frequently refers to the physiological <strong>state</strong> <strong>of</strong> being not able to<br />
respond immediately after some event. The term 'adaptation level'<br />
is used in reference to sensory processes. Expectation or<br />
anticipation refers to a process at higher level. The term<br />
'preparedness' may be used in reference to mental or motor<br />
system. As to our <strong>two</strong>-<strong>state</strong> <strong>model</strong>, it is not important to<br />
determine to which kind <strong>of</strong> processes the term '<strong>state</strong>' refers,<br />
physiological, sensory or conscious ones. These processes may<br />
occur simultaneously. What we should make clear is that there<br />
are <strong>two</strong> <strong>state</strong>s in one <strong>of</strong> which the subject can be at a given<br />
<strong>time</strong>. But, if these <strong>state</strong>s have some names, it would be better.<br />
According to Falmagne(1965)'s terminology, the term 'prepared'<br />
will be used.<br />
As to the type <strong>of</strong> the new <strong>model</strong>, it should be qualitative.<br />
In order to make the <strong>model</strong> quantitative, we must adopt a specific<br />
psychophysical scale <strong>of</strong> <strong>time</strong>, because the anticipation is based<br />
on the perception <strong>of</strong> <strong>time</strong>. But, as reviewed in chapter III,<br />
there is no scale <strong>of</strong> <strong>time</strong> which is accepted by most investigators.
