Cognitive Processing Clusters from the Woodcock-Johnson Psycho-Educational Battery, III:
1. Auditory processing: discrimination, comprehension & synthesis of sounds & patterns, closure, figure-ground, auditory attention
2. Short-term auditory memory: apprehension & immediate use of information gained through the auditory channel
3. Visual processing: perceiving, analyzing, and thinking with visual patterns, spatial configurations, designs, spatial orientation; visual recognition & memory
4. Processing speed: ability to perform relatively automatic cognitive tasks quickly or under the pressure of timed conditions
5. Comprehension-knowledge (or language): breadth & depth of background/cultural knowledge & experience; comprehension of communication & the types of reasoning based upon previously learned procedures, or "crystallized intelligence"; vocabulary, word retrieval
6. Fluid reasoning: capability to reason with qualitative information; conceptualization; rule formation, mathematical logic; drawing inferences from relationships and comprehending implications; creative & abstract problem solving; transfer; transformation & extension
7. Long-term retrieval: storage of information & fluency of retrieval through association later
Three more clusters combining specific tests above include Verbal Ability, Thinking Ability, and Cognitive Efficiency
Another test of intelligence is the Wechsler Adult Intelligence Scale, III . Besides an overall score, Full Scale IQ, it provides information on Verbal and Performance abilities.
Verbal: Included in the Verbal score is verbal comprehension, the ability to use verbal skills in reasoning and solving problems, and the capacity to learn verbal material. Clusters: Verbal I.Q. and Verbal Comprehension.
Performance: The Performance score reflects the efficiency and integrity of perceptual organization, including nonverbal reasoning skills, the ability to employ visual images in thinking, and the ability to process visual material. Clusters: Performance I.Q. and Perceptual Organization.
Freedom from Distractibility: A measure of attention span, ability to sustain concentration, auditory and visual recall, visual motor integration, numerical reasoning, anxiety under time constraints.
(Note on ADD/ADHD: A low score on the Freedom from Distractibility cluster may be indicative of Attention Deficit Disorder, and is just one of the factors considered in a clinical interview process by a psychiatrist, neurologist, or psychologist. DSPS does not test for ADD or ADHD, but serves those with verified disabilities.)
