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

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:

C. A strict form of behaviorism suggesting even complex functions like language are stimulus-outcome associations

Explanation:

Radical behaviorism, developed by B. F. Skinner, extended the principles of operant conditioning to explain even higher mental processes. Skinner argued that language and other complex behaviors are not unique cognitive abilities but learned stimulus-response patterns reinforced over time. He treated the mind as a “black box,” focusing solely on observable behaviors and their environmental determinants. This made his approach “radical” compared to other behaviorists.

Why Other Options Are Wrong:

A. A theory that human language and thought processes are innate and independent of learning

This reflects Noam Chomsky’s nativist perspective, not Skinner’s radical behaviorism.

B. A perspective that emphasizes studying cognition and internal thought as the key to learning

This describes cognitive psychology, which opposes radical behaviorism by focusing on mental processes.

D. A theory that rejects reinforcement and focuses only on biological predispositions

This is incorrect because Skinner’s theory is built entirely on reinforcement principles, not biological determinism.

Correct Answer: B. Learned behaviors are acquired through experience, while instincts and reflexes are innate and biologically determined

Explanation:

Learned behaviors develop through interaction with the environment, practice, reinforcement, or observation. They are not present at birth but acquired over time, such as playing a sport or learning a language. Instincts, like migration in birds, and reflexes, like the knee-jerk reaction, are automatic, innate, and do not require learning. This distinction highlights how experience shapes learned behaviors, while instincts and reflexes are built into the nervous system.Why Other Options Are Wrong:

A. Learned behaviors are automatic responses present at birth, while instincts develop only in adulthood

This reverses the definitions—learned behaviors are not present at birth, and instincts appear early in life.

C. Learned behaviors are simple, involuntary actions, while instincts and reflexes involve complex decision-making

Reflexes are simple and involuntary, not learned; instincts are automatic, not based on decision-making.

D. Learned behaviors are genetically programmed, while instincts and reflexes result from environmental conditioning

It is the opposite: instincts and reflexes are genetically programmed, while learned behaviors arise from experience.

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. Extinction

Explanation:

Extinction occurs when the conditioned stimulus (CS) is repeatedly presented without the unconditioned stimulus (UCS), leading to a gradual weakening and eventual disappearance of the conditioned response (CR). For example, if Pavlov’s bell (CS) is rung but food (UCS) is no longer presented, the dog will eventually stop salivating (CR) to the bell. Extinction does not erase learning; it simply suppresses the conditioned response.

Why Other Options Are Wrong:

A. Acquisition

Acquisition is the initial learning stage where the CS and UCS are paired to form an association.

C. Generalization

Generalization occurs when stimuli similar to the conditioned stimulus also trigger the conditioned response.

D. Spontaneous recovery

Spontaneous recovery is when a previously extinguished conditioned response reappears after a pause, not the process of its decline.

Correct Answer:

B. Reinforcement occurs only after some, but not all, desired behaviors are performed

Explanation:

Partial reinforcement, also known as intermittent reinforcement, is a schedule where reinforcement does not happen every time the behavior occurs. Instead, reinforcement is delivered occasionally, based on either a fixed or variable schedule, tied to time (interval) or number of responses (ratio). This approach makes the learned behavior more resistant to extinction compared to continuous reinforcement. For example, if a child gets praised only sometimes when they clean their room, they may continue the behavior longer than if they were praised every single time.

Why Other Options Are Wrong:

A. Reinforcement is delivered every single time a behavior is performed

This describes continuous reinforcement, not partial. Continuous reinforcement is useful in teaching a new behavior, but it is not the same as intermittent reinforcement.

C. Reinforcement is given continuously without breaks, regardless of the behavior

This does not describe any recognized reinforcement schedule. Reinforcement must be linked to the target behavior to be effective in shaping or maintaining behavior.

D. Reinforcement occurs randomly without any relationship to the behavior

This is inaccurate because reinforcement schedules—whether fixed or variable—are always connected to the behavior or time. Random reinforcement unrelated to behavior would not effectively strengthen the desired response.

Correct Answer:

B. A student watches a tutorial video and then successfully fixes a bike chain

Explanation:

Observational learning occurs when individuals acquire new behaviors by watching others (models) and then imitating those behaviors. Unlike direct reinforcement, it relies on social influence and modeling. For example, a student who watches a YouTube tutorial and then applies the steps to fix a bike chain has learned through observation. Research suggests that mirror neurons help the brain simulate and replicate the observed behavior, facilitating imitation and skill learning.

Why Other Options Are Wrong:

A. A child receives candy every time they clean their room

This is operant conditioning with positive reinforcement, not observational learning. The child is reinforced directly rather than learning by watching others.

C. A worker increases productivity after receiving a paycheck every two weeks

This is a fixed-interval reinforcement schedule, not observational learning. It depends on time-based reinforcement, not modeling.

D. A gambler keeps playing slot machines because of unpredictable payouts

This is a variable-ratio reinforcement schedule, not observational learning. The persistence in gambling behavior is driven by unpredictably timed reinforcement, not imitation.

Correct Answer:

B. A stimulus that elicits a reflexive, natural response without prior learning

Explanation:

In classical conditioning, the unconditioned stimulus (UCS) naturally and automatically triggers a response without any learning involved. For example, food is a UCS because it elicits salivation in dogs without conditioning. The response it evokes is called the unconditioned response (UCR). This forms the foundation upon which associations are built when pairing a UCS with a neutral stimulus.

Why Other Options Are Wrong:

A. A stimulus that an organism learns to respond to only after conditioning

This describes a conditioned stimulus (CS), not an unconditioned stimulus.

C. A stimulus presented after behavior to increase the likelihood of its recurrence

This describes reinforcement in operant conditioning, not UCS in classical conditioning.

D. A stimulus that decreases behavior through punishment after repeated exposure

This reflects punishment in operant conditioning, not the role of an unconditioned stimulus.

Correct Answer:

B. A student receives a paycheck every two weeks regardless of performance

Explanation:

A fixed-interval reinforcement schedule provides reinforcement after a consistent, predictable amount of time has passed. The reinforcement does not depend on the number of responses, only on time. For example, paychecks given every two weeks or June’s pain medication available once per hour both demonstrate fixed intervals. This type of reinforcement tends to produce a "scalloped" response pattern, where behavior increases as the reinforcement time approaches.

Why Other Options Are Wrong:

A. A worker receives $20 for every five shirts they sew

This describes a fixed-ratio schedule because reinforcement is delivered after a specific number of responses (five shirts), not after a fixed amount of time.

C. A slot machine pays out after an unpredictable number of pulls

This is a variable-ratio schedule. The reinforcement is based on the number of responses, but the number required is unpredictable and constantly changing.

D. A dog gets a treat after every third time it rolls over

This also represents a fixed-ratio schedule, where reinforcement occurs after a set number of responses (every third rollover), not according to a time interval.
