Significantly, I and others have found that children often tend to handle a medium more on the basis of the general image they hold of it than on the basis of its particular offering or intrinsic attributes. Symbolic forms of representation that are perceived to duplicate reality closely (e.g., pictures) are taken to require no knowledge of authorship and no skill for processing.[12] Television, as a general rule, is perceived to be fun, simple, easy to understand, and generally useless. Comprehending televised content is perceived to require no brains, while failing to comprehend it is a sign of stupidity. On the other hand, print is generally perceived to be highly demanding, and success in comprehending a story in print is regarded as a matter of ability. Failing to comprehend print is expected because it is "tough."
Do these differential perceptions make a difference in learning? Indeed, they do! In line with such perceptions, children do not expend much mental effort on a televised story, even when it is quite poetic and requires effort. Thus they learn far less from it than from an equivalent story in print. The largest and most impressive difference in responses is found in the more intelligent children, who mobilize their capacities to learn from the print story but forgo doing so when it comes to TV.[13]
