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.

q2 i1 In Experiment 1, the Confirmatory-Only condition rated nuclei marginally more important than the Complete condition after learning, ηp2 = .011. → Ramsburg 2015 q2 i? In Experiment 2, participants rated nuclei and ribosomes as more important than any other attribute regardless of condition. → Ramsburg 2015 (2)

Evidence

Ramsburg 2015

Ramsburg, J. T., & Ohlsson, S. (2015). Category Change in the Absence of Cognitive Conflict. https://www.google.com/search?q=%22Category+Change+in+the+Absence+of+Cognitive+Conflict%22

q2 · i1 · causal · r?

Post-task two-way ANOVA of 7-point feature-importance ratings in Experiment 1 (21 participants' ratings lost to a programming error). The misconception feature nuclei was rated marginally more important by the Confirmatory-Only condition, indicating the initial conception persisted after target learning.

"The Confirmation-Only condition rated nuclei as being marginally more important compared to the Complete condition, F(1, 306) = 3.43 p = .065, ηp2 = .011."

q2 · i? · causal · r2

In Experiment 2's post-task ratings ANOVA there was no condition main effect and no condition × attribute interaction; participants rated both the misconception feature (nuclei) and the target feature (ribosomes) as most important, consistent with both conceptions remaining in memory.

"Pairwise comparisons for attribute type revealed that regardless of condition participants rated nuclei and ribosomes as more important than any other attribute, p's < .001."
