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

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 volunter 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

What is the difference between an independent and a dependent variable?

In general, the independent variable is the variable that is manipulated and is thought of as the "cause." The dependent variable is the variable that is being measured (often the "effect").

Realistic Group Conflict Theory

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

What is matched pairs design?

When participants are matched on some relevant criteria (e.g. age, gender, occupation) and allocated to different conditions

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
What are two fMRI studies that show the effect of biological variables on brain activity?
Passamonti et al; Radke et al; Goetze et al; Meyer-Lindenberg et al; (There are lots of other acceptable answers - check with your teacher, too)

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

What does the term "reconstructive memory" related to?

It refers to the fact that we consciously have to reconstruct our memories of past events, making them susceptible to manipulation and the inclusion of false information.

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
What is it called when we have a high probability that our sample accurately represents our target population?
Representative sampling
500
What is order effect?

when the order of the task participants are asked to do in a repeated measures experiment may influence the results
