Children's Learning & Development

Latest news

  • Brain imaging has revealed that aerobic fitness and motor speed/agility in overweight children, but not strength, is associated with greater gray matter in some brain regions, some of which are also associated with better academic performance.

A Spanish study involving 101 overweight/obese children (aged 8-11) has found that aerobic capacity and motor ability is associated with a greater volume of gray matter in several cortical and subcortical brain regions.

  • A large study has found higher levels of traffic-related air pollution, still within the EU safe limits, are associated with slower growth in working memory capacity in primary/elementary school children.

A Spanish study investigating the effects of traffic-related air pollution on children walking to school has found higher levels of particulate matter and black carbon were associated with decreased growth in

  • A largish study involving school-age children not at any particular risk has found that higher levels of air pollution experienced by the mother during pregnancy are linked to less gray matter in some brain regions.

Research using data from a population-based birth cohort from Rotterdam, in The Netherlands, has found that children exposed to higher levels of air pollution when they were in womb had significantly thinner cortex in several brain regions.

  • A study has found that having more than one illustration results in poorer word learning among pre-schoolers — but this can be mitigated if the reader draws the pre-schooler’s attention to each illustration.

When you're reading a picture book to a very young child, it's easy to think it's obvious what picture, or part of a picture, is being talked about. But you know what all the words mean.

  • A comparison of non-interactive electronic books and their print counterparts has found that toddlers learned more from the electronic books, but this was accounted for by their greater attention and engagement.

A new issue for parents to stress over is the question of whether reading digital books with your toddler or preschooler is worse than reading traditional print books.

  • Brain scans of children with sleep apnea have found extensive reductions in gray matter.
  • Recordings of brain activity show that children's brains respond to sleep deprivation differently than adults’ brains do, and that this is linked to myelination of nerves in a specific area.
  • Sleep assessment from birth to age 7 has found that children getting less than the recommended levels of sleep at age 3 and after, were more likely to have cognitive and behavioral problems at age 7.

Untreated sleep apnea in children shrinks brain & may slow development

Brain scans of children who have moderate or severe obstructive sleep apnea have found significant reductions of gray matter across the brain.

  • Finger tracing key elements in worked problems seems to help some students better understand and apply mathematical concepts.

I've reported before on studies showing how gesturing can help children with mathematics and problem-solving. A new Australian study involving children aged 9-13 has found that finger-tracing has a similar effect.

  • A small study found children who had experienced a sports-related concussion two years earlier still showed cognitive impairments, with younger children showing greater deficits.

A study involving 30 children (aged 8-10), of whom 15 had experienced a sports-related concussion two years earlier, and all of whom were athletically active, found that those with a history of concussion performed worse on tests of

  • A survey of US adults suggests worry about concussion goes hand in hand with a lack of understanding.

An online national survey of 2,012 adult Americans (of whom 948 were parents) has found that, while the vast majority (87%) don’t know the definition of a concussion and many don’t know the injury is treatable, there is a high level of concern and even fear across the country.

  • A large study found teenagers' grades suffered significantly and linearly, for each hour spent watching TV, using the internet or playing computer games.
  • Of these activities, the most harmful was watching TV.
  • Hours spent doing homework or reading for pleasure were each associated with a significant increase in GCSE grades.
  • The amount of moderate-to-vigorous physical activity had no effect on grades.

A study involving 845 secondary school students has revealed that each hour per day spent watching TV, using the internet or playing computer games at average age 14.5 years was associated with poorer GCSE grades at age 16.
