Helping the faceblind see - U of M and prosopagnosia
Summary
TLDRProsopagnosia is a condition where individuals cannot recognize faces despite seeing features like noses or mouths. They can identify expressions or characteristics but struggle to distinguish between different people. This research focuses on children with prosopagnosia, aiming to study how face recognition develops. Children participate in memory and discrimination games to assess their abilities. The hope is that early intervention could lead to better outcomes than adult treatments. Ultimately, the goal is to develop reliable identification and effective treatments for children with this condition, improving their social experiences and lives.

-Prosopagnosia is surprisingly common and may be as prevalent as conditions like autism, though it is often under-recognized.
What are the researchers' long-term goals in studying prosopagnosia?
-The researchers aim to develop reliable methods to identify and treat prosopagnosia in children, with the hope of improving their ability to recognize faces and lead better social lives.
Why is it important to understand developmental prosopagnosia?
-Understanding developmental prosopagnosia can help researchers create more effective treatments and interventions, which could significantly improve the quality of life for children with this condition.
Outlines
🧠 Understanding Prosopagnosia
Prosopagnosia is a condition that impairs a person's ability to recognize faces. While individuals with this condition can see faces and identify certain characteristics, such as expressions or beauty, they cannot recognize who the person is. This is because they are unable to process the complex relationships between facial features, which most people can easily do. The work on prosopagnosia primarily focuses on adults, but a developmental approach is now being taken to study its impact on children.
🔬 Studying Children with Prosopagnosia
Researchers are beginning to investigate prosopagnosia in children, particularly in the Minneapolis/St. Paul area. The goal is to study the typical development of face processing in children by conducting various memory and discrimination games. These games help assess how well children can recognize and differentiate between faces. The hope is that by identifying the condition earlier in life, more effective improvements can be achieved than when addressing it in adulthood.
👶 A Child's Perspective on Prosopagnosia
A child with prosopagnosia describes their challenges in recognizing classmates and others around them. They can see facial features like the nose and mouth but cannot differentiate one person from another. This leads to difficulties in social interactions, as they feel they may come across as rude or disinterested, despite wanting to engage with others. The child expresses how isolating and challenging this condition can be in everyday life.
📊 Prevalence and Goals for Prosopagnosia Research
Prosopagnosia may be more common than expected, with its prevalence being similar to that of autism. The ultimate goal of current research is to develop reliable methods to identify and treat prosopagnosia. By understanding developmental prosopagnosia more thoroughly, researchers hope to significantly improve the lives of affected children and help them manage their condition more effectively.

Highlights
Prosopagnosia refers to an inability to recognize faces, despite being able to see facial features and expressions.
People with prosopagnosia can detect emotions and characteristics like smiles or frowns but cannot identify the person.
The ability to recognize faces involves processing relationships between facial features, like the nose, mouth, and cheek structure.
Research on prosopagnosia has historically focused on adults, but now it's being approached from a developmental perspective.
Children from the Minneapolis/St. Paul area are brought into the lab to study the development of face processing.
The children participate in memory games where they are asked to identify faces they've seen before.
In discrimination games, children are shown a target face and asked to sort other faces based on similarity to the target.
The goal is to identify prosopagnosia earlier in children, with the hope that early intervention will lead to more improvement than in adults.
A child with prosopagnosia describes the difficulty of recognizing classmates, feeling unsure of who they are even in familiar settings like school.
The prevalence of prosopagnosia in children is surprisingly high, similar to the prevalence of autism.
One of the main research goals is to develop a reliable method to identify prosopagnosia in children.
Another major goal is to create an effective treatment for prosopagnosia.
Researchers hope that understanding developmental prosopagnosia will lead to interventions that help children with this condition live better lives.
Children with prosopagnosia face social challenges, often feeling isolated or misunderstood because they cannot recognize peers.
Achieving reliable diagnosis and effective treatment of prosopagnosia could significantly improve the lives of affected children.
Transcripts
Prosopagnosia refers to an inability to recognize faces.
So for somebody who has prosopagnosia,
they can see a face, they know that the face is there.
They can typically tell you whether the face is smiling,
that face is frowning, or that particular person is happy
or beautiful, all of these different other characteristics
but they cannot tell you who that person is.
The amazing thing that we can do with faces
that almost everybody can do, is put those properties, the nose,
the face, the mouth, the relations between them,
how hollow your cheeks are, just on and on and on,
and create a way to recognize the relationships between all
of those characteristics and take them in immediately
and remember that particular individual,
that particular person.
The work that's been done on prosopagnosia focuses on adults
and it's been going on for several years.
We're approaching the problem
from a developmental point of view.
We're interested in measuring and looking for children
that have prosopagnosia.
We're bringing children into our lab,
typically from the Minneapolis/St.
Paul greater area, and we're looking
at the typical development of face processing
in general in these children.
So kids come into our lab
and they complete a variety of games.
A couple of them are memory games, so we present them
with faces and then we ask them to identify the faces
that they have just seen.
Some are discrimination games, so they're shown a face
and they're asked to sort faces based on whether they're similar
to a target face at the top
so they're discriminating between faces.
Underlying idea is that if we were
to reach these children earlier than adults are being treated,
we're hoping we're going to see more improvement
than we're finding in research on adults.
I can see your face and all your features, like your nose
and your ears and your mouth, I just can't tell the difference
from your nose and face to another person's.
It's hard.
I don't recognize my classmates.
I don't know who's in my class.
I don't even know, like, I walk by them in the hall,
and there's a lot of people that I should know, but I don't.
So it's just really hard because I don't want to seem
like I'm rude or I don't want to be their friend.
I think that the percentage of kids
who have it is surprisingly high.
It isn't an extremely rare condition.
It's sort of similar in prevalence to autism.
I think one of the main end goals that would be fabulous is
if we had a way to identify prosopagnosia and if we
in a way that's reliable and if we had a way
to treat prosopagnosia that was effective.
If we could get those two things straightened out,
and throughout achieving those goals,
really get a better understanding of what's going
on in developmental prosopagnosia.
We're hoping eventually to be able
to really help these children
who have these serious problems do better in their lives.
