Class 11 Psychology Chapter 5 Learning

Key Concept: Definition Recall

c) The ability to perform complex tasks smoothly and efficiently

[Solution Description] According to the syllabus, a skill is defined as the ability to perform complex tasks smoothly and efficiently.

Key Concept: Reinforcement Definition

c) To increase the likelihood of a behavior

[Solution Description] The main role of reinforcement in operant conditioning is to increase the probability or likelihood of a behavior occurring again in the future by presenting a stimulus after the desired behavior.

Key Concept: Automaticity

b) Automaticity

[Solution Description] The autonomous phase is characterized by automaticity in skilled performance, meaning actions are performed with minimal cognitive effort and attention.

Key Concept: Listening Problems

b) Difficulty in following oral directions

[Solution Description] Children with learning disabilities may exhibit listening problems not due to hearing issues but due to processing difficulties. This can manifest as difficulty in following oral directions.

Key Concept: Phase Identification

c) Autonomous

[Solution Description] The autonomous phase in skill acquisition is characterized by the ability to perform tasks with minimal conscious thought, reduced need for attention, and little to no external interference.

Key Concept: Basic Definition

c) A relatively permanent change in behavior

[Solution Description] Learning is described as a relatively permanent change in behavior due to experience, distinguishing it from changes due to other factors like fatigue or drugs.

Key Concept: Complex Scenario Analysis, Theoretical Implication, Integration with Other Concepts

d) The sound of rain is the CS; images of thunderstorms are the US; discomfort is the CR

[Solution Description]

Initially, the sound of rain is a neutral stimulus that does not elicit any response related to the storm phobia. However, when it precedes the presentation of images of thunderstorms (aversive US), which naturally cause discomfort (UR), the patient starts associating the sound of rain with the upcoming storm imagery. Over repeated pairings, the sound of rain becomes a conditioned stimulus (CS) eliciting conditioned discomfort (CR) even without the thunderstorm images.

Therefore, the sound of rain transforms into the CS, while the images of thunderstorms are the US triggering an original UR of discomfort. Eventually, the sound alone causes the CR of discomfort.

Key Concept: Occurrence

b) After a learned response is extinguished and some time has passed

[Solution Description] Spontaneous recovery occurs after a learned response has been extinguished and some time has passed. This means that the conditioned response (CR) comes back without any intervention, simply after the passage of time following extinction.

Key Concept: Attention and Hyperactivity

d) Attention deficits often lead to hyperactivity

[Solution Description] The syllabus states that attention disorders often lead to hyperactivity in learning-disabled children. This implies a causal relationship where difficulties in maintaining attention can result in increased impulsivity and excess movement, characteristic of hyperactivity.

Key Concept: Basic Definition

c) Social Learning

[Solution Description] Observational learning can also be referred to as imitation or social learning, where individuals learn by watching others.

Key Concept: Advanced Stimulus Interaction, Critical Thinking

d) Avoidance response

[Solution Description] In this scenario, the loud noise is an unconditioned stimulus (US) that naturally elicits a reflexive action such as covering the ears (unconditioned response or UR). The light, which initially did not elicit any ear-covering behavior, was repeatedly paired with the loud noise during conditioning. Over time, the light becomes a conditioned stimulus (CS), leading the individual to cover their ears even when the loud noise is not present. This represents a case of classical conditioning where the conditioned response (CR) is similar to the unconditioned response (UR). Since the CR (covering ears to light) mirrors the UR (covering ears to loud noise), it shows that the light has become an effective CS through its association with the US.

Key Concept: Operant Definition

b) A voluntary behavior that affects the environment to produce a consequence

[Solution Description] An operant is defined as a voluntary behavior that operates on the environment to produce consequences. It emphasizes the role of behavior in producing outcomes which are then subject to reinforcement or punishment.

Key Concept: Species Differences

b) Species have different sensory capacities and response abilities

[Solution Description] Different species have varying learning capacities because they possess unique sensory capabilities and neural processing systems. This means that while some species might excel at learning tasks involving visual cues, others might be better suited for auditory-based learning.

Key Concept: Specific Symptoms

c) Sequential processing disorder

[Solution Description] The difficulty in understanding the sequence of events or steps is often referred to as a problem with sequential processing, which can be considered a perceptual disorder related to learning disabilities. Children with this issue may struggle with tasks that require a specific order, such as following directions or organizing thoughts in writing.

Key Concept: Critical Analysis, Experimental Design

c) The time interval between the presentation of the CS and the US.

[Solution Description] Backward conditioning is generally considered less effective than other conditioning methods like delayed or trace conditioning. The critical factor influencing its effectiveness is primarily the time interval between the presentation of the CS and US. For backward conditioning to work, even minimally, the CS must accurately predict the occurrence of the US. Thus, the shorter the time interval, the higher the probability of establishing some level of conditioning.

Key Concept: Temporary vs Permanent

b) Change due to repeated experiences

[Solution Description] Learning involves relatively permanent changes in behavior as a result of experience, distinguishing it from temporary changes such as those caused by fatigue or drugs.

Key Concept: Space and Time Orientation

b) Space orientation and sense of time

[Solution Description]

Learning-disabled children may struggle with spatial orientation and understanding a sequence of events over time, leading to challenges in subjects that require these skills.

Key Concept: Basic Concept

c) Observational Learning

[Solution Description] Observational learning, also known as modeling, refers to the process where individuals learn new behaviors or skills by watching others perform them. This type of learning is a fundamental concept in social learning theory.

Key Concept: Stimulus Intensity, Stimulus Interaction

c) Assertion is true, but Reason is false.

[Solution Description] To evaluate the effectiveness of a conditioned stimulus, both its intensity and timing are critical factors. Higher intensity CS can lead to faster learning. However, the reason provided contradicts established knowledge; simultaneous conditioning typically requires more trials as the CS provides less predictive value about the US compared to delayed presentations. Thus, while assertion is true, the reasoning is false.

Key Concept: Insight Learning Definition

b) Learning through sudden flashes of understanding

[Solution Description] Insight learning refers to a type of learning that occurs suddenly through understanding, rather than trial and error. This form of learning involves grasping underlying principles in a problem-solving situation, as seen in Kohler’s experiments with chimpanzees.

Key Concept: Conceptual Understanding, Comparative Analysis

b) Group 2 conditions faster due to the rapid effects of aversive stimuli.

[Solution Description] Simultaneous conditioning involves presenting the conditioned stimulus (CS) and unconditioned stimulus (US) at the same time. In this context, aversive stimuli like loud noise typically condition more rapidly than appetitive stimuli like food because they evoke stronger, immediate reactions. Therefore, Group 2, receiving the aversive stimulus, is expected to develop the conditioned response faster than Group 1.

Key Concept: Advanced Conceptual Analysis, Critical Evaluation

b) Both Assertion and Reason are true, but Reason is NOT the correct explanation of Assertion.

[Solution Description] Insight learning is characterized by a sudden realization of solutions, which can appear without prior extensive trial and error. This process differs from traditional skill learning, where repetitive practice is crucial for moving through its phases of development. While both statements discuss types of learning processes, they address different aspects; insight learning does not follow the same path as skill learning. Thus, while both are true, the reason does not explain the assertion.

Key Concept: Insight Definition

b) Sudden realization

[Solution Description] Insight learning is a type of problem-solving that involves a sudden realization or understanding, rather than through trial and error. This means that the solution comes to mind abruptly after contemplating the problem for some time.

Key Concept: Definition Recall

b) Learning through sudden realization

[Solution Description] Insight learning is a type of cognitive learning where the solution to a problem suddenly becomes clear, often without trial and error.

Key Concept: Basic Definition

c) Modeling

[Solution Description] Observational learning is also known as modeling or social learning, as it involves learning by observing others.

Key Concept: Serial Anticipation

c) Serial Anticipation Method

[Solution Description] The process described is known as the “serial anticipation method”. In this method, each item in the sequence acts as a trigger or cue to recall the next item, facilitating memorization in order.

Key Concept: Real-World Application, Complex Scenario Analysis

b) The phone ringing

[Solution Description] In this scenario, the repeated association of bad news with the ringing of the phone leads to the development of anxiety whenever the phone rings. Here, the phone ringing is initially a neutral stimulus that becomes associated with the bad news (the unconditioned stimulus). Over time, the phone ringing alone triggers anxiety (the conditioned response), making it the conditioned stimulus.

Key Concept: Impact of Learning Disabilities

b) They may lead to long-term difficulties in social relations and employment opportunities.

[Solution Description]

If learning disabilities are not addressed, they can interfere with various aspects of an individual’s life beyond just academics. Specifically, learning disabilities can affect social interactions, self-esteem, and even career prospects due to challenges in communication and understanding. These impacts are pervasive and can continue into adulthood if not properly managed.

Key Concept: Definition Recall

b) A relatively permanent change in behavior produced by experience

[Solution Description] Learning is defined as any relatively permanent change in behavior or behavioral potential produced by experience or practice, according to the syllabus.

Key Concept: Continuous vs. Intermittent

a) Continuous

[Solution Description] A continuous reinforcement schedule means reinforcing the desired response each time it occurs, leading to faster learning but less resistance to extinction.

Key Concept: Experimental Design, Critical Thinking

c) More trials for appetitive, fewer for aversive

[Solution Description] According to classical conditioning principles, the nature of the unconditioned stimulus affects the speed at which conditioning occurs. Appetitive stimuli, like water for thirsty rats, typically require more trials for a conditioned response to be learned because they are less immediately impactful compared to aversive stimuli, which often induce quicker learning due to their negative nature. Thus, the aversive stimulus will lead to faster conditioning in fewer trials.

Key Concept: Real-World Application, Conceptual Complexity

a) Shivering due to the cold

[Solution Description] Here, the sudden drop in temperature acts as an unconditioned stimulus as it naturally causes shivering, which is a physiological response aimed at generating body heat. The shivering that occurs directly due to the exposure to cold is the unconditioned response since it happens automatically and does not require prior learning. Feeling cold when seeing frost after repeated experiences signifies a conditioned response developed through association.

Key Concept: Determinants of Learning

a) Contiguous presentation of stimuli

[Solution Description] In classical conditioning, contiguity refers to how close together in time two stimuli are presented. It is an important determinant because it affects association; if two stimuli are presented closely together, they are more likely to be associated.

Key Concept: Impact on Learning

c) Leads to poorer performance

[Solution Description] Delayed reinforcement tends to result in poorer performance compared to immediate reinforcement. This is because immediate feedback is more effective in reinforcing the desired behavior quickly and consistently.

Key Concept: Attention Deficit Analysis

c) Hyperactivity

[Solution Description] Children with learning disabilities who have attentional deficiencies often exhibit hyperactivity as they struggle to focus on tasks. This inability to concentrate leads them to become restless and overactive, as they constantly seek new stimuli.

Key Concept: Detailed Example

c) Genetic predispositions facilitate easier formation of associations

[Solution Description] According to the syllabus on preparedness for learning, biological constraints and genetic endowment play significant roles in determining how easily a species can learn S-R or S-S associations. Animals that can be easily trained are likely those whose genetic makeup allows for efficient synaptic connections and neural pathways to form when exposed to these learning conditions.

Key Concept: Complex Reinforcement Scenarios, Punishment Limitations

c) The strategy created dependency on the presence of the reinforcing agent.

[Solution Description] The child’s behavior suggests that the positive reinforcement (praise) is contingent on the presence of the teacher, indicating that the reinforcement strategy has led to dependency on external cues. This implies that the reinforcement was not internalized, possibly due to inconsistent or weak application making it ineffective without direct supervision.

Key Concept: Phase Identification

d) Autonomous phase

[Solution Description] In the autonomous phase of skill acquisition, tasks are performed automatically with little conscious thought or attention, indicating a high level of proficiency.

Key Concept: Definition Recall

c) A relatively permanent change in behaviour produced by experience

[Solution Description] Learning is defined as a relatively permanent change in behaviour or behavioural potential produced by experience, distinguishing it from temporary changes such as those caused by fatigue or drugs.

Key Concept: Paired-Associates Basics

b) Stimulus

[Solution Description] In paired-associates learning, a stimulus-response pair is used for tasks like language learning. The first word in each pair acts as the stimulus that prompts recall of the second word, which is the response.

Key Concept: Reinforcement Frequency

b) Resistance to extinction decreases

[Solution Description] Initially, increasing the number of reinforcements enhances resistance to extinction as it strengthens the learned response. However, once the reinforcement reaches a critical level, further increases can reduce the resistance because the subject may become satiated or overly accustomed to the reinforcement schedule.

Key Concept: Sensory Misperception

c) A call-bell and the ring of a telephone

[Solution Description] Sensory misperception can cause children with learning disabilities to confuse sounds that are similar. They might have difficulty distinguishing between noises such as a call-bell and the ring of a telephone.

Key Concept: Phase Transition

b) Performance Plateau

[Solution Description] During skill learning, a performance plateau occurs when there is no apparent improvement in performance. This typically happens during the transition between different phases of skill acquisition.

Key Concept: Definition Recall

b) Reinforcement given intermittently, or only some of the time

[Solution Description] Intermittent reinforcement refers to a reinforcement schedule where behavior is rewarded only some of the time. This leads to behaviors that are more resistant to extinction compared to continuous reinforcement.

Key Concept: Skill Definition

a) Typing

[Solution Description] To define a skill, it is important to understand that a skill involves performing complex tasks smoothly and efficiently. Among the options provided, typing fits this definition as it requires coordination and efficiency in using a keyboard.

Key Concept: Complex Scenarios, Conditioning Effectiveness

c) Trace conditioning

[Solution Description] This scenario describes trace conditioning, where there is a time gap between the presentation of the CS and the US. Here, the tone (CS) is presented first, with a 1-second gap before the shock (US), which indicates trace conditioning.

Key Concept: Advanced Conceptual Application, Critical Thinking on Stimulus-Response

b) Unconditioned Stimulus

[Solution Description] Before conditioning occurs, food acts as an Unconditioned Stimulus (US) because it naturally and automatically triggers the Unconditioned Response (UR), which is salivation. There is no learning or conditioning required for this response; it is an innate and unlearned reflex that happens whenever food is presented to the dog. Thus, food is classified as the US in this scenario.

Key Concept: Comparative Analysis, Critical Evaluation

c) Classical conditioning may not tackle underlying cognitive factors influencing smoking behavior.

[Solution Description]

Classical conditioning might not address the internal cognitive motivations or reasons behind smoking, which operant conditioning can target by using positive reinforcement strategies, thus potentially offering longer-lasting changes.

Key Concept: Real-world Application

d) Navigating to a location you have never visited but have seen on a map before.

[Solution Description] An example of latent learning in real life is knowing a route to a place without having driven there before. A person might know how to get somewhere without ever needing to go there themselves; this knowledge becomes evident when they actually need to make the trip.

Key Concept: Real-world Application, Conceptual Integration

a) Appetitive

[Solution Description] Deep breathing exercises serve as an appetitive unconditioned stimulus because they naturally induce relaxation and comfort. The pairing with music helps the patient associate relaxation with the music over time.

Key Concept: Definition Recall

b) Generalisation

[Solution Description] In the context of operant conditioning, when a learned response is triggered because the stimulus has similarities to the original one, it is called “Generalisation.” This means the organism does not differentiate between the stimuli and responds similarly.

Key Concept: Role of Motivation

d) It energizes the organism to act

[Solution Description]

Motivation plays a vital role in operant conditioning as it provides the energy and drive necessary for an organism to engage in behavior that leads to reinforcement. Without motivation, even the availability of positive reinforcement may not encourage the desired behavior. It ensures that the organism remains active and willing to respond in anticipation of a reinforcer. This concept highlights that learning isn’t just about the availability of external rewards but also involves internal states driving the behavior.

Key Concept: Basic Definition

b) Reinforcement given after every desired response

[Solution Description] Continuous reinforcement occurs when reinforcement is delivered after every desired response. This means that each correct behavior or action is rewarded immediately, which helps in establishing a new behavior quickly.

Key Concept: Association Value

d) Familiarity

[Solution Description] The determinants of verbal learning include the length of the list, association values, and relations among items. Familiarity is related to meaningfulness of material rather than a direct determinant of verbal learning.

Key Concept: Second-order Conditioning, Real-World Application

c) The conditioned response would be happiness, similar to seeing the logo

[Solution Description] This scenario utilizes second-order conditioning principles. Initially, the brand logo becomes associated with the positive feeling of happiness induced by the cheerful music, making the logo a Conditioned Stimulus (CS) causing a Conditioned Response (CR) of happiness. Subsequently, when the visual effect is paired with the already established CS (logo), it can take on a similar conditioned association through second-order conditioning. Therefore, when the visual effect is later presented alone, it is expected to evoke the CR of happiness, demonstrating how associations can extend beyond direct pairings.

Key Concept: Continuous Reinforcement

b) Every time it occurs

[Solution Description] Continuous reinforcement involves reinforcing the desired response every time it occurs. This schedule is useful for establishing new behaviors quickly.

Key Concept: Motivation Influence on Behavior, Motivation Theory Application

a) Intrinsic motivation

[Solution Description]

To determine the type of motivation influencing this student’s behavior, we analyze the situation: The student excels in creative tasks, indicating a preference for activities that are intellectually stimulating and personally rewarding. Routine tasks lack such intrinsic appeal and thus might not engage the student as effectively. This suggests that the student’s behavior is primarily driven by intrinsic motivation, where personal satisfaction and intellectual engagement motivate performance.

Key Concept: Task Difficulty

b) Handling doorknobs

[Solution Description] Children with poor motor coordination find it difficult to perform tasks involving precise manual dexterity, such as manipulating small tools or objects.

Key Concept: Basic Definition

c) Social Learning

[Solution Description] Observational learning is also commonly referred to as social learning or modeling. It involves acquiring skills, knowledge, and behaviors by observing others.

Key Concept: Definition Recall

d) Reinforcement given after every response

[Solution Description] Continuous reinforcement involves providing reinforcement after every target response, which leads to consistently high response rates but also quick extinction once the reinforcement stops.

Key Concept: Advanced Conceptual Understanding, Theoretical Application

c) A temporal gap between CS and US leads to potential interference from other stimuli.

[Solution Description] In trace conditioning, there is a time gap between the end of the conditioned stimulus (CS) and the onset of the unconditioned stimulus (US). This gap can lead to weaker associative learning because during the interval, other stimuli may interfere or distract, weakening the association between the CS and US. In delayed conditioning, however, the CS overlaps with the US for some period, creating stronger temporal contiguity and resulting in quicker association.

Key Concept: Writing Challenges

b) Reversing letters like ‘b’ and ‘d’

[Solution Description] Children with dyslexia often struggle with reversing letters due to their difficulty in distinguishing between similar-looking letters such as ‘b’ and ‘d’. This symptom arises from challenges in visual perception, impacting their ability to organize verbal materials correctly.

Key Concept: Complex Conditioning Analysis, Discrimination Learning

d) Generalisation, as the response extends to a new stimulus.

[Solution Description] Initially, the dog learns to discriminate between Tone A and Tone B as only Tone A is consistently paired with food, resulting in a conditioned salivary response. However, if Tone B starts to elicit salivation, it suggests generalisation is occurring. This happens because the dog begins to respond similarly to stimuli that are similar to the conditioned stimulus, even if they were not reinforced in the same manner initially. Generalisation indicates that the association formed with the conditioned stimulus (Tone A) can extend to other non-reinforced stimuli (Tone B).

Key Concept: Comparative Analysis

d) Partial reinforcement

[Solution Description] Reinforcement schedules affect the durability of learned behavior under operant conditioning. Partial reinforcement, where responses are intermittently reinforced, leads to behaviors that are more resistant to extinction compared to continuous reinforcement. This occurs because organisms learn that persistence might eventually be rewarded even when reinforcement is not immediate.

Key Concept: Role of Organization & Categorization

c) By category

[Solution Description] Participants tend to use category clustering in free recall tasks. This means they will often remember words grouped by their categorical associations, rather than randomly or in the order presented.

Key Concept: Phase Identification

a) Cognitive Phase

[Solution Description] In Fitts’ model, the Cognitive Phase is characterized by the learner’s focus on understanding and memorizing instructions, which demands a high level of cognitive effort. This phase is primarily focused on getting to know the task requirements and necessary movements.

Key Concept: Experience Impact

a) To be cautious around hot objects

[Solution Description] When someone touches a hot stove, they quickly learn that it can cause pain and potential injury. This learning is the result of a single negative experience which teaches them not to touch hot surfaces again for their safety.

Key Concept: Schedules of Reinforcement

d) Continuous reinforcement

[Solution Description] Continuous reinforcement refers to a schedule where each desired behavior is reinforced, whereas intermittent reinforcement only reinforces some responses. Therefore, the correct answer is continuous reinforcement.

Key Concept: Complex Scenario Analysis, Cross-context Application

b) Aversive stimuli result in faster conditioning due to their stronger avoidance responses.

[Solution Description] An electric shock is highly aversive and typically requires very few trials to establish avoidance behavior due to its high intensity and negative association. When using a less intense stimulus like a bright spotlight, which is less aversive, more trials are needed. This indicates the effectiveness of aversive US in varied contexts and highlights how different intensities impact conditioning speed.

Key Concept: Schedules of Reinforcement

c) Continuous

[Solution Description] Continuous reinforcement occurs when a reward is given after every single correct response, leading to rapid learning.

Key Concept: Nonsense Syllables

a) Lists of nonsense syllables

[Solution Description] Nonsense syllables are often used in experiments of verbal learning to assess the meaningfulness of material. These syllable strings serve as a tool to study how associations and meaning can affect learning processes.

Key Concept: Stimulus Identification

a) ZUV

[Solution Description] In paired-associates learning, the stimulus is usually a nonsense syllable while the response is an English noun. In this case, ‘ZUV’ is the nonsense syllable, making it the stimulus term.

Key Concept: List Length

c) Learning time increases

[Solution Description] As the length of the list increases, the learning time also increases. This is because with more items in the list, it takes longer for an individual to learn and remember all the elements effectively.

Key Concept: Permanent vs. Temporary Change

b) Learning to ride a bicycle

[Solution Description] Learning to ride a bicycle is considered a relatively permanent change because, once learned, this skill remains with you for a long period and doesn’t diminish like temporary changes caused by fatigue or other factors.

Key Concept: Definition Recall

d) A relatively permanent change in behavior due to experience

[Solution Description] Learning is defined as a relatively permanent change in behavior due to experience. It differs from temporary changes such as those induced by fatigue or drugs which do not involve learning.

Key Concept: Extinction Process

b) Intermittent reinforcement

[Solution Description] Intermittent reinforcement tends to make learned behaviors more resistant to extinction compared to continuous reinforcement. This is because intermittent reinforcement creates a more unpredictable pattern, which makes it harder for the subject to detect when reinforcement has stopped, thus increasing the persistence of the behavior.

Key Concept: Phase Transition

c) Associative Phase

[Solution Description] In the associative phase of skill learning, attentional demands decrease as the learner becomes more familiar with the task and less conscious effort is required.

Key Concept: Feature Identification

b) Classical conditioning

[Solution Description] The syllabus mentions that classical conditioning was first investigated by Ivan P. Pavlov. This paradigm of learning involves associating an involuntary response with a new stimulus.

Key Concept: Sequence of Learning

c) Pre-test, processing, acquisition, recall

[Solution Description] The correct sequence of events in a standard learning experiment involves:

1. Pre-test: Assessing baseline knowledge.

2. Processing: Engaging with new information.

3. Acquisition: Learning new skills or knowledge.

4. Recall: Retrieving learned information.

Hence, the correct order is pre-test, processing, acquisition, recall.

Key Concept: Perceptual Disorders

b) Difficulty distinguishing between similar shapes such as ‘p’ and ‘q’

[Solution Description] A visual perceptual disorder may involve difficulty in recognizing or interpreting visual information, which is not due to problems with vision itself but rather how the brain processes visual input. Children might confuse similar symbols or letters like ‘p’ and ‘q’, as their brain misinterprets the visual cues.

Key Concept: Concept Identification

c) Issuing a fine for speeding on the highway

[Solution Description] Punishment involves introducing an unpleasant consequence to reduce a particular behavior. Taking away a privilege when a child misbehaves serves as a punishment since it intends to decrease the occurrence of that behavior.

Key Concept: Recall Order

d) Words at the beginning and end of the list

[Solution Description] In a free recall task, words at the beginning and end of the list are usually easier to recall due to the primacy and recency effects.

Key Concept: Real-world Application, Long-term Effects

b) Difficulty in maintaining employment due to ongoing literacy challenges.

[Solution Description] Dyslexia can lead to challenges that extend beyond academics if not addressed. The most significant long-term effects include difficulty in daily living activities due to persistent literacy challenges, potentially leading to issues in vocational settings. It may also affect self-esteem and social relations, as continuous struggles can impact confidence and communication skills.

Key Concept: Definition Recall

c) The ability to perform a complex task smoothly and efficiently

[Solution Description] A skill is defined as the ability to perform some complex task smoothly and efficiently.

Key Concept: Reinforcement and Extinction, Complex Reinforcement Scenarios

c) Moderate and steady response rate with high resistance to extinction

[Solution Description] In this scenario, the reinforcement follows after the first response after varying intervals of time. Here, the average interval is 2 minutes. Such a pattern of reinforcement is characterized as a Variable Interval (VI) schedule. It leads to moderate steady rates of responding and high resistance to extinction because the timing of reinforcement is unpredictable.

Key Concept: Critical Thinking, Hypothetical Analysis

b) Acquisition will speed up notably at higher intensities, while extinction may become more resistant due to strong conditioning.

[Solution Description] Gradually increasing the intensity of a conditioned stimulus could initially create slower acquisition as the subjects adjust to each new level of intensity. However, once the intensity reaches a significantly high level like 80 dB, the acquisition rate should accelerate due to the principles outlined in the syllabus. Regarding extinction, a highly intense stimulus might also prolong resistance to extinction due to stronger associations formed during acquisition.

Key Concept: Paired-Associates Basics

a) Stimulus

[Solution Description] In paired-associates learning, the first word serves as a stimulus that triggers a response. The participant must recall the second word in response to this stimulus.
