DMDX logo DMDX and Flamory

Flamory provides the following integration abilities:

  • Create and use window snapshots for DMDX
  • Take and edit DMDX screenshots
  • Automatically copy selected text from DMDX and save it to Flamory history

To automate your day-to-day DMDX tasks, use the Nekton automation platform. Describe your workflow in plain language, and get it automated using AI.

Screenshot editing

Flamory helps you capture and store screenshots from DMDX by pressing a single hotkey. It will be saved to a history, so you can continue doing your tasks without interruptions. Later, you can edit the screenshot: crop, resize, add labels and highlights. After that, you can paste the screenshot into any other document or e-mail message.

Here is how DMDX snapshot can look like. Get Flamory and try this on your computer.

Application info

DMDX is a Win 32-based display system used in psychological laboratories around the world to measure reaction times to visual and auditory stimuli. It was programmed by Jonathan Forster at the University of Arizona.

DMDX uses DirectX. This software gives the Windows programmer better access to the actual hardware, which is essential for accurate timing. It is generally believed that it is virtually impossible in a Windows program to get accurate timing of displays, or accurate measurement of reaction times. This is true for applications that do not make use of DirectX, but not for DMDX.

DMDX comes with a sister program called TimeDX. This program is designed to establish the properties of your machine (graphics resolution, refresh rates, type of sound card, presence of PIO card, etc.), and to record these in the Windows Registry, so that DMDX will know what kind of machine it is running on. Both TimeDX and DMDX have their own Help files.

What hardware do you need?

* Pentium PC (or better, including Celeron, AMD K6). These CPUs come with a motherboard that has a High Performance Timer which is essential for DMDX.

* Plenty of RAM -- 32M at least.

* For dual screen displays, either (a) a video splitter to duplicate the output on two monitors (one for the experimenter, one for the subject), or (b) you can take advantage of the MultiMonitor option in Windows 98/ME (not 95), which permits the programmer to write to multiple screens (DMDX just uses two). In this case you need two graphics cards, rather than a video splitter.

* A fast video card with 4M of on-board memory.

* Sound card (not essential if you are not using audio)

* Input device for the subject's response: PIO12 i/o card, keyboard, mouse, game pad, joystick (just the buttons). These vary in their accuracy of measurement of RTs.

Integration level may vary depending on the application version and other factors. Make sure that user are using recent version of DMDX. Please contact us if you have different integration experience.
