Open in new tab →Brown & Lenneberg (1954)
Start experiment →A classroom replication of the classic codability-and-memory study: name 12 colours, then try to recognise a subset of them after a 30-second delay filled with arithmetic. Your anonymous results are compiled for in-class discussion.
Heider — Focal Colours (1972)
Start experiment →Rosch Heider's challenge to Brown & Lenneberg. Pick best examples of basic colour names, name 12 chips from three categories (focal, internominal, boundary), then try to recognise a subset from an 80-chip array. The data speak to whether codability drives memory — or whether some colours are simply more distinctive than others.
Gilbert, Krull & Malone (1990)
Start experiment →A classroom replication of Study 1 from “Unbelieving the Unbelievable.” Learn an invented Hopi vocabulary, get occasionally interrupted by a tone, then sit the identification test. The diagnostic asymmetry — false propositions misidentified as true under interruption — is what Spinoza predicts and Descartes does not. (Drawn from the Speech Attacks readings.)
Measuring Conceptual Inflation
Start experiment →A classroom replication of Hansen & Liao's Study 1 on the meaning of ‘racist’. Rate the extension and intensity of ‘racist’, its degree-modified forms, related alternative vocabulary, and a set of thin moral terms — then compare your live audience's pattern with the published representative-sample results.
