Subclaims¶

q3 i? The Session x Jump Category interaction was significant: children who jumped from subset-knower to CP-knower showed the biggest change in w (Δw = -0.455) versus CP-Non-Mapper-to-Mapper (Δw = -0.069) and Subset-to-Subset (Δw = 0.001). → Shusterman Anna 2016 q3 i? The same pattern held with percent correct: the S2-to-S5 Session x Jump Category interaction was significant and subset-to-CP children showed the largest gain (M = 6.11%). → Shusterman Anna 2016 (2)

Evidence¶

Shusterman Anna 2016¶

q3 · i? · associational · r2

Repeated measures ANOVA on 27 isolated knower-level jumps, comparing w at [t-1] and [t0] sessions by Jump Category. Post-hoc: only Subset-to-CP vs Non-Mapper-to-Mapper reached significance (p = .02); Subset-to-CP vs Subset-to-Subset did not (p = .19).

"The Session x Jump Category interaction effect was significant, F(2,16) = 4.66, p = .03 (n = 19), indicating that different advances in children's verbal number knowledge were differentially related to changes in ANS acuity."

q3 · i? · associational · r2

ANCOVA with S2-to-S5 percent correct, age and sex as covariates, replicated with w (F(1,29) = 3.89, p = .05): Subset-to-CP (M = 6.11%) exceeded Subset-to-Subset (M = 3.54%), Non-Mapper-to-Mapper (M = 4.44%), and No Change (M = 2.17%) groups, p < .05 for the first three comparisons.

"A parallel analysis using S2 and S5 percent correct scores as the repeated measure similarly showed a significant interaction of Session and Jump Category, F(1,33) = 10.69. p < .01 with post-hoc Tukey's HSD again indicating that the subset-to-CP-knower group exhibited the largest gain in percent correct"

Discussion¶

Related Claims¶

• The Who Has More task showed moderate test-retest reliability (r = .46) in preschoolers, and the authors call for more stable ANS measures for this age — related
• Children's knower level of verbal number words is cross-sectionally associated with ANS acuity even after controlling for age and sex — related
• Knower levels were longitudinally stable across sessions, replicating Wynn, while the CP-Non-Mapper/CP-Mapper distinction fluctuated across sessions — related
• ANS acuity (w) did not significantly improve within children over the six-month period in the session-level analysis, though a hierarchical linear model detected a linear increase in percent correct — related
