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)¶

Subclaims¶

q2 i3 In the authors' longitudinal Bird/Alligator variant data, no-go inhibition had a different meaning at 30 months than at later ages, with go/no-go correlations shifting from r[137] = −.67 at 30 months to r[127] = .12 at 42 months. → Petersen 2016

q2 · i3 · quant-synthesis · r2

Anecdotal observational analysis of the authors' own longitudinal testing on a Bird/Alligator variant of Bear/Dragon; correlations at 36 months (r[133] = −.22) and 42 months (r[127] = .12) differed significantly (Fisher r-to-z, p < .001). The printed r = −.67 indicates a large inverse association at 30 months.

"children at 30 months of age who inhibited responses on the no-go trials also tended to inhibit on the go trials (i.e., performance on go and no-go trials was inversely correlated: r[137] = −.67)."

Related Claims¶

• 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 — related
• Performance on inhibitory control measures improves with age, with some tasks reaching performance plateaus beginning around 4 years of age — related
