Designing the Experiment

Different questions provoke different experimental designs.
  • Have some people set up appointments. Count how many keep them.

    Are subjects using their own preferred appointment-keeping mechanism, or does the experimenter tell them how to set up the appointment?

  • Show some pictures with a subliminal cue, and some without, and count how many are correctly recognized.

    Which pictures are shown in which condition?
