(c) As indicated above in the introduction to the chapter, correlations can be used to indicate test-retest reliability, or alternate forms reliability. What information about the measures of visualization would be provided, if what we have called the visualization retest score was instead an equivalent form of the test rather than a retest using the same measure? What would be the procedure for measuring visualization and visualization retest scores?
