Human Factors Methods Flashcards
1
Q
Naturalistic observation
A
- check in with subjects
- involve participants
- multiple realities (study as a whole to determine trends)
2
Q
Ethical issues
A
- beneficence (protection from harm)
- justice in selection of subjects
- providing clear instructions
3
Q
Dependent variables (experimental)
A
- sensitivity
- reaction time
- error rate
- physiological
- EEG
4
Q
Consideration with subjects
A
- representative of target population (or general population)
- randomization
- allow time to rest (fatigue)
- intrusiveness
- experience (test round)
- learning
5
Q
Improve reliability
A
- replication
- randomization of subjects and conditions
6
Q
Improve validity
A
- inter-rater reliability
7
Q
3 elements of situational awareness
A
- ability to perceive each element in situation
- ability to evaluate and understand the information on a more global level
- ability to project the understanding of the situation into the future
8

11
Q
Validity issues for VPA
A

- use alternative methods that are easier to explain
12
Q
2 ways to increase validity for VPA
A
- modeling
- ask them clarifying questions
13
Q
Observation studies
A

- field studies
14
Q
Validity issues for CDM
A
- researcher might bias
- based on memory
15
Q
Validity issues for field studies
A
