WJ III cognitive test deficits--base rates of number of deficient tests

Kudos to Scott Decker, Joel Schneider and Brad Hale for the excellent article on how to estimate base rates for the number of deficient test scores (using various levels of standard score deficit criteria (e.g., SS <= 80; SS <=70) in the Woodcock-Johnson III (WJ III) Standard and Extended cognitive batteries (tests 1-14). Not surprisingly, they find that the number of relative weaknesses a person displays is most likely more than most clinicians would believe.

Of more practical significance is a series of smoothed figures they provide, by age, which would allow clinicians to determine the base rate significance of number of deviant WJ III cognitive tests (from primary 14 tests).

How to estimate best IQ score if someone has taken multiple IQ tests: The psychometric magic of Dr. Joel Schneider

Dr. Joel Schneider has posted an excellent explanation on how to estimate a person's "true IQ score" when a person has taken multiple IQ tests at different times. Probably the most important take-away message is one should never calculated the simple arithmetic average. The median would be more appropriate, but Joel provides and even more psychometrically sound method and an Excel spreadhsheet for implementing his excellent logic and methods.

Neural efficiency and general intelligence: Is it mental quickness or timing?




Today I made a post at IM-HOME discussing the neural efficiency = general intelligence hypothesis (Arthur Jensen) where I make the case that recent research suggests that temporal or timing g (the internal brain clock) is a more fundamental cause of neural efficiency than the dominant Jensen reaction time g hypothesis. Check it out.
