1. Which of the following are essential ethical guidelines established by the American
Psychological Association (APA) for conducting research with human participants? (Select All
That Apply)
A. Informed Consent
B. Deception must never be used under any circumstances
C. Protection from harm and discomfort
D. Confidentiality of participant data
E. Debriefing participants after the study
F. Payment must be provided to all participants regardless of study length
Correct Answer: ACDE
Rationale: Ethical research requires informed consent where participants are told enough
to choose whether they wish to participate. While deception is sometimes used, it must be
justified and followed by a thorough debriefing. Protecting participants from physical or
psychological harm and maintaining their privacy through confidentiality are also core
mandates of the APA ethics code.
,2. Wilhelm Wundt is often referred to as the ‘father of psychology’ because he:
A. Published the first textbook on social psychology
B. Developed the theory of psychoanalysis
C. Was the first to use the term ‘behaviorism’
D. Established the first psychology laboratory in 1879
Correct Answer: D
Rationale: Wilhelm Wundt opened the Institute for Experimental Psychology at the
University of Leipzig in Germany. This event is considered the formal beginning of
psychology as a scientific discipline separate from philosophy and physiology. He used a
method called introspection to study the conscious experience of his subjects.
3. In an experiment designed to study the effects of caffeine on exam performance, the
caffeine dosage is considered the:
A. Dependent variable
B. Independent variable
C. Control variable
D. Confounding variable
Correct Answer: B
Rationale: The independent variable is the factor that is manipulated by the researcher to
see its effect on another variable. In this scenario, the researcher changes the amount of
, caffeine given to participants to observe changes in performance. The exam performance
itself would be the dependent variable because it depends on the manipulation.
4. The branch-like fibers of a neuron that receive incoming messages from other neurons are
called:
A. Axons
B. Myelin sheaths
C. Terminal buttons
D. Dendrites
Correct Answer: D
Rationale: Dendrites are the structures on a neuron that look like tree branches and are
specialized to receive chemical signals. Once these signals are received, they are passed
along to the cell body (soma). The electrical impulse then travels down the axon to reach
the next neuron in the chain.
5. Which of the following are primary functions or characteristics of the Sympathetic Nervous
System? (Select All That Apply)
A. Increased heart rate
B. Stimulation of digestion
C. Dilation of pupils
