lexical decsion task help needed

Hi everyone I know this is probably a really easy thing to do but i am having difficulty with it. i am trying to design a lexical decision task. I have entered all my words, nonwords etc, set up trials and blocks etc. So i now have the bare bones of an experiment. but now i want to alter timings. This is what i would like: a fixation point on screen for 500ms my word/nonword to appear for 100ms a blank screen in which subjects respond fpr 1500ms fixation point again for 500ms I just can't seem to figure out the timings bit of inquisit. Hope someone can help thanks heaps Helen

Helen, If I understand, the following should do the trick ... / stimulustimes = [0 = fixation; 500 = stimulus; 600 = blank] / timeout = 1500 ... Fixation, stimulus, and blank are all separate stimulus elements defined in your script. Fixation is the fixation point, stimulus is the word/nonword, and blank is just a blank text to erase the stimulus. The timeout command indicates that the trial should advance if the subject doesn't respond in 1500 ms. Hope this helps, Sean
