Q

What us the latin-square design?

A

The arrangement of conditions so that each condition is only completed once at a time e.g.

16
Q

When is the Latin square design typically used?

A

when there are a few conditions e.g. 4

17
Q

What is randomisation?

A

Presents individual trials in a randomised order to eliminate systematic bias

18
Q

What are demand characteristics?

A

When participants behave in a certain way because they think that’s what the researcher demands from them

19
Q

What are pre-tests?

A

The observation/condition before intervention

20
Q

What are experimental treatments?

A

Different interventions or treatments

21
Q

What are post-tests?

A

The observation or measure after the intervention

22
Q

What are maturation effects?

A

Participant’s behaviour changes over time

23
Q

What are history effects?

A

Something changes about participant’s circumstances that influences the variables

24
Q

What are testing effects?

A

Having tested before May change how participant’s do on the post-tests

25
What is a passive control group?
Participant's do nothing. They Don'T experience the manipulation from pre or post tests
26
What is an active control group?
Participant's do something that they can reasonably assume have an effect but the researcher's assume doesn't
27
What do we mean by waiting-list?
Participant's are waiting to take part in the manipulation/experimental research condition and believe that they will be at some point
28
What is attrition?
When participant's start a study but don't complete it
29
What is matched design?
A research design that matches participant's by certain characteristics: Age, gender, occupation etc
30
What is random group assignment?
Using chance procedures to put participant's In groups randomly giving Them all an equal chance to be assigned to certain groups
