q3 i? Infrequent category alternation produced significantly higher categorization accuracy than frequent alternation. → Goldstone 1996

q3 · i? · causal · r1

Overall accuracy comparison in Experiment 2's categorization task with 26 undergraduates. The authors attribute the advantage to the materials allowing efficient image-like characterizations, since no features perfectly distinguished the categories.

"Categorization accuracy was significantly higher for infrequently altered categories than for frequently al­tered categories [F(1,24) = 8.3, MSe = .09,p < .05]."

Discussion¶

Related Claims¶

• Frequent alternation of categories yields more interrelated concepts than infrequent alternation, as indicated by a diagnosticity-by-alternation interaction — related
• Alternating example-practice pairs produce faster and more accurate near-transfer solutions than blocked presentation of examples followed by practice — reports the opposite
• Inserting trivia questions between interleaved exemplars impairs inductive learning when it disrupts juxtaposition of categories, with total spacing held constant — reports the opposite
• 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
• Imagery instructions yield more isolated concepts than discriminating-feature instructions, as shown by greater influence of nondiagnostic features on categorization accuracy — related
