Depth perception of elementary school students with qualitatively evidenced locomotor impairments.
The purpose of the study was to examine differences in depth perception of students classified according to their gross locomotor skills. The seven qualitative gross locomotor tasks of Ulrich's Test of Gross and Motor Development were used to classify 162 students as either motor impaired (n1 =27) or nonimpaired (n2= 135). The Howard Dollman Apparatus was used to measure depth perception. Analysis showed that the motor-impaired group scored significantly lower than the nonimpaired group on depth perception. Discriminant function analysis indicated that only the running task separated the students by depth perception scores. Subsequent multiple regression analysis confirmed that the running task, along with sliding and galloping, were significant predictors of the students' perception of the third dimension. Physical educators working with students with gross locomotor impairments or low perception of the third dimension need to adjust their teaching and offer opportunities for successful involvement in physical education classes and sports.
