Description

The participant was presented with one grid linking symbols to single-digit integers and a second grid containing only the symbols. They were then asked to indicate the numbers attached to each of the symbols in the second grid using the first one as a key.

This test was introduced in 2016 at the Imaging Clinics.

This measure was also performed online in Category 122.

The OQS website includes a working demonstration of the online version of this questionnaire: https://oqsweb.ndph.ox.ac.uk/modetail.cgi?mod_id=16.
