Curious Brains

Professor Derek Bell from Learnus (one of CEN’s collaborators) gave a presentation last week at the Second Neurocuriosity Workshop, on information-seeking, curiosity and attention. The workshop was hosted by The Centre for Brain and Cognitive Development (Birkbeck) and brought together cognitive neuroscientists, psychologists, and educators interested in the role of curiosity in learning.

Given Learnus’ mission – to facilitate in the translation of research to educational implications and practice – Derek’s talk focused on how scientific research in curiosity might help answer the perennial teachers’ question, “So what do I do in my lessons next week?”.

Derek emphasised that the link between education and neuroscience is not a simple straight line. While there is an appetite among teachers for new methods stemming from research on the brain, this places a responsibility on those working in the field to assure the quality of the information that is shared. Derek focused on key questions including: What is curiosity in the classroom? How does it differ from interest? How can curiosity be harnessed for learning? How does the neuroscience understanding of the basis of curiosity (in exploration, information gain, and reward seeking) link to classroom learning activities?

He drew some tentative conclusions from the research presented at the workshop: Curiosity consolidates learning. It may act as a positive feedback loop, with curiosity stimulating learning, and learning in turn stimulating more curiosity. However, curiosity, surprise, rewards and memory are tightly interlinked concepts. Practical strategies to stimulate curiosity and generate interest in lessons might include the use of surprise items and events, rewards, and questions.

But also he also stressed the importance of dialogue between different professional communities to facilitate understanding the concrete implications of cutting edge research, and whether they yet justify any major changes in teachers’ practice.

In the following discussion, two points emerged. The first concerned the challenge of ‘bringing curiosity to the fore’ and the suggestion that having some structure or task to help focus the curiosity might be more productive for students than situations in which the questions are completely open or students engaging in what might be referred to as ‘idle curiosity’.

The second was the idea that curiosity is not a ‘one-off event’, so there is a need to explore ways of sustaining curiosity so that it becomes a longer term interest in the material and, more broadly, in learning about the world and how it works.

CEN Research Seminars – Autumn programme

The CEN research seminars will recommence next week on Thursday 13th October at 4pm. These seminars are open to anyone with an interest in educational neuroscience, including educators and members of the public. The seminar series will run weekly during term time, and will be held in Birkbeck, University of London.

Some of the upcoming talks: Thursday 13th October 2016: Prof. Michael Thomas “Is educational neuroscience all it’s cracked up to be?” Later in the term: Prof. Ted Melhuish “Long-term effects of early years experience”. Discussion paper: “Genomic basis of educational attainment”

Can fish oil supplements help children with reading?

Can changes in diet improve children’s cognition? Everyone agrees that in one way or another diet has an impact on children’s cognitive abilities. Although there are many studies exploring links between diet and behaviour, there are also lots of holes in our knowledge.

One area of particular focus has been the claim that ingesting fish oil supplements either boosts learning in typically developing children or helps children with developmental difficulties, such as Attention Deficit Hyperactivity Disorder (ADHD), overcome behavioural problems. Fish and shellfish contain Omega-3 fatty acids, which, along with Omega-6, are known as essential fatty acids (EFAs). ‘Essential’ because the body isn’t able to produce them itself, but rather relies on dietary intake. EFAs have a substantial impact on how the brain functions. Despite the necessity of fatty acids for healthy brain function, the benefit of taking dietary supplements containing EFAs (usually Omega-3) has been far from clear. Few studies have shown robust effects of supplements in typically developing, healthy children. There is more evidence of the impact of EFA supplements in reducing ADHD-related symptoms in children with developmental disorders, although even here changes are relatively small and inconsistent.

In a recent paper, researchers reported evidence that taking fish oil supplements improved reading in 9 year old mainstream children in Sweden. The paper, by Mats Johnson and colleagues appears in the Journal of Child Psychology and Psychiatry. The researchers gave omega 3/6 supplements to 64 9-year-old-children in Sweden over a 3-month period, compared to a group of 58 children given a placebo. The control group were then given the supplements for 3 further months to see whether, if fish oils had an effect, these children then showed the same gains. A battery of reading tests (e.g,. of phonological skills, visual analysis skills, naming skills) were given to the children before and after taking the supplements. Parents also rated their children on various scales, including language and communication skills. From the battery, three tests showed reliable improvements of the supplements compared to the controls: phonological decoding time, visual analysis time, and phonological decoding. The reading benefits were stronger in poorer readers, in boys, and in children with higher ADHD symptoms (though no children symptoms marked enough to suggest a diagnosis of ADHD). Parent ratings did not show any changes (including in ADHD symptoms). The results suggest that while the supplements were effective in a mainstream school sample, they only benefitted some. They had stronger effects in the lower performing children, and diminishing returns in the better readers. This is consistent with the idea that in children who already have diets with sufficient essential fatty acids, supplements confer no extra benefit. However, children with attention problems in particular may show treatment benefits on reading.
