The authors review their work on helping physicaly handicapped persons gain spatial cognition through the interactive graphics learning environment of a computer LOGO system. The findings are said to demonstrate that the LOGO tasks are a viable part of a school curriculum for students with cerebral palsy, as shown by severely/profoundly handicapped students 7 to 8, 11 to 13 and 17 years old. The LOGO system allowed the students a source of experience in visiospatial problem solving. Efforts to develop computer based methods of assessment are discussed. Possible reasons for demonstrated deficits in visiospatial functioning are noted to include lack of experience and the effects of brain damage. The system's role in studying linguistic problems and improving communication skills is considered, and future research topics are listed. (CL)
