Test 1: Chapter 1 Flashcards
What is psychology?
Scientific research to understand behaviour and mental processes.
What are the 4 goals of psychology?
- Describe (what behaviour to describe)
- Explain (why the behaviour is happening)
- Predict (likelihood behaviour will occur given variables)
- Influence (control behaviour)
What is scientific theory?
- Proposes reasons for relationships among events and allows us to derive explanations and predictions.
- If our descriptions are not well explained/predicted by our theory we need to modify it.
What is basic research?
It’s acquiring knowledge to understand behaviour (describes, explains, predicts)
What is applied research?
It’s to change behaviour (influence)
What are the research methods?
- Watch - observation
- Ask - survey
- Make a move - experiment
What are the descriptive research methods?
- Observation
- Naturalistic
- Participant
- Laboratory
- Case study
- Psychological tests
What is observation?
To observe and record behaviour without interference.
What is naturalistic observation?
In natural setting.
What are the strengths of naturalistic observation?
- True behaviour
- Natural setting
What are the weaknesses of naturalistic observation?
- Long
- Observer bias
- Privacy
- Consent
What is participant observation?
Join a group/culture in their natural setting (undercover psychologist).
What are the strengths of participant observation?
- True behaviour
- Natural setting
- Can observe for longer period of time (more date)
What are the weaknesses of participant observation?
- Long
- Observer bias
- Privacy
- Consent
What is laboratory observation?
In a lab.
What are the strengths of laboratory observation?
- More control
- Better measurement
- More time efficient
- Consent
What are the weaknesses of laboratory observation?
- Artificial setting
- Participant bias
What is a survey?
Interviews/questionnaires to gather info about attitudes, beliefs, experiences, or behaviours.
What are the strengths of a survey?
- Time and cost efficient (for questionnaires)
- Large sample
What are the weaknesses of a survey?
- Inaccurate data? (Truth? Memory?)
- Wording effects?
- Random sampling?
What is a case study?
A single person or a small group are studied in great depth, over an extended period of time.
What are the strengths of a case study?
- In depth analysis
- Uncommon disorders or experiences
What are the weaknesses of a case study?
- Not generalizable
What are psychological tests?
Tests to measure different aspects of behaviour (physical, cognitive, social/personality).
What is the correlational method?
Relationships between 2 or more variables/behaviours.
What is negative correlation?
As 1 variable increases the other decreases (0 to -1)
What is positive correlation?
2 variables move together (both up/down).
What is the experimental method?
Searching for causes.
What is a hypothesis?
An educated prediction.
What is the independent variable?
Possible cause.
What is the dependent variable?
Behaviour.
What is the confounding variable?
Other causes.
What is population?
The demographic of interest.
What is a sample?
The participants.
