Origins of Psychology

Back in 1879, Wilhelm Wundt opened the first psychology lab in Germany and basically invented psychology as we know it. His big idea was to study human consciousness (how our minds work) in a controlled, scientific way rather than just philosophising about it.

Wundt pioneered introspection - getting people to carefully observe and report their own thoughts and feelings. His participants would listen to a ticking metronome and describe exactly what was going on in their minds, which he'd record systematically.

This approach helped identify the basic building blocks of consciousness like thoughts, images, and sensations. Most importantly, it separated psychology from philosophy and made it a proper science for the first time.

Key Point: Wundt's work in 1879 marks the birth of scientific psychology, moving it away from pure philosophy into controlled laboratory research.

Psychology Becomes Scientific

The early 1900s saw major changes as behaviourists like Watson rejected introspection completely. They argued it was too subjective - basically just people's personal opinions rather than hard facts that could be measured and tested.

By the 1930s, Skinner's behaviourist approach dominated psychology for 50 years. These researchers insisted that 'proper' psychology should only study things you can actually observe and measure, bringing the rigour of natural sciences into psychology.

The 1950s brought the cognitive revolution after computers were invented. Psychologists realised they could study mental processes scientifically by comparing the mind to a computer and testing predictions about memory and attention.

From the 1980s onwards, the biological approach took off thanks to brain scanning technology like fMRI and EEG, plus advances in genetic research that helped us understand how genes influence behaviour.

Remember: Each decade brought new scientific methods - from controlled labs to computer models to brain scans.

Evaluating Early Psychology

Wundt's contributions were massive - he created the first psychology journal, wrote the first textbook, and earned the title 'father of modern psychology'. His controlled laboratory methods and standardised procedures laid the foundation for all the scientific approaches that followed.

Modern psychology definitely counts as scientific because it shares the same goals as natural sciences: describing, understanding, predicting, and controlling behaviour. Most approaches use proper scientific methods like controlled experiments to establish cause and effect.

However, introspection had serious flaws. People reporting their private thoughts is incredibly subjective - they might lie, forget, or simply not understand what's happening in their own minds. This makes it impossible to create reliable 'laws of behaviour'.

Not all psychology approaches are scientific anyway. The humanistic approach deliberately avoids trying to create general laws, focusing instead on unique personal experiences that can't be measured objectively.

Exam Tip: You can argue both sides - psychology has scientific elements but also non-scientific approaches depending on what's being studied.

The Behaviourist Approach

Behaviourists only cared about observable, measurable behaviour - they completely ignored mental processes and treated the mind like a 'blank slate' that gets written on by experience. Everything we do is learned through our environment.

Classical conditioning is learning through association. Pavlov famously showed this by getting dogs to salivate when they heard a bell. He paired the bell (neutral stimulus) with food (unconditioned stimulus) repeatedly until the bell alone made them drool.

The process works in three stages: before conditioning (food causes salivation, bell doesn't), during conditioning $bell + food presented together$, and after conditioning (bell alone causes salivation because it's now a conditioned stimulus).

Operant conditioning shapes behaviour through consequences. Positive reinforcement adds something pleasant, negative reinforcement removes something unpleasant (both increase behaviour), while punishment adds something unpleasant to decrease behaviour.

Memory Trick: Think of your phone - you keep checking it because of positive reinforcement (likes, messages) and negative reinforcement $stopping boredom/anxiety$.

Testing Operant Conditioning

Skinner's experiments used specially designed cages (Skinner boxes) with rats and pigeons. Every time animals pressed a lever or pecked a disc, they got food pellets - showing how pleasant consequences increase behaviour repetition.

He also demonstrated negative reinforcement by training animals to perform behaviours that stopped electric shocks. This proved that removing unpleasant things is just as powerful as adding pleasant ones.

The behaviourist approach gave psychology scientific credibility by focusing on careful measurement in controlled conditions. Breaking behaviour down into stimulus-response units and studying cause-and-effect relationships brought proper scientific methods into psychology.

Real-world applications include token economy systems used in prisons and psychiatric wards, where people earn tokens for good behaviour that can be exchanged for privileges - proving these principles actually work in practice.

Think About It: You probably use operant conditioning daily - rewarding yourself after studying or avoiding behaviours that led to bad consequences before.

Problems with Behaviourism

Behaviourism presents a mechanistic view that treats humans like passive machines responding to their environment. This ignores the active role our minds play in learning - we're not just robots reacting to stimuli.

It's also environmental determinism - claiming all behaviour comes from past conditioning and ignoring free will completely. Skinner argued free will is just an illusion, but this extreme position doesn't account for conscious decision-making.

Animal research raises ethical issues since animals were kept in harsh conditions, deliberately underfed to stay motivated by food rewards. While the research produced valuable insights, there are serious questions about whether the benefits justify the animal suffering.

Other approaches like Social Learning Theory and the cognitive approach have shown that mental processes during learning are crucial - we're much more active participants in our own learning than behaviourists suggested.

Critical Thinking: Consider whether the knowledge gained from animal experiments justifies the ethical costs - this debate continues in psychology today.

Social Learning Theory

Social Learning Theory bridges behaviourism and cognitive approaches by recognising that we learn through observation, but mediational processes (mental factors) determine whether we actually copy what we see.

The four mediational processes are crucial: Attention (we must notice the behaviour), Retention (we must remember it), Reproduction (we must be physically able to copy it), and Motivation (the rewards must seem worth it).

Vicarious reinforcement means we observe what happens to others and copy behaviours that get rewarded while avoiding those that get punished. We don't need to experience consequences directly - we learn from watching others.

Identification explains why we're more likely to imitate people we see as similar to ourselves or who have high status and attractiveness. These role models have more influence on our behaviour than random strangers.

Real Example: You might copy a popular student's study habits if you see them getting good grades, especially if you identify with them in some way.

Bandura's Bobo Doll Studies

Bandura's first study showed children different adult behaviours with a Bobo doll - some saw aggression, others saw non-aggressive play. When given their own doll, children who witnessed aggression were much more aggressive themselves.

His second study explored vicarious reinforcement by showing children adults who were either rewarded, punished, or experienced no consequences for aggressive behaviour. Children who saw aggression rewarded were most likely to copy it.

These studies proved that children learn violence through observation and are more likely to imitate aggressive behaviour if they see it being rewarded. This has huge implications for understanding media influence on behaviour.

The research demonstrates how imitation works in practice - we don't just copy any behaviour we see, but we're influenced by the consequences others experience and whether we identify with the person we're observing.

Modern Relevance: These findings are still used today in debates about violent video games, films, and social media influence on young people's behaviour.

Evaluating Social Learning Theory

SLT emphasises cognitive factors that behaviourism completely ignored. Neither classical nor operant conditioning alone can explain human learning because they miss out mental processes - we store information about others' behaviour and make judgements about when to use it.

The theory has excellent real-world applications for understanding how children learn gender roles, cultural norms, and behaviours through media influence. It explains how knowledge and behaviours spread through society via observation and imitation.

SLT is less deterministic than pure behaviourism because it recognises we have some choice in what we pay attention to, remember, and decide to imitate. We're active participants rather than passive recipients of conditioning.

However, the theory still doesn't fully account for individual differences - why do people exposed to the same models sometimes learn completely different things? Personal factors like personality and existing beliefs play important roles too.

Exam Success: Remember that SLT provides a bridge between behaviourist and cognitive approaches, combining the best elements of both while addressing their individual weaknesses.
