In this five minute
video Dr. Kevin McGrew talks about the WJ4 test that is currently being
published. McGrew says, that one of the goals of the 4th
version was to increase the cognitive complexity of the tests. One of the ways to do that is by increasing
the working memory demands of tests. The test developers created tasks that
require the performance of many simple tasks all at once. These kinds of tasks increase working memory
demands. That's what caused Auditory
ability to have the highest g loading in the WJ4. McGrew also tells about his and his colleagues'
efforts to strive to improve the CHC model which is supposed to be an evolving
model.
The video is nice,
but those who want to delve deeper should watch this presentation in which
McGrew presents the WJ4 changes elaborately.
