pense of the vividness and variability of sensory stimuli, but<br />

possibly involves a loss of special perceptual functions other<br />

than those to which we are accustomed. There is evidence to<br />

support this concept.<br />

Werner, in a statement based on studies of eidetic imagery<br />

in children as well as on broader studies of perceptual de-<br />

velopment, states that the image "... gradually changes in<br />

functional character. It becomes essentially subject to the<br />

exigencies of abstract thought. Once the image changes in<br />

function and becomes an instrument in reflective thought,<br />

its structure also changes. It is only through such structural<br />

change that the image can serve as an instrument of abstract<br />

mental activity. This is why, of necessity, the sensuousness<br />

and fullness of detail, color, and vividness of the image must<br />

fade." The experimental work of Kohler illustrates this con-<br />

cept. In reviewing his experiments on the effects of wearing<br />

distorting lenses for days at a time, Kohler concludes, "We<br />

are confronted here with a peculiar relationship between op-<br />

tical and physical facts. We always find that it is the physical<br />

dimensions of things which have a tendency to become vis-<br />

ually correct. This is due to the fact that physical dimensions<br />

are among the most frequent and symmetrically distributed<br />

stimuli. Consequently, it is with these stimulus qualities that<br />

unique perceptual experiences of straightness, right angular-<br />

ity, and good form tend to become associated. It is always the<br />

physically unique stimuli which gradually become the refer-<br />

ence standards for our percepts. This is the reason why in the<br />

process of adaptation it is always the world with which we are<br />

familiar which wins out in the end. It does so in the interest<br />

of simplicity and economy." From another field of inquiry,<br />

Shapiro has summarized evidence for the primacy of color<br />

responses in children, with particular emphasis on Rorschach<br />

data. He writes "... although the Rorschach data did not<br />

indicate that color responsiveness per se diminishes with<br />

development, they do indicate unmistakably that the relative<br />

significance of the color as an essential and overriding aspect<br />

of the percept diminishes." Shapiro concluded, "... color<br />

perception as such is a more immediate and passive experi-<br />

ence than form perception, requiring less in the way of per-<br />

ceptual tools for <strong>org</strong>anizing capacity. It is associated with a
