Skinner's Operant Conditioning
Skinner showed that it is the consequences of behaviour — reward or punishment — that decide whether that behaviour gets repeated. REET asks direct questions from this topic on types of reinforcement, schedules, and core terminology, all of which are also directly useful in classroom management.

How REET asks about this topic
The 2024 question was fill-in-the-blank type — asking what kind of analysis Skinner emphasised between behaviour and stimuli (answer: functional analysis). This shows that REET expects both precise terminology and clear definitions of Skinner's core concepts (operant conditioning, reinforcement, functional analysis).
What is Operant Conditioning
B.F. Skinner extended behaviourism by showing that it is the consequences of a behaviour that determine whether that behaviour will be repeated in the future. Through the 'Skinner box' (experiments on rats and pigeons), he showed that the outcome following an action — a reward or a punishment — changes the likelihood of that action being repeated. Skinner called this a 'functional analysis between behaviour and stimuli' — the study of how environmental conditions control behaviour.
Operant conditioning differs from Pavlov's classical conditioning in that in Pavlov's theory, the organism passively learns to respond to a stimulus (such as salivating on hearing a bell), whereas in operant conditioning, the organism actively operates on its environment and learns based on the consequences. This is exactly why Skinner's theory is the most practically applied of all in classroom management — most student behaviour (speaking up, raising a hand, doing homework) is operant in nature.
Types of reinforcement and punishment
| Type | Meaning | Example |
|---|---|---|
| Positive Reinforcement | Adding something pleasant right after a desired behaviour, which increases that behaviour | Praising or giving a star for good work |
| Negative Reinforcement | Removing something unpleasant after a desired behaviour, which increases that behaviour in future | Not assigning extra homework for finishing work on time |
| Positive Punishment | Adding something unpleasant after an undesired behaviour, which decreases that behaviour | Scolding a child for making noise |
| Negative Punishment | Removing something pleasant after an undesired behaviour, which decreases that behaviour | Taking away playground time |
In all four types, 'positive/negative' does not mean good/bad — it means 'adding something/removing something'[Source 1]
Schedules of Reinforcement
| Schedule | Meaning | Example |
|---|---|---|
| Fixed Ratio | Reinforcement given after a fixed number of responses, every single time | 1 star for every 10 correct answers |
| Variable Ratio | Reinforcement given after an unpredictable/varying number of responses — the most resistant to extinction | Winning at a slot machine, on an irregular basis |
| Fixed Interval | Reinforcement for the first correct response after a fixed time interval | A weekly test that happens every Monday |
| Variable Interval | Reinforcement after an unpredictable time interval — response rate is slow but steady | A surprise inspection at random times |
Points to note
- Shaping
- To teach a complex behaviour, successive approximations toward the desired behaviour are reinforced step by step, until the final behaviour is fully achieved
- Skinner box
- A device used for experiments on rats/pigeons, in which pressing a lever released food (reinforcement)[Source 1]
- Schedule most resistant to extinction
- Variable Ratio — because the uncertainty of whether the next response will be rewarded keeps the behaviour going[Source 1]
- Extinction
- When reinforcement is stopped entirely, the behaviour gradually decreases and eventually disappears
Classroom application
| Situation | What the teacher should do |
|---|---|
| Teaching a new behaviour (such as raising a hand before speaking) | Use shaping — reinforce small steps first with praise, then gradually build toward the full behaviour |
| Maintaining classroom discipline | Positive reinforcement (praise, star charts) is considered more effective and longer-lasting than punishment |
| Keeping students consistently interested and engaged | Unpredictable praise/rewards, like a variable ratio schedule, can sustain engagement over a longer period |
Points of caution when using reinforcement
When using reinforcement, teachers should keep the reward as close to the behaviour as possible (immediate reinforcement), since a delayed reward links less effectively to the behaviour. At the same time, over-reliance on external rewards (like repeated sweets or money) can weaken students' intrinsic motivation, so gradually shifting from external rewards to social reinforcement (praise, recognition) is considered the better strategy. Punishment should be used sparingly and carefully, because it only suppresses the unwanted behaviour — it does not teach a new, desired one.
REET often compares Skinner's theory with Pavlov's and Hull's — all three belong to the behaviourist tradition, but Pavlov focused on passive conditioning, Skinner on active, consequence-based learning, and Hull on a mathematical drive-reduction model. Keeping this distinction clear helps avoid the common REET mistake of attaching one theorist's concept to another.
REET candidates sometimes also see questions on 'continuous reinforcement', where every single correct response is reinforced without exception — this produces the fastest initial learning, but the behaviour also disappears fastest once reinforcement stops, unlike the four partial (intermittent) schedules described above. It helps to contrast this with those partial schedules: continuous reinforcement is best for teaching a brand-new behaviour quickly, while an intermittent schedule like variable ratio is best for maintaining a behaviour over the long run once it is established. A teacher who understands this difference can, for example, praise a shy student after every single instance of speaking up at first, and then gradually shift to praising only some instances once the student is comfortable, so the habit remains strong even without constant encouragement. REET occasionally frames this contrast directly, asking which schedule is best for introducing a brand-new classroom behaviour versus which is best for keeping an already-learned behaviour going over the rest of the year.

Trick to remember the schedules
Remember: 'Ratio = based on number, Interval = based on time.' And whatever is 'Variable' is always more unpredictable and more resistant to extinction — like a slot machine (variable ratio), which is why that kind of habit is the hardest to break.
REET 2024 solved question
Question 29
B.F. Skinner emphasized __________ between measurable behavior and stimuli to explain learning.
- Aआधारभूत विश्लेषण
- Bकार्यात्मक विश्लेषण
- Cमूलभूत विश्लेषण
- Dभाषा विश्लेषण
Explanation
बी.एफ. स्किनर (B.F. Skinner) ने अधिगम की व्याख्या के लिए मापनीय व्यवहार और उद्दीपकों/परिणामों के बीच कार्यात्मक विश्लेषण (Functional analysis) पर बल दिया, अर्थात यह देखना कि कौन-सी पर्यावरणीय परिस्थितियाँ और परिणाम किसी व्यवहार को नियंत्रित करते हैं। यही विचार आगे व्यवहार विश्लेषण (Behaviour analysis) का आधार बना।
Practice questions
Question 1
Who propounded operant conditioning?
- Aपावलव
- Bबी.एफ. स्किनर
- Cसिगमंड फ्रायड
- Dजीन पियाजे
Explanation
B.F. Skinner proposed operant conditioning, in which the consequences of behaviour determine whether it is repeated.
Question 2
Which of the following is a correct example of negative reinforcement?
- Aअच्छे काम पर तारीफ देना
- Bसमय पर गृहकार्य पूरा करने पर अतिरिक्त अभ्यास-कार्य न देना
- Cशोर मचाने पर डांटना
- Dखेल का समय हटा लेना
Explanation
Negative reinforcement increases a desired behaviour by removing something unpleasant (extra work), not by adding anything — it is not punishment.
Question 3
In which of the following reinforcement schedules is behaviour most resistant to extinction?
- Aनियत अनुपात
- Bनियत अंतराल
- Cपरिवर्ती अनुपात
- Dपरिवर्ती अंतराल
Explanation
In variable ratio schedules, the timing of the reward is uncertain, so the person keeps responding continuously, which makes it the most resistant to extinction.
Question 4
A weekly class test held every Monday is an example of which reinforcement schedule?
- Aपरिवर्ती अनुपात
- Bनियत अंतराल
- Cपरिवर्ती अंतराल
- Dनियत अनुपात
Explanation
An event that occurs at a fixed, regular time interval (every Monday) is an example of a fixed interval schedule.
Question 5
According to Skinner, what is the process of reinforcing successive approximations of a desired behaviour to teach complex behaviour called?
- Aशेपिंग (Shaping)
- Bविलोपन (Extinction)
- Cसामान्यीकरण (Generalization)
- Dविभेदीकरण (Discrimination)
Explanation
In shaping, a complex behaviour is broken into small steps, and every correct step is reinforced until the final behaviour is achieved.
Question 6
A teacher wants Class 3 children to develop the habit of quietly raising their hand before speaking. Based on Skinner's theory, what is the most suitable way to do this?
- Aबिना हाथ उठाए बोलने पर तुरंत कड़ा दंड देना
- Bहाथ उठाकर बोलने के हर प्रयास की तुरंत प्रशंसा करना
- Cव्यवहार पर कोई ध्यान न देना
- Dकेवल परीक्षा में अंक काटना
Explanation
Positive reinforcement (immediate praise) effectively increases the desired behaviour and also keeps the classroom atmosphere positive compared to punishment.
Question 7
Which creatures did Skinner mainly use in his experiments?
- Aबिल्ली और कुत्ते
- Bचूहे और कबूतर
- Cबंदर और गोरिल्ला
- Dमछली और पक्षी
Explanation
Skinner mainly used rats and pigeons in his experiments, conducted inside the 'Skinner box', where pressing a lever released food.
Question 8
According to Skinner, what is most important for explaining learning?
- Aव्यवहार व उद्दीपकों के बीच कार्यात्मक विश्लेषण
- Bअचेतन इच्छाएँ
- Cसंज्ञानात्मक संरचनाएँ
- Dसामाजिक अनुकरण
Explanation
Skinner emphasised a functional analysis between measurable behaviour and environmental stimuli/consequences, rather than internal mental processes.
Question 9
A student's noise-making behaviour in class is not decreasing even after being scolded by the teacher — in fact, the student seems to enjoy getting the teacher's attention. What could this be an example of?
- Aडांटना यहाँ अनजाने में सकारात्मक सुदृढीकरण का काम कर रहा है (ध्यान मिलना पुरस्कार जैसा लग रहा है)
- Bयह नकारात्मक दंड है
- Cयह विलोपन है
- Dयह शेपिंग है
Explanation
Sometimes even scolding becomes a reward in the form of 'attention' for a child, which unintentionally reinforces the unwanted behaviour — teachers need to stay alert to this.
Question 10
Which of the following is an example of a 'fixed ratio' schedule?
- Aहर 5 सही उत्तरों पर एक स्टिकर देना
- Bअनियमित समय पर औचक जाँच
- Cहर सोमवार परीक्षा
- Dकभी भी अनियमित रूप से इनाम देना
Explanation
Reinforcement given every time after a fixed number of responses (5 correct answers) is a fixed ratio schedule.
Frequently asked questions
What is operant conditioning?+
A learning process in which the consequences of a behaviour (reward/punishment) determine whether that behaviour is repeated in future; it was proposed by B.F. Skinner.
What is the difference between positive and negative reinforcement?+
Positive reinforcement adds something pleasant, while negative reinforcement removes something unpleasant — both increase the behaviour.
What is a Skinner box?+
A device Skinner built for experiments on rats/pigeons, in which pressing a lever released food, used to study the relationship between behaviour and its consequences.
What kind of questions does REET ask from Skinner's theory?+
Usually on types of reinforcement, identifying schedules, and Skinner's core terminology (such as functional analysis).
What is shaping, and what is the difference between operant conditioning and classical conditioning?+
Shaping is the process of reinforcing successive approximations toward a desired complex behaviour, step by step, until the final behaviour is achieved. In classical conditioning (Pavlov), the organism learns to respond passively, whereas in operant conditioning (Skinner), the organism actively acts on its environment and learns from the consequences.
