Document Summary

----------- = the right line (the comparison line) ----------- = the left line (the reference line) The left line doesn"t change in length, thus it is the control experiment. It will remain at a constant 140 pixels long. The right line"s length will vary from short to large. The probability of saying the line on the right is larger than the left is the dependent. It will be higher because when the comparison line is close to the reference line, your time increases. Method of constant stimuli: such as being given constant sounds or constant lines. It"s presenting you with several stimuli and your job is to say whether you can detect the stimulus or not. The signal detection can be a hit and miss. Signal detection theory is used in advertisements; you may not experience it consciously. Ex: jumping in a pool and it"s really cold, but after 20 minutes, your body adapts to the temperature.
