Abstract: | The threshold of a brief signal temporally centered in a noise masker first increases and then decreases as the masker is increased in duration. We discuss two explanations for this “over-shoot” phenomenon which consider the role of peaks of an exponentially weighted sliding integrator. One such explanation takes into account the finding that the steepness of the psychometric function continues to increase monotonically as its location moves first right and then left. |
