WebPsychophysical experiments seek to measure the limits of perception. While straightforward in humans, in animals they are time consuming. Choosing an appropriate task and interpreting measurements can be challenging. We investigated the localization of high-frequency auditory signals in noise using an “approach-to-target” task in ferrets, how task … WebSignal Detection Theory, or SDT, ...
