Why do students remember
better than Ebbinghaus?

Proactive Interference.





Things you memorized before, interfere with
recent memory
What if you had been memorizing lists and lists of
nonsense words?
Would it affect your ability to remember a new
list?
The first time you park in a large parking lot it is
easy to remember where your car is.
What if you park there every day?
Retroactive interference

New things you have learned interfere
with memory of old items.

Learning new phone numbers at college,
can interfere with the phone numbers you
remember from home.
The sensory store

A very brief storage of sensory
information.
