Monocular and Binocular Depth Cues

In this video, we continue our discussion of the human perceptual system by discussing how we perceive depth. Using a variety of examples and demonstrations, we focus specifically on the two types of cues critical for depth perception: monocular depth cues and binocular depth cues.

Monocular Depth Cues: Depth cues that only require one eye to see.

Binocular Depth Cues: Depth cues that require both eyes to see.

Relative Size: The first monocular depth cue, which states that, all else being equal, more distant objects tend to look smaller.

Texture Gradient: The second monocular depth cue, which states that object textures become less apparent farther away.

Interposition: The third monocular depth cue, which states that if Object A blocks our view of Object B, Object A must be closer to us than Object B; also known as “occlusion.”

Linear Perspective: The fourth monocular depth cue, which states that parallel lines converge as distance increases, eventually meeting at a vanishing point.

Height in Plane: The fifth monocular depth cue, which states that distant objects tend to appear higher in our visual planes than closer objects.

Light and Shadow: The sixth and final monocular depth cue, in which objects cast shadows that tell us their 3-dimensional shapes.

Binocular Disparity: The first binocular depth cue; because our two eyes are offset, they produce two different images; our brains use the disparity between these images to calculate depth, with larger disparities meaning closer objects.

Binocular Convergence: The second and final binocular depth cue; looking at closer objects causes our eyes to converge; our brains use this information to calculate depth, with more convergence meaning closer objects.

This is an amazing video! Cleared most of my doubts. Im taking ap psychology exam btw

[naziraa.]

Great explanations with examples. I've been reading an article about depth cues and couldn't catch a thing, now I understand a lot after watching your video.

[anjujeeva]

Am an optometrist from India, Kerala....your explanation is really hepful...Thank you so much sir

[smileliu]

thank you for helping me understand these two concepts so well!! very good examples and simple demonstration for easy understanding! our brain is brilliant!

[senanurkaya]

Excellent video with great explanation. I have an exam today and it is very helpful. Thank youu

[fionaharris]

was utterly lost in a lecture about this but you explained it so well!! thanks a lot!!

[tahreemzahra]

Finally found the best video on YouTube.. ThankYou❤️

[yzkkoch]

At first, when I was reading the keywords for visual cues and constancies on the AQA psychology textbook I was so confused. But now that I watched this I definitely understand way better and I re read the keywords and they make much more sense !! Thank you so much! You explain so simply which makes it easier to understand👏

[aliciagibson]

This was so helpful! I'm studying for the EPPP (psychology licensing) and this really helped provide examples I wasn't understanding from just reading text.

[nihaarsatsangi]

Simply that thumb activity helps you understand it so well!!.
Thanks for the video!....Greatly helpful!

[tehreemfatima]

Excellent video I have ever seen in my life .
God bless u❤️

[armanpreet]

PERFECT! I was struggling so much while studying just couldn’t find an appropriate video that could help me understand the concepts better! This one was very helpful! Thank you ♥️

best teacher with very good explanations

I've actually never had binocular depth perception, all because I'm blind in my right eye. I kept hearing that you need two eyes to perceive depth, so I thought for a while that I didn't have any depth perception. Now I know that I do indeed have depth perception, I just only have monocular cues. The biggest downside for only having one eye, is that I can't experience 3d movies the same way everyone else can. I can only see one image, so it looks like I'm just watching a regular movie. If some genius could invent 3d glasses that are tailored specifically towards people with only monocular vision, basically recreating the 3d image that normal people see with 3d glasses. I believe that this is only possible using technology, so I may actually be able to create those glasses in the future (I'm a programmer).

Your videos are so so helpful.. keep making them, youre doin an amazing thing, , you just made those things so simplfied .. thank you so much

[djkb]

I’ve never really had binocular depth perception (3D movies are surreal to me and nauseating since the glasses force my brain to process binocular vision) but know my brain still understands depth.

This was interesting to learn the actual mechanics for my level of depth perception

[ranjita.sudhish]

Precise explanation. Very helpful. Appreciate your effort. 👏🏻

[ashlinpw]

Thank you so much. Hopefully I do well on my quiz tomorrow now.

Best vedio, made me understood this chapter👍👍👍🏅🏅🏅🏅

Excellent I have never seen this kind of lecture appreciated
