Where can I find experimental data supportive of the Hick-Hyman law? The Hick-Hyman law states that in a reaction-time experiment, the average reaction time of a human subject is a linear function of the average information $\sum -p \log p$, i.e. the entropy, contained in the stimulus. [Hyman 1953]

Where can I get data supporting this? Data from Hyman’s paper would be great!

EDIT: more precisely, I'm looking for a complete, trial-by-trial dataset; not just averages.
In Hyman (1953) the following data is shown (Fig.1). The bits of information were the number of choices in an AFC task, where 1 to 8 alternatives corresponded to 0, 1, 1.58, 2.00, 2.32, 2.58, 2.81, and 3 bits of information (the 2log of the N alternatives).
