What are three types of experiments?
True/lab (one method), field, quasi, natural
100
What are two technological techniques used to study the brain?
MRI and fMRI. (PET, EEG and CT are also acceptable).
100
What are three sampling methods?
Random, opportunity, self-selected, purposive, snowball, (there are others, too)
100
What are three ethical considerations (or guidelines)?
-Informed consent, Right to withdraw, Debriefing, Anonymity, Considerations about deception, Justification (for any possible negative effects), Researcher integrity, Getting approval by a review board


100
What is another term for "external validity?"
Generalizability
200
What is the research method that involves an in-depth investigation of a small group, individual or organization that includes the use of multiple methods to gather and analyze data?
Case study
200
What does an fMRI measure? What does an MRI measure?
MRIs measure brain structure (size, shape, damage, etc.) and fMRIs measure brain activity. 
200

What is the key difference between a self-selected sample and opportunity or random sampling?

Self-selected sampling involves the participant approaching the researchers to ask to participate - the other two involve the researcher approaching participants.

200
True or False? Participants should ALWAYS be given informed consent forms before participating in a study.
False. It might be impossible in field experiments, so where possible they should have debriefing and consent forms AFTER the study.
200
What is generalizability?
The extent to which we can apply our findings to other contexts (e.g. people, places, situations, etc.)
300
What is the general term for the method that investigates the effect of an IV on a DV.
Experiment / Experimental Method
300

What does MRI and fMRI stand for?

Magnetic resonance imaging and functional magnetic resonance imaging.

300
What is the term used to describe the group of people for whom we want to generalize our results to? (Or whom we think we can generalize our results to?)
Target population
300
True or False: Psychologists are allowed to leave out data from studies if it contradicts their hypothesis.
False. All data should be included and fabricated or manipulating results is considered highly unethical since it stands in the way of discovering "truth."
300
What are two types of validity that are relevant to assessing external validity? (Hint: they're to do with environment of the study and the participants involved).
Population validity and ecological validity.
400
True or false: fMRI and MRI are considered research methods in IB Psychology.
False. They are "techniques." DO NOT write about these in any question about research methods.
400

True or false: if a researcher finds some interesting facts about a person's brain through an MRI, they can be published automatically for all to see and be amazed

False. Goes against the right for study participants to remain anonymous

400
What is one strength and one limitation of random sampling?
Strength: increased chances of a representative sample


Limitation: can be difficult, time consuming and impractical

400
True or False: Ethics in the options are completely different considerations to ethics in the core.
False - the same considerations apply in both options and the core, and where possible you should find overlaps.
400
What type of validity is focused on the extent to which the results of the study are because of the manipulation of the independent variable?
Internal validity
500

What is the name of the numerical measure of some type of correlation, meaning a statistical relationship between two variables. 

Correlation coefficient. 
500
How can MRI be used to study localization of brain function?
The MRI identifies damage to the particular area of brain; behaviour can be observed and measured and any changes in behaviour can be attributed to loss of function in a particular part of the brain (therefore, that part of the brain can be concluded to play a role in the behaviour observed - like decision making, memory, fear, etc.)
500

How is a sample labeled when we have a high probability that it accurately represents our target population?

Representative sample

500
What is one way you can "discuss" an ethical consideration?
a) by looking at how following a guideline could affect the validity of results, b) by offering justification for ignoring particular guidelines in some contexts, 
500

What is the simplest way to ensure internal validity in a research design? External validity?

Internal validity: control for EVs

External validity: randomize/large sample/naturalistic scenario
