The Prosopagnosia (face recognition blindness) thread

[crazyaboutmika]

Dear Marilyn , it's good that you opened this thread, I had never heard about this condition and now I know about it . I can relate to this because when I was a teacher it was a problem for me to remember the pupils names, it took me forever to associate the faces with the names , but that's not much compared to face blindness which is certainly not an easy thing to live with

It's good that you have a sweet husband who can help you deal with it

Take care dear Marilyn

[Marilyn Mastin]

I read in a book about memory, that a good way to remember names is to attach it to an image or world it reminds you of.

For example, for my name, obviously, Marilyn Monroe.

I met someone called Nosa once, so I thought of No, then I could remember the rest of the name.

Some names are easier than others to link to something memorable, but I hope that helps.

 

I've looked on YouTube for videos about Prosopagnosia, but on my tablet it doesn't show the link, so I can't copy it. On the laptop, it did show the browser at the top, with the link and I could just copy it, and paste it somewhere else. But I can't work this kindle in the same way because I don't see the browser. But there are lots of things on there if anybody wants to look.

[zia Giovi]

Yeah it's really a good thing, also because for my personal way to work it's almost impossible for me to work on something I don't like, so it's way better for me this way, anyway I wouldn't have had help in any case because I'm in open number class at college, so it's already a challenge to find the relator for your thesis, be followed and helped just comes after, but I'm happy with how the thing are going for now, this forum and other things are helping me a lot!

I'm sad to hear about how did it go for you, it happened the same thing to me in highschool, but in that case I held hard and I continued to do what I wanted, unfortunately they have taken away many points in my final vote even though I had done a great job and not only on my accounts but also by the external teachers opinions, anyway it's done now I hope this time i'll be more lucky

 

For the library thing I think it is the same way as mine at college, that needs subscription but go on and a list if you can, it surely won't do any harm

 

My teacher never missed his receiving hours, he used to read every chapter in one week and he didn't change a single comma when I gave him the complete work: I cannot complain, after all.

My sister has a master degree in psycology and had the same problem as you: too many students compared to the available teachers, it was very difficult for her to find a professor and she had no support at all. Almost twenty years later, in a different University, I see that nothing has changed...

Memory techniques can be very helpful in many aspects of life, I think, but I am too lazy to focus on them.

We are very lucky in this respect nowadays, because scientific skills have improved a lot and can make everyday life easier with relatively modest effortless also for disadvantaged people

This is always so interesting for me too! I heard about the finding object situation as a consequence in prosopagnosia I must have surely something in my material, think it's in english too, and also something about TBC and genetic aspects, I'll look with more attention and let you, if I upload a scan of a page in a JPG file as a normal photo will you be able to see it with your tablet?

 

Thanks also for explaining the guides thing, i was almost there , and for what concerns black people perception of voices I think it's normal, because

it's not easy even for person without disorders, for you it's even more also because it's not part of your cultural background, so you don't have any kind of hint or basis for wich you can construct a recognition model.

 

And also your husband message is lovely and so inspired, you two must love each other a lot he's really kind and helpful and caring for you and your condition and also well informed because all he said is correct it's the step between what the eyes see and what you perceive when it comes to the brain, this part of the process in prosopagnosia is defective as if information is lost on the way.

I'm loving this thread. I also admire you so much for choosing something so medically unknown for your thesis.

This discussion is teaching me so much already and I'm sure, teaching others on the thread, a lot as well.

I had never linked my inability to locate objects, as part of Prosopagnosia, but then I read on one of the sites who's link is in the first post, that it's a part of it, for some people.

I think, an important point is that it's not the same for every sufferer. Some seem to see blankk faces with their eyes. So I think that's worse for them, than for someone like me.

Yes, Alan is very wise and perceptive. He's absolutely right. It's the link between my eyes and my brain that seems to be the problem.

I recently had a memory test. I was asked to draw two hexagonal shapes that were interlinked. The doctor drew it first, and then showed it to me. Asking me to copy it.

I looked away from the drawing, looked down at my sheet of paper. Took my pen and started to draw.

I honestly thought I had drawn it right. It was such a simple thing. But when the doctor showed me his drawing again, I'd made a big mistake! I had drawn the two hexagonal shapes, but I had drawn them far apart, not interlinked! I was shocked.

So my difficulties do seem to be linked some kind of communication problem between eyes and brain, rather than a perception problem, as it is for a lot of Prosopagnosia sufferers.

 

I would probably have to borrow my son's laptop if I can't see something on this tablet. My computer skills really suck though.

Wow - this thread seems very interesting!! But it's quite a lot, so I'll read it all when I find time for it ...

Not it has not changed a bit sadly, but I can't complain too my relator is one of my favourites professor, though this is kind of a second choice because she teaches General psychology, the 1st you study when get into college, and I'm more into neuroscience but i got to do something interesting anyway, so I'm happy even if it's gonna be a long work

I will try to look something on youtube and post it, if it's in english or with subtitles

 

Thank you Marilyn I'm learning new stuff everyday too, i fave the link to this thread to my relator too, if she will ever read something will ad it that too, anyway there is enough material to study and write on but you have to know where to look for it, most of the time is inside the different colleges or research lab and so most of the time you have to pay to read it, for subscription or downloads, it occurs bè tweet the 10 and 20 years for something to ne published on books for something more than just a mention, for now i have a few article s from the magazine brain an italian ebook specific on Prosopagnosia and a copule of thesis were there are some chapters that i coul use I'll try to post some screen of the english ones

 

I think it's better for you to see face characters and not recocognize them instead of seeing just face shapes with out characters that must be really terrifying, I remembered i had a nightmare once where people around me had question mark instead of their faces, I al most cried when i woke up!

For the object shape test and memory test you have to try the gestalt tests on perception and see wich one you fail, I think it would be really useful, to know if you have problems only in interlinked figures or something else too

It's about communication for sure, i hope to find something useful in the material I have

 

Wow - this thread seems very interesting!! But it's quite a lot, so I'll read it all when I find time for it ...

Come back whenever you want

[FralovesMika]

I don't know when I'll be back tomorrow because in the afternoon I'm getting a new tatoo, and Idk wich time I'll be home, see you later!

[Marilyn Mastin]

I've been thinking a lot about my life, and how Prosopagnosia has affected it, so I could share on here.

I have a sister, two years younger than me. As children, we hung up pictures of pop stars and actors on the bedroom wall.

She did it because she fancied them. I did it because she did. Sho was normal. I wasn't. So I tried to appear normal.

It was me not recognizing faces on TV that first made my mum realize something was wrong. I was obviously born with the condition.

Because the faces on TV didn't stick in my memory, I didn't have the crushes that young girls have, for boybands or singers, or actors.

But then, as a teenager, I fell madly in love.

Who was it? You ask.

It was Mr Spock!

He, of course, had a lovely voice I could recognize, but more than that, of course, he had those huge ears and odd shaped eyebrows. I could always recognize him.

I never thought about it at the time, but everyone I've loved on TV have always looked different. The Lion Man Vincent, from the 80s series Beauty and the Beast, several from Star Trek, and Robocop from the TV series.

I got to love Mika from the radio. I loved his voice and song. It didn't matter what he looked like.

I thought I'd share this with you all.

[Log lady]

Marilyn, I have just finished going through all of your posts here and I'm honestly blown away from what you've been through. I'm glad your life is a bit esasier now you've been diagnosed.

I've been very moved by your stories. Some of them are sweet and sad at the same time, like the one about your crushes... or the one about how you weren't able to recognize Mika and remember his face, but his voice has stuck to you for good.

I've studied neuroscience too, at med school. All in all, tuberous sclerosis has a great variability of expression, so it's good you don't have many other terrible issues that are related to this pathology, such as mental delays, seizures, kidney and eye conditions, etc. But it sucks you don't have access to the studies there.

Thank you for sharing your story, it's amazing to find out how much strength you have.

Actually, I've had two cataract operations. Both eyes were affected by the time I was in my 30s. But the ops were successful. My Tuberous Sclerosis caused it.

I do have issues with depression and anxiety. I also become very confused. This is why I find computer skills hard to obtain. My brain just goes blank.

It's also why I can't work. I tried to work in a charity shop to see how I would do, but when people would be coming to the till, one after another, I couldn't cope. I just, kind-of switched off. I did work experience in an off license (liquor store) but I asked the same person, on several occasions, for her ID, and she got annoyed with me. But of course, it was because I had forgotten her face.

I was suspected of having epilepsy for many years. But it turned out that I didn't. But my anxiety disorder does cause problems that are similar, and I can't multi task, if I try I just switch off for a while. I kind of, stare into space and can't do anything for a while, until my brain sorts itself out.

Obviously, I can't drive.

But don't think I am unhappy. I'm not. Especially at the moment, with this thread, I really feel like I am some use. If my experiences help others, I am so pleased about being able to share my stories. I've been blessed, by God, with my good writing skills and I'm glad I can use them.

I also have my faith. I am a Christian and my faith has helped me all my life.

I also have a wonderful husband, and a son that I am deeply proud of.

I'm also a member of the best fan club, for the most wonderful star on the planet. So I think I'm very lucky.

Now I've read everything written on this thread, and I must say I'm impressed - both by FranlovesMika, who dive into this subject, and writes a thesis on the condition - and you Marilyn, who share this privacy, it's so kind and nice of you !!

I've never heard of it before, and I can only try to imagine what kind of challenges it means, to suffer from this. You're a truly amazing woman - and I think that we all are the lucky ones, to have you here, so active, on MFC!! Lots of luck - to both of you!!

Of course it was hard for you, you just did the same thing to try to be and feel the same as your sister, in the reality it was easy for you to recognise and appreciate voices or particular characters, I think you were lucky knowing Mika also for this you surely appreciate him more than others both for empathy and the voice, his amazing voice you surely perceive a lot more than other people on that, i think it's impossible not to love him in the end

I'm really happy to be able to share on here. I've had years of people not taking me seriously or implying that I'm making it up.

It's good to be able to talk about it. I think it will help raise awareness of the condition for those who read this thread, and if someone else has the condition, they will recognize their own symptoms and know they are not alone.

I've heard of the eye-movement theory before. But when I look at a face I do make a conscious effort to keep my eyes on the face and not move them.

It doesn't make a difference with me though, because once they walk away, I forget the face. So for me I don't think eye-movement is the issue.

But it could be the issue for people whose Prosopagnosia is not based on memory. A lot of sufferers seem to see blank faces. I don't. I see a normal face, but each time I see a person's face, It's like seeing it for the first time. I don't have a memory of seeing the face before.

I'm pasting a list of articles, hope you find something helpful!

I hope everything is going well for you. I'm sure you're thesis will be brilliant!

 

I've found an interesting video. A stroke victim who developed Prosopagnosia.

She's very positive about it.

She didn't recognize herself in a mirror when out shopping.

I don't have that problem, because I tell myself each day, what I am wearing. It's the same technique I use for recognizing anyone else, like if I'm separated from Alan in a shop, I remember what he's wearing, and Alan is overweight, so that helps.

When I look at the mirror at home, I know it's me, because I'm looking at a mirror. I check my hair and clothes closely, and as far as I know, it works for me when I'm out of the home.

Some sufferers see an object and think it's a person. I don't, thank God.

Here is the video

Good luck Francesca.

This is all quite a journey for me too.

It's made me look at my life and realize about the coping strategies I've developed, without even realizing they were strategies.

For example. At the beginning of the thread I said I don't have a problem recognizing myself in a mirror. But Alan has always noticed that I spend a lot of time looking in the mirror at home, and stare into every mirror I pass, when I'm out with him and notice a mirror.

 

Since the thread started, I've been conscious of doing this, and I've realised it is a coping strategy. I'm checking myself, to see what I'm wearing and what my hair is like today. Because I've had the condition all my life, I haven't always been conscious of the development of strategies, for me it's just normal behaviour. But now I realize that so many of my little quirks are actually ways of coping with my condition.

Hi everyone! This is an interesting thread. I've tried to read your discussion but haven't had time to write any comments before this, sorry about that. Wishing the best for your thesis, Francesca!

 

I'm familiar with this issue as my 15 yo son suffers from prosopagnosia. I realized it during his early years as it was obvious he could recognize our neighbour and their kids in their yard/garden but had no idea who they were when we met them at the supermarket or play ground further away (he connected them to their house). Similarly, he could recognize our close family but not for example his godfather or some other relatives and friends even met them regularly.

 

However, my son had a lot of autistic spectrum challenges so not recognizing faces was only one challenge among many other social difficulties (like not recognizing facial expression, tones or emotions, late talking, difficulties to communicate etc). At school he learnt to cover this difficulty and recognize people simply by learning to remember their hair styles, eye glasses, clothes etc.

 

He is intelligent and advanced in many other areas and has a very good memory so sometimes I forget how challenging and tiring it must be for him not be able to easily know who people are (for example after all these years he still can't recognize all his classmates if randomly met them somewhere) and I need to remind myself to be more understanding and to give him enough time to rest after meeting a lot of people.

 

Spreading awareness is the best way to help people with prosopagnosia, imo. If other people know someone suffers from this condition they can go and introduce themselves in new situations to avoid any misunderstandings. Good luck Francesca and thanks for sharing your experiences, Marilyn!

God bless you and your son. My mum was the first person to realize something was wrong. People used to go up to her in the street and say that I had ignored them. It was because, like your son, I couldn't recognize the neighbours when they weren't in their gardens. Mum knew I wouldn't ignore them on purpose, but couldn't figure out why I said I hadn't seen them

We got our first TV when I was about 10 years old, and used to watch the old Westerns in Black and white. So all cowboys looked alike to me and I was forever asking my family, "which one is he?" Even now, with colour TV, if two characters in a show are similar looking, with similar voices, I can't tell who is who if they are not in a scene together. So I tend to be about two steps behind my family, in understanding the plot.

Anyway Mum figured it out. She realized that when I was out on my own, this was when I ignored people. When someone else was there, I didn't, because my companion would say "hello Mrs Smith", and then I would know who it was. But even though she told the doctor and the hospital, they took no notice, so I had to learn to live with it. Most people never knew I had a problem. I used other identification methods or just bluffed my way out of it.

It's so good to be able to get the condition better known. It will help others like your son, and anyone who has it in the future.

I know it's one of the problems for people with Autism. I also know Autistics often have wonderful memories in other ways, and are very intelligent. I wish you and your son all the best wishes in the world.

Thank you so much, Marilyn. You are very brave and I can't even imagine what you have been through growing up when this condition wasn't recognized as it is these days.

 

My son got his Asperger diagnosis when he was 6 yo before starting his school. I can remember his first school day like yesterday, the first years at school were very hard for him even with a full-time personal assistant as he had to learn so many social skills people usually take for granted. He has done amazing progress since then and is now a smart teenager who is finishing his school with good grades in two weeks and starting a high school in August.

 

I burst in tears every time when I think about his progress and growing up (it's very emotional for me as a mother) and feel deep gratitude that we have been so incredibly lucky to have good, experienced doctors and understanding, supportive teachers to help us during these years.
