3 surprising ways curiosity changes your brain

You are more engaged, active, and open-minded when you’re curious. But what is it about curiosity that makes it so powerful? In this issue, we explore the psychology of curiosity and three surprising ways it changes your brain.

Curiosity Boosts Memory

In a study published in 2014, researchers discovered a connection between memory and curiosity levels. Here are some of the key findings from the investigation by the University of California at Davis:

  1. When people are curious to learn the answer to a question, they are better at learning that information – not only in the very short term but also after a 24-hour delay.
  2. Most surprising, though, was participants had greater recall of unrelated, extraneous or incidental information present at the time.
  3. Scans revealed when people were more curious, brain activity rose in regions that transmit dopamine signals; in the hippocampus, the part of the brain associated with memory and regions related to reward.

Point number two helps me get a handle on the characteristic of being open-minded. We can remember more of our experiences when we are curious.

A little test you can do for this is to try and remember extraneous information connected to an enjoyable learning experience.

Risk and Reward

When faced with something new, our brain weighs the risks and rewards before deciding whether to engage.

This happens when you are scrolling and decide to open an article or photo. You made a similar micro-calculation when you saw the subject of this email. Is this worth my time?

Curiosity, the restless feeling of wanting to know more, tips the scales in favour of exploration.

The regions deep in your brain responsible for processing rewards and motivation are active when you become curious. The nucleus accumbens, the bilateral caudate nucleus, and the ventral tegmental area all fire up when we want to know more.

When we’re curious, our brain has decided the potential rewards outweigh the risks. And this instinctive risk/reward calculation drives us to explore the physical and mental world around us.

Designing provocations for learning is a great way to heighten curiosity, so your students don’t scroll by!

Curiosity Powers Our Motivation to Learn

When was the last time you discovered something new in a favourite topic? Experiences which challenge our knowledge increase curiosity and cause us to explore for longer.

Here’s a recent example I experienced.

Most of our understanding of effective teaching has shifted since I was a primary teacher. I am curious about this tweet about Adaptive Teaching vs Differentiation, which presents the following statement:

Having lower expectations for some groups, particularly by setting them different work, will result in pupils having different knowledge and worsens gaps.

Challenged? ✅ Curious? ✅ Motivated to find out more? ✅

All new learning challenges the schemas we use to organise knowledge and understanding. A study by researchers Bonawitz, Schijndel, Friel, and Schulz found children are more likely to remain curious in this challenged state.

An unpublished Duke University study also showed heightened curiosity, increased patience and made people more willing to wait to discover a solution. In contrast, less curious people were more impatient and wanted to jump straight to the answers.

More curiosity has the power to motivate us for longer and increase our patience for discovery.

⏭🎯 Your Next Steps

​Commit to action and turn words into works

  • Pay attention to the signals of your own curiosity and the positive impact it has on your learning.
  • Don’t just tell people they need to be open minded. Use provocations and well designed questions to increase curiosity.
  • Change the start of your next few lessons or workshops to optimise for curiosity.

🗣💬 Your Talking Points

​Lead a team dialogue with these provocations

  • Your challenge is to increase curiosity in your team. What do you need from me?
  • What’s the best way to challenge long-held views?
  • When was the last time you changed your mind?

If You’re The 1st Responder To New Ideas, You Have A Critical Job

You get a moment to choose.

Your decision influences the dynamic of talk and wonder, whether you like it or not.

The pocket-sized hidden curriculum encourages or dampens enthusiasm-worse still, it spirals into self-preservation.

Questions litter the learning space in the primary and early years, often strewn around quite randomly.

I was once asked, If a pea had a brain, how big would it be?

Mourn Those Precious Little Sparks

These precious sparks exist momentarily, but the impact of our response to questions has an extended half-life.

Each of us is born with two contradictory sets of instructions: a conservative tendency, made up of instincts for self-preservation, self-aggrandisement, and saving energy, and an expansive tendency made up of instincts for exploring, for enjoying novelty and risk. We need both. But whereas the first tendency requires little encouragement, the second can wilt if it is not cultivated.

Creativity: Flow and the Psychology of Discovery and Invention — Mihaly Csikszentmihalyi

How you react to ideas is comparable. Consider the response when new ideas or contributions are shared in your team. There is a fundamental similarity to this moment of micro-judgement.

I wonder how the tiny moments of judgement or encouragement shape the climate of our teams? My hunch is, over time, they shape our experience in a significant way.

Culture Is Key To Innovation Potential

The Australian software company Atlassian recently published results of a study into the health of teams with evidence from 1,500 team members outside of Atlassian in the US and Australia. They found that 88% of participants are operating in an ‘unhealthy’ environment.

56 percent feel their team is poorly connected on a personal level, and 37 percent feel like they can’t try new things or express themselves fully.

This is the outcome of the block we started to explore, the micro-judgement of new ideas (or questions).

I wonder why 37 percent of participants can’t express themselves fully? The reasons for holding back might be:

  • fear of being penalised unnecessarily
  • perceived lack of impact or influence
  • worries about how their manager will respond
  • fear of not looking like a team player (they don’t want to appear different)

The Hidden Curriculum of Your Teams

I’ve seen this happen many times. A team member shares something new, and others require an immediate response in the group. Someone questions it confidently (because decades of experience tell them it’s not worth exploring), and the others on the team nod (because they’re too afraid to be the first one out). The new idea is squashed.

It takes more courage to applaud someone who shares new ideas than put them down.

What does this do, though, in the long term? If we belittle, shoot down or diminish new ideas or people who present them, the person might learn that it’s not safe to share in this environment.

In our study, members of healthy teams noted feeling a sense of belonging and support for new ideas. This creates an environment of high engagement, which, in turn, serves as a buffer against burnout and fuels even higher performance.

The first responder to questions or new ideas sets the tone.

Your Talking Points

A few weeks ago, I shared the mental model of compounding in issue 237.

Unnecessary negative micro-judgement of new ideas compounds, the result is unhealthy teams — an example of how compounding works even for negative behaviours.

Your challenge is to notice the first responder and reflect on what behaviours and responses are your standard.

Some of the report’s takeaways direct leaders to focus on encouraging ideas and are worth discussing with your colleagues. Let me draw your attention to these below:

  • Carve out time to explore new ideas, both individually and as a team.
  • Make space for calculated risks and incorporate the lessons you learn.
  • Elevate the importance of diverse viewpoints and make space for respectful dissent.

5 Assessment Questions for Better Measures of Success

In this post, I share some guiding assessment questions and provocations about the value system that education is built on.

There is also a 10-page workbook to download to support your reflection and action planning on assessment and the impact you have on students.

The Most Complicated Object in the Universe

My teaching journey started when I was studying psychology. I chose teaching because of formative experiences in 1995 when studying how we think, develop and learn. Learning elements of developmental psychology was a catalyst to my career.

[sharable-quote tweet=”The human brain has 100 billion neurons, each neuron connected to 10,000 other neurons. Sitting on your shoulders is the most complicated object in the known universe. ~ Michio Kaku “]

The brain seemed an incredible mystery we were all attempting to unravel. As you reflect on your assessment practices, keep that complexity in your mind.

The Draw-a-person Assessment

The drawing test was devised in 1926 by Florence Goodenough, a psychologist from the University of Minnesota. It was developed as “a new approach to measuring young children’s intelligence, ” as her paper is titled.

Children have ten minutes to draw a person, and the results are scored according to strict guidelines. Goodenough argued the drawings were a proxy for intellectual development.

I recall conducting the Draw-a-person test with children at a local primary school or nursery. Deciphering the mark-making and the developmental cues was fascinating.

[sharable-quote tweet=”Teaching is at the intersection between an enduring mystery and a social imperative.” template=”dark”]

Stay Curious About Assessment and Learning

My interest in developmental psychology waned after years in the teaching profession. That is strange to write, as you might expect one to multiply the other.

Perhaps the mystery was overwhelming. Or the distractions incumbent to the teaching profession got in the way. Maybe it was the shiny gloss of technology?

Looking back on my teaching, I wish I had stayed curious for longer about the mysteries of how we learn and assessment questions.

First Principles Questions

Nowadays, I am motivated by the provocation and utility of first principles thinking. A mental model I would take back to 1998 and offer to myself.

We can all find great clarity from the fundamental truths and principles of what we might be exploring. To use first principles, ask questions like these:

  • What are the enduring truths about building positive relationships?
  • What are the first principles of a community?

And the central question:

  • What are the fundamental truths about learning?


Making Sense of What Works

The Draw-a-person test is an interesting exhibit in the story of how teaching is changing. Although widely used, it was also critiqued and fell out of favour as a measure of intellectual development.

I put this down to the scale of the mystery of our brain.

It may have fallen out of favour due to what I call the solution shard effect. This effect occurs when we explain part of a grand mystery.

To begin with, we present a possible truth – a solution shard (fragment). It is not the complete answer, and questions may remain. A part of the truth is presented and explored, and challenged.

However, when this fragment is refuted, it impacts the established elements of truth around it. The second-order effect is a ripple of doubt.

How does this relate to education?

The complexity of how we learn and what teaching should look like can be overwhelming. What we thought worked is no longer valid. Practices that were in favour and widely adopted now languish on the pseudo-science scrap heap.

You might reflect on some of these assessment questions

  • How do I distinguish what works for my students?
  • How can I possibly control so many different aspects of the learning experience?
  • The experience with my students is contrary to the research I have read; what does that mean?

[sharable-quote tweet=”If we solve in silos, there is the potential of adding more fragments to decipher, more heuristics to navigate and more contradictory options of what works.” template=”quote”]

In a way, the confusion, uncertainty and part-truths are not surprising. Teaching is at the intersection between an enduring mystery and a social imperative.

Better Assessment and Measures of Success

A further aspect of Florence Goodenough’s work that is relevant today is the need for broader measures of success and better assessment questions. She asked children to draw as a way of expressing their intelligence and development. It wasn’t just a number.

Jonah Lehrer explains in his article about Goodenough’s test:

there are countless ways to measure human intelligence, whatever that is. We’ve settled on a particular concept of intelligence defined by a short list of measurable mental talents. (Modern IQ tests tend to focus on abilities such as mental control, processing speed and quantitative reasoning.) But Goodenough’s tool is proof that the mystery of smarts has no single solution. The IQ test could have been a drawing test.

The Draw-A-Person Test – Jonah Lehrer

What do we value in schools?

Even in the 1920s, Goodenough attempted to develop better assessment questions and methods for understanding young children’s growth and development. Although an enduring mystery, a century later, a growing number of educators, schools and systems are asking, “is there a better way to measure success?”

The challenge of figuring this out at a student and system level is significant. Again, if we solve in silos, there is the potential of adding more fragments to decipher, more heuristics to navigate and more contradictory options of what works.

Trainee Teachers

Imagine for a moment the experience of new trainee teachers. Do we want that experience to be coherent and clear of the swirling mix of ideas? Or is better teaching practice forged from seeking a pathway through the mire?

We need leadership from research organisations, schools and education systems. An example of this is the New Metrics for Success project from Melbourne University.

a collaborative research venture between The University of Melbourne and selected forward-thinking schools to work in partnership to address the meta-problems faced by Australian schools today and in the future.

I wonder what peer projects link to this work from Melbourne University that exists worldwide?

Your Assessment Questions and Talking Points

To support your thinking and dialogue, return to the question of “What are the fundamental truths about learning?”.

Five guiding assessment questions and provocations

Here are five key guiding questions and provocations to frame your next step:

  • What are the fundamental truths about learning that we know work here (in your context)?
  • For this student, what am I doing that is making the biggest difference to their learning growth?
  • What is one truth about learning that I don’t currently do frequently enough?
  • From the strategies I have tried, what are the patterns of impact and change?
  • How can I collaborate on “the truth for us”, the fundamental components of learning design?
