Subclaims¶

q2 i? The intervention group's Cognitive Scale composite scores increased significantly after approximately two months of the programme (Z = -4.32, p < 0.01). → van Eeden 2017

Evidence¶

van Eeden 2017¶

van Eeden, R. & van Vuuren, J., 2017, 'The cognitive processing potential of infants: Exploring the impact of an early childhood development programme', South African Journal of Childhood Education 7(1), a499. https://doi.org/10.4102/sajce.v7i1.499

q2 · i? · causal · r1

Wilcoxon signed-rank matched pairs test on the intervention group (N = 29) comparing cognitive subscale composite scores before and after the programme. The article reports "a significant increase after the intervention (Z = -4.32, p < 0.01)" on the Cognitive Scale; no effect size is printed.

"The results in Table 2 show that there was a significant increase after the intervention (Z = -4.32, p < 0.01)."

Discussion¶

Related Claims¶

• After the intervention, the intervention group scored significantly higher than the control group on the Cognitive Scale, with no between-group differences before the intervention — related
• The Numbers in Nappies programme showed no statistically significant effect on the Language or Motor scales of the BSID (III) — related
• Infants possess two core numerical systems—approximate magnitude representation and precise tracking of small sets—that underpin later mathematical competencies — related
• Social–emotional functioning of intervention infants rose numerically from the high to the very superior range after the programme, which the authors attribute to added parent stimulation — related
