consisted of 77 white, lower-middle-class, fourth-grade subjects used as intact classroom groups of two pretest-posttest treatment groups, one pretest-posttest control group and one posttest-only control group.Two experimental treatments incorporating different instructional methods were implemented to promote perceptual change in subjects. One treatment provided for motion information experiences by depicting continuously changing views of several sculptures in a motion picture film. The motion information treatment also contained a monocular depth cue explanation which was applied to the film and assisted by manipulating the film projector's action. The treatment was contrasted with another which utilized stationary information presented in photographicslides indicating three views of each filmed sculpture. Since this stationary information treatment used the same procedures regarding depth cue instruction and discussion, it served to isolate the motion variable found in the other treatment. The pretest-posttest control group received no treatment but the posttest-only control group experienced the same visual and verbal communication contained in the motion information treatment.The instruments that measured pretest and posttest achievement were a Voluminal Form Test (VFT) devised by the investigator and the Spatial Relations Test (SRT) from the Primary Mental Abilities series. The former test was used by trained judges to determine the degree of voluminality displayed in sculptures produced by the research subjects. Subject's visualization ability was measured by the standardized SRT.The nonrandomized subject's scores were processed by an analysis of covariance procedure that adjusted the respective posttest group means of the pretested groups. The adjusted means were then utilized in t tests. An analysis of variance procedure was also conducted between the unadjusted posttest means of the motion information treatment group and the posttest-only control group.Results of the t tests that used VFT and SRT scores indicated nonsignificant differences existed between the three pretested groups. The differences between the motion information treatment and the unpretested control groups were also not significant, judging by ANOVA's results. These results were found regarding both voluminality and visualization data.Based on the conditions, methods and findings in the study, four conclusions were inferred concerning hypothesized change in subject's spatial perception as demonstrated in either sculpture production or visualization test performance.1. Visual motion information experiences analyzed through monocular depth cue utilization training did not affect greater spatial perception than did identical training using stationary information experiences.2. Improved spatial perception was not more affected by visual motion information experiences analyzed through monocular depth cue utilization training than by a nonvisual information-and-training experience.3. Training consisting of visually stationary information experiences analyzed through monocular depth cue utilization did not affect increased spatial perception as compared to such effects associated with a nonvisual information-and-training experience.4. When analyzed through monocular depth cue utilization training, pretested visual motion information experiences did not affect greater spatial perception than did nonpretested, but otherwise identical, motion information experiences.Due to possible validity threats from an irregularity in the procedures and the use of nonrandomized subjects, the last conclusion regarding pretest sensitization was most cautiously offered.
