All questions

Question 1

A patient developed a phobia of needles (trypanophobia) after a painful injection. Initially, the fear was specific to hypodermic needles at the doctor's office. If stimulus generalization were to occur, which of the following outcomes would be most likely?

  1. The patient's fear of needles at the doctor's office would gradually diminish over time through extinction.
  2. The patient would begin to experience anxiety when seeing other sharp, pointed objects like sewing needles or safety pins. (correct answer)
  3. The patient would develop a new fear of the doctor's office itself, even when no needles are present.
  4. The patient would only experience fear when receiving an injection, but not when simply seeing a needle.
Explanation: The correct answer is B. Stimulus generalization is the tendency for a conditioned response (fear) to be evoked by stimuli that are similar to the original conditioned stimulus (hypodermic needle). Sewing needles and safety pins share the physical characteristics of being small, sharp, and metallic, making them likely candidates for generalization. A describes extinction. C describes higher-order conditioning, where the doctor's office (a neutral stimulus paired with the needle) becomes a conditioned stimulus. D describes stimulus discrimination, the opposite of generalization.

Question 2

A preschooler loves to spend free time drawing with crayons. A well-intentioned teacher starts a 'Super Artist' program, giving the child a gold star for every picture they complete. After a few weeks of the program, the teacher notices the child rarely chooses to draw during free time anymore and only draws when the gold stars are being offered. This change in the child's behavior can be best explained by:

  1. the Premack principle, as the less-preferred activity of drawing is being reinforced by the more-preferred activity of getting stars.
  2. stimulus generalization, as the child's interest in art has generalized to an interest in collecting stars.
  3. learned helplessness, as the child feels a lack of control over their artistic ability and gives up.
  4. the overjustification effect, as providing an external reward for an intrinsically enjoyable activity has diminished the intrinsic motivation. (correct answer)
Explanation: The correct answer is D. The overjustification effect occurs when an expected external incentive such as money or prizes (gold stars) decreases a person's intrinsic motivation to perform a task. The child initially drew for the sheer joy of it (intrinsic motivation). When the drawing was explicitly rewarded, the child's motivation shifted from internal ('I draw because I like it') to external ('I draw to get stars'). When the external reward is not available, the motivation is gone. A is an incorrect application of the Premack principle. B and C describe unrelated learning phenomena.

Question 3

In a classic study, three groups of rats were placed in a maze. Group A was rewarded with food each time they reached the end. Group B was never rewarded. Group C was not rewarded for the first 10 days but began receiving a reward on the 11th day. Group A rats gradually improved their speed and reduced errors. Group B rats showed little improvement. Group C rats showed little improvement for 10 days, but on day 11, their performance improved dramatically, quickly surpassing Group A.

The rapid improvement of Group C after day 10 best supports the concept of:

  1. instinctive drift, where learned behaviors are replaced by innate ones.
  2. shaping, where behavior is guided through successive approximations.
  3. latent learning, where learning occurs without reinforcement but is not demonstrated until a reinforcer is introduced. (correct answer)
  4. continuous reinforcement, where learning is fastest because every correct response is rewarded.
Explanation: The correct answer is C. This scenario describes Edward Tolman's classic experiment on latent learning and cognitive maps. The rats in Group C were clearly learning the maze layout during the first 10 days, but this learning was 'latent' or hidden because they had no motivation to demonstrate it. Once reinforcement was introduced, they quickly used their 'cognitive map' of the maze to perform very efficiently. A is incorrect as it describes the opposite phenomenon. B is a training technique not used here. D describes the schedule for Group A but doesn't explain the sudden, dramatic improvement of Group C.

Question 4

Two teams of factory workers are paid for producing widgets. Team A is paid $1 for every widget produced (continuous reinforcement). Team B is paid $10 after producing an average of 10 widgets, with the exact number changing for each payout (variable-ratio reinforcement). If the payment system is suddenly discontinued for both teams, which team is likely to continue producing widgets for a longer time, and why?

  1. Team B, because behaviors learned on partial reinforcement schedules are more resistant to extinction. (correct answer)
  2. Team A, because the strong and immediate connection between each behavior and its reward makes the behavior more durable.
  3. Team A, because the frustration of not being paid for every single widget will cause them to work harder to get the reward back.
  4. Team B, because the unpredictability of the reward created a form of learned helplessness, leading to persistence.
Explanation: When you encounter questions about reinforcement schedules and extinction, focus on how different reward patterns affect behavior persistence after rewards stop. Team B will continue working longer because partial reinforcement schedules create stronger resistance to extinction than continuous reinforcement. Under variable-ratio reinforcement, Team B never knew exactly when the next reward would come—sometimes after 8 widgets, sometimes after 12—so they learned to persist through periods without rewards. This uncertainty actually strengthens the behavior because the brain interprets the absence of reward as just another delay before the next payout. In contrast, Team A received a reward after every single widget under continuous reinforcement. When payments suddenly stop, they immediately notice something is wrong because they expect a reward after each behavior. This makes extinction happen much faster. Looking at the wrong answers: Option B incorrectly assumes immediate reinforcement creates more durable behavior—it actually makes extinction faster because the pattern break is obvious. Option C misapplies frustration theory; while Team A might initially work harder, this won't sustain them longer than Team B's extinction-resistant learning. Option D incorrectly invokes learned helplessness, which involves learning that responses don't matter—the opposite of what variable-ratio schedules create. Study tip: Remember the key principle: partial reinforcement (especially variable schedules) creates behaviors that are harder to extinguish than continuous reinforcement. This appears frequently on psychology exams, so memorize "partial = persistent."

Question 5

The experience of checking a social media feed, where compelling content appears unpredictably after a variable number of scrolls, is often maintained by which principle of reinforcement, and what is the likely behavioral outcome?

  1. Variable-interval schedule, resulting in a slow, steady rate of responding that is moderately resistant to extinction.
  2. Variable-ratio schedule, resulting in a high, steady rate of responding that is very resistant to extinction. (correct answer)
  3. Fixed-ratio schedule, resulting in a high rate of responding with pauses after reinforcement, which is easily extinguished.
  4. Continuous reinforcement, resulting in rapid learning but also very rapid extinction once reinforcement stops.
Explanation: The correct answer is B. Reinforcement (seeing interesting content) is delivered after an unpredictable number of responses (scrolls), which is the definition of a variable-ratio (VR) schedule. VR schedules are known for producing high, steady rates of responding with little to no pausing. They are also famously the most resistant to extinction, which helps explain the persistent, habitual nature of checking social media. A is incorrect because a variable-interval schedule is based on time, not the number of responses. While it produces steady responding, the VR schedule better fits the action of scrolling and produces higher response rates. C and D are incorrect because the reinforcement is not fixed or continuous.

Question 6

A child in a grocery store begins to cry and scream because he wants a candy bar. The parent initially says no, but the screaming intensifies. After several minutes of the loud tantrum, the parent gives in and buys the candy bar. The child immediately quiets down.

From the parent's perspective, the act of giving the child the candy bar is being influenced by which process?

  1. Positive reinforcement, because giving the candy adds a pleasant stimulus (quiet) to the environment.
  2. Negative reinforcement, because giving the candy removes an aversive stimulus (the screaming) from the environment. (correct answer)
  3. Positive punishment, because giving the candy adds an aversive consequence (spoiling the child) for the parent.
  4. Negative punishment, because the parent loses control of the situation, which is the removal of a desirable state.
Explanation: The correct answer is B. This question requires analyzing the situation from the parent's point of view. The parent's behavior is buying the candy. The consequence of this behavior is the removal of the child's loud, aversive screaming. Since the parent's behavior (giving candy) leads to the removal of an unpleasant stimulus, making the parent more likely to give in again in the future, this is negative reinforcement. A is incorrect because nothing pleasant is being added; rather, something unpleasant is being removed. C and D are incorrect because the consequence (cessation of screaming) makes the parent's behavior more likely in the future, meaning it is reinforcement, not punishment.

Question 7

A mother decides to use extinction to eliminate her toddler's whining for a snack before dinner. For the first two days, whenever the toddler starts whining, the mother calmly ignores the behavior and does not provide a snack. What is the most likely immediate outcome on the third day when the toddler begins whining?

  1. The whining will temporarily increase in frequency and intensity before it starts to decrease. (correct answer)
  2. The whining behavior will be significantly reduced or completely absent.
  3. The child will start whining in other situations, such as at bedtime, due to stimulus generalization.
  4. The child will stop whining but will spontaneously start again a week later.
Explanation: When you encounter questions about extinction in operant conditioning, focus on understanding the typical pattern of behavior change during the extinction process, not just the end result. Extinction occurs when a previously reinforced behavior is no longer followed by reinforcement. However, behavior doesn't simply disappear immediately. Instead, there's a predictable pattern: when reinforcement stops, the behavior typically shows an "extinction burst" - a temporary increase in both frequency and intensity before it begins to decline. This happens because the organism essentially "tries harder" to obtain the reinforcement that previously worked. In this scenario, the toddler's whining was previously reinforced (likely by receiving snacks), so when mom stops providing snacks, we'd expect the whining to intensify on day three as the child escalates the behavior that used to work. Answer A correctly identifies this extinction burst phenomenon. Answer B is incorrect because significant reduction typically doesn't occur until after the extinction burst phase. The behavior needs time to weaken once reinforcement is consistently withheld. Answer C describes stimulus generalization, but this refers to a learned response occurring in new situations, not the immediate intensification during extinction. Answer D describes spontaneous recovery, which can happen after extinction appears complete, but this occurs much later (days or weeks), not on day three of the process. Remember: extinction rarely proceeds smoothly. Expect behaviors to get worse before they get better, and prepare for this temporary intensification when implementing extinction procedures.

Question 8

A person successfully used a behavior modification plan to quit snacking on junk food late at night. For several weeks, they have not snacked and no longer feel the urge. One evening, while watching a movie series they used to binge-watch while eating chips, they suddenly feel an intense, unexpected craving for chips. This sudden re-emergence of the craving best illustrates which learning phenomenon?

  1. Stimulus discrimination, as the craving only occurs in a specific context.
  2. Spontaneous recovery, as a previously extinguished conditioned response has reappeared. (correct answer)
  3. Second-order conditioning, as the movie has become a conditioned stimulus for snacking.
  4. Negative reinforcement, as the craving is an aversive state they wish to remove.
Explanation: The correct answer is B. Spontaneous recovery is the reappearance of a conditioned response (in this case, the craving, which is a CR) after a period of time has passed since extinction. The craving was extinguished, but the presentation of a powerful conditioned stimulus (the movie series) after a rest period caused it to return. A is incorrect; while the context is specific, the key phenomenon is the reappearance of the response after it was extinguished. C is a plausible description of how the movie became a CS, but it doesn't describe the return of the craving after extinction, which is the core of the question. D describes a mechanism that might drive snacking behavior but doesn't explain the sudden re-emergence of the craving itself.

Question 9

A preschooler loves to spend free time drawing with crayons. A well-intentioned teacher starts a 'Super Artist' program, giving the child a gold star for every picture they complete. After a few weeks of the program, the teacher notices the child rarely chooses to draw during free time anymore and only draws when the gold stars are being offered. This change in the child's behavior can be best explained by:

  1. the Premack principle, as the less-preferred activity of drawing is being reinforced by the more-preferred activity of getting stars.
  2. stimulus generalization, as the child's interest in art has generalized to an interest in collecting stars.
  3. learned helplessness, as the child feels a lack of control over their artistic ability and gives up.
  4. the overjustification effect, as providing an external reward for an intrinsically enjoyable activity has diminished the intrinsic motivation. (correct answer)
Explanation: The correct answer is D. The overjustification effect occurs when an expected external incentive such as money or prizes (gold stars) decreases a person's intrinsic motivation to perform a task. The child initially drew for the sheer joy of it (intrinsic motivation). When the drawing was explicitly rewarded, the child's motivation shifted from internal ('I draw because I like it') to external ('I draw to get stars'). When the external reward is not available, the motivation is gone. A is an incorrect application of the Premack principle. B and C describe unrelated learning phenomena.

Question 10

A patient developed a phobia of needles (trypanophobia) after a painful injection. Initially, the fear was specific to hypodermic needles at the doctor's office. If stimulus generalization were to occur, which of the following outcomes would be most likely?

  1. The patient's fear of needles at the doctor's office would gradually diminish over time through extinction.
  2. The patient would begin to experience anxiety when seeing other sharp, pointed objects like sewing needles or safety pins. (correct answer)
  3. The patient would develop a new fear of the doctor's office itself, even when no needles are present.
  4. The patient would only experience fear when receiving an injection, but not when simply seeing a needle.
Explanation: The correct answer is B. Stimulus generalization is the tendency for a conditioned response (fear) to be evoked by stimuli that are similar to the original conditioned stimulus (hypodermic needle). Sewing needles and safety pins share the physical characteristics of being small, sharp, and metallic, making them likely candidates for generalization. A describes extinction. C describes higher-order conditioning, where the doctor's office (a neutral stimulus paired with the needle) becomes a conditioned stimulus. D describes stimulus discrimination, the opposite of generalization.

Question 11

An animal trainer is teaching a sea lion to balance a ball on its nose. The sea lion will occasionally touch the ball with its nose but quickly loses interest. The trainer needs to build this behavior into a stable, balanced pose. The trainer has a bucket of fish to use as reinforcement.

Which of the following applications of shaping would be the most effective next step for the trainer to take?

  1. Wait until the sea lion perfectly balances the ball for at least two seconds before giving it a fish.
  2. Give the sea lion a fish every time it looks at the ball to build a strong initial association.
  3. Give the sea lion a fish only for behaviors that are closer approximations of the final goal, such as touching the ball for a slightly longer duration. (correct answer)
  4. Present the fish at the same time the sea lion touches the ball to create a classical conditioning link between the ball and the food.
Explanation: The correct answer is C. Shaping involves reinforcing successive approximations of a target behavior. The sea lion already touches the ball, so the next logical step is to reinforce a slightly better version of that behavior—touching it for longer, or pushing it up slightly. This gradually moves the animal toward the final goal. A is incorrect because it demands the final behavior without reinforcing the intermediate steps, which is the opposite of shaping. B is reinforcing a behavior that the animal has already mastered (looking at the ball) and won't move the process forward. D confuses operant shaping with classical conditioning; the reinforcement (fish) should follow the desired behavior, not be presented simultaneously with the stimulus.

Question 12

A person eats a novel dish of spicy squid for the first time at a restaurant and hours later comes down with a severe stomach flu. Despite knowing intellectually that the flu, not the squid, caused the illness, the person develops a powerful, long-lasting aversion to the taste and smell of squid. Which principle best accounts for the rapid and robust nature of this learning?

  1. Stimulus contiguity, because the squid (CS) and illness (US) occurred close enough in time to form a strong association.
  2. Repeated pairings, because even a single strong pairing of a CS and US can be sufficient for conditioning.
  3. Biological preparedness, because organisms are evolutionarily predisposed to form certain associations, like taste and nausea, over others. (correct answer)
  4. Higher-order conditioning, because the restaurant (a neutral stimulus) was paired with the squid (CS), leading to a dislike of the restaurant.
Explanation: The correct answer is C. This is a classic example of taste aversion learning, which is a powerful demonstration of biological preparedness. Organisms are biologically wired to quickly associate novel tastes (CS) with gastrointestinal distress (US), even with a long delay between them. This has survival value. A is incorrect because the contiguity is actually very weak (hours pass), which is what makes this type of learning so unusual compared to standard classical conditioning. B is a distractor; while single-trial learning can occur, the key reason it happens so powerfully in this specific context (taste and nausea) is biological preparedness. D describes a different phenomenon that isn't the primary focus of the question.

Question 13

A therapist is treating a client with an intense phobia of elevators using systematic desensitization. The treatment involves creating a hierarchy of anxiety-provoking situations, teaching the client progressive muscle relaxation, and then having the client imagine each situation from the hierarchy while in a state of deep relaxation. The therapist notes that progress is only made when the client can successfully maintain a state of relaxation while vividly imagining a feared step.

Based on the principles of classical conditioning, which of the following is the most critical component for the therapeutic success described in the passage?

  1. The repeated presentation of the conditioned stimulus (elevator-related thoughts) without the unconditioned stimulus (a traumatic event).
  2. The pairing of the conditioned stimulus (elevator-related thoughts) with a new response (relaxation) that is incompatible with the conditioned response (fear). (correct answer)
  3. The client's cognitive reappraisal of the irrationality of their fear, which allows for new learning to occur.
  4. The gradual increase in the intensity of the imagined scenarios, which prevents stimulus generalization to other enclosed spaces.
Explanation: The correct answer is B. Systematic desensitization works primarily through counterconditioning, where the conditioned stimulus (the feared object, e.g., thoughts of an elevator) is paired with a new response (relaxation) that is physiologically incompatible with the conditioned response of fear. By pairing the feared stimulus with relaxation, the fear response is weakened and replaced. A describes extinction, which is a component, but the active pairing with an incompatible response (counterconditioning) is the core mechanism that makes this therapy particularly effective. C describes a cognitive therapy approach, not the behavioral mechanism of systematic desensitization. D describes the construction of the anxiety hierarchy, which is part of the procedure, but it's the pairing with relaxation (counterconditioning) that is the critical therapeutic component for success at each step.

Question 14

During a class discussion, one student offers a particularly insightful comment, and the teacher responds with enthusiastic praise, saying, 'That's a fantastic point, and it connects perfectly to our last topic!' Another student, who is usually hesitant to speak, observes this interaction.

Based on the principles of observational learning, what is the most likely effect of the teacher's praise on the hesitant student's future behavior in class discussions?

  1. The student is more likely to participate, due to experiencing vicarious reinforcement. (correct answer)
  2. The student is less likely to participate, due to vicarious punishment from seeing another student put on the spot.
  3. The student's behavior is unlikely to change, as the reinforcement was not delivered to them directly.
  4. The student will be classically conditioned to feel positive emotions when the praised student speaks.
Explanation: The correct answer is A. This scenario illustrates vicarious reinforcement, a key component of observational learning. The hesitant student observes another person (the model) being reinforced (praised) for a behavior (speaking up). This makes the observer more likely to engage in that behavior in the future. B is incorrect because the consequence was positive (praise), not punishing. C is incorrect because observational learning theory explicitly states that direct reinforcement is not necessary for learning to occur. D confuses observational learning with classical conditioning; while the student might feel positive, the primary effect on their overt behavior is best described by vicarious reinforcement.

Question 15

A middle school teacher implements a token economy to encourage homework completion. Students receive a 'credit' for each completed assignment, and they can exchange 10 credits for 30 minutes of free time on Friday. After several weeks, the teacher observes that many students complete their assignments early in the week but their effort significantly drops off by Wednesday and Thursday, with a sudden rush of completions on Friday morning.

Which learning principle best explains the observed pattern of student work?

  1. The students are on a fixed-ratio schedule of reinforcement, leading to a high rate of response near the time of reinforcement.
  2. The students are on a fixed-interval schedule of reinforcement, leading to a post-reinforcement pause and a scallop-shaped response pattern. (correct answer)
  3. The free time is not a potent enough primary reinforcer to maintain consistent behavior throughout the week.
  4. The delay between earning the final credit and receiving the reward is too long, leading to discounting of the reinforcer.
Explanation: The correct answer is B. The reinforcement (free time) is delivered at a fixed time (Friday), contingent on meeting the requirement. This is a fixed-interval schedule. A characteristic pattern of responding on a fixed-interval schedule is a 'scallop effect': a pause in responding after reinforcement, followed by an accelerating rate of response as the end of the interval approaches. This perfectly matches the students' behavior of slacking off mid-week and rushing on Friday morning. A is incorrect because a fixed-ratio schedule (reinforcement after a fixed number of responses) typically produces a high, steady rate of response followed by a brief pause, not the scalloping pattern described. C is incorrect as the rush of work on Friday shows the reinforcer is potent. D describes delay discounting, which is a real phenomenon, but the specific pattern of behavior (scalloping) is better explained by the nature of the fixed-interval schedule.

Question 16

A young boy watches his older sister consistently put her toys away after playing. Their mother always praises the sister enthusiastically, saying, 'You are such a great helper!' One day, the mother sees the young boy attempting to put his own large, clumsy blocks into a small box. He is not very effective but is clearly mimicking his sister's actions.

According to Albert Bandura's theory of observational learning, the boy's attempt to put his blocks away, despite his difficulty, best illustrates the operation of which necessary condition?

  1. Attention, as the boy had to notice his sister's behavior and the associated praise from his mother.
  2. Retention, as the boy had to remember the sequence of actions his sister performed to enact them later.
  3. Reproduction, as the boy is physically attempting to convert the stored mental representation into overt action. (correct answer)
  4. Motivation, as the boy is driven by the vicarious reinforcement his sister received from their mother.
Explanation: The correct answer is C. The question specifically asks about the boy's attempt to perform the action. This directly relates to 'reproduction,' which is the step where the observer tries to physically replicate the modeled behavior. The description of his clumsiness highlights that this is about the physical act itself. While A, B, and D are all necessary conditions for the entire observational learning process to be successful, the specific part of the scenario described—the physical attempt—is the reproduction phase. A (attention) and B (retention) must have happened earlier. D (motivation) explains why he is trying, but C describes the what he is doing.

Question 17

A client is using a biofeedback machine to learn to control tension headaches. The machine is connected to sensors on the client's forehead that measure muscle tension. When the client successfully relaxes these muscles, the machine emits a pleasant, low-pitched tone. When the muscles are tense, it emits a harsh, high-pitched tone.

In this application of operant conditioning, what serves as the positive reinforcer for the client's behavior of relaxing their forehead muscles?

  1. The reduction of headache pain.
  2. The therapist's verbal praise for progress.
  3. The absence of the harsh, high-pitched tone.
  4. The pleasant, low-pitched tone. (correct answer)
Explanation: When you encounter questions about operant conditioning, focus on identifying what directly follows a behavior and increases its likelihood of recurring. In operant conditioning, a positive reinforcer is something added to the environment that strengthens the target behavior. The pleasant, low-pitched tone (D) is the positive reinforcer because it's the immediate, tangible stimulus presented when the client successfully relaxes their forehead muscles. This tone directly follows the desired behavior and serves to reinforce it, making the client more likely to repeat the muscle relaxation in the future. Let's examine why the other options don't qualify as positive reinforcers in this scenario. The reduction of headache pain (A) is the ultimate therapeutic goal, but it's not the immediate reinforcer being delivered by the biofeedback machine - it's a longer-term consequence that may occur over time. The therapist's verbal praise (B) isn't mentioned in the passage at all, so it's not part of this specific conditioning setup. The absence of the harsh, high-pitched tone (C) represents negative reinforcement (removal of an unpleasant stimulus), not positive reinforcement, even though it might also strengthen the behavior. Remember that in operant conditioning questions, positive reinforcement always involves adding something desirable immediately after the target behavior occurs. Look for what's being given or presented to the subject, not what's being taken away or what might happen later as a secondary effect.

Question 18

A student wants to establish a consistent habit of studying for their psychology class for one hour each evening, a behavior they currently find unappealing. However, the student reliably spends an hour playing a favorite video game every night. According to the Premack principle, how should the student arrange their evening activities to best promote the studying habit?

  1. Use playing the video game for one hour as a reward that is only available after completing one hour of studying. (correct answer)
  2. Play the video game for an hour first to get it out of the way, then use the remaining motivation to study psychology.
  3. Alternate between 15 minutes of studying and 15 minutes of video games to break up the monotony of the less-preferred activity.
  4. Promise to buy a new video game at the end of the week if they study for an hour every night.
Explanation: When you encounter questions about behavior modification and habit formation, think about reinforcement principles that explain how we can use preferred activities to strengthen less preferred ones. The Premack principle states that a high-probability behavior (something you naturally do often) can serve as a reinforcer for a low-probability behavior (something you avoid or do rarely). Essentially, you can use an activity someone enjoys to motivate them to complete a less appealing task. In this scenario, playing video games is the high-probability behavior, while studying psychology is the low-probability behavior that needs strengthening. Answer A correctly applies the Premack principle by making the preferred activity (video games) contingent upon completing the less preferred activity (studying). This creates a natural reinforcement schedule where studying becomes the pathway to the rewarding video game time. Answer B reverses the principle, giving the reward first, which eliminates any motivational benefit and doesn't create the necessary contingency relationship. Answer C describes a different technique called activity scheduling or breaking tasks into smaller chunks, but doesn't establish the contingent relationship that defines the Premack principle. Answer D introduces an external reward (buying a new game) rather than using the existing preferred behavior as the reinforcer. Remember that the Premack principle is about leveraging what someone already enjoys doing regularly to motivate behaviors they find less appealing. Look for the contingency: preferred activity comes after, not before, the target behavior you want to strengthen.

Question 19

In a form of aversion therapy for alcohol use disorder, a client is given a drug that causes severe nausea whenever they consume alcohol. The therapy involves the client taking the drug and then consuming a small amount of an alcoholic beverage under medical supervision.

In this classical conditioning procedure, what is the unconditioned stimulus (US)?

  1. The alcoholic beverage.
  2. The feeling of nausea.
  3. The drug that induces nausea. (correct answer)
  4. The reduction in cravings for alcohol.
Explanation: The correct answer is C. To identify the components, we must break down the automatic, unlearned relationship. The drug reliably and automatically causes nausea. Therefore, the drug is the unconditioned stimulus (US) because it elicits a response without prior learning. The nausea is the unconditioned response (UR) to the drug. The alcoholic beverage is the neutral stimulus that, through pairing with the drug, becomes the conditioned stimulus (CS). The goal is for the alcohol (CS) to eventually elicit nausea (now a conditioned response, CR) on its own. D is the therapeutic goal, not a component of the conditioning itself.

Question 20

A sales manager wants to increase the total number of calls her employees make each day. She wants a payment bonus system that will encourage a high, steady rate of calling with minimal pausing. Which of the following reinforcement schedules would be most effective for achieving this specific goal?

  1. Fixed-interval, with a bonus given for making at least one call in every 30-minute period.
  2. Fixed-ratio, with a bonus given for every 25 calls made.
  3. Variable-interval, with a bonus given at random times during the day for employees who are currently on a call.
  4. Variable-ratio, with a bonus given after an unpredictable number of calls. (correct answer)
Explanation: The correct answer is D. Variable-ratio (VR) schedules are known to produce the highest and steadiest rates of responding with the least amount of pausing. Because the reinforcement is unpredictable based on the number of responses, the worker is motivated to keep responding at a high rate. A (Fixed-interval) would produce scalloping (a rush of calls near the end of the interval). B (Fixed-ratio) produces a high rate but is often characterized by a post-reinforcement pause, which the manager wants to avoid. C (Variable-interval) produces a steady rate, but not as high as a VR schedule.
