What is the common threshold for determining abnormality of a score related to cognitive functioning?
1.5 SD below normative mean
(~5th percentile)
What are the FIVE principles of multivariate base rates
C - CO - NoT - D - CF
- Low scores are COMMON across all test batteries
- The number of low scores… depends on where you set the CUT OFF score
- … and the NUMBER of TESTS administered
- The number of low scores varies by DEMOGRAPHIC characteristics of the examinee
- The number of low scores varies by level of general COGNITIVE FUNCTION
What is meant by a TOPF-estimated FSIQ
This refers to an IQ that is estimated using tests of premorbid function, like irregular word reading
TRUE or FALSE
TOPF methods can reliably be used to estimate pre-morbid scores on both FSIQ and the individual WAIS & WMS indices
FALSE
TOPF is actually not that good at estimating FSIQ with precision, and is even worse for the individual indices
