Psychology | Portage Learning | Q & A | 2026 Edition
1. Which of the following best defines psychology?
A) The study of the brain and its chemical functions
B) The scientific study of behavior and mental processes
C) The study of the unconscious and personality
D) The study of abnormality and its treatment
Correct Answer: The scientific study of behavior and mental processes
Rationale: Psychology is formally defined as the scientific study of behavior (observable actions) and
mental processes (internal experiences such as thoughts, feelings, and memories). This definition is the
standard, comprehensive description of the field.
2. In Pavlov's original experiment, the meat powder was the:
A) Unconditioned stimulus (US)
B) Unconditioned response (UR)
C) Conditioned stimulus (CS)
D) Conditioned response (CR)
Correct Answer: Unconditioned stimulus (US)
Rationale: In classical conditioning, the unconditioned stimulus (US) is a stimulus that naturally and
automatically triggers a response without any prior learning. The meat powder naturally caused the dog
to salivate, making it the US.
3. In Pavlov's experiment, the salivation in response to the meat powder was the:
A) Unconditioned stimulus (US)
B) Unconditioned response (UR)
,C) Conditioned stimulus (CS)
D) Conditioned response (CR)
Correct Answer: Unconditioned response (UR)
Rationale: The unconditioned response (UR) is the unlearned, natural response that occurs
automatically to the unconditioned stimulus. The dog's salivation in response to the meat powder is the
UR.
4. In Pavlov's experiment, the bell became the:
A) Unconditioned stimulus (US)
B) Unconditioned response (UR)
C) Conditioned stimulus (CS)
D) Conditioned response (CR)
Correct Answer: Conditioned stimulus (CS)
Rationale: A conditioned stimulus (CS) is a previously neutral stimulus that, after being paired with an
unconditioned stimulus, comes to trigger a conditioned response. The bell, initially neutral, became the
CS after being paired with the meat powder.
5. In Pavlov's experiment, the salivation in response to the bell was the:
A) Unconditioned stimulus (US)
B) Unconditioned response (UR)
C) Conditioned stimulus (CS)
D) Conditioned response (CR)
Correct Answer: Conditioned response (CR)
, Rationale: The conditioned response (CR) is the learned response to a previously neutral stimulus. After
conditioning, the dog salivated (CR) in response to the bell (CS).
6. The initial stage of learning in classical conditioning, during which the neutral stimulus is repeatedly
paired with the unconditioned stimulus, is called:
A) Extinction
B) Spontaneous recovery
C) Acquisition
D) Generalization
Correct Answer: Acquisition
Rationale: Acquisition is the initial stage of learning in classical conditioning. It is the process by which
the neutral stimulus (e.g., the bell) becomes the conditioned stimulus through repeated pairings with
the unconditioned stimulus (e.g., the meat powder).
7. The weakening and eventual disappearance of a learned response in classical conditioning is known
as:
A) Extinction
B) Spontaneous recovery
C) Generalization
D) Discrimination
Correct Answer: Extinction
Rationale: Extinction occurs when the conditioned stimulus (CS) is presented repeatedly without the
unconditioned stimulus (US). This leads to the weakening and eventual disappearance of the
conditioned response (CR).
8. The reappearance of an extinguished conditioned response after a period of rest is called:
A) Extinction
