Web1. Define the following terms in relation to signal detection theory: hit, miss, false alarm, and correct rejection. A hit is when the participant correctly detects the target. A miss is when the target was there, but the participant did not detect it. A false alarm is when the participant reports seeing the target when it was not actually there. A correct rejection is … Webd’. The most commonly used SDT measure of sensitivity is d’ (d prime), which is the standardized difference between the means of the Signal Present and Signal Absent distributions.
