a) When new information interferes with the recall of old information
b) When old information interferes with the recall of new information
c) When information is lost due to lack of rehearsal
d) When memory is impaired due to physical damage to the brain

a) Encoding failure
b) Storage failure
c) Retrieval failure
d) All of the above
Answer: d) All of the above
Explanation: Memory failures can occur during encoding (information not properly stored), storage (information lost over time), or retrieval (failure to access stored information).
17. What is the main purpose of rehearsal in memory?
a) To encode information for storage
b) To prevent forgetting by practicing information
c) To decode information into its original form
d) To store information in sensory memory
Answer: b) To prevent forgetting by practicing information
Explanation: Rehearsal involves repeating information to maintain it in short-term memory and transfer it to long-term memory.

b) The tendency to remember items in the middle of a list
c) The tendency to forget items at the beginning of a list
d) The tendency to recall items from a familiar list
Answer: a) The tendency to recall the last items in a list better than the first items
