    confuse you Your task is always to pick a piece of paper from the scale that would be the closest match to the square at the center of the checkerboard Once you have a number in mind you can indicate your choice using the slider Moving the slider to the right or the left will increase or decrease the number displayed on the computer monitor behind the cardboard strip When the monitor shows the value you have in mind press the red button on the slider to indicate your final choice After you press the red button on each trial the computer monitor on your left will display the message Got response indicating that your response is recorded When this message disappears from the screen the next trial had begun and there is a new square for you to match If you feel that the center square is darker than all of the papers please respond with Darker than 0 5 Darker than 2 0 if the standard palette is used This option will be displayed by moving the slider all of the way to the left If you feel that the center square is lighter than all of the papers but still looks like a surface please respond with Lighter than 9 5 but still a surface This option will be displayed if you move the slider to the right of where it indicates 9 5 If you feel that the center square is lighter than any piece of paper and does not look like a surface but more like a source of light itself respond with Glowing by moving the slider all the way to the right You may take as long as you like to respond and you may look back and forth between the checkerboard and

    paint as the painted surface on the block Please point to the square in the palette that corresponds to the matching paint Take as long as you want to make your choice but please do not touch the block or the palette After you finish doing this for this block we will do the same thing for one more block After the observer indicates the square mark the square position row column in the answer sheet ask them to close their eyes while you remove the first test block and place test block 2 in the location marked 2 For this position the bottom left corner of the block should fit in the v shaped mark FAMILIARITY Cover up the test palette with the black felt Put the three familiarity blocks on the table Now tell the observer the following Now that you have performed a few matches here are three blocks to examine You can touch them or move them anywhere on the table As you look at any of the blocks you may notice that the amount of light reflected from the block appears to change as you move it or rotate it with respect to the light source On the other hand the block itself isn t changing as you move it the paint on the blocks and therefore the fraction of light they reflect is staying the same I d like you to examine the blocks now and get a sense of how the amount of light reflected to your eye appears to change as you move or rotate each block while realizing at the same time that the reflectance of the block itself is constant Take as long as you like and let me know when you are done Wait until observer indicates he or
