Psych 335-Introduction to Cognition Introduction to Information Processing: Memory Scanning

Memory Scanning- Saul Sternberg Question: How do we scan through items in memory? We might suppose that we compare the item to other items stored in memory Serial vs. Parallel search Self-terminating vs. exhaustive search If Self-Terminating: Fixed-Order vs. Random-Order search

Design: Present a list of items for memorization Then ask a subject a question about that list Example: – 35682? –subject responds: no. Vary the number of items in the list
