Q

What control was put in place to improve the validity at the start of the study?

A

A hearing test to make sure their hearing didnt impact on the words they recalled

Q

What is a problem with the sample?

A

Shared characteristics as they were all at the APRU which could impact their memory performance

17
Q

What is a strength of the design of this study?

A

It used independent measures so there would be no order effects unfairly effecting one condition making the results more valid

18
Q

Why is the hearing test at the beginning used?

A

To make the results more valid as it elimnates an EV which could effect their performance

19
Q

This study is seen as reliable because

A

Most of the procedure is standardised like everyone having the same timings and distractor tasks

20
Q

This study is seen as low in mundane realism because

A

Lists of acoustically similar words etc are not like real life examples of using memory

21
Q

Why was an interference task included?

A

To ensure the validity of testing LTM as earlier attempts made an error of measuring STM instead

22
Q

What is a weakness of the design used?

A

Pariticipant variables might have effected their recall as different people did different word list conditions
