Two metrics adding up to PROCESSING SPEED. Usually they match. Not me:
a) Symbol Search 95% Percentile
b) Coding 1% Percentile.
PROCESSING SPEED SUBTESTS
The client, under time pressure, scans a search group and indicates whether one of the symbols in the target group
matches. This test measures:
■ processing speed
■ working memory with visual stimuli
In this subtest individuals are asked to record associations between different symbols and numbers within time limits. This
■ psychomotor speed
■ ability to absorb new material
■ visual motor speed
■ drive for achievement
Another description for Coding is fine motor skill, short term memory and learning ability. Strange combination there.
