My program chronically freezes after a few trials. A typical run proceeds as follows:
Event 1) Sentence appears, response = hit space bar (96 sentences in stimulus list)
Event 2) Movie file (.avi, ~ 10 MB), followed by a text field, response = enter a number (8 videos in stimulus list)
Event 3) If the number is incorrect, “INCORRECT” appears on the screen (no response)
Event 4) Sentence appears, response = hit N or Y (96 sentences in this stimulus list)
The program contains about 20 blocks, each of which are linked to one trial (1-20), which is linked to the four relevant events (one for each trial; the sentences had to be presented in random order). Each participant sees only one block, but there are 40 text events (192 sentences altogether) and 1 movie file event (with the 8 videos).
The system: Windows XP, Pentium 4, and from what I can remember, decent memory and hard drive space.
At first I thought the movie files were too large. However, I replaced the video files with much smaller versions (~ 300 KB, not experiment quality though), and the program continued to freeze up (but less frequently). Might I have too many events?
Also, after clicking RUN and entering the participant name (etc), it takes 1-5 minutes for the SAVE dialog box to appear.
