Introduction: Welcome to Learning Theories!
Ever wondered why you feel hungry as soon as you see a fast-food logo, or why you start working harder when you know there’s a reward at the end? That is exactly what Learning Theories are all about! In this chapter, we explore how our environment shapes who we are. Unlike other areas of psychology that look at your DNA or your thoughts, this section focuses on how we "learn" our behaviours through experiences, rewards, and watching others.
Don't worry if this seems like a lot to take in! We are going to break it down into simple, bite-sized pieces that will help you ace your Paper 2 exam.
1. Classical Conditioning: Learning by Association
Think of Classical Conditioning as "learning by accident" through association. It happens when two things occur at the same time, and our brain starts to link them together.
The Key Terms (The "Ingredients")
To understand this, you need to know these five terms. They look similar, but here is a simple trick: "Unconditioned" means natural/automatic, and "Conditioned" means learned.
• Unconditioned Stimulus (UCS): Something that naturally triggers a response (e.g., food).
• Unconditioned Response (UCR): The natural reaction (e.g., drooling at food).
• Neutral Stimulus (NS): Something that normally doesn't cause a reaction (e.g., a bell).
• Conditioned Stimulus (CS): What the NS becomes after learning (the bell now causes drooling).
• Conditioned Response (CR): The learned reaction to the CS (drooling at the bell).
The Famous Study: Pavlov (1927)
Ivan Pavlov noticed his dogs drooled not just at food, but at the sound of the lab assistant's footsteps! He tested this by ringing a bell (NS) before giving dogs food (UCS). Eventually, the dogs drooled (CR) just at the sound of the bell (CS).
Other Important Features
• Extinction: If you keep ringing the bell but never give food, the dog stops drooling. The link is broken.
• Spontaneous Recovery: After a break, if you ring the bell again, the dog might suddenly drool again. The memory isn't gone!
• Stimulus Generalisation: The dog might drool at sounds similar to the bell, like a telephone ringing.
Quick Review Box: Classical Conditioning = Association. If you see "Little Albert" or "Pavlov" in an exam, think about linking two things together!
2. Operant Conditioning: Learning by Consequences
This theory says we learn because of what happens after we do something. If the result is good, we do it again. If it's bad, we stop.
Reinforcement (Encouraging Behaviour)
• Positive Reinforcement: Giving a reward (e.g., getting £5 for cleaning your room).
• Negative Reinforcement: Taking away something unpleasant (e.g., putting on your seatbelt to stop that annoying "beeping" sound in the car). This is not punishment; it makes you feel better!
Punishment (Stopping Behaviour)
• Positive Punishment: Adding something bad (e.g., getting a detention).
• Negative Punishment: Taking away something good (e.g., having your phone taken away).
Key Properties and Shaping
• Primary Reinforcers: Things we naturally need (food, water).
• Secondary Reinforcers: Things we learn to want because they get us primary reinforcers (money, tokens).
• Shaping: Rewarding "baby steps" towards a difficult goal. For example, rewarding a dog for sitting, then for lying down, then for rolling over.
Common Mistake to Avoid: Many students think Negative Reinforcement is a punishment. It isn't! Reinforcement (Positive or Negative) always makes a behaviour more likely to happen again.
3. Social Learning Theory (SLT): Learning by Watching
Albert Bandura argued that we don't need to be rewarded personally to learn. We can learn just by observing a "model" (someone we look up to).
The Four Stages of SLT (Mnemonic: ARRM)
Imagine you are learning a new dance move from TikTok:
1. Attention: You have to notice the move.
2. Retention: You have to remember how they did it.
3. Reproduction: You have to be physically able to copy it.
4. Motivation: You have to want to do it (usually because you saw the TikToker get lots of likes).
Vicarious Reinforcement
This is a big term for a simple idea: Learning from someone else's reward. If you see your sibling get a chocolate bar for being quiet, you will be quiet too. You weren't rewarded, but they were!
Bandura's Bobo Doll Studies (1961, 1963, 1965)
Bandura showed children a film of an adult being aggressive to an inflatable "Bobo Doll."
• 1961/1963: Children who saw the aggressive model were much more likely to hit the doll themselves.
• 1965: If the child saw the adult being rewarded for the aggression, they copied it even more (Vicarious Reinforcement).
Key Takeaway: We copy people we identify with (models), especially if we see them getting rewarded.
4. Explaining and Treating Phobias
Psychologists use these theories to explain why some people are terrified of spiders or heights.
• Acquisition (Classical Conditioning): You might get a phobia if a dog (NS) bites you (UCS), causing pain (UCR). Now, dogs = fear (CR).
• Maintenance (Operant Conditioning): If you see a dog and run away, your anxiety goes down. This is Negative Reinforcement, which makes you more likely to avoid dogs in the future, keeping the phobia alive!
Treating Phobias: Systematic Desensitisation
This is a step-by-step treatment based on Classical Conditioning:
1. Functional Analysis: Talk about the fear.
2. Anxiety Hierarchy: Make a list from "least scary" (looking at a photo of a spider) to "most scary" (holding a spider).
3. Relaxation Training: Learning deep breathing techniques.
4. Gradual Exposure: Working through the list while staying relaxed. You cannot be relaxed and scared at the same time!
5. Research Methods in Learning Theories
How do we actually study this stuff? Psychologists use two main ways: watching people (Observations) and studying animals.
Observational Research
• Structured vs. Naturalistic: Using a pre-set list of behaviours to look for vs. just watching in a normal environment.
• Overt vs. Covert: Participants know they are being watched vs. the researcher is "undercover."
• Participant vs. Non-participant: The researcher joins in vs. stays separate.
• Tallying: Counting how many times a behaviour happens.
Animal Research and Ethics
Psychologists often use animals (like Pavlov’s dogs or Skinner’s rats) because they can control their environment perfectly. However, they must follow the Scientific Procedures Act (1986) and Home Office regulations. This ensures that animal suffering is kept to an absolute minimum and only used when necessary.
The Chi-Squared Test (\( \chi^2 \))
In this chapter, you might need to use the Chi-Squared statistical test. We use it when:
1. We are looking for a difference between groups.
2. The data is in categories (e.g., how many people said 'yes' vs 'no').
3. The design is independent groups (different people in each group).
The formula is: \( \chi^2 = \sum \frac{(o-e)^2}{e} \)
(Where 'o' is what you observed and 'e' is what you expected).
6. The Scientific Status of Psychology
The Learning Perspective is the most "scientific" part of Psychology. It focuses on:
• Replicability: Can we run the study again and get the same result? (Like Bandura's Bobo doll studies).
• Objectivity: Not using opinions, just facts.
• Empiricism: Only believing what we can actually see and measure.
• Falsification: A good theory must be able to be proven wrong.
• Reductionism: Breaking complex human behaviour down into simple "stimulus-response" links. While this is scientific, some critics say it’s too simple and misses the "human" element!
Key Takeaway: If a question asks if Psychology is a science, the Learning Theories are your best evidence to say "Yes!" because they use lab experiments and objective measures.
