The Relation Between Decision Time and Relative Response Frequency in a Blue‐green Discrimination

Using a two‐choice blue‐green discrimination, decision times were measured for stimuli yielding relative response frequencies of approximately 0.10, 0.50, 0.90 and values close to zero and unity. The results were shown to support the prediction of a so‐called accumulator, or recruitment, model of choice. It is also shown that the results could be well accounted for by assuming that the decisions were based on fixed samples of information which vary in quality.
