== **DMDX** == 

**Description:** 

DMDX is a free software for experimental control and timing of stimulus display. It is created in the Department of Psychology at the University of Arizona by Jonathan and Ken Forster. The first step about this software is made on May 5 1997. At the begin DMDX was separated in two parts DMTG and DM respectively DMDX is DMTG and DM successor. Also we can tell that DMDX has many updates. DMDX works on Windows operating systems expect Windows 8 and Windows 10, it is waiting for updates. DMDX needs to be set up properly, using associated program TIMEDX and each configuration will be specific to each computer. 
DMDX is a program that can be used to run psychological experiments, to presents lists of stimuli (pictures, text, sounds) that are prepared and specified by you, to collects responses, for example: "Which keys are pressed on the keyboard and how long did it take before they were pressed" and also DMDX saves the RT and correct/error responses in a data file for later analysis.
