Experimental Methods

Question 1

Lab experiment:

Answer 1

Well controlled environment.
Accurate measures are possible.
R.A.P.
Demand characteristics may lead to CVs.

Question 2

Lab:
Internal validity
😄

Answer 2

High ➡️ Control of EVs so they don’t become CVs.

R.A.P

Question 3

Lab:
Ecological validity
😔

Answer 3

Low ➡️ Artificial setting - we can not be confident to generalise conclusions to a real life setting.
Narrow focus - only measures a tiny aspect of memory. (We can not be confident…)

Question 4

Lab:

Manipulation??

Answer 4

Yes - IV is manipulated to see the effect on the DV.

Question 5

Natural (Quasi) experiment:

Answer 5

Conducted in the everyday environment of Ps.

Low demand characteristics as Ps don’t know they are being studied.

Question 6

Natural:
Internal validity
😔

Answer 6

No control of PVs (no R.A.P) , little control of SVs - hard to replicate study.
Depends where study is conducted (lab/field)

Question 7

Natural:
Ecological validity
😄

Answer 7

Behaviour of Ps is more likely to reflect real life.

Question 8

Natural:

Manipulation??

Answer 8

No -IV occurs naturally.

Question 9

Field experiment:

Answer 9

Done in the everyday environment of Ps.

Low chance of demand characteristics as Ps don’t know they are being tested. (Convert study).

Question 10

Field:
Internal validity
😔

Answer 10

Less control of EVs and no R.A.P. as its conducted in a real life setting.

Question 11

Field:
Ecological validity
😄

Answer 11

High - Real life setting.

Less control means it’s more like the real world.
