PSYC 225 Lecture 1: Day+1_Psychophysical+methods
Document Summary
Spring 2016: go to this website and do the following experiments. Provide a screenshot or snip of the graph and numerical value of your threshold for each method: method of limits: dot threshold. On the screen there was a red cross in the middle of a gray background, and a dot would appear above the cross and i was asked whether i saw the dot yes or. No. the intensity of the dot varied from high to low. I would be shown the dot that i said no to twice before the intensity began to increase to the highest intensity. By averaging the crossover point in each trial, the threshold can be found: method of constant stimuli: dot threshold. A dot would appear on a grey background above a red cross. The intensity of the dot was not in any particular order.
