greater depth. The unknowledgeable person (the immature neural network) has accumulated<br />

from the statement a crude <strong>and</strong> inaccurate knowledge, which, if it is to be useful, must be greatly<br />

refined by future knowledge.<br />

"Our decreasing ability to accept new things is essential in the making of sophisticated<br />

taste"; if attitude remains too flexible <strong>and</strong> new knowledge is not measured against previously<br />

held knowledge <strong>and</strong> beliefs, "we can only perceive things crudely." (Mok, para. 2). That is the<br />

insight the study of neural networks gives to the theory of learning.<br />

Why different models of attitude change may apply to different areas of attitude. The neural<br />

network model of learning also suggests why the different hypotheses of attitude change may<br />

apply to different areas of attitude. In areas in which a high degree of refinement in learning is<br />

desirable, the impressionable years model or the aging stability model would apply. The<br />

decreasing variability of preference over the lifespan allows highly refined learning to develop.<br />

In areas in which quick adaptability to changing situation is necessary over the entire lifespan,<br />

<strong>and</strong> in which this quick adaptability is more important than refined <strong>and</strong> detailed knowledge, the<br />

lifelong openness model would apply.<br />

In music <strong>and</strong> most other arts, detailed knowledge <strong>and</strong> refined taste are highly valued in most<br />

cultures. On the other h<strong>and</strong>, there are few survival situations in which quick adaptability in<br />

artistic tastes would be crucial. Thus, musical taste tends to follow the impressionable years<br />

model or aging stability model.<br />

A contrasting area of attitude is that of political policies. Markus (1986) found in studying<br />

opinions of policies over a nine-year time period that subjects' opinions of policies often<br />

changed, yet the subjects most often did not believe that they had changed their opinions.<br />

Subjects simply altered their recollections of previous opinions to match current opinions. Here
