Matrix reasoning<br />
(23 retained, 7 new)<br />
Designed to tap fluid intelligence, broad visual intelligence, classification and spatial ability,<br />
knowledge <strong>of</strong> part-whole relationships, simultaneous processing, perceptual organisation<br />
Administration<br />
•Examinee views incomplete martix or series and selects response<br />
that completes it<br />
•Essential to point to the visual stimuli, response items and question<br />
mark as stated in manual<br />
•Four types <strong>of</strong> items:<br />
•Pattern completion, classification, analogy, serial reasoning<br />
•Not timed but record NR if no response after 30 secs<br />
Scoring<br />
•0 or 1 for each item<br />

Limitations <strong>of</strong> <strong>WASI</strong>-<strong>II</strong><br />
•Does not provide a comprehensive evaluation <strong>of</strong> an individuals<br />
intellectual functioning<br />
•Does not include subtests from the third and fourth factors <strong>of</strong> the full<br />
batteries – therefore may not provide a good estimate for people<br />
stronger in these areas<br />
