LSP Research Methods & Psychological Theories

Question 1

What is the primary purpose of psychological research?

Accepted Answer

To systematically study behavior and mental processes.

Answer

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?

Accepted Answer

Experimental design.

Answer

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?

Accepted Answer

A testable prediction.

Answer

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?

Accepted Answer

An external factor influencing results.

Answer

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?

Accepted Answer

Behaviorism.

Answer

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.
