#10
Which of the following is a potential disadvantage of longitudinal research designs?
They are time-consuming and costly
They do not allow for the study of developmental changes
They are prone to participant dropout
They cannot establish causality
#11
What is the term for the phenomenon where participants' behavior is altered simply because they are being observed?
Hawthorne effect
Confirmation bias
Demand characteristics
Placebo effect
#12
What is the purpose of a debriefing session in psychological research involving deception?

#13
Which of the following is a potential limitation of case study research?
Difficulty in establishing causality
Lack of generalizability to broader populations
Inability to gather in-depth information
Low external validity
#14
In an experiment, what is the difference between the dependent and independent variables?
The dependent variable is manipulated by the researcher, while the independent variable is measured
The dependent variable is measured, while the independent variable is manipulated by the researcher
The dependent variable changes in response to changes in the independent variable
The independent variable is controlled for, while the dependent variable is not
#15
What is the purpose of a placebo in experimental research?
To minimize the effects of demand characteristics
To provide a baseline for comparison
To ensure ethical treatment of participants
To simulate the experimental treatment without its active ingredients
#16
Which of the following is a potential limitation of experimental research designs?
Limited control over variables
Difficulty in establishing causality
Inability to generalize findings to broader populations
Lack of ecological validity
#17
What is the primary difference between quantitative and qualitative research methods?
Quantitative methods focus on numerical data, while qualitative methods focus on exploring meanings and experiences
Quantitative methods are more suitable for naturalistic observation, while qualitative methods involve experimental manipulation
Quantitative methods rely on descriptive statistics, while qualitative methods use inferential statistics
Quantitative methods prioritize hypothesis testing, while qualitative methods prioritize theory building
#18
Which of the following is a characteristic of a quasi-experimental research design?

Control over extraneous variables
Use of experimental manipulation
Lack of random assignment to groups
#19
What is the purpose of a correlation coefficient in statistical analysis?
To determine cause-and-effect relationships

#23
What is the term for the phenomenon where participants may change their behavior or responses based on their perception of what the researcher expects?
Observer bias
Demand characteristics
Placebo effect
Confirmation bias
#24
Which of the following is NOT an ethical consideration in conducting psychological research?
