Calculation of signal detection theory measures

Signal detection theory (SDT) is widely accepted by psychologists; the Social Sciences Citation Indexcites over 2,000 references to an influential book by Green and Swets (1966) that describes SDT and its application to psychology Even so, fewer than half of the studies to which SDT is applicable actually make use of the theory (Stanislaw

Sensitivity and Bias - an introduction to Signal Detection

Signal Detection Theory (SDT) offers a framework and method for doing this, and in general for distinguishing between the sensitivity or discriminability (d') of the observer and their response bias or decision criterion (C) in the task

Introduction to Detection Theory

Introduction to Detection Theory (cont ) We wish to make a decision on a signal of interest using noisy measurements Statistical tools enable systematic solutions and optimal design Application areas include: • Communications, • Radar and sonar, • Nondestructive evaluation (NDE) of materials, • Biomedicine, etc

The received signal is usually processed by the electronics to produce at least 2 signals: the strength of one signal is proportional to the R signal strength or magnitude, but is no longer an alternating signal Similarly, the other signal is also not an alternating signal, but rather a signal simply related to X signal strength or magnitude only
