Yet according to psychologist Gemma Spike, this is exactly what occurs in every human brain, far more often than most people realize.

Show Notes
We treat our memories like a reliable recording of the past. We remember what happened, how we felt, where we were, and what was said. But what if our account is more like a subjective recollection of events? In this episode, we explore the concept of false memories – how they form, why this matters in our everyday lives, and their more serious potential impacts.
We explore:
• The cognitive mechanisms behind false memories
• The misinformation effect and the car crash study
• Why our memories are open to imagination, repetition and social influence
• Potential consequences of false memories in news reporting and eyewitness testimony
• The importance of ethical therapeutic practices and memory
