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 i? The numerical comparison group subsequently performed more accurately on symbolic arithmetic problems than the line-length addition group (t (46) = −2.576, p < .05). → Hyde 2014

Evidence

Hyde 2014

Hyde, D. C., Khanum, S., & Spelke, E. S. (2014). Brief non-symbolic, approximate number practice enhances subsequent exact symbolic arithmetic in children. Cognition, 131(1), 92-107. https://doi.org/10.1016/j.cognition.2013.12.007

q3 · i? · causal · r2

In Experiment 1's accuracy analysis of the symbolic arithmetic test, the main effect of Training Condition was only marginally significant (F (3,92) = 2.598, p = .057); "the only pair of groups showing a difference in accuracy was the line-length addition group and the numerical comparison group pair".

"post hoc pairwise comparisons revealed that the only pair of groups showing a difference in accuracy was the line-length addition group and the numerical comparison group pair, with the numerical comparison group subsequently performing more accurately on the symbolic arithmetic problems (t (46) = −2.576, p < .05)"
