Factor analysis of correlations among the measures of recall clustering, free sorting, and recognition errors revealed significant convergent validity for consistent use of a semantic perceptual organization strategy in the three tasks. Ten-year-old, adult, and elderly adult subjects relied on a semantic strategy; four- and six-year-olds encoded…

English-speaking and Dutch-speaking children were asked to pick the big, tall, or long members of pairs of bricks. Comprehension improved with age but older children in both groups were prone to choose the taller (but smaller) of two objects when asked to point to the bigger one. (SED)
