Explanation - Case studies focus on in-depth analysis of a single individual to understand unique patterns of brain-behavior relationships.
Correct answer is: Case Study
Q.12 Which method is ideal for studying rare neurological conditions?
Experimental Method
Case Study
Correlational Study
Naturalistic Observation
Explanation - Case studies are useful for rare conditions because they allow detailed examination of uncommon brain disorders.
Correct answer is: Case Study
Q.13 Which type of research method examines relationships between variables without manipulation?
Experimental Method
Correlational Method
Case Study
Longitudinal Study
Explanation - Correlational studies identify relationships or associations between variables but cannot determine causation.
Correct answer is: Correlational Method
Q.14 What is the main ethical concern when conducting neuropsychological research?
Sample size
Informed consent
Data analysis
Equipment cost
Explanation - Ethical research requires participants to understand the study and voluntarily agree to participate, especially when brain procedures are involved.
Correct answer is: Informed consent
Q.15 The term 'neuroimaging' refers to:
Recording electrical signals from the brain
Visualizing the structure or function of the brain
Studying behavior through observation
Measuring cognitive test scores
Explanation - Neuroimaging techniques, such as MRI, fMRI, PET, and CT, allow researchers to see the brain's structure and activity.
Correct answer is: Visualizing the structure or function of the brain
Q.16 Which statistical measure indicates the strength and direction of a relationship between two variables?
Mean
Correlation coefficient
Standard deviation
t-test
Explanation - The correlation coefficient quantifies the degree to which two variables are related, ranging from -1 to +1.
Correct answer is: Correlation coefficient
Q.17 What is the main advantage of using control groups in neuropsychological experiments?
They reduce participant variability
They allow manipulation of variables
They provide baseline for comparison
They simplify data collection
Explanation - Control groups help determine whether the experimental manipulation produces the observed effect by providing a baseline.
Correct answer is: They provide baseline for comparison
Q.18 Which research design follows participants over multiple points to observe changes?
Cross-sectional
Longitudinal
Case Study
Experimental
Explanation - Longitudinal designs track the same individuals over time to study development, aging, or progression of neurological conditions.
Correct answer is: Longitudinal

Correct answer is: Correlational Study
Q.21 Which neuroimaging technique provides high temporal resolution but low spatial resolution?
fMRI
EEG
PET scan
CT scan
Explanation - EEG captures rapid changes in brain activity over milliseconds but cannot precisely locate the source of activity.
Correct answer is: EEG
Q.22 The process of assigning participants to groups randomly helps to:
