This chapter describes signal detection theory (sdt; Green and swets 1988) that has served as a modeling tool in behavioral ecology and evolutionary ecology for more than 40 years (oaten et al. Web the pale shades of emotion: Signal detection theory (sdt) was originally developed to describe the performance of radars, which must detect signals against a background of noise.
A complete theory of detection is presented, which is capable of treating general types of signals (e.g. The results are easily generalizable to other decision contexts. Many individuals and organizations make predictions of future events or detection and identification of current states.

Web 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 in foggy conditions or during eyewitness identification. Web a number of psychologists have noted some interesting similarities between research in signal detection and operant conditioning. Web the pale shades of emotion: Web signal detection theory (sdt) provides a framework for characterizing decision making in the presence of uncertainty, taking into consideration that the decision depends both on actual objective information and possible subjective biases of.
