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? Image-instruction subjects drew significantly more nondiagnostic features correctly than discriminate-instruction subjects. → Goldstone 1996

Goldstone 1996¶
Goldstone, R. L. (1996). Isolated and interrelated concepts. Memory & Cognition, 24 (5), 608-628. https://doi.org/10.3758/bf03201087
q3 · i? · causal · r1
Post-task drawing measure in Experiment 1: after categorization, subjects drew their concepts on empty 3 x 3 grids. The overall feature-drawing difference between groups was only marginal [t(26) = 1.94, p = .06], but the nondiagnostic-feature difference was significant.
"Importantly, the difference was particularly large for non diagnostic features (image = 8.2 out of 11 correct segments, discriminate = 6.7 correct) [t(26) = 2.25, p < .05]."
Discussion¶
Related Claims¶
- Imagery instructions yield more isolated concepts than discriminating-feature instructions, as shown by greater influence of nondiagnostic features on categorization accuracy — related
- Concepts become more interrelated with practice under discriminate instructions, and more isolated with practice under image instructions — related
- Whether a prototype or caricature is categorized more easily is predicted to depend on concept interrelatedness: prototype advantage for isolated, caricature advantage for interrelated concepts — related
