2. Selection pressures resulting in our memory
system were probably related to the need to
recall environment the immediate past.

susceptible to disruptions.
e.g “the doorway effect”

6. Memories are susceptible to distortions, including:
a) sharpening: exaggerating, or embellishing selected
characteristics of a memory
b) leveling: Weakening or downplaying details or
selected characteristics of a memory.
c) confabulation: combining details from many
memories, or making up entirely false memories that
are recalled and experienced as real.
e.g. the “Bugs Bunny effect”
Psychology professor Elizabeth Loftus, “The Bunny Effect” https://youtu.be/eZlPzSeUDDw [1:08]
6. Memory is an "unreliable reporter" when it comes to
recalling past events & experiences.
•
Events never occur exactly the way we remember them.
e.g. 9/11 memories
•
REALITY: "Everything you remember is made up."
