A

a procedure that ensures that, at the end of the experiment, the participant leaves understanding the experimental aim, results and conclusions

Explain the concept of Informed consent

A

processes that ensure participants understand the nature and purpose of the experiment, including potential
risks (both physical and psychological), before agreeing to partic

34
Q

Explain the concept of Use of deception in research

A

the act of intentionally misleading participants about the true nature of a study or procedure

Dividing population into distinctive sub-groups, then selecting a separate sample from each sub-group in the same proportions as they occur in the population

Easy to claim the sample is representative of the general population but is time consuming and expensive

A

ADVANTAGES:
Eliminates participant differences
Fewer participants needed

DISADVANTAGES:
Dropouts
Order/boredom/practice effect

54
Q

What are the advantages and disadvantages of between subjects designs

A

ADVANTAGES:
quick and easy
cost effective
few dropouts
DISADVANTAGES:
doesn’t control individual participant differences

55
Q

What is the difference between within and between subject designs

A

In within subjects designs participants complete every experimental condition
In between subjects designs individuals are divided into different groups and complete only one experimental condition
