The Shape Stroop, Bear/Dragon, and Tower tasks showed a pronounced drop in average performance from about 25 to 30 months of age, possibly reflecting systematic missingness rather than declining ability¶

Subclaims¶

q3 i? Meta-analytic POM curves showed a pronounced performance drop from about 25 to 30 months on Shape Stroop, Bear/Dragon, and Tower, which the authors speculate may stem from age differences in systematic missingness. → Petersen 2016

Evidence¶

Petersen 2016¶

Petersen, I. T., Hoyniak, C. P., McQuillan, M. E., Bates, J. E., & Staples, A. D. (2016). Measuring the development of inhibitory control: The challenge of heterotypic continuity. Developmental Review, 40, 25-71. https://doi.org/10.1016/j.dr.2016.02.001

q3 · i? · quant-synthesis · r2

Meta-analytic aggregation of POM by age across included studies revealed this unexpected dip for three named tasks. The authors are "hesitant to infer that inhibitory control abilities declined" and speculate that decreasing systematic missingness with age could lower average scores. No effect size is printed.

"Third, unexpectedly, the Shape Stroop, Bear/Dragon, and Tower tasks showed a pronounced drop in performance from about 25 to 30 months of age."

Discussion¶

Related Claims¶

• The meaning of Bear/Dragon task performance changes with age: go and no-go trial performance was inversely correlated at 30 months (r = −.67) but not at 42 months (r = .12) — related
• Performance on inhibitory control measures improves with age, with some tasks reaching performance plateaus beginning around 4 years of age — related
• Behavioral inhibitory control tasks are useful for detecting individual differences over an average span of only 2.49 years, versus 6 years for the CBQ Inhibitory Control subscale — related
