Processing Speed Index (PSI)

Measures the speed of information processing with visual material, involving visual identification, decision making, and decision implementation.

Quantitative Reasoning Index (QRI)

Measures reasoning with numeric information.

Auditory Working Memory Index (AWMI)

Measures auditory attention and concentration.

Nonverbal Index (NVI)

Measures general nonverbal intellectual ability.

General Ability Index (GAI)

Measures general intellectual ability excluding the effects of attention/concentration and information processing speed.

Cognitive Proficiency Index (CPI)

Measures efficiency in cognitive processing.

Naming Speed Index (NSI)

Measures automaticity of basic naming ability involving visual-verbal association and verbal retrieval.

Symbol Translation Index (STI)

Measures visual-verbal associative memory involving recognition memory.

Storage and Retrieval Index (SRI)
