Despite the explosive growth in stereotype threat (ST) research over the decades, a substantive amount of variability in ST effects still cannot be explained by extant research. While some attribute this unexplained heterogeneity to yet unidentified ST mechanisms, we explored an alternate hypothesis that ST theory is often misspecified in…

Two-phase designs in epidemiological studies of autism prevalence introduce methodological complications that can severely limit the precision of resulting estimates. If the assumptions used to derive the prevalence estimate are invalid or if the uncertainty surrounding these assumptions is not properly accounted for in the statistical inference…

Developmental studies have provided mixed evidence with regard to the question of whether children consider sample size and sample diversity in their inductive generalizations. Results from four experiments with 105 undergraduates, 105 school-age children (M = 7.2 years), and 105 preschoolers (M = 4.9 years) showed that preschoolers made a higher…

Recent research has suggested that young children have relatively well-developed trait concepts. However, this literature overlooks potential age-related differences in children's appreciation of the fundamentally dimensional nature of traits. In Study 1, we presented 4-, 5-, and 7-year-old children and adults with sets of characters and asked…

This article provides an overview of how qualitative research methods (QRMs) can augment the literature in child and adolescent clinical psychology by contributing to theory and hypothesis building. We discuss the utility of qualitative methods in examining the nature of clinical processes and obtaining deeper understandings about quantitative…

Used latent class analysis to test statistically Siegler's rule assessment methodology, the number of rules needed to fit a set of data. Found that rules can be identified, that some are different from those proposed by Siegler, the correct rule is not acquired by subjects, and that the rules in the transitional period are difficult to identify.…
