Over the past few months, concern has been raised regarding the effects of teachers and learners having to wear masks throughout the school day.  Some research studies have been done. There are reports that masks may hinder children’s ability to recognise faces and read emotions correctly without facial expressions.  In addition, verbal communication, often needing visual observation of a speaker’s face, may be affected. But, according to an article appearing on February 2022 in MedicalXpress, experts are divided on the long-term effects on children’s development. The article follows (author unknown):

Learning language

The first fear concerns the learning of language, which takes place in the first years of life. Children learn to speak through social interactions, and in particular look at the mouths of adults in order to dissect syllables.

This path being blocked, it seems logical to suppose a harmful effect.

“You do look at faces when you’re learning to talk,” Diane Paul, of the American Speech-Language-Hearing Association (ASHA) told AFP. “But it’s not the only way.”

Children also learn by listening to the voices and following the gestures and eye movements of those around them. Paul notes that those with visual impairment also learn to speak well—and that masks are not worn permanently, for example at home.

“At least at this time, there aren’t studies that have directly assessed the long term impact of speech and language development when young children interact with adults who wear masks,” says the expert.

“But there are studies that demonstrate that children can tune into these different communication cues and gestures when an adult’s mouth isn’t visible.”

A 2021 study demonstrated that infants were able to recognize unique words through a mask, just as well as without. But according to another, conducted in France, masks can interfere with learning to read among children with learning difficulties.

In general, research remains rare on the subject. But, says Paul, “I really do not see any cause for alarm.”

According to the US Centers for Disease Control and Prevention (CDC), “the limited available data indicate no clear evidence that masking impairs emotional or language development in children.” 

The agency recommends masking in public for those aged two and up, while the World Health Organization suggests the age of five.

Social and emotional development

But among psychiatrists, the story is a little different.

“More important is the emotional side,” says Manfred Spitzer, who’s also a specialist in cognitive neuroscience at the University of Ulm in Germany. He notes that the first thing lost with a mask is the sight of a smile.

“In educational settings, there is a lot of implicit feedback back and forth between teacher and child,” he told AFP.

“If you impair this ongoing communication, you will certainly interfere with successful teaching.”

Fears also relate to the ability to form social ties. Numerous studies have shown that masks make it more difficult to identify faces and emotions, including—or even more—among the youngest.

But conclusions about the consequences differ.

A study of children aged seven to 13, published in the journal PLOS One, confirmed that emotions (fear, sadness, anger) were less well identified when a person wore a mask—but with similar results compared to wearing sunglasses.

It concluded that “masks are unlikely to dramatically impair children’s social interactions in their everyday lives.”

Yet other work, published in Frontiers in Psychology, has shown that performance in identifying the emotions of masked people dropped significantly between ages three and five, results that “suggest that we live in a time that may potentially affect the development of social and emotional reasoning,” the authors said.

Carol Vidal, a psychiatrist at Johns Hopkins University, said that she’s concerned at a societal level, though parents shouldn’t panic.

Vidal is part of a group of medics and scholars called “Urgency of normal” calling for the lifting of compulsory masking at school, where it’s hard to maintain the stringent use of masks anyway.

“I just think they’re not necessary at this point in the pandemic, knowing what we know about the risks for kids in terms of COVID, and knowing that we all have access to vaccinations, and that if we’re concerned about our health we can wear N95s (high-caliber masks),” she tells AFP.

It boils down to balancing risks and benefits, she stresses. The downsides of masks “might not be dramatic in the sense that you might not have effects right away, but I think we have to be careful,” said Vidal.

 

Martin Doherty, writing for The Conversation, says that at the age of about four, children reach important milestones in brain development.

One of these is a huge improvement in understanding others’ thoughts and feelings. This is the start of empathy.  Another is in spatial thinking—understanding how objects are positioned and related. This is the beginning of the ability to read maps.

Martin and his colleague, Catherine Sayer, conducted a study with 175 two to five-year-olds to explore how children are able to use scale models to figure out where something is in the real world. At about four, children are able to use a scale model of a room to work out where something is. We thought that this might result from children’s understanding of how one thing can represent something else. But we actually found that four-year-olds’ ability to use scale models came from their spatial abilities.

At the same age, children start to understand that someone’s behaviour is due to what that person believes, not necessarily what is really the case. This has interesting consequences.

If you’ve played hide-and-seek with young children, you may have noticed that they aren’t always very good at it. They love the ritual of looking in all the wrong places first, but beforehand they may tell you where they are going to hide, hide in the same place every time, or not be especially hidden.

After their fourth birthday, they get much better at hide and seek. They understand that the seeker looks in the wrong places because they don’t know where the hider is.

At about three to four children also start to tell lies. They realize they can make someone believe something that isn’t true.

Understanding symbols

Martin’s earlier research with fellow psychologist Josef Perner suggests that four-year-olds don’t just start to understand how others’ minds work. Figuring this out is part of the development of an understanding of “representation”—that symbols, like thoughts, words, or pictures, can be used to stand for something else.

Children start to think about how words relate to objects. This means, for instance, knowing that “animal” can refer to something you already have a name for, such as “rabbit”. This might help children learn the new word.

Their ability to use a understand the components of pictures also improves around this age. Very young children use a lot of trial and error to complete a jigsaw, picking up random pieces to see if they fit. By the time they are about four years old, they start to use the picture as a guide, trying to connect lines and match bits of colour, while checking the guide picture on the box lid.

Developmental experiments

Another ability children develop at around four is using scale models. A classic set of developmental experiments involved a model of a regular household room. The real room had typical furniture—sofa, table, cupboard and so on—and the model had miniature versions laid out in the same way.

Children were shown where something was hidden in the model and told to find an object hidden in “the same place” in the room. Children of around four can find the object using the identical layouts. If shown a sticker under a particular chair in the model room, for example, they can go straight to the “same” chair in the other room. This is the fundamental understanding required to read maps.

Adults see scale models and maps as representations. Maps represent a town or a country. A scale model of, say, the Eiffel Tower represents the real thing. At first, Martin suspected children’s ability to use scale models is more evidence of understanding representation at this age.

He was wrong. Instead, the researchers found that this ability is based on a development in children’s spatial abilities that also occurs at about four. This is the ability to think about spaces and where objects are within them. Spatial abilities help with maths skills, and good spatial ability is linked to an interest in science, technology, engineering and mathematics.

Their experiment was simple. They compared the model room task with a test of understanding how representation works. The two abilities develop around the same age, but they found they were not related. Children who could do one task couldn’t necessarily do the other.

They also had a test of purely spatial ability. Children who passed the model room task also passed the spatial task. So it looks like the model room task relied on children‘s spatial thinking.

They don’t yet know why two important but apparently unrelated abilities arise at the same time. Perhaps it’s related to changes in the growing brain at this  interesting age.
