Episode 31: Lemon Slices and a New Face on Mars! Gestalt Principles at Work

by Michael on October 2, 2007

The gestalt principles of perception – how do they explain how we not only sometimes perceive strange things, but also how we can appreciate works of art? In this episode I take a close look at why people see a lot of strange things around them – including me. We’ll see images on lemon slices, on Mars, and on building tops. Why do we perceive these things?

Resources for this Podcast

  • Perceptual Set Experiment: go here to do the “Man on a horse” experiment I created. You can run this experiment on your friends, or even use it for a project in class. Have fun with it and let me know if you’ve got any feedback/suggestions. NOTE: The control condition is the “condition 1″ button (random pictures which are unrelated to the man on the horse). The experimental condition is the “condition 2″ button (pictures of animals which should help the viewer more easily see the man on the horse).
  • Here are a few sites which further explain some of the Gestalt principles of organization:

  • You can learn how psychological gestalt principles apply to web design at the Web Design for Instruction site
  • And more about psychological gestalt principles from the Spokane Falls Community College Graphic Design website.
  • Here’s the NASA site where you’ll find the “Face On Mars” pictures.
  • Here’s a good site which describes the gestalt principles. It’s from the Interaction Design website.

Here is a slideshow of some of the images used in this episode. Roll over the bottom of the box below to see thumbnails of all the images which you can click on to examine any of the photos in more detail.

Hey I think ur website is great but I think it needs a little proof of credibility, I can see you really know a lot about the subject but i think it would give it more prestige if you could add your name and your study level.

Paula,

Check the “About Michael” link under the “Pages” box at the top left. I put a brief bio there as well as a vita that lists my degrees, occupations, etc. You’ll see that I have a Ph.D. in psychology and I taught psych for 10 years at Marist College. I currently work in the area of instructional design at Pearson Education.

I would like to get lemon slice and gestalt principles video. How can I get and use this in my class to show my students. It does not look like the cd you advertise has this specific thing on CD.
I have an Ipod if that makes a difference at all. Would like to play them this video in class on a laptop onto a whiteboard.

Michael Britt 02.08.09 at 4:51 am

Thanks for your interest in the video. If you send me an email (see “About Michael”) with your address I’ll see if I can put the video on a CD and send it to you.

Fauzia,

You’re going to use the Man on a Horse experiment? Very cool. Yes – let me know how it goes.

Latoya Luckett 06.15.09 at 3:18 pm

I think they where some great ideas that you came up with i will be using one of them myself

Thanks Latoya! Michael

I LOVE THE VIDEO AND ALL THE FUNNY PICTURES THAT I COULDNT MAKE OUT UNTIL YOU TOLD US WHAT THEY WERE

UNEIKA MITCHELL 09.08.09 at 7:45 am

Great slide show…but I couldn’t figure it out. My major is nursing and this is my first time taking psychology, it is very interesting, and a little tricky. I wanted you to know that I watched your video on learning the parts of the brain and it helped me alot. I am a visual person, I always have to draw pictures for test, but your way is the best I’ve ever seen. Thanks

Hi Michael, I just watched your podcast on the brain! awesome! wish we had this idea in college. I’m teaching intro to psych now and would love to show this mneumonic during class. Any ideas of how I would do that? I have great equipment. I usually take a flashdrive to class and use the computer there. let me know what you think.

Michael 09.12.09 at 3:32 am

kkg: send me an email and let’s see what we can do. I think we can find a way to help you get the episode on your flashdrive. – Michael

Michelle 10.05.09 at 5:53 pm

Hello
I have been listening to you since high school and continue to do so during college. You’ve helped a lot with my psychology course!
thanks!

Michael 10.06.09 at 2:31 am

Michelle – whoa, you’re starting to make me feel old! :) Thanks so much for letting me know and I’m glad the podcast is helpful to you. That’s what it’s all about for me. – Michael

Guillermo Black 01.26.10 at 9:26 am

That is very cool!!

Tyrone 01.29.10 at 5:22 pm

I think this is very great never experience anything like this.

Majeska Stewart 01.29.10 at 7:35 pm

It is very strange that you see a face on Mars. I wonder is it a woman or man face.

Mineka Hazley 01.30.10 at 7:56 pm

Hi Michael! I loved the examples in the video. I did have a little difficulty viewing the pictures. Until you showed the pictures in different ways. I never knew about Gesalt Perception, but I feel you’ve helped me to understand it. I feel as though the podcast is very informative as it relates to psychology.

Mineka 01.30.10 at 8:03 pm

I also wanted to say thanks for breaking down Gesalt. Closure, Similarity, and Proximity. Every since I’ve watched the podcast I notice myself paying close attention to things that remind me of Gesalt Perception.

Michael 01.31.10 at 3:43 am

Thanks for all the positive comments. It is amazing how often these Gestalt principles of perception come into play in our daily lives. I was thinking about this the other day when I was looking at someone’s handwritten notes – like a lot of people’s handwriting, there were lots of unclosed letters, yet we can make out the full words because of this idea of closure. Well, glad you’re enjoying the podcast!

Daisy 06.03.10 at 1:58 pm

Hello Michael,
I thought this was a great video and it really got my mind to thinking. Some of the images I didn’t see at first but when you zoomed or gave a close up I saw them. I didn’t realize as humans how much our brains works but you brought it to my attention. LOVED IT!

Gwashayla Durr 06.13.10 at 6:06 pm

Hello Micheal, iTHINK THIS IS A WONDERFUL SITE &IT HELPS EXPLAIN THINGS BETTER.. THING iDONT UNDERSTAND FROM READING THE BOOK THANKS :)

Michael 06.15.10 at 2:39 am

Gwashayla and Daisy: glad to hear that you’re enjoying the site and the podcast. Thanks for the comment!

MARTIN 08.26.10 at 6:37 pm

Rajshkehar 08.28.10 at 1:36 am

Hi Michael,
Can you provide more techniques for memorization and organization of Basic Psychological principles. It will be of great help :)

Michael 08.28.10 at 2:25 am

Rajshkehar: there are quite a few episodes on memorization techniques. Click on the link in the right navigation area called “Search Using Keywords” and then find the word “Mnemonics” and click on it.
