Ciara Greene, an Associate Professor at University College Dublin, dives into the fascinating world of human memory. Her research reveals that memories aren't perfect records but flexible constructs helping us navigate life. They evolve over time, influenced by emotion and context. Discussing her book, Greene highlights the benefits of forgetting and the dangers of misinformation, especially in legal scenarios. Listeners will gain insights into how memories shape our identities and the ethical implications of memory research.

Memory Expectations
Many memory problems stem from unrealistic expectations, not memory flaws.
Understand memory's limitations instead of expecting it to function like a computer.
insights INSIGHT
Memory's Malleability
Memory isn't fixed; it's malleable and adaptable.
This flexibility allows for updates and revisions, though it can lead to inaccuracies.
insights INSIGHT
Reconstructive Memory
Human memory is reconstructive, not a simple retrieval process.
We actively rebuild memories, incorporating current context and experiences, leading to potential inaccuracies.

Ciara Greene is Associate Professor in the University College Dublin School of Psychology. In this episode we discuss Ciara's book Memory Lane: The Perfectly Imperfect Ways We Remember, co-authored by her colleague Gillian Murphy. The book is all about how human episodic memory works and why it works the way it does. Contrary to our common assumption, a "good memory" isn't necessarily highly accurate - we don't store memories like files in a filing cabinet. Instead our memories evolved to help us function in the world. That means our memories are flexible, constantly changing, and that forgetting can be beneficial, for example.
Regarding how our memories work, we discuss how memories are reconstructed each time we access them, and the role of schemas in organizing our episodic memories within the context of our previous experiences. Because our memories evolved for function and not accuracy, there's a wide range of flexibility in how we process and store memories. We're all susceptible to misinformation, all our memories are affected by our emotional states, and so on. Ciara's research explores many of the ways our memories are shaped by these various conditions, and how we should better understand our own and other's memories.
