The failure to notice drastic changes in the environment is?
Change Blindness
T/F: We are able to perform multiple tasks simultaneously
False
What is Broadbent’s early selection theory?
stimulants are filtered or selected to be attended to, at an early stage during processing
T/F: Only a limited amount of information can be processed at a time

T/F: In the shadow task by Cherry, people were able to notice the change in language in the unattended ear.
False
What is the limitation of Early Selection Theory?
Cocktail party phenomenon: highly relevant information is processed even if not attended to
What is the Late selection/Attenuation Thoery?
ALL incoming messages receive some low-level meaning analysis
When the unattended messages yield no useful or important information, they are ___________.
