I am building a program in which each screen will feature a single word in its center. The individuals words are part of a larger story, but I am trying to manipulate the speed with which people read. If they only have to read one word at a time in their foveal frame, they read more quickly. In working on this experiment I have come across two limitations:
1) My story is 746 words long, but MediaLab only has 500 lines for programming in a given questionnaire. Is there anyway to expand the length of a questionnaire? Would direct RT be a better program for this task? Does it have a similar limit?
2) How do I set the duration for a given screen's presentation for less than a second. I realize 1 second is written as d1, but what about 150 ms? Can I write d150ms?
