Sensory memory & short-term memory (STM)

Sensory memory holds a lot of info but only for a very short time.

 

Info must be focused on to reach STM. We call this selective attention.

 

Example: Imagine you're at a music concert. There are lots of sounds, lights, and people, but you can focus on the lyrics of the song playing.

Schemas & selective attention

Info going from sensory memory to STM passes through schemas, our mental frameworks. This can distort or filter out info.

 

Example: If you've always thought cats are aloof, you might not notice a friendly cat at a friend's house.

Cognitive biases- asymmetric dominance & framing effect

Asymmetric Dominance

This happens when a third, inferior option (the decoy) makes one of the initial options seem more desirable.

 

Example: You're choosing between two phones, Phone A and Phone B. Then a third phone, Phone C, is introduced, which is worse than Phone B but not Phone A. Even if no one chooses Phone C, its presence makes Phone B more desirable.

 

An experiment by Huber, Payne, and Puto (1982) confirmed this theory.
