Install the Wineskin Winery application.If you want to skip ahead, you should be able to download my pre-built Wineskin bundle and run DMDX from it directly without any further configuration. Wineskin bundles up each app into its own isolated environment. We will setup DMDX through the incredibly useful Wineskin project, which is a suite of tools built around an open-source tool originally meant to allow Windows-based programs to run on Linux. If you have wanted to run DMDX on your Mac, follow these steps and you should be ready to go! My wife was simply told that it won’t run on Macs, that if she wanted to do that she would have to install Windows on her Mac computer. My primary goal here today is limited to installing and running DMDX on OS X, presumably to run on a MacBook-family laptop. Mainly, DMDX is so difficult to work with that there a small crowd saturated with institutional knowledge about the product which unfortunately won’t translate into other systems. Because its source code isn’t available I can’t make any comments on the quality of its internal programming, but the user-facing side of this project is riddled with quirky traditions and clumsy design. Why is there a whole blog post about this?ĭMDX is archaic. Amanda is using it currently to understand the relationship between image quality in textbooks and learner comprehension. For example, one could perform a study to determine how lack of sleep impacts our ability to think by timing how long it takes for someone to answer whether a given word on the screen is a US state or not. If you are unfamiliar with DMDX (which you probably are unless you searched specifically for it and came to this post), it’s a very old and proprietary piece of software designed to record a test-taker’s response time to preprogrammed stimuli. In this post, I am publishing instructions on how to install a piece of software, called DMDX, on a Macintosh computer with the hopes of making it easier for researchers like her to take advantage of this tool without further adding to its already long list of hassles. Many of you know that my wife spends a good deal of her time studying the ways in which immigrant, refugee, and minority language learners acquire a new language differently than for those who grow up learning it in school.
