Field Studies Flashcards
Both quantitative and qualitative
- E.g. Valentine and Mesout
- heart rate and questionaires
Strength data
Validity
- In depth
- Show reasons and thoughts
Weakness data
Validity
- Subjectivity
- Bias affects
Standardised procedure
- E.g. Valentine and Mesout
- Dungeon tour with anxiety stimuli
- Questionnaire on state and trait anxiety
- Asked to identify person from line up
Strength standardised procedure
Reliability
- Can be replicated to check for results consistency
Lack of control over EVS
- Yarmey
- Public places where crimes may occur
- Can’t control things such as other people, temperature
Strength no EV control
Ecological validity
- Setting is more representative of where eye witnesses are likely to view crimes
Weakness no EV control
Low internal validity
- May impact DV as confounding variables
- Results aren’t accurate
Manipulate IV measure DV
- E.g. Yarmey
- IV - prepared to identify person or not
- DV - success rate of identification
Strength manipulate IV measure DV
Validity
- Cause and effect relationship can be established
Field studies don’t manipulate IV
Yuille and Cutshall real life shooting
Weakness of field studies
Validity
- No cause and effect
