PSYCH 111: Introduction to Psychology: Week 9: Chapter 6 Quizzes: Learning

Correct Answer:

B. A neutral stimulus becomes associated with an unconditioned stimulus, producing a conditioned response

Explanation:

Classical conditioning, discovered by Ivan Pavlov, occurs when a previously neutral stimulus (like a bell) is repeatedly paired with an unconditioned stimulus (such as food) that naturally triggers an unconditioned response (salivation). Over time, the neutral stimulus alone elicits the same response, now called a conditioned response. This process explains how organisms form associations between stimuli and develop new learned responses.

Why Other Options Are Wrong:

A. Learning happens when behaviors are shaped by their consequences, such as rewards or punishments

This describes operant conditioning, not classical conditioning.

C. Learning occurs by watching and imitating the actions of others in the environment

This is observational learning, not Pavlovian conditioning.

D. A reflexive response is suppressed through repeated exposure to the same stimulus

This reflects habituation, a form of non-associative learning, not classical conditioning.

Correct Answer:

B. Learning by watching others and then imitating their actions or behaviors

Explanation:

Observational learning, central to Albert Bandura’s social learning theory, occurs when individuals acquire new behaviors by watching others perform them and then imitating those actions. Unlike classical or operant conditioning, it does not require direct reinforcement or punishment for the learner. Instead, people can learn vicariously by seeing the outcomes of others’ behaviors. This process is essential for cultural transmission, socialization, and skill development.

Why Other Options Are Wrong:

A. Learning by forming associations between two stimuli presented together

This describes classical conditioning, not observational learning.

C. Learning through trial-and-error with reinforcement or punishment

This is operant conditioning, not imitation-based learning.

D. Learning by reducing responsiveness to repeated exposure to a stimulus

This is habituation, a form of non-associative learning, not observational learning.

Correct Answer:

B. Attention, retention, reproduction, motivation

Explanation:

Bandura identified four key steps necessary for observational learning to occur. First is attention, where the learner must focus on the model’s behavior. Next is retention, the ability to remember what was observed. The third step is reproduction, where the learner demonstrates the behavior. Finally, motivation determines whether the learner chooses to perform the behavior, often influenced by vicarious reinforcement or punishment. Together, these steps explain how modeling leads to lasting learning.

Why Other Options Are Wrong:

A. Motivation, retention, attention, reproduction

This sequence is incorrect because attention must come first for learning to occur. Without focus, no other steps can follow.

C. Retention, motivation, attention, reproduction

This order is inaccurate. Motivation occurs last, after the learner has paid attention, retained the information, and can reproduce the behavior.

D. Attention, reproduction, motivation, retention

This skips the crucial step of retention before reproduction. One cannot reproduce a behavior without first remembering it.

Correct Answer:

D. Classical conditioning

Explanation:

In classical conditioning, first described by Ivan Pavlov, a stimulus is presented before a behavior and becomes associated with it. For example, a bell (neutral stimulus) is rung before food (unconditioned stimulus), and over time the bell alone elicits salivation (conditioned response). The key element is that the stimulus precedes the behavior, shaping an automatic response through learned associations.

Why Other Options Are Wrong:

A. Associative learning

This is a broader term that includes both classical and operant conditioning. It is not specific enough to describe the process of stimulus occurring before behavior.

B. Observational learning

This occurs by watching and imitating others’ behaviors. It does not involve pairing a stimulus with a response.

C. Operant conditioning

In operant conditioning, reinforcement or punishment follows the behavior, influencing whether it will be repeated. The behavior occurs before the consequence, not after the stimulus.

Correct Answer:

B. Rats form cognitive maps of mazes even without immediate reinforcement

Explanation:

Edward C. Tolman demonstrated through his maze experiments that rats developed mental representations, or “cognitive maps,” of their environments. Even without immediate reinforcement, they were able to later use this knowledge when rewards were introduced. This finding contradicted strict behaviorists like Watson and Skinner, who argued that reinforcement had to be immediate for learning to occur. Tolman’s work introduced the idea that cognitive processes—such as expectation and mental mapping—play a crucial role in learning.

Why Other Options Are Wrong:

A. Rats in a maze only learn when they receive immediate food rewards

This aligns with Skinner’s radical behaviorism, not Tolman’s findings. Tolman showed rats could learn without immediate reinforcement.

C. Behavior can only be explained by reinforcement schedules and not by cognition

This reflects strict behaviorism, not Tolman’s perspective. Tolman argued cognition is essential in explaining learning.

D. Learning occurs only when reinforcement is paired with a specific behavior

This statement reflects classical or operant conditioning principles but does not account for Tolman’s discovery of latent learning and cognitive mapping.

Correct Answer:

B. Reinforcing a behavior each time it occurs

Explanation:

Continuous reinforcement is a schedule in which every occurrence of the target behavior is immediately rewarded. It is the most effective schedule for teaching a new behavior because it establishes a strong and direct connection between the behavior and the reward. For example, when training a dog to sit, giving the dog a treat every single time it sits ensures the dog quickly learns that sitting results in a positive consequence. Similarly, in Skinner’s experiments, rats learned to press a lever because each press reliably delivered food. The immediacy and consistency of reinforcement make continuous reinforcement powerful for initial learning. However, behaviors learned under continuous reinforcement can extinguish quickly once reinforcement stops, since the learner expects a reward every time.

Why Other Options Are Wrong:

A. Reinforcing a behavior only after a set number of responses

This describes a fixed-ratio schedule, not continuous reinforcement. In a fixed-ratio schedule, reinforcement comes after a predictable number of responses (e.g., every fifth lever press). While it increases response rates, it is not as effective for initially teaching a new behavior.

C. Reinforcing a behavior after an unpredictable number of responses

This is a variable-ratio schedule. Reinforcement happens after an unpredictable number of responses, such as in gambling or slot machines. This schedule creates high response rates and resistance to extinction but does not provide reinforcement for every behavior, unlike continuous reinforcement.

D. Reinforcing a behavior at varying time intervals regardless of the number of responses

This is a variable-interval schedule. Reinforcement is based on the passage of unpredictable amounts of time, not on each instance of the behavior. For example, checking your email and finding a new message at random times fits this schedule, but it does not reinforce every single behavior.

Correct Answer:

B. Because research shows gambling activates brain reward centers involving dopamine, similar to addictive drugs

Explanation:

Modern neuroscience has demonstrated that gambling stimulates the brain’s reward system, particularly the ventral striatum, where dopamine plays a key role. Importantly, “near misses” also trigger dopamine release, reinforcing the gambling behavior even without a win. These effects are remarkably similar to the brain activity caused by addictive drugs such as cocaine and heroin. Because of this overlap in brain mechanisms, the DSM-5 reclassified gambling as an addiction rather than an impulse control disorder.

Why Other Options Are Wrong:

A. Because gambling behavior is always learned through fixed-interval reinforcement schedules

This is incorrect because gambling relies on variable-ratio reinforcement, not fixed-interval. Fixed-interval schedules do not capture the unpredictability of gambling rewards.

C. Because gamblers only experience reinforcement when they win money, which strengthens behavior patterns

This oversimplifies gambling. Research shows even “near misses” without actual rewards release dopamine and reinforce behavior, so wins alone do not explain gambling addiction.

D. Because gambling is primarily a problem of poor self-control and impulsivity, not brain chemistry

Earlier DSM versions classified gambling under impulse control disorders. However, current evidence highlights neurochemical processes involving dopamine, making brain chemistry a central factor in its addictive nature.

Correct Answer:

B. Negative reinforcement removes an unpleasant stimulus to increase a behavior, while punishment decreases a behavior

Explanation:

Negative reinforcement and punishment are often confused, but they serve very different purposes. Negative reinforcement strengthens behavior by removing something unpleasant (e.g., fastening a seatbelt stops the car’s beeping, so seatbelt use increases). Punishment, on the other hand, always decreases a behavior. Punishment can be positive (adding an unpleasant stimulus, like scolding) or negative (removing a pleasant stimulus, like taking away a toy). Thus, reinforcement—positive or negative—always increases behavior, while punishment—positive or negative—always decreases it.

Why Other Options Are Wrong:

A. Negative reinforcement decreases a behavior, while punishment increases a behavior

This is the exact opposite of the correct definitions.

C. Negative reinforcement adds a pleasant stimulus to increase a behavior, while punishment removes a stimulus to increase a behavior

Adding a pleasant stimulus describes positive reinforcement, not negative reinforcement, and punishment never increases behavior.

D. Negative reinforcement and punishment are the same because both reduce unwanted behavior

This is incorrect—negative reinforcement increases a behavior, while punishment decreases it.

Correct Answer:

B. Acquisition

Explanation:

Acquisition is the first stage of classical conditioning in which a neutral stimulus is repeatedly paired with an unconditioned stimulus. Through this process, the neutral stimulus begins to trigger the same response as the unconditioned stimulus. At this point, the neutral stimulus becomes a conditioned stimulus, and the learned reaction is called the conditioned response. For example, in Pavlov’s experiment, the bell became a conditioned stimulus after repeated pairings with food.

Why Other Options Are Wrong:

A. Extinction

Extinction occurs when the conditioned stimulus is repeatedly presented without the unconditioned stimulus, causing the conditioned response to weaken or disappear.

C. Spontaneous recovery

This refers to the reappearance of a conditioned response after a period of extinction, not the initial learning phase.

D. Generalization

Generalization occurs when stimuli similar to the conditioned stimulus also produce the conditioned response, not during the initial learning stage.
