It does provide some information about the depth, but it's not the main source. The main source of depth comes from the image disparity (the difference of images) from the two eyes.

Actually you are supposed to look at the cross and the circle will fall into the blindspot. But the other way around also works.
-
Actually both.

@ChristopherReynolds Sorry for the late reply as I haven't logged on here for a while. My email is shihyulo@nycu.edu.tw

I think so. Poor kitty....

Shih-Yu Lo replied to Jill Hind
You raised a very interesting question. If you use "neural plasticity" as the keyword, you'll find a large amount of studies showing how adaptive our brain is.

@MichaelBland From a psychoanalytic perspective, your ex-president must have played an important role in your life, or your trauma.

I have to admit that it took me quite a long time to see the dog when I saw it for the first time. But afterward it becomes hard for me to "unsee" it.

@DeirdreMacintyre Thanks for sharing this. I Googled it and have found the little cute things you mentioned.

Shih-Yu Lo replied to Jill Hind
Haha, sorry for the mispronunciation.

Shih-Yu Lo replied to Paul Gibbs
Sorry for the mispronunciation. Actually I could't find a good word for it so consulted Google. But still mispronounced it when recording the video.
Anyway, I do agree with you that this example doesn't work 100% of the times. When I showed this in class, some people couldn't see what I wanted them to see. I think individual differences do play an important...

Actually there are quite a lot of studies showing that our memories for crime scenes can be subject to sociocultural factors like stereotypes.

This game sounds really interesting! I should try it with my students next time.

@ChristopherReynolds Thanks for sharing your stories, really incredible. Yes I would love to read your poster/paper.

Shih-Yu Lo replied to Harry Cather
Sorry I think the relationship between lateral inhibition and the receptive field wasn't explained clear enough in the video. But imagine the following scenario:
neuron A
neuron B --> neuron D
neuron CLet's say neurons A and C send lateral inhibitions to neuron B, and neuron B sends excitatory information to neuron D. This would lead to a...

It's not a feature of cones or rods. It occurs on the layer after cones/rods, which is the bipolar cells: https://www.nature.com/articles/nn1298_714

Shih-Yu Lo replied to Paul Gibbs
The "why" question is tricky. The easiest explanation is that it's a product of evolution and natural selection. But who knows?

Shih-Yu Lo replied to John Cullen
Thanks for your comment.
The visual signal transduction is: cones/rods (eye) -> bipolar (eye) -> ganglion cells (eye)-> LGN cells (brain) -> cerebral cortex (brain)
According the paper below, lateral inhibition can be seen as early as the bipolar cell: https://www.nature.com/articles/nn1298_714
But actually I think where it occurs doesn't matter. What...

Thanks for pointing our the typo. We'll try to fix it ASAP.

Thanks for your question. No, normally it's not part of eye tests.

I am sorry that this video is indeed a bit overly complicated. For those who don't really make sense of what I was trying to talk about in the video, here is a Youtube video: https://www.youtube.com/watch?v=zjTCbL2wbRk
-
Sorry to hear about your condition. Did you mean that you lost your sight in the left eye suddenly without any external cause?
-
Shih-Yu Lo replied to Ken Evans
Thanks for sharing your knowledge. Actually I didn't know that owls have higher numbers of rods. But it makes sense as that helps them navigate in the dark.
-
I am sorry that your double vision doesn't apply to your bank account.
-
I think I know how you feel. The inner universe within ourselves is actually the most strange thing to us.
-
I love reading his books, too. Recently I read his autobiography. He had a fascinating life.
-
You actually raise some issues that also fascinate psychologists, neuroscientists and philosophers.
-
I have to admit that this is my first time hearing about your condition. I just did some quick research; the term "aphantasia" was recently coined 2015.
Would you mind talking a bit more about yourself? So, if you try to recall a previous event, like, what you had for dinner yesterday. How would you recall this event?

Shih-Yu Lo replied to Marco Bertolini
You mean there are biases in that book?

Keep trying!

For additive mixing, the three basic colours are red, green, and blue; for subtractive mixing, the three basic "subtractors" that can absorb red, green, blue. The materials that can absorb red lights appear to be green; the materials that can absorb green lights appear to be red; the materials that can absorb blue lights appear to be yellow....
-
Thanks for your question! You just raise an important topic that we didn't have time to explain in the course videos, as it's a bit complicated.
Actually there are two types of colour mixing: Additive and Subtractive.
The colour mixing we introduced in the course as well as the exercise is "additive mixing," which applies to the context when you have...

If you have watched all the videos and completed all the activities, I really appreciate your efforts and your perseverance. To be honest, the contents of this course are a bit challenging and some topics could be a bit dry for some people.
If you didn't get all the details about those complicated theories, that's fine. But I hope that the thing that you...

Shih-Yu Lo replied to Tom Halsall
Yes! In a way seeing can be regarded as a reciprocal process between the physical properties and the perceiver's knowledge. A particular object in a scene can trigger a certain kind of knowledge, and this knowledge can facilitate the perceptual processes for other objects that are related to the first object.
-
That's a sweet story.
-
Shih-Yu Lo replied to Tom Halsall
Your belief of "human brains are hard-wired to see patterns" is a widely accepted view about human vision. But there are multiple ways to interpret such a phenomenon. Some people believe that it's a product of evolution; the visual system has evolved to automatically give meanings to whatever we see in order to survive. Another way to look at it is through...
-
I am really fascinated by your observation. But I want to make sure you and I see the same thing. You mean, if you focus on something, say, object A, while attending to something else, say, object B, between you and object A. If you look at object A "hard" with the left eye, object B appears to shift slightly to the right? And it will shift to the left if you...

haha.....they certainly have their own way to perceive an apple.

Shih-Yu Lo replied to Tom Halsall
A possible mechanism is provided at about 3:32. Actually there are many types of after effects, and colour after images are just one of them. If you look at something moving upward for a prolonged period of time, when the motion stops, it will appear moving downward, and vice versa. Another even more tricky one is that if you stare at a man's face for a...

We can know that the world would be different if we had a different type of colour system. Unfortunately, there's no way we could know "how different" it would be.
-
The answer you tried to get from your friend is actually what fascinates consciousness researchers. There's no way we can feel how other people feel. It's hard for people without colour deficiency to feel the way how people with colour deficiency feel. But actually, even for two people who don't have any colour deficiency, they might not see the world in the...

Sorry for the late update. Also, here's another instruction that might help you find the blindspot:
There are 4 pages in the file. In the first, second and third page, there are a circle and a cross, but they are different in color or background.
1. Let’s take the first page for example. Please place the slide in front of you, the distance could be...

Thanks for your opinion. If my understanding is correct, you think consciousness still needs some kind of "hardware" to achieve. But maybe that hardware is not a brain. Is my interpretation correct?
-
Indeed. The brain is important. For most people, seeing starts from an external object, but you raised an important point: The brain (or the visual system) is starting point of "seeing." But still, we are not sure whether seeing is only limited inside the brain.
-
Thanks for sharing your opinion. I am curious to know whether you think the "mind" is the brain, or the mind includes something else?
-
Thanks for sharing your opinion. I really like the metaphor you use: " the brain "holds" our consciousness/mind like a vessel." I am also curious to know whether you think the brain is necessary for consciousness? Can consciousness exist without a vessel to hold it?
-
Thanks for sharing your opinion. I think your view is the predominant view in psychology as well as neuroscience.
-
Thanks for sharing your opinion. Indeed, from basic instincts all the way up to "culture" are all somehow involved in "seeing". As regard to whether the brain as a "control" system, it's an interesting question. Personally, I think the term "control" implies some degree of voluntarily, but actually we are not sure whether the brain is the central commander...

@elainebreinlinger Thanks for the question. But can you elaborate a bit more about your question?

I find there are two kinds of sufferings. One suffering is solvable; for example, you have a certain pain in your body, or you have certain stressful task to complete. For this kind of suffering, I would force myself to "do" whatever I should do. Another kind of suffering is unsolvable, like, you have certain worry that you can't do anything about, or you have...

Hi all! I am Shih-Yu Lo from National Chiao Tung University, Taiwan. I am currently an associate professor in psychology. I would want to know more about Buddhism and its connection with the human mind.
