Golden rule |
Always involves a minimum of 2 groups(conditions). Looking for a difference between the conditions |
How many conditions does it involve? |
|
|
Independent and dependent Variable |
Independent: manipulates(controls), creates differences. Dependent: measures- records results. The researchers looking for how the IV has caused the effect on the DV . |
Controls and measure |
|
|
Key features of laboratory |
1) Takes place in a tight controlled artificial enviro. 2)The researcher directly manipulates the IV. 3) The researcher measures the DV 4) An attempt to minimise extraneous variable is made but not always possible 5) standardised procedures where by each participant has the same experiment |
Tight Minimise Standardised measure |

|
Strength and weaknesses of lab experiment. |
Strengths: high in reliability (standardised procedures) High internal validity(controlled environment) Weaknesses: low in ecological validity ( artificial environment) Very high in demand characteristics ( doing what they want them to do) |
Reliability Internal validity Ecological validity High demand characteristics |

Albert Bandura (Bobo doll experiment) |
Studied aggression, watching others influence our behaviour. • children from 3-5 •experiment adult+ child in room in room with toys the adult unexpectedly started beating the doll The child does the same once the adult leaves the room Closest imitation when child observed same sex. |
What was the experiment showing? |
|
|
What does extraneous mean? |
A variable other than the IV that could be causing the change in the DV. |
Try to get rid of them to make it an accurate test. e.g. keep intelligence same |
