WGU C180 INTRODUCTION TO PSYCHOLOGY EXAM COMPLETE
QUESTIONS AND 100% VERIFIED ANSWERS (PASS GUARANTEED)
1. Q: What is psychology? ANSWER Psychology is the scientific study of
behavior and mental processes, including how people think, feel, perceive, and
act.
2. Q: What are the four main goals of psychology? ANSWER The four main
goals are to describe, explain, predict, and control/influence behavior.
3. Q: What is empiricism? ANSWER Empiricism is the view that knowledge
comes from experience and observation rather than intuition or reasoning alone.
4. Q: What is the scientific method in psychology? ANSWER A systematic
approach to research involving observation, hypothesis formation, testing
through experiments, data analysis, and drawing conclusions.
5. Q: What is the difference between basic and applied research?
ANSWER Basic research seeks to expand general knowledge and
understanding, while applied research addresses specific practical problems.
6. Q: Who is considered the father of psychology? ANSWER Wilhelm
Wundt, who established the first psychology laboratory in Leipzig, Germany in
1879.
7. Q: What is structuralism? ANSWER An early psychological approach
focused on breaking down mental processes into basic components through
introspection, developed by Edward Titchener.
8. Q: What is functionalism? ANSWER A psychological approach
emphasizing the purposes and adaptive functions of behavior, influenced by
William James and Darwin's evolution theory.
9. Q: What is behaviorism? ANSWER A perspective focusing on observable
behavior rather than internal mental states, pioneered by John Watson and B.F.
Skinner.
10. Q: What is psychoanalysis? ANSWER Sigmund Freud's theory
emphasizing unconscious motives and conflicts as determinants of behavior.
,11. Q: What is humanistic psychology? ANSWER An approach emphasizing
personal growth, self-actualization, and human potential, developed by Carl
Rogers and Abraham Maslow.
12. Q: What is cognitive psychology? ANSWER The study of mental
processes including perception, memory, thinking, and problem-solving.
13. Q: What is the biopsychosocial model? ANSWER An integrated
approach recognizing that biological, psychological, and social factors interact
to influence behavior and mental processes.
14. Q: What is a hypothesis? ANSWER A testable prediction about the
relationship between variables.
15. Q: What is an operational definition? ANSWER A precise description of
how a variable will be measured or manipulated in a study.
16. Q: What is a theory? ANSWER A comprehensive explanation for a set of
observations that organizes and predicts behaviors or events.
17. Q: What is replication in research? ANSWER Repeating a study to
determine if the findings are consistent and reliable.
18. Q: What are the main research methods in psychology? ANSWER
Experiments, correlational studies, case studies, naturalistic observation, and
surveys.
19. Q: What is an independent variable? ANSWER The variable that is
manipulated by the researcher to observe its effect on the dependent variable.
20. Q: What is a dependent variable? ANSWER The variable that is
measured to see if it is affected by changes in the independent variable.
21. Q: What is random assignment? ANSWER Assigning participants to
experimental or control groups by chance to minimize pre-existing differences.
22. Q: What is a placebo? ANSWER An inactive treatment or substance
given to control groups to account for expectation effects.
23. Q: What is a double-blind procedure? ANSWER An experimental
procedure where neither participants nor researchers know which condition
participants are in, reducing bias.
24. Q: What is a correlation coefficient? ANSWER A statistical measure
(ranging from -1 to +1) indicating the strength and direction of a relationship
between two variables.
, 25. Q: What does correlation not imply? ANSWER Correlation does not
imply causation; a relationship between variables doesn't mean one causes the
other.
Module 2: Biological Bases of Behavior (Questions 26-60)
26. Q: What is a neuron? ANSWER A nerve cell; the basic building block of
the nervous system specialized for transmitting information.
27. Q: What are the three main parts of a neuron? ANSWER The cell body
(soma), dendrites, and axon.
28. Q: What is the function of dendrites? ANSWER To receive incoming
signals from other neurons.
29. Q: What is the function of the axon? ANSWER To transmit signals away
from the cell body to other neurons, muscles, or glands.
30. Q: What is the myelin sheath? ANSWER A fatty coating around some
axons that insulates the axon and speeds up neural transmission.
31. Q: What is an action potential? ANSWER A brief electrical charge that
travels down an axon when a neuron fires.
32. Q: What is the all-or-none principle? ANSWER The principle that a
neuron either fires completely or does not fire at all; there is no partial firing.
33. Q: What is a synapse? ANSWER The gap between the axon terminal of
one neuron and the dendrite or cell body of another neuron.
34. Q: What are neurotransmitters? ANSWER Chemical messengers that
travel across synapses to transmit signals between neurons.
35. Q: What is acetylcholine? ANSWER A neurotransmitter involved in
muscle movement, learning, and memory.
36. Q: What is dopamine? ANSWER A neurotransmitter involved in
movement, motivation, reward, and pleasure.
37. Q: What is serotonin? ANSWER A neurotransmitter that affects mood,
hunger, sleep, and arousal.
38. Q: What is GABA (gamma-aminobutyric acid)? ANSWER The main
inhibitory neurotransmitter in the brain that reduces neural activity.
39. Q: What is glutamate? ANSWER The main excitatory neurotransmitter
involved in learning and memory.
