WebThe theory of signal detections provides the best approach to separate the effects of sensitivity from those of response bias. What led to a "yes" or "no" decision as opposed to "what did the subject hear (or not hear)?" A hit occurs when the signal is present and the subject says "yes". A correct rejection occurs when the signal is absent and ... Detection theory or signal detection theory is a means to measure the ability to differentiate between information-bearing patterns ... then a miss (failing to detect the plane) may increase deaths, so a liberal bias is likely. In contrast, crying wolf (a false alarm) too often may make people less likely to respond, … See more Detection theory or signal detection theory is a means to measure the ability to differentiate between information-bearing patterns (called stimulus in living organisms, signal in machines) and random patterns that … See more P(H1 y) > P(H2 y) / MAP testing In the case of making a decision between two hypotheses, H1, absent, and H2, present, in the event of a particular observation, y, a classical approach is to choose H1 when p(H1 y) > p(H2 y) and H2 in the reverse case. … See more • A Description of Signal Detection Theory • An application of SDT to safety • Signal Detection Theory by Garrett Neske, The Wolfram Demonstrations Project • Lecture by Steven Pinker See more Signal detection theory (SDT) is used when psychologists want to measure the way we make decisions under conditions of uncertainty, such as how we would perceive distances … See more Signal Detection Theory has wide application, both in humans and animals.

So in the last video we talked about psychophysics and we talked about these ideas of thresholds. We had the absolute threshold, which was the minimum amount of stimulation that’s needed for us to detect a stimulus, and ... WebSignal detection theory and psychophysics.
