**Signal Detection Theory Tutorial

Every day we have to make decisions about uncertain events like, 'Is that my phone ringing or one on the television?', or, 'Is the person talking to me telling the truth?' In this tutorial, you will learn about the Signal Detection Theory (SDT) model of how people make decisions about uncertain events. This tutorial explains the theory behind signal detection, covers several SDT measures of performance, and introduces Receiver-Operating Characteristics (ROCs). The tutorial is at an introductory level, but also has optional sections appropriate for more advanced students and researchers. The tutorial consists of explanatory text, interactive examples, and a question section suitable for a classroom assignment. The tutorial also contains a Java applet for computing and graphically portraying SDT models. This tutorial is introductory in level and builds upon other tutorials on the WISE Project's web site. The hypothesis testing tutorial is particularly appropriate, and it is also helpful to be comfortable working with z-scores.

Comments I'm not sure if I would use this in class, simply because I don't have room in my schedule to add another topic. But in a class where it fits, it would be a good homework assignment.
