A MODEL<br />
When we fixed a set <strong>of</strong> FPs to use, we observe that mean<br />
RTs for the various FPs differ (<strong>of</strong>. the results <strong>of</strong> experiment I).<br />
It seems that the subjeot was prepared to respond for FPs with<br />
about relatively middle length. Having this in mind, the following<br />
three assumptions were proposed.<br />
Assumption 1.<br />
A subjeot is in one <strong>of</strong> <strong>two</strong> <strong>state</strong>s, the<br />
prepared <strong>state</strong> (abbreviated.as Sp) ana the<br />
not-prepared <strong>state</strong> (abbreviated as Snp).<br />
Assumption 2.<br />
When the subjeot is in Sp (or in Snp, resp.),<br />
the distribution funotion <strong>of</strong> reaotion <strong>time</strong> is<br />
Fp(x) (or Fnp(x), resp.).<br />
Assumption 3.<br />
At the start <strong>of</strong> a trial, the subjeot is in Snp.<br />
After some <strong>time</strong> has passed, the subjeot enters into<br />
Spa The distribution funotion <strong>of</strong> the <strong>time</strong> at whioh
