The Money Road Map Test (RMT).

<p>The continuous dotted line represents the path followed by the researcher's pen. Subjects were asked at each successive turn to indicate whether it was right or left. The smaller dotted line in the lower right serves as a practice trial.</p

The two-dimensional (diamond and cross) and three-dimensional (Necker cube, smoking pipe, hidden line elimination cube, pyramid and dissected pyramid) figures copied by the subjects (Panel A). Examples of PG subjects' performance on the Copy Figure Test (Panel B).

Detection and Recognition of an Object Test (DROT).

<p>“High noise” and “low noise” sets were presented separately, with the latter following the former. Subjects were instructed to identify the object embedded in the noise.</p
