Moors identified validity with establishment of "basic theoretical understanding" of the measures. It is agreed that theoretical understanding has an important role in making measures more valid and useful.…

The Preschool Implicit Association Test (PSIAT) is an adaptation of an established social cognition measure (IAT) for use with preschool children. Two studies with 4-year-olds found that the PSIAT was effective in evaluating (a) attitudes toward commonly liked objects ("flowers"="good") and (b) gender attitudes ("girl"="good" or "boy"="good").
