Scales for measuring subjective distance in children and adults in a large open field.
Five age levels (6, 8, 10, 12 years, and adults, N = 127) estimated distance in a large open field by the fractionation method. Scales for subjective distance were derived for each group. It was found that (a) the adults differed from all the other groups, (b) the 12-year-olds differed from the six-year-olds, (c) all the exponents were smaller than 1, (d) perceived distance in a large open field was characterized by underconstancy, and (e) underconstancy was greater for the younger subjects.
