DEVAT : Design of Experiments for Visual Attention Tasks

We describe here a program for the Design of Experiments for Visual Attention Tasks (DEVAT). This program incorporates an extended version of the Eriksen response-competition paradigm. It allows the operator to make experiments with visual stimuli where a target letter is presented surrounded by noise letters in two-dimensional configurations. Reaction times and error rates are measured and then compared with the predictions made by such one- or two-dimensional visual attention theories as the CTVA and CTVA-2D models. The program is written in C++ and runs in the DOS operating system on IBM-PC compatibles with a 486 or later processor. An example with some results provided by DEVAT is given and a demo running in WINDOWS is also included. unknown publishedVersion
