LSP Research Methods & Psychological Theories — Questions and Answers

Question 1: What is the primary purpose of psychological research?

To entertain people.
To systematically study behavior and mental processes. (Correct answer)
To diagnose diseases.
To prescribe medications.

Correct answer: To systematically study behavior and mental processes.

Psychological research is a scientific endeavor aimed at understanding the complexities of human and animal behavior, thoughts, emotions, and motivations. It employs systematic methods, such as observation, experimentation, and data analysis, to develop theories, test hypotheses, and gain empirical knowledge about psychological phenomena. This systematic approach distinguishes it from casual observation or speculation.

Question 2: Which research design manipulates variables to determine cause and effect?

Correlational design.
Experimental design. (Correct answer)
Descriptive design.
Qualitative design.

Correct answer: Experimental design.

The experimental design is unique in its ability to establish cause-and-effect relationships between variables. This is achieved by systematically manipulating an independent variable (the presumed cause) while controlling other factors, and then measuring the effect on a dependent variable. This controlled manipulation allows researchers to infer causality, unlike correlational or descriptive designs.

Question 3: What is a hypothesis in psychological research?

An unchangeable fact.
A testable prediction. (Correct answer)
A random guess.
An assumption without evidence.

Correct answer: A testable prediction.

A hypothesis is a specific, falsifiable statement that proposes a relationship between variables, derived from a theory or prior observations. It serves as the basis for empirical research, guiding the design of experiments or studies to collect data that will either support or refute the prediction. It is not an unchangeable fact or a random guess, but a reasoned, testable proposition.

Question 4: What is a confounding variable?

The independent variable.
An external factor influencing results. (Correct answer)
The dependent variable.
The control variable.

Correct answer: An external factor influencing results.

A confounding variable is an extraneous factor that correlates with both the independent and dependent variables, potentially distorting the true relationship between them. If not controlled, it can lead to a misinterpretation of results, making it seem as though the independent variable caused an effect when it was actually the confound. Researchers strive to minimize their influence to ensure valid conclusions.

Question 5: Which psychological theory emphasizes learning through reinforcement?

Psychoanalytic theory.
Behaviorism. (Correct answer)
Humanistic theory.
Cognitive theory.

Correct answer: Behaviorism.

Behaviorism, a school of thought pioneered by psychologists like B.F. Skinner, focuses exclusively on observable behaviors and how they are learned through interaction with the environment. Central to this theory is the concept of reinforcement, where behaviors are strengthened or weakened by their consequences, such as rewards or punishments.

Question 6: What is the role of a control group in an experiment?

To receive the experimental treatment.
To act as a baseline for comparison. (Correct answer)
To confuse participants.
To manipulate variables.

Correct answer: To act as a baseline for comparison.

In an experimental design, the control group does not receive the experimental treatment or intervention. Its purpose is to provide a baseline against which the effects of the independent variable on the experimental group can be measured. This comparison allows researchers to determine if the treatment had a significant effect, isolating its impact from other factors.

Question 7: What is informed consent?

Forced participation.
Voluntary agreement after full disclosure. (Correct answer)
Participation without explanation.
Coerced participation.

Correct answer: Voluntary agreement after full disclosure.

Informed consent is a fundamental ethical principle in research, ensuring that participants freely agree to take part in a study after being fully informed about its purpose, procedures, potential risks, and benefits. This process respects individual autonomy and protects participants from coercion or exploitation, allowing them to make an educated decision.

Question 8: What does random assignment do in research?

Introduces bias.
Reduces bias by random distribution. (Correct answer)
Increases bias.
Has no effect on bias.

Correct answer: Reduces bias by random distribution.

Random assignment is a critical technique in experimental research where participants are allocated to different experimental conditions (e.g., treatment or control group) purely by chance. This process helps to ensure that groups are equivalent on all characteristics at the outset, minimizing systematic differences and reducing the likelihood of selection bias, thereby strengthening the internal validity of the study.

Question 9: Which psychological theory focuses on self-actualization?

Behaviorism.
Psychoanalysis.
Humanistic theory. (Correct answer)
Cognitive theory.

Correct answer: Humanistic theory.

Humanistic psychology, with key figures like Abraham Maslow and Carl Rogers, emphasizes the inherent goodness of people and their innate drive towards self-actualization. This theory focuses on individual potential, free will, and the importance of personal growth and fulfillment, contrasting with deterministic views of behaviorism or psychoanalysis.
