Web1. Noise is normally distributed. Presenting a signal on top of that noise, will therefore shift the amount of sensory activity to the right (higher), by an amount equal to that sensory systems sensitivity to that signal. The four outcomes are: Hit: A hit occurs when the observer correctly detects the presence of a signal and responds, “yes.” It is considered a correct response. Miss: A miss occurs when the observer fails to detect the presence of a signal and responds “no” when the signal is actually present.
