What this dot point is asking
Watson and Rayner (1920), the Little Albert study, is the classic research evidence for the behaviourist approach in Component 1. You must know its aim, method, results and conclusions, evaluate it, and explain how it supports the behaviourist assumption that emotional responses are learned through classical conditioning.
The answer
Aim and method
Results and conclusions
Evaluation
- Control. A clear baseline and standardised procedure give high internal validity and replicability.
- Theoretical and applied value. Strong support for classical conditioning, with applications to understanding and treating phobias.
- Single case. One infant, so the findings may not generalise.
- Serious ethical issues. A baby was deliberately frightened, could not consent, and (per the study) the fear was not removed before he left, risking lasting harm.
- Disputed generalisation. Some later analyses question how strong or consistent the generalisation really was.
Examples in context
Example 1. Why this anchors the behaviourist approach. The study is a direct demonstration of the behaviourist assumption that behaviour, including emotion, is learned from the environment by association. Albert was effectively a "blank slate" who acquired a fear through conditioning, which is why Eduqas uses it as the classic evidence for the behaviourist approach.
Example 2. The link to treating phobias. If a phobia is a conditioned association, it can be unlearned by counterconditioning, which is the logic of systematic desensitisation. Little Albert therefore connects to the behaviourist therapy and to the Component 3 work on modifying behaviour, showing how the same principle explains and treats a problem.
Try this
Q1. Identify the unconditioned stimulus in the Little Albert study. [1 mark]
- Cue. The loud noise made by striking the steel bar, which naturally produced fear.
Q2. Explain what is meant by generalisation in this study. [2 marks]
- Cue. Albert's conditioned fear spread from the rat to other similar white, furry objects (a rabbit, a dog, a fur coat), so the fear response was triggered by stimuli resembling the original.
Q3. State one ethical issue raised by the study. [2 marks]
- Cue. A baby was deliberately made fearful and could not consent, and the fear reportedly was not removed before he left, risking lasting psychological harm.

A description item testing method and results (AO1).
Method: a controlled observation (a single-participant case study) on an infant, "Little Albert", aged about 11 months. First Albert was shown a white rat and showed no fear (the neutral stimulus). Then, each time he reached for the rat, the researchers struck a steel bar with a hammer behind his head, producing a loud noise (the unconditioned stimulus) that frightened him (the unconditioned response). This pairing was repeated several times.
Results: after conditioning, Albert showed fear (crying, avoidance) at the sight of the rat alone, which had become a conditioned stimulus producing a conditioned fear response. The fear generalised to other white, furry stimuli (a rabbit, a dog, a fur coat, cotton wool and a Santa mask).
Markers reward the neutral-stimulus baseline, the pairing of the rat with the loud noise, the conditioned fear of the rat, and the generalisation to similar stimuli.

A balanced evaluation (AO3) reaching a judgement.
Strengths: it was highly controlled, with a clear baseline and standardised procedure, allowing the demonstration that an emotional response can be conditioned (high internal validity and replicability); and it provided strong support for classical conditioning as an explanation of learned emotion, with real applications (for example understanding and treating phobias).
Weaknesses: it is a single case study, so the findings may not generalise to other infants; and it raises serious ethical issues - a baby was deliberately made fearful, could not consent, and (according to the study) the fear was not removed before he left, causing potential lasting harm. Whether the fear truly generalised has also been questioned.
A strong answer concludes that the study is a powerful, well-controlled demonstration of conditioned emotion but is ethically unacceptable by modern standards and limited by its single case. Markers reward developed points with a judgement.
