9.35 Illusion Laboratory

For each picture in the illusion review, write a sentence that briefly describes what perceptual principle is being demonstrated and what kinds of perceptual processing and phenomena are involved in the demo design (think in terms of class topics/concepts). Submit a document on LMOD with your answers.

Example for one of the listed illusions (which?): "This illusion relies on combining stereopsis and color perception to show that perceived color relies on perceived depth."

Come up with a idea for making an illusion that answers a new scientific question about perception. This illusion should be inspired by at least one of the papers on the list. Attend a meeting with one of the course staff to discuss the idea(s). It is helpful to have an initial illusion design/sketch to discuss (even if you haven't created the illusion itself).

Sign up for a slot here and if you can't make any of these then email your TAs.

Fill in the html template on the Resources page to design your webpage. Feel free to personalize it as much as you want, as long as it clearly includes:

• A new scientific question that your illusion is meant to address
• An explanation of your illusion design, and how it is meant to address your question
• Your illusion: one or more than one image, gif, or video for others to view
• The citation to the paper(s) that inspired your illusion

Please keep in mind that this webpage is for others to read and understand your illusion: to aid in this, your writing should discuss concepts covered in class. Create a zip folder with all of the necessary components and submit it on LMOD.

You will be assigned two of your classmates' submissions in the gallery. On each, leave a 2-3 sentence comment that covers the following:

• a) Pretend you are a research subject participating in your classmate's experiment. Describe your subjective experience of the illusion.
• b) Now, pretend you are the researcher and assess whether your experience of the demo was helpful in answering the stated question.

Make sure to include your name. Feel free to include comments on other illusions as well!

On your own illusion page, respond to the comments by your classmates. Pretending you are the researcher,

• c) Assess whether the subjective reports answer your question
• d) Identify what changes you could make to your illusion to get a clearer answer to your question; OR, ask a follow-up question based on the answer you've arrived at.

On LMOD, submit a document to tell us at least one way we could improve this assignment. Thanks!
