Hick's Law Research Articles

A further test of Hick's law with unequally like alternatives.

The present study was designed to replicate Lamb and Kaufman's (1965) findings of a relationship between choice reaction time and transmitted information for equally likely (ELA) and unequally likely (ULA) stimulus alternatives. The possible confounding of variability between sessions and between experimental conditions in the Lamb and Kaufman study was eliminated by using a single S in all experimental sessions. Results, in essential agreement with those of the earlier study, suggest strongly that the ELA and ULA conditions are fundamentally different as information sources.
