How are our moral decisions influenced by factors we’re not aware of? A phenomenon known as Moral Licensing claims that when we do something good, we often subconsciously allow ourselves to then do something bad. In this episode, I take a look at whether those who donate money to charity become more likely to let a kid take the blame for a crime they know they committed.
Memory is the glue that binds our mental lives. Without it, we’d be prisoners of the present, unable to use the lessons of the past to change our future. From our first kiss to where we put our keys, memory represents who we are and how we learn and navigate the world. But how does it work? Neuroscientists using cutting-edge techniques are exploring the precise molecular mechanisms of memory. By studying a range of individuals ranging—from an 11-year-old whiz-kid who remembers every detail of his life to a woman who had memories implanted—scientists have uncovered a provocative idea. For much of human history, memory has been seen as a tape recorder that faithfully registers information and replays intact. But now, researchers are discovering that memory is far more malleable, always being written and rewritten, not just by us but by others. We are discovering the precise mechanisms that can explain and even control our memories. The question is—are we ready?
A plush country house is fixed with surveillance cameras while a group of unwitting test subjects are first exposed to youthful memories to test if it can improve their health. Dr Mosley takes them on this nostalgia trip with the help of neuroscientist Dr Jack Lewis and psychologist Anna Machin to determine how reliable memories really are.
Technology isn’t just changing our lives. It’s literally changing our brains -- and maybe for the better. In this episode, I’m a human lab rat in a groundbreaking study at UC Irvine, where scientists test how playing 3D video games affects my spatial memory. Will 10 days of gaming improve my ability to physically navigate a giant, 60-foot maze? And will an fMRI machine detect any physical changes to my brain?
Horizon uncovers the truth about how you really make decisions. Every day you make thousands of decisions, big and small, and behind all them is a powerful battle in your mind, pitting intuition against logic. This conflict affects every aspect of your life - from what you eat to what you believe, and especially to how you spend your money. And it turns out that the intuitive part of your mind is a lot more powerful than you may realise.
