PSY 164 Lecture Notes - Lecture 4: Simon Effect, Psy
Document Summary
Picking certain stimuli in the environment to pay attention to. Not paying attention to everything all the time. Listening to 2 streams at the same time one stream for each ear. Main instruction: shadowing (repeat what"s in your left ear). Brain decides to say things that make sense, even if that"s not what it"s supposed to be filtering. Attenuator modulates signal makes some stimuli more obvious, some less obvious. In attenuator, a and b get special treatment but c and d do not. Ex: at an airport waiting for your flight to be called, anything that sounds like the crackling of a psa will grab your attention; things that don"t sound like the psa get dampened. Ex: cocktail party effect hearing your name in a conversation across the room at a party sparks your interest. Dictionary unit uses prior knowledge to judge how important stimulus is. Attenuator and dictionary unit combined = shadowing.
