Memory Palace - At the Beach by Trent

Misinformation Effect

Pathway to the beach: A human-sized seahorse is erasing their crab friends' footprints from the path while telling everyone that their friends' footprints were never there. The people are arguing about if a dog or a horse came through.

Meaning: This showcases Elizabeth Loftus's "misinformation effect." This shows how our memories can be tricked by misinformation even after a fact.

Iconic Memory

Towel area at the beach: A person is sitting on their towel and sees a plane fly by at the beach. The plane spells out 18 random letters. These letters go away quickly, and the person can only remember the first six of them.

Meaning: This scenario showcases George Sperling's research on "iconic memory." While many people can see many letters at once, they can possibly only remember a few before they go away.

Magical Number 7

Snack bar: There is a person working at a snack bar, and they are admiring the 7 beautiful ice cream cones that they made. A kid comes up to this person with an ice cream cone in his hand, wanting to give it to the worker as an act of kindness. The snack bar worker smacks the ice cream cone out of the kid's hand and tells him that he can only have 7 of them. The worker's boss approves of this action.

Meaning: George Miller discovered that short-term memory typically holds on to around seven pieces of information. The worker in this scenario smacks the 8th ice cream cone out of the kid's hand because he cannot handle an 8th piece of information.

Self-reference Effect

Mirror in rest area: A person notices a mirror in the bathroom of a building. When they look into the mirror, it says, "Tell me anything; I'll remember everything there is to know about you." Another person walks by and tries to tell the mirror information that is factual, but the mirror doesn't respond. The mirror only responds when the first person is involved.

Meaning: This represents the "self-reference effect." This means that we remember things better when they relate to us. The brain prefers personal connections.

Frontal lobes and hippocampus: explicit memory

Lifeguard tower: A lifeguard with his brain sticking out of his head is sitting in his chair and being interviewed. Every time someone shouts, "I saw a bird," the interviewer writes it down and the lifeguard nods his head in approval.

Meaning: the lifeguard represents the frontal lobes, and the interviewer represents the hippocampus. This scene shows them working together to form explicit memories. This includes facts and personal experiences.

Cerebellum and basal ganglia: implicit memory

Surfboard shop: A person is doing tricks on a surfboard while sleeping. While someone else is tying knots with their eyes closed. These two people are asked by a curious individual how they are doing that, and they respond saying, "I don't know; I am just doing it."

Meaning: This scene represents implicit memory (controlled by the cerebellum and ganglia). These parts help people perform automatic skills. To put it simply, things that just come natural to individuals.

Amygdala: emotion-related memory

Area with sandcastle: This kid is building a sandcastle, and it gets destroyed by a very big wave. The kid starts crying, and then it starts raining down on him. The shell next to him says, "You will never forget this moment."

Meaning: This scene represents the amygdala (emotion-related memory). A strong feeling like the sadness that the kid feels after his sandcastle is destroyed helps the brain remember certain moments in more detail.

Long term potentiation and the neurotransmitter glutamate

Picnic table at the beach: A couple of friends at a picnic table are passing a glutamate ball with each other. As they pass this ball back and forth with each other, their connection becomes stronger.

Meaning: This represents "long term potentiation." This is where passing the neurotransmitter glutamate strengthens the connections in the brain. This process helps memories last longer.
