Lab 3 – WorksheetToday we are going to measure the size of your illusion using the method of constantstimuli. In this method, we are going to keep the length of the reference line constant (i.e.,the line on the left will always be 160 pixels). On each trial you will see different lengths ofthe line on the right, and you need to decide whether the line on the right appears longer orshorter than the reference line.1)In the online experiment you viewed 13 different line lengths. Each line length wasviewed 4 times. At the end of the experiment, the computer displayed the mean % ofthe time you said “longer” for each of the line length. Copy those means into thechart below.LineLength (dpi)Mean % of thetime you saidLonger15001550160016501700175018001857519010019575200100205100210100
2)Create a graph to calculate the size of your illusion (you can do this by hand or byusing the excel/google spreadsheets template). Please paste your graph below.
