Interpretative Considerations• Multiple cognitive processes• Number of processes invoked related
to task difficulty• WISC‐V primary and complementary
measures are specifically designed to measure complex cognitive processes while ancillary measures are designed to measure processes related to learning difficulties.

WMI and PSI
• Involves EFFICIENCY
• Working Memory– Identification, registration, and manipulation of information within STM store
• Processing Speed– Facilitates rapid identification and registration of information for decision‐
making
WMI

Auditory Working Memory
• Digit Span and Letter‐Number Sequencing
• Very similar to WISC‐IV working memory with greater focus on sequencing than previous edition
• Contrast scores:– DSF VS DSB impact of additional
mental manipulation required by DSB
– DSF VS DSS impact of sequencing and number knowledge required by DSS
– DSS VS LNS impact of dual‐tasking and letter knowledge
• Useful when global difficulties with visual processing affecting test performance
Quantitative Reasoning
• New complementary index composed of Figure Weights and Arithmetic
• AR requires actual math problem solving; however, AR is very complex having Fluid Reasoning, Verbal, and Working Memory components
• FW requires math skills in a more limited abstract manner. Requires the ability to reason through a problem and to select the best quantitative operation to obtain the correct response.
General Ability Index (GAI)

I should consider deriving the GAI when‐• a significant and unusual discrepancy exists between the WMI
and MIS or FSIQ.• a significant and unusual discrepancy exists between the PSI
and MIS or FSIQ.• a significant and unusual discrepancy exists between the VCI
and WMI.• a significant and unusual discrepancy exists between the VCI
and PSI.
I should consider deriving the GAI when‐• a significant and unusual discrepancy exists between the VSI
and WMI.• a significant and unusual discrepancy exists between the VSI

and WMI.• a significant and unusual discrepancy exists between the FRI
and PSI.
I should consider deriving the GAI when‐• a significant and unusual discrepancy exists between the WMI
and PSI.• a significant and unusual discrepancy exists between subtests
that contribute to either the WMI or to the PSI.• a significant and unusual discrepancy exists between a
Working Memory or Processing Speed subtest and the MSS‐I or MSS‐F.

Need a Focused ClientBased Approach• Signal to noise ratio
– Adding additional tests can increase signal or can increase noise.
– Adding targeted tests increase signal to noise.
• Consistency of deficit– Need more than 1 score to
identify true weakness in a domain.
• Move away from “shot‐gun” approaches to testing specific hypotheses.– Select tests related to problem.

Case Example
Case Example: Child A
8 year old Caucasian male, 2nd grade– has difficulty sounding out unfamiliar words.– confuses words that appear similar.– recognizes few words ‐ word recognition slow.– dislikes reading circle.– has difficulties with spelling.
