Lipreading training in deaf children

Let’s tell you a bit more about the research projects carried out at the CEN.

Today, we will share the outcomes of an intervention study led by Prof. Mairéad MacSweeney at UCL, and aiming at improving deaf children’s lipreading skills.

Many deaf children find learning to read to be very challenging. This project evaluated a computerized speechreading (lipreading) training program in a randomized controlled trial to determine (a) whether it is possible to train speechreading in deaf children and (b) whether speechreading training results in improvements in phonological skills and, subsequently, single word reading skills. 

Sixty-six deaf 5- to 7-year-olds children participated in the study. They became deaf before they were 12 months of age. They either took part in a speechreading intervention, or in a maths training intervention (active control group). The interventions consisted of computerised games that were designed to run across forty-eight 10-min sessions. Children were engaged in one session per day, 4 days a week, for 12 weeks.

Screenshots from the computer games used in the speechreading (a, b) and maths (c, d) interventions.

In the speechreading intervention, children saw a silent video of a model saying a given word, and had to choose the corresponding picture from a choice of four pictures. They also had to match visual speech patterns with letters and words. For example, seeing the video of a model speaking a phoneme (e.g, ‘p’) and choosing the corresponding letter. In the maths training intervention, children were presented with counting and arithmetic exercises.

Results showed a significant benefit of the speechreading training intervention on speechreading and also on their speech production accuracy. Importantly the speech production measure took into account both auditory speech and visual speech (i.e., articulation accuracy). The benefits of speechreading training were stronger when only children who completed the full 48 sessions were included in the analyses. These benefits however did not filter through to result in improved single word reading.

Although no effects were seen on reading skills, practitioners and parents of deaf children are likely to be interested in a game that can lead to speechreading gains in deaf children. Future research should explore whether interventions are more efficient for children whose speechreading skills are particularly low and also whether a longer training period would lead to subsequent gains in reading.

Éadaoin Slattery – Keeping Score! The development of a school-based attention training programme

Éadaoin Slattery is a PhD student at the University of Limerick. She is interested in the measurement and enhancement of cognition, with a particular emphasis on sustained attention, working memory and their interrelations. Her PhD research focuses on the development and evaluation of “Keeping Score!”, a novel, school-based attention training programme designed to improve sustained attention and working memory in children with attentional difficulties.

In her talk for the Centre for Educational Neuroscience, she first highlighted the relationship between cognitive assessments of sustained attention among primary school students, and teachers’ and parents’ reports of inattentive behaviour in everyday life – a first step in bridging the gap between lab-based research and school practice. Second, she reported the strong associations between: a) verbal IQ and working memory (e.g. the capacity to keep multiple pieces of information in mind), and b) word reading and reading comprehension. Finally, she presented an intervention, Keeping Score! aiming to improve children’s sustained attention and/or working memory. The intervention consisted in children playing table tennis, while keeping track of the scores. Although the programme seemed promising in terms of the ease to implement it in school settings, it did not yield significant improvements in working memory and sustained attention. Together with the attendees, Éadaoin discussed the methodological and practical challenges she faced (e.g. difficulty to have big sample sizes, to dissociate motor skills and attentional skills in the training programme). A lot of food for thoughts for fellow EdNeuro researchers!

What do kids want to know about their own brains? An interview with Tracey Tokuhama-Espinosa

traceytokuhama-espinosaTracey Tokuhama-Espinosa is from Berkeley, California and teaches a course at the Harvard University Extension School entitled Neuroscience of Learning: An Introduction to Mind, Brain, Health and Education. She is a former member of the Organisation For Economic Co-Operation and Development (OECD) expert panel to redefine Teachers’ New Pedagogical Knowledge which determined teacher need more training in Technology and Neuroscience. Tracey is the founder of Connections: The Learning Sciences Platform, which provides evidence-based resources to teachers. She has also taught Kindergarten through University and believes that the quality of education is improved through research, teacher education, and student support. In this blog post, she presents one of her on-going research project, which investigates what kids want to know about their own brain.

Thanks for taking time to answer our questions, Tracey. First of all, why did you develop this research project?

This research project was inspired by my many visits to classrooms. I am often called in to work with teachers, but I remind the schools of the importance of working with kids and their parents as well. There was one particularly wonderful class, a 4th grade room at Punahou School in Hawaii. When I asked the children what they wanted to know about their own brains, one little girl said, “I want to know how my head has enough space for my brain AND all of my imagination”! What a beautiful question.

This made my think of a study that Paul Howard-Jones mentioned once when we were talking about why people become fixed in their belief about how brains can do and learn, usually based on no evidence whatsoever. He suggested that there was a “theory of brain concept”, in which children around 8 or 9-years of age “decide” they think they know how they learn best, and then spend the rest of their life trying to confirm those ideas.

So… what do children want to know about their own brain? 

Curiously enough, there seems to be a pattern of response that parallels Howard’s thinking. That is, kids spend a lot of time thinking about how their brains work when they are very little, and then begin to conform to a pattern of thinking as they grow. The younger the kid, the more sophisticated the questions. By the time they are around 13, their words and questions are less imaginative and sound more like typical adult questions. To give some examples, here are some questions that arose when I visited a school last October, and talked with 12-to 13-years-olds.

  • Why do we get stressed?
  • How can we get enough sleep if we have sports and homework?
  • Why do people have sudden changes in mood?
  • How does our brain come up with dreams?

What was the most frequent question?

We are still doing data collection through June 2020, so I can’t answer that. I can say that there are a lot of questions about inner voice and self-talk, and also about how emotions play into behavior and learning.

Which one was your favourite?

I have to confess that I love questions about potential. For example, some kids want to know why they were “born” one way or another, and if there is anything they can do about it. These kids were 12 to 13 years of age. As you can see, they sound much like adults. When you get the smaller kids, you get more creative questions (like the one on imagination above).

Which one was the most unexpected?

The most unexpected were the disturbing ones. “Why do I think of killing myself sometimes?” for example really threw me. I also find it incredible that kids think their brains are somehow separate from the body. That is, they want to know why their brains don’t work when they don’t sleep well because they don’t see how they are connected.

Do we have sufficient scientific knowledge to answer these questions at the moment?

We have limited evidence to answer all of their questions, but we have a lot of directions we can nudge them in to find better answers. I like to say that we don’t know the answer, but it is a great question and some people would answer X, while others would answer Z. Then I ask them which they could believe and why. I think it is very important to fuel the fires of this curiosity with additional questions and existing hypotheses, and then push them to think a bit deeper about their own questions.

How would the answer to these questions be relevant to teachers?

By looking at what kids want to know about their own brains, they reveal a lot of unspoken conversations we need to be having in schools. Michael Merzenrich suggested that we should have a Brain Health class for all kids, around 8th grade (13 to 14 years of age), so they can understand the basics of the mind-body connection (how nutrition, sleep and physical activity influence their ability to learn), how emotions influence cognition, and better understand the different roles of nature and nurture, plus the role that making the right choice can play (free will). This study has taught me that kids have a whole lot of concerns and mistaken understandings about the limits on their own potentials that we can improve, just by sharing information. I think teachers would learn a great deal from reading the results of this study (or better yet, ask their own students the same question!)

Are there areas where you think research should focus next?

I am very enthusiastic with following up on Michael’s idea about Brain Health in regular schools. We don’t talk enough about the brain in schools, and many of these kinds of conversations between kids and teachers would go a long way in reshaping individual self-efficacy, growth mindsets, and so on.

Narratives and Mathematics by Jo Van Herwegen

cartoon_mathsAt first glance, it may look as if mathematics and narratives do not have much in common. Mathematics concerns itself with theory and facts whilst narratives can include fiction, fabricated characters and fantasy worlds. Recently however, there has been an increased interest within the academic world in the overlap between mathematics and narratives. This interest covers the mathematics of narratives, using mathematical ideas to study narrative techniques, the stories of mathematics teachers, and the importance of narratives in teaching mathematics.

Stories are powerful tools for learning for a number of reasons. People enjoy stories and stories can help to motivate learners when learning. Stories create more vivid, powerful and memorable images in a listener’s mind which helps both learning and recall. In addition, stories embed concepts within a context; this can make abstract concepts more accessible and helps show how concepts can be applied in real life. So according to recent research, narratives can be a powerful tool to teach mathematics.

Narratives as an anchor for mathematical development

Learning is not just some abstract thing that happens in the brain; rather, learning happens in the context in which a concept is used. Narratives can represent mathematical concepts through their prose, illustrations, logical development and context. An example of how narratives can be used to teach young children comes from a study by Kinnear and Clarke[1]. Earlier studies which examined probabilistic reasoning (calculating the likelihood that something will happen) in 6- and 7-year-old children had found that although children were able to use data to draw inferences,  when they explained their answers, they would use subjective examples from their own experiences and show little understanding of how they achieved their answer. Kinnear and Clarke used a story picture book including the character Litterbug who was first very wasteful but then learned about recycling and started to collect litter everywhere in the town. In their study, 5-year-olds were presented with the book Litterbug and a table with information about the rubbish that Litterbug had collected on Monday, Tuesday and Wednesday per type of items (e.g. 5 cans, two apple cores, three papers, etc). Children were then asked to predict how much of each litter category Litterbug would collect on Thursday. In contrast to previous studies which showed just data tables, children who were presented with the Litterbug story drew exclusively from contextualised knowledge of the picture story book to explain their predicted values when asked. This shows that children have the capacity and ability to draw meaningfully from data and use context knowledge to explain data observations if the connection to the data context source is indeed meaningful.

Since narratives are an integral part of our everyday activities, and our counting system is a cultural notation that has evolved as a result of these every day activities, it is not surprising at all to see that narratives are a powerful tool in helping children to develop mathematical abilities. There are a number of ways in which narratives can help mathematical abilities. First of all, narratives can teach children new concepts and promote mathematical reasoning. Secondly, they contextualise mathematical ideas as well as engage the child. Finally, they allow for rich discussions and wider exploration.

For example, a recent study by Carrazza and Levine[2] at the University of Chicago compared typical maths books that simply include sets of objects and books with the same objects and sets incorporated into stories (rich narratives) for numbers 1 to 10. They asked two groups of parents, one for the classic number books and one for the rich number stories, to use the books each day with their three-year olds. The researchers examined how well children could count and understand cardinality before they started using the books as well as after 4 days of using the books. Even though parents in both groups reported the same number of book reading sessions during the four days, children in the rich narrative condition performed better on the cardinality and counting task than those who used the simple pictures of the same sets of objects. This shows that embedding knowledge into rich narratives aids children in learning mathematics faster.

Storybooks as a way to develop mathematical vocabulary

Not only can the context help to embed knowledge and understanding, storybooks are also extremely useful in teaching children mathematical vocabulary. The development of mathematical vocabulary is important for young children as its use is necessary for them to reason and to understand maths. For example, when children learn that the words “more” and “less” can be used to describe number, they have a way to verbally explain the differences between a basket with ten apples and a basket with 5 apples. The use of storybooks that highlight mathematics vocabulary and explain numbers and how they relate to each other might help children “mathematize” or understand everyday situations in mathematical terms.

We can see then that while the richness of narratives allows young children to learn concepts faster and foster a deeper understanding of mathematical vocabulary, there is evidence that even just reading books, whether they have a mathematical content or not, influences children’s mathematical abilities.

Reading from left to right helps to understand the number line

People have been argued to have an internal number line that goes from left to right in most western countries and it is thought that the direction of this number line is influenced by the reading direction in those countries. A recent study showed that when reading The Very Hungry Caterpillar, a children’s book in which the caterpillar comes out of an egg, looks for food, and eats one apple, two pears, three plums, four strawberries, and five oranges, children who read the book with the pictures presented from right to left and page turning from left to right (so opposite of usual books) changed their counting direction from right to left when counting a row of coins. Therefore, the orientation of the pages and pictures in shared book reading activities can activate and change the child’s spatial representation of numbers along a number line (see Göbel and colleagues, 2018)[3].

It has been shown that children who have a firm mental number line are more able to manipulate numbers and as a result have better mathematical abilities. Number lines and narratives share the fact that both have a structure or sequence to them. Therefore, using words such as ‘before’, ‘after’, ‘in front’,’ ‘next’, ‘forward’ and ‘backward’ in stories will help understanding of sequences and of number lines. In addition, books are like number lines in that a book goes from page 1 to the final page just like a number line goes from the start to the finish. As pages are flipped, pages with smaller numbers are placed on the left and pages with larger numbers remain on the right. Therefore, as children get more familiar with books they get a stronger understanding of the relationship between space and numbers.

A study by Daniela O’Neill and colleagues (2004)[4] examined the narratives of 3-year-old children who were asked to tell a story from a wordless picture book. The researchers analysed various aspects of the children’s narratives, including how many conjunctions children used, i.e. sentences that include words such as ‘and’, ‘but’, ‘or’, ‘because’, ‘after’, along with the event content of the stories, i.e. how many different parts the story contained (which shows the richness of the content of the story). The number of conjunctions and events used when children were three years old correlated to their mathematical performance at that age, as well as predicted their mathematical performance two years later. This suggests that there is a relationship between exposure to books, narratives, and number line development and improved number line abilities allow for improved mathematical abilities.

In reality, all books and stories contain some kind of mathematical content, as mathematics is truly embedded within our culture (telling the time, reading the number of a bus/train to catch, postcodes, telephone numbers, cooking etc.). Therefore, it is less about the kind of story or book but rather how they can be used to highlight mathematical concepts.

Teaching mathematical concepts

The best way to teach children mathematical concepts is to first read the story while pointing out pictures and highlighting mathematical concepts and vocabulary words such as ‘same’, ‘different’, ‘bigger’, ‘smaller’, ‘half’, ‘whole’, ‘next’, ‘after’, ‘before’. We often assume that children will implicitly absorb the information we tell or teach them. Although this is true to some extent, it is better to talk to children about the vocabulary words and define them within the context of the story. For example, when reading the story ‘Two of Everything’, a child might not be familiar with the word ‘double’ and thus it may be necessary to explain this explicitly. In order to check that your child has understood the mathematical concept in the story, you could ask your child some other examples of this mathematical concept from the book or even from outside of the book. For example, when reading Goldilocks you can ask, “There were three bowls in the book. Were there any other groups of three in the book?”.

Conclusion

In conclusion, mathematical learning starts at home from birth onwards. Through narratives and shared book reading, children develop an improved mathematical understanding which can influence mathematical abilities later on in life. There are a number of ways in which narratives can help children. First of all narratives can teach children new concepts such as counting, number words, and cardinality. Secondly, books and narratives provide a structure and sequence that may influence children’s mathematical number line visualisation and understanding of how numbers relate to each other. Thirdly, narratives and books facilitate children’s development of a rich mathematical vocabulary. And finally, books and narratives help to engage children and to provide a rich context in which mathematical concepts and ideas can be applied, which allows for deeper mathematics knowledge.

Multisensory Learning

clipart

Our world is noisy and distracting, filled with a multitude of sights and sounds; the television is on while we talk on the phone, there are street sounds as we navigate a map, and people talking to each other as we try to attend to a specific conversation.   To walk into a toy shop is to be overwhelmed with sights, sounds, and even smells. Clearly, children are stimulated and excited by information from multiple sensory modalities.

But what is best for their learning? Research from psychology has shown that adults learn better if they are given information in different sensory modalities at the same time. This fact has been used as the basis for many childhood educational programs in literacy and numeracy. But there has been no systematic investigation into whether children learn better from information presented in different sensory modalities. Or if, in fact, there are individual differences in this ability.  To take advantage of multimodal stimuli a learner has to be able to pay attention to one thing and not another, and to switch attention when required. These sophisticated skills – inhibitory control, selective attention and cognitive flexibility – are developed slowly throughout the course of childhood, and some children develop slower than others. Preliminary results show that, as a consequence, children can struggle to learn from multimodal information.

New CEN Paper

pic_paper

pic_hannahwThe CEN has published a new paper! It presents the pilot study carried out at the start of UnLocke, a multidisciplinary and collaborative research project aiming at better understanding how primary school children learn counterintuitive concepts in maths and science. In this blog Dr. Hannah Wilkinson, postdoctoral researcher at Birkbeck University, summarises the paper and its key implications.

 

Why did you carry out this study?

Many concepts in maths and science are counterintuitive [1]. This is because children hold naïve theories based on their first-hand experiences of the world (e.g. a belief that the world is flat as the ground beneath us appears flat and when a child kicks a ball it behaves as if on a flat surface) or misleading perceptual cues (e.g. a belief that the angles in a large triangle are greater than those in a small triangle, because the overall shape is larger). These ‘misconceptions’ can interfere with learning new concepts, even into adulthood [2].

pic_flat_earth pwp_triangle3

Evidence from cognitive neuroscience suggests that learning counterintuitive concepts requires inhibitory control [3,4]. Inhibitory control is the ability to withhold an intuitive, pre-potent response, in favour of a more considered response – it is one of a set of cognitive control processes or ‘executive functions’ [5]. Therefore, we were interested in finding out whether training children to use their inhibitory control could improve learning of counterintuitive concepts. However, traditional executive function training has shown limited success in terms of participants transferring their skills beyond the trained task [6]. Taking a novel approach, we developed and evaluated a computerised classroom-based intervention, Stop & Think, which embeds inhibitory control training within the specific domain in which we would like children to use it, i.e. content from the maths and science school curricula.

pic_stopthink

What are your key findings?

Cross-sectional analyses of data from 627 children in Years 3 and 5 (7- to 10-year-olds) demonstrated that inhibitory control (measured on a Stroop-like task) was associated with counterintuitive reasoning and maths and science achievement.

In addition, a subsample of 456 children had teaching as usual or participated in Stop & Think (12 minutes, 3 times per week) for 10 weeks. There were no significant intervention effects for Year 5 children. However, for Year 3 children, Stop & Think led to significantly better maths and science counterintuitive reasoning performance and significantly better standardised science achievement scores (but not maths achievement scores) compared to teaching as usual.

Why is it important for educators?

These findings support the idea that inhibitory control contributes to counterintuitive reasoning and mathematics and science achievement. Therefore, ensuring children can effectively use their inhibitory control in the classroom is important for educators.

From an educational neuroscience perspective, these findings provide preliminary evidence that a neurobiologically-informed intervention delivered by teachers in the classroom, can improve ‘real-world’ academic learning.

Furthermore, there have been few interventions that target primary school science despite the subject’s economic importance [7]. Science, Technology, Engineering and Mathematics (STEM) industries contribute over £68 billion a year to the UK economy and account for over a third of UK exports. Despite their importance, there has been little emphasis on interventions that target mathematics and science skills, particularly when compared to the wealth of literature on literacy skills intervention. The promising findings here, in particular for Year 3 science, suggests that there could be educational and economic gains from training such as Stop & Think as an educational tool within primary school lessons.

Inhibition and cognitive load in fractions and decimals

Vana Avgerinou is a classroom assistant at Putney High School. She completed an MSc in Educational Psychology at UCL IoE and is currently studying for an MA in Specific Learning Difficulties (Dyslexia). In this video, she presents her new research paper, investigating the role of inhibitory control in learning counterintuitive fractions and decimals, among primary school children. Her results indicate a more nuanced relation between inhibitory control and counterintuitive fractions and decimals than presumed by previous research. They suggest that the role of inhibitory control when reasoning about counterintuitive fractions and decimals is not constant, and it is only drawn on at high levels of cognitive load.

Psyched! event from the ‘Me, Human’ team on the evolution of language

frog-talkingblog_pic2

‘Lovely cabaret style set-up and relaxed mood. Excellent quality of content.’

For its public engagement event on the origin of human language, the ‘Me, Human’ team chose an intriguing yet straightforward title: ‘Blah Blah Blah’. This leaves some room for interpretation. So, what was it all about?

On stage, Dr. Gillian Forrester, Dr. Natasha Kirkham, and Dr. Simon Green shared some fun facts about the development of human language, both at the scale of evolution (e.g. from chimpanzees to humans), and at the scale of a human life (e.g. from babies to the elderly). Let’s start with an example of our extraordinary language skills… Can you understand this?

The middle-aged lady who was wearing a long red scarf was eating a chocolate ice-cream in front of the shop that was very busy and situated in the main street, because it was Christmas and she liked the squared bubbly vibes of the end-of-the-year celebrations.

Weird and long sentence? Maybe, but it is still plain English. The capacity to generate an infinite number of sentences, expressing various events in the past, present and future, is one of the unique characteristics of human language. Although other species, such as chimpanzees, use vocalisations to share information about specific things, such as food or predators, their language does not seem to have generative properties. Most importantly, their language is not necessarily voluntary: they cannot always inhibit their screams even if there is no one around. Imagine if you were shouting ‘chocolate!’ every time you saw a chocolate bar, even when you are alone in the house…

But since we share 98% of our genes with chimpanzees, we still have a lot in common. Tool use, for example. Chimps can do crazy things such as cracking nuts with stones. Over the course of human history, multiple tools have been used to transform our natural environment (e.g. lighting up a fire), process food and create necessities (e.g. clothes). Fine motor skills, such as the ones used to manipulate tools, actually recruit the same areas of the brain as language. Have you ever found yourself sticking your tongue out as you were trying to put a thread into a needle?  Well, that’s it. As humans evolved to use tools more and more frequently, it became useful to not only use gestures but also oral language to communicate. This way, hands could be kept free for manual work. The development of language skills occurred in parallel with changes in the configuration of the mouth and of the larynx, as well as with the adoption of a bipedal posture.

‘Excellent knowledgeable presenters. Fun vibe, not too heavy.’

One of the disadvantages of being bidpedals is that human hips are relatively narrow – and are brain-body ratio is proportionately larger than other primates. Although the brain is folded like a little nut within the cranium, a baby’s head is still relatively big relative to the size of the cervix. Mothers, you know that… When babies are born, they are still quite early in their development. They are dependent on other people’s help. Babies need eye contact to communicate. Being progressively helped by adults’ scaffolding, they use and understand pointing to share their attention to external objects. They learn to be aware of their facial expressions and to progressively shape their vocalisations in a specific language. Until 6 months of age, babies are not yet ‘tuned it’ to any specific language. Then, they get accustomed to the specific sounds and boundaries of their native language. Learning where words start and end in a given language actually requires quite a lot of expertise. A great deal of statistical learning occurs here – with experience, children compare different sentences and learn that some words and sounds can, or cannot follow each other. ‘This is a pretty baby’. You could understand: ‘this is a prettyba by’, but this is not very frequent, is it? The importance of segmentation is quite obvious when we hear a foreign language. When hearing people speaking another language, does it seem to you to be like an endless sentence, or just a blurry ‘BlahBlahBlah’? Well, that is it.

Furthermore, as if it was not complex enough, language is multisensory. Most of the time, we establish visual contact with the people we talk to. We see their lips and can follow the movements of their mouth to get more cues if we have difficulties to hear what they say. But what happen when the sound we hear and the lips movements are not congruent? We start to hear funny sounds. Try it by yourself. This shows that we integrate both visual and auditory information when we process language.

The ‘Me, Human’ event was the opportunity to be bewitched by the fantastic skills primates and humans have developed throughout history. From the new-born babies who needs vocalisations to express their needs, to the mature adults who are playing with words with a Scrabble, there is a lot to learn, and to share.

So if you have not been to this event but are interested in attending the next one about lust(!), you can book you ticket here. You can follow the team @Me__Human  #MHPsyched.
