What makes teenagers so keen to embrace risk? Are they chasing potential rewards, or are they just blind to potential consequences? Dr. Nina Lauharatanahirun joins us to discuss the computational and neurobiological underpinnings of risky decision-making in teens. Beth and Ava reminisce about their own adolescence.NOTE: Dr. Lauharatanahirun is recruiting PhD students for the 2024-2025 cycle with a background in neuroscience, psychology, computer science or engineering!

We hear about neuromodulators like serotonin all the time, but how do they actually work? This week Dr. Claire O’Callaghan gives us an introduction to the science of neurobiology! She discusses the roles of serotonin and noradrenaline and we learn that the systems are more complex than we may hear in popular science. Ava and Beth discuss their misconceptions around neuromodulators and Beth shares a personal noradrenaline story!

Are all inequalities perceived the same? Dr. Riana Brown joins us to discuss how different inequalities — health, economic, and belonging — differentially motivate support for collective action and social change. Dr. Brown also shares research on when and why some people might opt to tackle the root causes of inequality, such as advocating for policy changes, versus addressing its immediate consequences, like volunteering at a soup kitchen. Beth and Ava reflect on their personal experiences of participating in social change efforts.

What do the social lives of chimps and bonobos reveal about human cognition? Join us as biological anthropologist & comparative psychologist Dr. Laura Lewis tells us about the social structures of our closest living relatives & shares her research on how chimps and bonobos remember friends and foes and manage their social attention.

How do we store information in the brain? How do we know when one memory should end and another begin? We speak to Dr. Oded Bein who explains how we use schemas to organise information.

This week we talk about rumination with Dr. Rachel Bedder, she explains why we ruminate and how it is different from worry. Dr. Bedder discusses her computational model of rumination and we learn how we can apply these models in real life. Ava and Beth reflect on their own thought patterns.

How does culture shape our actions towards the environment and our responses to global crises? Dr. Kimmon Eom joins us to discuss how different cultures and socioeconomic statuses influence the willingness to engage in pro-environmental actions.
