Dear Madam/Sir, I am now using Medialab to conduct an experiment and meet a problem. In the experiment, the subjects should be presented 10 different anagrams and those different anagrams should appear individually (that is to say, in ten different pages). I need to record the total response time of subjects to those 10 anagrams and limit the total response time into 15 minutes (that is to say, after 15 minutes the Medialab should present the next section of stimuli automatically). How could I make this? Thanks, Snow
