experiments

Question 1

lab experiments

Answer 1

• IV manipulated by research
• effect on DV then measured
• conducted in environment specially designed for purpose of experiment

Question 2

quasi experiments

Answer 2

• conducted in a lab or field setting
• no manipulation of IV
• IV naturally occurring e.g. age

Question 3

field experiments

Answer 3

• IV manipulated and DV measured
• occurs in a natural setting
• uses standardise instructions to maintain consistency can be applied to a real world setting (ecological validity)

Question 4

lab disadvantages

Answer 4

• artificial setting
• P’s may change their behaviour
• known as demand characteristics

Question 5

lab advantages

Answer 5

• standardised instructions -> all p’s have same experience, easier to repeat, making study more consistent
• high level of control of extraneous variables and confounding variables
• scientific
• can establish cause and effect

Question 6

field advantages

Answer 6

• natural behavior
• represents normal every day world
• P’s may be unaware of study so no demand characteristics

Question 7

field disadvantages

Answer 7

• less control over extraneous variables
• can’t fully establish cause and effect
• issues around consent

Question 8

quasi disadvantages

Answer 8

• only be used if a natural difference occurs
• can’t fully establish cause and effect
• less control
• hard to replicate

Question 9

quasi advantages

Answer 9

• study real world issues
• can be a natural setting
• P’s unlikely to know about study so no demand characteristics
