LOCAN: A general FORTRAN program for latency-operating characteristic (LOC) analysis

Abstract

A FORTRAN program to compute latency-operating characteristics (LOCs) is presented. Latency and accuracy scores from within-subject designs having equal cell frequencies and containing no missing data are appropriate. Output includes both latency measures (mean and median reaction times) and accuracy measures (d', d 12 • log odds. and log eta) for each latency band. The user determines the number of latency levels into which the data are partitioned. Input, output, and program subroutines are discussed.
