Inverted T Experiment Essay

The experiment started out with an inverted T in which the vertical line was changing in length.
The object was to click on the moving vertical line when you considered the parallel and vertical lines of the T to be the same length, this would stop the vertical line from moving. When you considered the two lines to be the same length you would click the “show results” button and the application would analyze your percentage of how similar the two lines were in size and change in color to reference the two lines more efficiently.

I conducted this experiment a total of four times before I successfully completed the activity. The first time scoring 105%, the second time 91%, the third attempt 96% and the final time 100%. I think the reason I had trouble reaching the 100% goal was because the first time the vertical line being 5% off I over compensated resulting in the second attempt scoring 91% of the two lines matching. Additionally, with the still line being parallel and the moving line being vertical it is difficult identifying at which point the lines are identical, I wonder if the lines were switched with the moving line being parallel and the still line being vertical if the experiment would have had the same results.
Vicario referenced three perceptual measurements Protagoras’ illusion, Kant’s Formalization, and Mach’s inverted T illusion. In Vicario’s conclusion he disagreed with fisher’s methods and concludes his argument has to be
