Everything is interesting! ARTexplains looks deep into psychology, science and history for the crazy cool facts and stories that make you go "Bwuh?"

No topic is too outlandish! Psychological Fallacies, Mental Health, Anatomy, Optical Illusions, Neuroscience, The Lost Empire of Yam... Take a look! It's like an encyclopedia with all the boring pages torn out!

And it's scholarly! Research and citations included in each educational video's description!

The host of this channel has a ligament of the human body named after him thanks to his episode on Belly Buttons, some undirected Wikipedia vandalism, and a top-tier medical journal: "the Xander ligament."

I believe that I have aphantasia, although I can sometimes visualise things it’s basically exclusive to places. If you asked me to describe the faces of family I could only provide the most basic description. Even when I can visualise objects it’s only faint, I couldn’t tell you the colour of an object and would struggle to rotate it in my mind.

Well done, and very interesting, one thing you got wrong, saying conservatives expulsion of immigrants and building a wall because, dusgust, I think it's more, conservatives disgust of breaking the law, the wall isn't ment to keep immigrants out, it's to stop illegal crossing into a country. Conservatives have no disgust of immigrants, the disgust if from breaking laws ment to keep citizens safe. A country needs to know who is living in the country they immigrated to. The United States is the most welcoming of immigrants out of all countries. I think your own disgust of conservatives have tainted your view of them.

I don't think I have aphantasia, but I have always struggled creatively. I can visualize an apple and rotate it with some effort. I can imagine what I look like dribbling a basketball between my legs. I create a mental image of characters in a book. But I don't actually see it in the same way that it feels like i see when I dream. When I am sleep deprived, I visualize more readily and, it can feel like I am not in control of them. Like the visuals are forming my inner monologue as opposed to my inner monologue forming the visuals.

I'm over 40 years old and only a couple of years ago I realized that my mind is both blind and deaf. For me the word "thought" has always meant a kind of an impulse of information. It seems to be mind-blowing for many people to find out that it's entirely possible to think without "converting" the information into sound or pictures. And now I also realize that many people meditate for years and years to achieve a state of mind that I have every day. I always wondered how it seems to be considered nearly super-human to "quiet" or "empty" your mind.

When i tell you i was SHOOK when i found out people actually see things with their eyes closed🤯...I see NOTHING just straight ⚫️. I just rest in the feeling of things, I conceptualize an image but i don't actually see it. I dream pretty normal but meditation & things where you have to conjure an imagine in your mind? nah. I wish! I can feel the feeling of seeing it..if that makes sense😂 I'm very emotion/ other sensory based when 'visualizing'. Damn i'm kinda jealous of other people's brains🫠😂 I bet their meditations & visualizations Slapp!!✨️ Also, I don't have an inner monologue that people talk about having. Alot of the research I've done shows a link between that and aphantasia. I'm so curious how that works.. like people hear a voice in their mind 24/7?? Is it yourself or like disconnected from you? What's it talkin about?🤔😅 like i'm genuinely so curious! I have thoughts i think in my mind but i don't audibly hear them.. Alot of people I've asked say it can be annoying and very self critiquing even mean at times which sounds Awful😟😣honestly just the thought of it in general kinda freaks me out😬 like constant chatter all day everyday only you can hear? I'd go insane..both of these concepts really fascinate me to no end!!😌 the human mind is so complex! Quite interesting.. I could talk psychology & neuroscience all day💯

I found out I had aphantasia several years ago and the concept of people actually being able to SEE things in their head blew my mind; like you, I always thought phrases like “picture this” were metaphorical I tend to have extremely vivid dreams and have a “vivid” imagination but I was in probably my mid twenties when I found out most people can voluntarily create mental imagery and it made me feel like I was playing life on hard mode 😆

Im not sure about it. I can see things in my mind but they arent very stable, they morph into other similar things or disappear. If people can imagine with high detail and stability then why play videogames and watch movies if you can create whatever you want in your mind at will? It just doesent make sense . Imo its just peoples expectations and communication barriers, aphantasia is extremely rare

Yeah I'm a black screen. Feels you exist within a cavernous space like a workbench where faded conceptuals live. Possibly images are flooding all brain types on subconscious but my back - front cortex is weak AF. Recently I've worked the muscle and image streamed. Mind altering effects such as herbal tea or indica THC can bring on animated, key hole sensations like SMOOTHED OVER gradient gif images. And psychedelics can create geometric beauty like hippy matrix code. I'm the type from birth, congenital, so I had pure control over, could flex into full red screen, full grey screen, full white screen, default resting black. Also looking back at memories as a kid, the way it seemed to work for my memory minds eye, the general shape of the environment and the positioning of the actors, body language ECT...were there. What happened is recorded journalistically while integrating. I had very vivid super reality imposed looney toon psycho killer waking sleep paralysis in which my father superman carried me to his bed. I saw a beautiful woman in a painting of his, animate up her stairs in her white fluttering dress as he lowered my still dream stunned body into his bed. It's actually nuts how isolated I feel. But it has honestly kinda empowered me. Apparently scientists tend to be aphantasic in higher percentages than genpop, and that makes ALL THE SENSE to me. But so far, maybe only my aphantasic brothers and sisters would get WHY it makes sense :P Namaste from the Lonely Island Aphantasic xo

All so what are dreams and if we were in base reality then we would be true infinite sentient energy yet if that was the case then there would be no off switch to that yet we have discovered that we can in fact turn off our consciousness using drugs and where do we go then cause in those situations it’s not sleep and brain eeg shows that and we loose all sense of space time and self just enter and exit a black hole of nothing when we are put under. So that is one proof that we are not in base reality or that would not be possible.

Does it refresh when she blinks? What's the maximum rate she can blink at and have it refresh? What happens when she moves her head?
@ARTexplains
@ARTexplains 3 месяца назад
These are great questions, but the studies by Zihl don't specifically answer them, unfortunately. To speculate on the blinking questions, I would say that because her visual reaction time seems undamaged (reported in Zihl et al., 1983) and her other temporal abilities seem intact (see Zihl & Heywood, 2015), blinking should assist in resetting the "static" image that she can currently see. I don't see a reason why her "refresh" rate from blinking would be different from the average person's, but as far as I know, it wasn't tested. In the literature, it is noted that people with akinetopsia usually try to compensate with hearing and touch, and I haven't personally seen discussion of a person coping using strategic blinking. As for the head movements, I was unable to find a discussion of that, so that's a big question mark for the moment.

Was she immune to motion sickness? Or would this cause more motion sickness?
@ARTexplains
@ARTexplains 3 месяца назад
Excellent question! Because motion sickness results from disagreement between a person's vision and vestibular senses, it's plausible that she'd experience more motion sickness. In Zihl's 2015 article, he wrote: "...she had difficulties keeping her body in balance because of interference of visuo-vestibular interactions with visual stimulus movement..." -- and I believe that supports the idea that she was more likely to experience motion sickness. However, I don't know of any more specific discussion of Akinetopsia and motion sickness, so perhaps more research is needed on that front.

What makes them pseudohallucinations? Are they not the real deal?
@ARTexplains
@ARTexplains 3 месяца назад
They are pseudohallucinations because the person is aware that the things they are seeing (such as the lions) are not real, and therefore they vary from other situations in which a person truly hallucinates and is unsure whether the image is real or not (or in some cases, completely believes the hallucination is real, such as in severe schizophrenia).

The case was published in '87 but the key events took place in '86 -- you can read the references for yourself in the video description.
