How not to run an experiment involving participants:

• Let them sit and wait while you finish preparing the computer program.
• Don't make small talk with them or appear at all interested that they are real people outside of your study, and as such, have other things to do.
• Don't tell them about your experiment, what you are studying, how this is interesting, etc.
• Don't give them any directions, just tell them to put on the headphones and follow the instructions on the screen.
• Don't tell them approximately how many questions they will be answering at a stretch, or when they can expect to be done.
• Don't check up on them at all, just let them answer question after question after question after question...
• Keep foisting other tasks upon them, again not giving them warning about how many tasks they'll have to do.
• Make them answer MORE questions, after they've clearly gone through the list already but the computer somehow hasn't stored all the data.
• Make them answer MORE QUESTIONS AGAIN after you and the participant have already agreed on a stopping point.
• Give them a questionnaire at the very end, just when they thought they were finished.
• Ask them to come back next week for another part to the experiment.

Seriously. This is how post-doc research is done? I guess 'PhD' does not equal 'common sense and respect.'
