Factors Affecting Memory
Factors like attention, taking photos, and event boundaries influence memory. Neuroscientist Charne Rugganoth highlights how contextual factors and emotions impact memory recall, emphasizing the role of the current context in shaping deposited memories.
Memory Formation and Brain Function
The hippocampus plays a crucial role in forming episodic memories, tying together various aspects of the brain's processing functions. Neuroscientific research reveals how Alzheimer's disease's early stages relate to hippocampal deterioration and the challenges in creating new episodic memories.
Prefrontal Cortex's Role in Memory
The prefrontal cortex's involvement in directing attention and facilitating memory could debunk the notion that it only manages short-term memory. Understanding its function can shed light on memory maintenance and how multitasking affects memory recall.
Impact of Photography on Memory
Using smartphone cameras to document experiences can hinder memory retention due to distractions and lack of focus. Selective and mindful photography, along with revisiting captured moments, can enhance memory recall by providing cues for memory retrieval.
Imagination and Memory Link
Memory and imagination intertwine, shaping how individuals perceive and recall past events. The concept of imaginative construction suggests that memories are not mere replays of the past but are constructed with the aid of imagination, affecting one's identity and viewpoint over time.
Do you sometimes walk to another room in your house to get something, but then can’t remember what it was you wanted? Do you sometimes forget about an appointment or struggle to remember someone’s name?
You may have chalked these lapses in memory up to getting older. And age can indeed play a role in the diminishing power of memory. But as my guest will tell us, there are other factors at play as well.
Charan Ranganath is a neuroscientist, a psychologist, and the author of Why We Remember: Unlocking Memory’s Power to Hold on to What Matters. Today on the show, Charan explains how factors like how we direct our attention, take photos, and move through something called “event boundaries” all affect our memory, and how our current context in life impacts which memories we’re able to recall from the past. We also talk about how to reverse engineer these factors to improve your memory.
