title: Reinforcer frequency and reinforcer duration as biasers of signal detection.
abstract: Five pigeons were trained to discriminate a constant luminance difference when both reinforcer frequency and reinforcer magnitude were varied in an animal analogue of the human discrete-trial yes- no detection task. Variation of relative reinforcer frequency was more effective in biasing detection performance than variation of relative reinforcer duration. Stimulus discriminability was independent of both reinforcer frequency and reinforcer duration.
