Understanding Criminal Behaviour Through Social Learning Theory

Why do some people turn to crime while others, raised in similar circumstances, follow the rules? The answer isn’t always found in biology or personality. According to the social learning approach, criminal behaviour is something people pick up from their environment – through watching, imitating, and being rewarded for certain actions. This perspective, rooted in forensic psychology, argues that crime is not born into a person but learned, much like any other social behaviour. Let’s break down how this works, who proposed it, and why it matters for understanding the criminal mind.

What is the social learning approach to criminal behaviour? 🔗

The social learning approach is built on a straightforward premise: people learn how to behave by observing others. When applied to criminal behaviour, this means individuals can acquire antisocial or illegal behaviours by watching people around them – family members, friends, peers, or even media figures – engage in those behaviours. If those actions appear to be rewarded or go unpunished, the observer is more likely to adopt them.

This idea stands apart from biological theories that focus on genetics or brain chemistry. Instead, it places the social environment at the centre of why people commit crimes. According to social learning theory as applied in criminology, individuals learn behaviours, attitudes, and the expected consequences of those behaviours from the people in their social circles. The theory also suggests that if these behaviours can be learned, they can potentially be unlearned – which has significant implications for rehabilitation.

Cornell Montgomery’s stages of social learning 🔗

Cornell Montgomery, a key contributor to the social learning framework in criminology, proposed that learning criminal behaviour is not an overnight event. It unfolds gradually through a series of identifiable stages. Each stage builds on the previous one, slowly drawing an individual deeper into criminal patterns of behaviour.

Stage 1: Close contact 🔗

The process begins with close contact with individuals who already engage in criminal activities. This could be a child growing up in a household where substance abuse is normalised, or a teenager spending time with a peer group involved in petty theft. The key factor here is proximity and frequency of exposure. The more regularly a person is around criminal behaviour, the more familiar and normal it begins to seem. This stage doesn’t require active participation – simply witnessing or hearing about criminal acts repeatedly is enough to begin the learning process.

Stage 2: Imitation of superiors 🔗

Once close contact is established, the individual begins to imitate the behaviour of role models or superiors. In the context of criminal behaviour, a “superior” can be anyone the individual looks up to – a parent, an older sibling, a gang leader, or a respected peer. The person doesn’t just copy the actions; they also start absorbing the attitudes and justifications behind those actions. For example, a teenager who watches a friend shoplift successfully and face no consequences may decide to try it themselves, seeing the behaviour as both low-risk and socially acceptable within their group.

As research in forensic psychology notes, people are especially likely to model the behaviour of someone they perceive as similar to themselves or someone who appears to gain status or rewards from their actions.

Stage 3: Understanding of concepts 🔗

At this stage, the individual moves beyond mere imitation and develops a deeper understanding of criminal concepts. This includes learning the rationalizations and justifications that criminals use to explain their behaviour. A person might begin telling themselves things like “everyone does it” or “they can afford to lose it” as a way of making peace with criminal acts. This cognitive shift is crucial – it transforms criminal behaviour from something foreign into something that feels personally justified.

This stage aligns closely with what criminologists call definitions favourable to crime. According to sociological theories of crime causation, some people conditionally approve of certain criminal acts, believing that while crime is generally wrong, it becomes acceptable under specific circumstances.

Stage 4: Role model behaviour 🔗

The final stage is where criminal behaviour becomes ingrained as part of the individual’s identity. The person no longer sees criminal acts as occasional or situational – they view themselves as part of a criminal subculture. At this point, the learned behaviours are deeply internalised, and the individual may actively serve as a role model for others, perpetuating the cycle of social learning. Positive reinforcement – such as financial gain, peer approval, or the thrill of evading punishment – cements these behaviours further. Over time, crime becomes not just a choice but a way of life.

The role of reinforcement in criminal behaviour 🔗

One of the most powerful mechanisms in the social learning approach is reinforcement. Whether a learned behaviour persists or fades depends largely on the consequences it produces. This applies to criminal behaviour just as it does to any other kind of behaviour.

Positive reinforcement 🔗

When criminal behaviour leads to a desirable outcome, that outcome acts as positive reinforcement. The rewards can take many forms – money from a robbery, social status from gang involvement, the adrenaline rush of getting away with something, or even peer approval. As research from Penn State’s applied social psychology program highlights, these favourable outcomes – whether financial, emotional, or social – cause the behaviour to be repeated because the individual has learned that their actions produce the results they want.

Negative reinforcement 🔗

Negative reinforcement also plays a role, though it works differently. Here, criminal behaviour is reinforced because it removes something unpleasant. For instance, a person who joins a gang to escape bullying has their violent or antisocial behaviour negatively reinforced – the bullying stops, which encourages them to continue the behaviour that led to that relief. Similarly, a young person who steals food because they’re hungry finds the behaviour reinforced because it removes the discomfort of hunger.

Vicarious reinforcement 🔗

An important extension of reinforcement in social learning theory is vicarious reinforcement – the idea that people don’t need to experience rewards or punishments directly. They can learn simply by observing what happens to others. If a teenager sees a peer gain respect and money through drug dealing, they may be motivated to imitate that behaviour even without having tried it themselves. Albert Bandura’s foundational work on observational learning demonstrated this clearly: individuals can acquire new behaviours purely by watching others and noting the consequences those others face.

Julian Rotter’s contribution: expectancy and reinforcement value 🔗

While Cornell Montgomery outlined the stages of social learning, American psychologist Julian Rotter added a more nuanced layer to the theory by focusing on the cognitive side of decision-making. Rotter’s social learning theory, first published in his 1954 work Social Learning and Clinical Psychology, introduced the idea that behaviour isn’t just a product of observation and imitation – it’s also shaped by what people expect to happen and how much they value the expected outcome.

The predictive formula: BP = f(E & RV) 🔗

Rotter proposed a formula to predict behaviour: Behaviour Potential = function of (Expectancy × Reinforcement Value). In plain terms, the likelihood that someone will engage in a specific behaviour depends on two things – how strongly they believe the behaviour will lead to a particular outcome (expectancy), and how desirable that outcome is to them (reinforcement value). According to Cal State Fullerton’s overview of Rotter’s theory, if both expectancy and reinforcement value are high, the person is very likely to perform the behaviour. If either one is low, the behaviour becomes less likely.

Applied to criminal behaviour, this means a person is most likely to commit a crime when they believe the crime will succeed (high expectancy) and the reward is something they strongly desire (high reinforcement value). A burglar who has successfully robbed houses before and knows there’s valuable property inside a target home has both high expectancy and high reinforcement value – making the criminal act highly probable.

The psychological situation 🔗

Rotter also stressed the importance of the psychological situation – the idea that every person interprets the same environment differently. Two individuals standing in front of the same unlocked car will have different thoughts, different expectancies, and different reinforcement values based on their personal histories and social learning. This subjective interpretation of the environment, as noted in published research on Rotter’s framework, is what ultimately drives behaviour rather than any objective set of stimuli.

Locus of control 🔗

Perhaps Rotter’s most well-known contribution is the concept of locus of control. This refers to the degree to which a person believes they control the outcomes in their life. People with an internal locus of control believe their actions directly influence what happens to them. Those with an external locus of control tend to believe that outcomes are determined by luck, fate, or powerful others. Research suggests that individuals with a strong external locus of control may be more susceptible to criminal behaviour because they feel less personal responsibility for their actions and may attribute their circumstances to forces beyond their control.

How observation and imitation shape criminal behaviour: real-world examples 🔗

The social learning approach isn’t just theoretical. There is substantial real-world evidence supporting its claims.

Domestic violence cycles: Children who grow up witnessing domestic violence are significantly more likely to be involved in domestic violence as adults. They observe the behaviour, see the power dynamics involved, and may come to view violence as a normal or effective way to handle conflict. This is a textbook example of observational learning leading to the reproduction of harmful behaviour.

Substance abuse patterns: Children raised in homes with substance abuse are considerably more likely to develop substance use problems themselves. They observe the behaviour, understand how substances are used, and may even receive implicit or explicit encouragement to participate.

Peer influence on juvenile crime: As an open criminology textbook from Kwantlen Polytechnic University notes, association with peers who engage in crime is one of the strongest predictors of juvenile delinquency. Within peer groups, individuals observe criminal behaviour, receive reinforcement for participating, and gradually develop attitudes that justify continued offending.

Gang recruitment: Gangs often function as powerful social learning environments. New members observe established members gaining money, respect, and protection. These observations, combined with direct reinforcement for participating in gang activities, create a strong pull toward criminal behaviour.

Strengths and limitations of the social learning approach 🔗

Strengths 🔗

The social learning approach offers a compelling explanation for why criminal behaviour often runs in families and peer groups. It accounts for environmental influence in a way that purely biological theories cannot. It also provides a foundation for intervention – if criminal behaviour is learned, it can theoretically be unlearned through exposure to positive role models and prosocial reinforcement. Many correctional rehabilitation programmes are grounded in social learning principles, focusing on replacing criminal thinking patterns with more adaptive beliefs and behaviours.

Limitations 🔗

However, the theory has notable weaknesses. It struggles to explain crimes that seem to occur without prior observation – for example, a first-time murderer who has never witnessed homicide. It also tends to focus heavily on environmental factors while underplaying biological and genetic influences on behaviour. Additionally, much of the experimental evidence (such as Bandura’s famous Bobo doll studies) demonstrates only short-term effects, raising questions about whether observed aggressive behaviour translates into sustained criminal activity over time.

The theory also doesn’t fully explain individual differences. Two siblings can grow up in the same household with the same exposure to criminal behaviour, yet one may become a criminal while the other does not. This suggests that social learning is an important piece of the puzzle but not the entire picture.

Why the social learning approach matters in forensic psychology 🔗

For forensic psychologists, the social learning approach provides a practical framework for understanding how criminal behaviour develops and, crucially, how it might be changed. By identifying the specific social influences, reinforcement patterns, and cognitive expectations that drive a person’s criminal behaviour, forensic professionals can design targeted interventions. Whether it’s restructuring a juvenile offender’s peer environment, teaching alternative coping strategies, or addressing the rationalizations that sustain criminal thinking, social learning principles remain at the heart of modern evidence-based criminal rehabilitation.

The approach also has value in prevention. Understanding that criminal behaviour is learned through observation and reinforcement highlights the importance of early intervention – providing at-risk youth with positive role models, structured environments, and reinforcement for prosocial behaviour before criminal patterns become entrenched.

What do you think? Can changing a person’s social environment truly override years of learned criminal behaviour? And where do you draw the line between personal responsibility and the influence of one’s surroundings?
