Note on development of perception of size.
The development of the perception of size is currently interpreted as the development of size constancy. Using data from prior studies, this paper reports a functional measurement analysis of the perceived size of rectangles located on a frontal plane. Analysis shows the development of the perception of size may depend on what can be called the development of size isomorphism. While size constancy may change during childhood with the ability to use cues of size and distance, it is proposed that the extent of size isomorphism may change with age given change with age in the neural representation of perceived length and in the working parameters of the neural mechanism which generates perceived length. Current interpretations of changes with age in the perception of size may confuse changes in perceived size given development of size constancy with changes in perceived size based on development of size isomorphism.
