Coding

Question 1

What is coding?

Answer 1

In what form information is stored depends on the memory store. The process of converting information into different forms is ‘coding’.

Question 2

How many sensory memory stores does the sensory register contain?

Answer 2

five, one for each sense.

Question 3

Give three examples of sensory memory stores.

Answer 3

1.) touch = tactile memory
2.) sound = echoic memory
3.) visual = iconic memory

Question 4

What were the four groups in Baddeley’s study?

Answer 4

• Group 1 = acoustically similar words
• Group 2 = acoustically dissimilar words
• Group 3 = semantically similar words
• Group 4 = semantically dissimilar words

Question 5

Which group performed worse when immediately asked to recall words in Baddeley’s study?

Answer 5

participants performed worse with acoustically similar words (group 1).

Question 6

How does Baddeley’s research suggest that STM is coded?

Answer 6

through sound/acoustically, because it is better when it can differentiate.

Question 7

Which group performed worse when asked to recall words after 20 minutes in Baddeley’s study?

Answer 7

participants performed worse with semantically similar words (group 3).

Question 8

How does Baddeley’s research suggest that LTM is coded?

Answer 8

through meaning/semantically, because it is better when it can differentiate.

Question 9

What were the strengths of Baddeley’s research?

Answer 9

• controlled lab environment.
• establishes cause and effect.
• lower risk of demand characteristics.
• less/no order effects.

Question 10

What were the weaknesses of Baddeley’s research?

Answer 10

• low ecological validity.
• participant variables.
• difficult and time consuming to find 4 groups of participants.
