The interpretation of retest scores is problematic because they are potentially affected by measurement and predictive bias, which impact construct validity, and because their size differs as a function of various factors. This paper investigates the construct stability of scores on a figural matrices test and models retest effects at the level of…

A framework is proposed to explain the results based on a combination of approaches to explain dissociations found in memory. (SLD)
