Methodology in the study of the Brain

Which of the following is not a characteristic of a case study?

• a. They are often holistic, not focusing only on a single variable

• b. They are often longitudinal

• c. They can be replicated in order to establish reliability

• d. They often use method triangulation to increase credibility

Which of the following is an example of triangulation?

• a. Asking a participant to come to three different interviews

• b. Repeating a study in order to establish reliability

• C. Carrying out a study over months and carrying out several observations.

• D. Having more than one researcher observe an individual and gather data

To what extent is it possible to generalize from a single case study?

• a. You cannot generalize from a single case study.

• b. If they are biological, you can always generalize from a single case study.

• c. A single case study can be generalized only if it is confirmed through animal research.

• d. A single case study must be compared to other similar case studies to identify a trend.

Which of the following is not a conclusion that we can draw from the HM study?

• A. Memory is stored in the hippocampus.

• B. Different types of memory may be transferred to long-term memory differently.

• C. The hippocampus plays a role in retrieving information from long-term memory.

• D. The hippocampus plays a role in transferring information from short-term to long-term memory.

Which brain imaging technique could be considered invasive?

• A. PET scans

• B. MRI scans

• C. CT scans

• D. fMRI scans

Which of the following is true about the use of brain imaging techniques in the study of the brain?

• A. The scanner is a natural environment, so the results have high ecological validity.

• B. An fMRI or MRI cannot be replicated, so these studies are not highly reliable.

• C. The emotional state of an individual being scanned can interfere with the quality of the data collected.

• D. The colors help researchers to understand exactly what is happening in the brain.

What is a key difference between an MRI and an fMRI?

• A. MRIs are more claustrophobic than fMRIs.

• B. MRIs show the structure of the brain; fMRIs show the functioning brain.

• C. MRIs show coloured images of the brain; the fMRI is green and black.

• D. MRIs are invasive; fMRIs are not
