The following main variables are scored:
- Sum of the differences between correct and incorrect YES answers: Measure of learning ability.
- Sum of correct YES answers: Measure of the ability to recognize repeatedly presented items as such.
- Sum of incorrect YES answers: Measure of the ability to identify items that have not previously been presented as new items and to distinguish them from recurring items.
The subsidiary variables enable separate scoring of learning performance for geometric (high-associative) and irregular (low-associative) figures. Dual coding is easier for the geometric, high-associative items than for the low-associative ones, since it can be assumed that high-associative items can be coded verbally as well as pictorially.
