Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i3 Accuracy on the symbolic comparison task decreased as the ratio between symbols approached 1, with ratio predicting trial-level accuracy. → Amy Bennett 2018

q3 · i3 · causal · r3
A by-items linear regression in Experiment 1 predicted the proportion of participants answering each trial correctly from the trial's ratio, showing "a significant effect of ratio, β = -.744". Overall accuracy also correlated with arithmetic fluency, r = .391.
"This revealed a significant effect of ratio, β = -.744, p < .001, R2 = .554. Overall accuracy was correlated with performance on the Woodcock Johnson arithmetic fluency test, r = .391, p = .001"
Discussion¶
Learner Variables¶
- Number Sense — outcome: instruction changes it
Related Claims¶
- Accuracy on approximate addition decreases as ratio approaches 1, with a stronger ratio effect on the non-symbolic task — related
- Characteristic distance effects occur in both nonsymbolic and symbolic single-digit approximate addition — related
- Preschoolers' ANS task performance follows Weber's Law: accuracy decreases as numerical ratio approaches equality, and improves with age over six months — a broader claim this one bears on
