ABSTRACT

More specifically, we intend to point out that apparent inconsistencies between geometrical relationships in the real world and in perception such as that of the horizon moon appearing both larger and nearer than the elevated moon are not at all uncommon. In fact, numerous other examples occur that are no less puzzling. Second, we describe some simple observations that show that departures from a geometrically "correct" relationship between size and distance occur in settings other than the moon at the horizon. Finally, we argue that freed from the notion of a unitary internal representation that mirrors geometrical reality, the paradoxes to which we draw attention can no longer be regarded as such.
