Q1: Müller-Lyer Illusion
Whenever you think about illusions, names of magicians such as Harry
Houdini and David Copperfield probably come to mind. However, in the
visual system, illusions are often evidence of how the perceptual system
“changes” what was actually detected by the sensory system.
Experience teaches us to expect certain
perceptual relationships among stimuli. Illusions often take advantage
of these expectations.
Access the CogLab demonstration “Müller-Lyer” and follow the instructions to complete the demonstration.
Based on the demonstration, respond to the following:
- Describe how difficult this task was in your opinion. How accurate do you think you were in this task?
- Looking at your individual data, explain whether your results support the feelings you had about your performance.
- Describe what your data would look like if you
suppose that the wings of the comparison line were drawn inward instead
of outward in the demonstration. - Describe an everyday situation that could partly explain the Müller-Lyer illusion.
