Spreadsheet signal detection [PDF]

open access: yesBehavior Research Methods, Instruments, & Computers, 1999
A number of studies in perception, attention, and memory employ signal detection theory (SDT) to assess the accuracy of an observer's detection or discrimination performance. Some of the problems that students have with understanding and using SDT are associated with the calculations needed to obtain SDT parameters and predictions.
