Grant Et At Methodlogical Issues

Question 1

Data collected

Answer 1

Quantitative - easy to summarise and compare between conditions
The test scores were out of 10 and 16 - the context dependent effect was easy to see in the matching conditions

Question 2

Informed consent

Answer 2

Gained as they were told what task they had to do

Question 3

Deception

Answer 3

They were deceived until after the study when they were debriefed

Question 4

Right to withdraw

Answer 4

They were told it was voluntary

Question 5

Internal validity

Answer 5

High as highly controlled lab experiment with controls, procedure was standardised. There were controls to ensure there were no EV’s (order in which they took the test) however participant variables could have affected the results

Question 6

Ecological validity

Answer 6

reading a article and answering questions on it is an ecologically valid task. However the task was conducted as part of a study not part of the lesson and ppts had to wear headphones to listen to artificial background noise which lowers validity. Also, revision is learnt more than a few mins ago so it doesn’t represent exam conditions

Question 7

Population validity

Answer 7

Low as sample was biased using an opportunity sample which means findings can’t be generalised

Question 8

Can it be repeated?

Answer 8

Yes as highly controlled lab experiment which means it can be repeated to find out reliability

Question 9

What sampling method was used?

Answer 9

Opportunity sample as the 5 ppl recruited people to take part - convenient for researcher as cost and time effective. However, sample might be biased

Question 10

Research method - experiment and design used

Answer 10

Laboratory experiment - controlled and easily replicated
Independent measures design - May be participant variables including interest in the study, ability to focus, but there weren’t any order effects
