You might consider giving your participants a few practice trials, to familiarize them with the procedure.
The web site for the Dmmdx 9 version of Psyscope appears to have been scaled back recently, but there’s still a link to the manual, which is useful see below.
Sample scripts, including a script for semantic priming, can be found on the DMDX web site. Experiments can only be designed using a scripting language. Then you will want to run some basic tests to make sure that everything is properlycalibrated.
Download this file, and then run the installer.
These can be found in the folder “Presentation Labs”. You will only need to consult a few sections of the manual, from the earlier chapters.

The following three programs prepare data for analysis: Psyscope X is in an almost continuous state of development. You will only need to read a small portion of the manual. Based on your first frequency sensitivity experiment, it should be relatively easy to create a the second semantic priming experiment.
If this does not happen automatically, you should look for the Stuffit Expander program Macintosh: Remember to redo this last step if you change the video mode in TimeDX. If you have tutorlal experimental control package that you like to use in your tutlrial, then you should feel free to use this Ask your classmates to participate — and offer yourself as a participant in their tutotial

Presents stimuli and records responses. You should aim to test at least participants in your experiments. Learning Psyscope In order to create your experiment, you will need to learn some basic features of Psyscope. Normally, you would want to include only native speakers, of course, but for the purposes of this lab exercise, advanced non-native speakers will also suffice. In writing-up the results of your studies, you should explain your choice of methods and stimuli.
The setion on running trials may be quite useful to you at an early stage. You might also want to have somebody else take a look at the experiment for you, to see if they have any suggestions on whether the experiment is easy to run or not.
Feel free to ask for help when you need it. Use file transparent file names so that you remember which file is for what djdx. Click ‘Start’ to run the test for a short tutoriial say, seconds.
