New developments in AI are making headline news with many perspectives on what the future of AI holds. From Chat GPT to robots, there is lots of new information to take in! This week Dr. Abhilasha Ravichander answers our questions from the basics of AI to questions of AI and consciousness. She speaks to us about where the field is at now and discusses her research on hallucinations in Large Language Models and how they can help us understand how our data is being used. Ava and Beth talk about where they think the future is going.
How do behavioural and substance addictions relate to mental health? What are the risk factors for these disorders? This week Dr. Andrew Kim helps us answer these questions and discusses how we can best treat addictions and their mental heath co-morbidities.

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. Beth and Ava discuss how to think about the similarities and differences between humans and other great apes.
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. Dr. Bein discusses how we segment our experiences to store as our memories and how these processes might be different for people with anxiety. We also give some tips to improve memory and Ava and Beth reflect on how schemas might influences their perspectives.
When something's bothering you, do you tend to suppress those emotions or sit with them? Dr. Rachel Low joins us to discuss her research on emotion regulation in individuals, relationships, and families. Learn about how parents' emotion regulation styles might spill over to their children, and how just one person suppressing their emotions in a romantic relationship can undermine relationship satisfaction. Beth and Ava talk about their own patterns of emotion regulation.
Is sexual chemistry just natural compatibility, or can it grow from effort and work? Dr. Jessica Maxwell shares her research exploring how sexual beliefs influence well-being in both long-term and casual relationships. We discuss how individual differences, like attachment styles, shape our relationship preferences, from one-night stands to long-term monogamy. Plus, stay tuned for practical tips for maintaining passion in long-term relationships!
How often do you play negative experiences over in your head? If this is a painful pattern of thinking, why would we do this? 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. He also shares work on how pandemics and fear of contagion may make even the unprejudiced support xenophobic policies. Beth and Ava have an honest conversation about their own experiences with social class.
What makes a for a good conversation? Why do we feel we 'click' with some people and not others? This week we speak to Dr. Emma Templeton about research on conversation. She discusses why gap length between two conversation partners is important into understanding our connections and why this may have different meanings between strangers and friends. Ava and Beth share how they feel about conversations with strangers, can your take a guess to who loves conversations with strangers 100% of the time?
Are we really what we eat? Research on the gut microbiome suggests we really are! This week we speak to Dr. Aya Osman who researches how the gut microbiome influences our brain and behaviour. Dr Osman explains the role of the gut microbiome in addiction and autism and how we can study these connections. We learn what foods are best for a healthy gut. Ava and Beth discuss their personal experiences with the gut microbiome with some pretty rogue stories!
One of the biggest mysteries in science is, what is consciousness? This week we speak to Dr Anil Seth about how we can study consciousness and where the field is at the moment. Dr. Seth discusses how our experience can be considered a controlled hallucination and what all this means for AI. Ava and Beth reflect on their views which somehow relates back to Terminator 2.
What happens to our memories as we age? Dr. Tarek Amer challenges the idea that memory decline is inevitable as we get older. Tune in to find out when older adults' 'sticky' memories not only aid in recollection but also enhance creativity, potentially giving them an edge over younger folks.
How do you decide to do your maths homework or play a video game? Why does maths homework feel like more effort than the video game? This week we speak with Dr. Laura Ana Bustamante about how cognitive effort effects the decisions we make. She speaks about her research relating cognitive to physical effort, how we can increase our willingness to exert effort and the relationship between anxiety and cognitive effort. Ava and Beth discuss their own approaches when it comes to effort.
When guilt strikes, how do you respond? Is it a rush to make things right or an urge to evade? Dr. Hongbo Yu is joins us to delve into the complexities of guilt, its neural bases, and the surprising role our eyes play in magnifying or mitigating those guilty feelings. Plus, Beth and Ava share some personal perspectives on eye contact.
Elle Murata is a neuroscience Ph.D. student specializing in the impact of sex hormones on the brain. When she noticed something was off with her own menstrual cycle, she found herself having to advocate for her own health to receive proper care. In this conversation, Elle shares her journey to find answers about her own health, and insights from her lab about the effects of sex hormones on our brain's functions.
