What are echoic and iconic memory?
Iconic memory is for visual information (0.5 to 1 second), and echoic memory is for auditory
information (2 to 4 seconds).
How did the Sperling study measure sensory memory?
Participants recalled letters after brief exposure; results showed memory faded within about 1
second.
What is Short-term Memory?
It temporarily holds and processes information with a capacity of about 7 items and a duration of
15-30 seconds.
What is chunking?
Organizing information into groups to enhance memory.
What is the magic number in short-term memory?
The capacity of short-term memory is about 5-9 items.
, How did Peterson and Peterson study short-term memory?
Participants recalled letters after counting backward; memory dropped significantly after 18-20
seconds.
What are attention, rehearsal, encoding, and retrieval?
Attention selects information, encoding sends it to long-term memory, retrieval brings it back,
and rehearsal maintains it.
What is Long-term Memory?
Relatively permanent storage of information with unlimited capacity and lifelong duration.
Who is Clive Wearing?
A man with severe amnesia who retains music skills and emotional memories but cannot form

Better memory for items at the beginning and end of a list.
What is recency?
