Coding, Capacity, Duration

What did Jacobs (1987) investigate in his study on digit span?

• The capacity of long-term memory

• The duration of short-term memory

• The capacity of short-term memory

• The coding of short-term memory

What was the average digit span found by Jacobs (1987)?

• 7.3 for letters, 9.3 for digits

• 5.5 for digits, 6.5 for letters

• 9.3 for letters, 7.3 for digits

• 5.9 for letters, 4.9 for digits

Why are digits recalled more accurately than letters in Jacobs’ study?

• Digits are more meaningful than letters.

• There are fewer digits than letters, making them easier to recall.

• Digits are stored in the long-term memory.

• The participants were trained on numbers before the study.

What was the main finding of Miller’s (1956) study on chunking?

• The capacity of short-term memory is 5 ± 2 items.

• The capacity of short-term memory is 7 ± 2 items.

• Chunking reduces the duration of short-term memory.

• Chunking improves the coding of information.

What is chunking?

• Grouping letters into words to improve coding

• A method of linking new memories to old ones

• Grouping information into meaningful units

• Breaking long-term memories into smaller pieces

What did Peterson and Peterson (1959) investigate?

• The duration of long-term memory

• The coding of short-term memory

• The capacity of short-term memory

• The duration of short-term memory

What technique did Peterson and Peterson use to prevent rehearsal in their study?

• Counting backwards in threes

• Reciting random letters

• Listening to a distracting tone

• Performing a second memory task

According to Peterson and Peterson (1959), how long does information last in STM without rehearsal?

• 3-5 seconds

• 6-12 seconds

• 18-30 seconds

• 1-2 minutes

What was the aim of Bahrick et al. (1975)?

• To investigate the duration of long-term memory

• To examine the coding of long-term memory

• To study the capacity of short-term memory

• To test the effects of rehearsal on STM

In Bahrick et al.’s study, what material was used to test participants’ memory?

• A list of words

• Photographs of familiar places

• High school yearbook photos and names

• Famous quotes
