For the past few days, I was doing the pilot study, which include the procedure of experiment, user interface and difficult levels. I also made some changes to the experiment according to the data analysis result. In order to increase the difficulty, I designed another two versions of secondary task -- distinguishing between even and odd number of tones and using flash effect of border instead of playing beeps. The above two versions will be tested within this week, and I think I can use more than one in the final experiment.
