Ps101 - lecture 2 - methods of study. Naturalistic (no interference; observing the natural unfolding; ex jane goodall, people watching) Laboratory (naturalistic observation in a laboratory setting; don"t interfere; ex observing students in a study room from outside the windows) Seeing behaviour in natural setting, spontaneously produced. Ethical issues prevent other methods (ex children under 2 using screens) Have to wait for an event to happen. The one you manipulate (ex study rooms - quiet, loud, colourful(control)) The one that you measure/record (ex success/performance) Eliminates extraneous variables (ex try and make it the same room, time, temperature, etc, to eliminate the variables) Happiness? (ex have a bunch of icons showing different emotions. Have them choose which icons they feel best represent them in that moment. The happier they are, the more positive emotions they will choose. ) Selection bias (bias can occur from experimenter (sample incorrectly), or participants) Response to the manipulation is due to expectations not the manipulation.
