“…So the first theoretical argument is that a mapping-like activity, playing with miniature landscapes consisting of toy-signs and seen from above, is crucial in macroenvironmental learning and explains, in an immediate sense, the precocious ability of 3-5-year-old children to read air photos and solve mapping problems presented in toy and air-photo form. That the pattern emerges at ages well below three (3:0) seems confirmed (if only weakly) on several grounds: first, the fact that it is well-developed at the age of 3 (Blaut and Stea, 1974), manifesting itself at that age in macroenvironmental toy-play behaviour which a child cannot fully verbalize and which appears not to improve significantly in the fourth and fifth years, is suggestive of a long prior development; secondly, informal supportive evidence was obtained in observation of a few 2-year-olds; and thirdly, considerable research on toy play by other investigators, with other research problems in mind, provides supporting evidence because much of the toy-play observed in these studie was, indeed, modelling of places (Erikson, 1937;Lowenfeld, 1938).…”
