Information Transmission with Unequally Likely Alternatives

Abstract

Previous investigators have concluded that the linear relation between reaction time (RT) and transmitted information found for equally likely stimuli (ELA) does not hold for unequally likely stimuli (ULA). However, the possibility still exists that a correspondence can be found by the use of a subjective probability measure. Accordingly, nine Ss were run on a choice-RT task under conditions of both ELA and ULA stimuli. The results for the ELA data confirm previous findings. The results for the ULA data not only do not support the experimental hypothesis but are completely at variance with previous results.
