Learning theory and language development
Apply observation, imitation, positive and negative reinforcement to language learning and interpret Goldstein and colleagues’ findings.
Original teaching mapped to Cambridge IGCSE Psychology 0266 Version 3 for 2027–2029. The course is independent study support, not Cambridge material, an official mark scheme or an awarded grade. Named-study notes summarise the required findings; candidates are not expected to evaluate named studies. Self-check practice is not official grading, a timed Paper 1/2 simulator or teacher review.
Before you begin
- Use the Version 3 syllabus and confirm availability in your administrative zone with Cambridge and your school. Both papers are compulsory. The updated named-study summaries are required context; full original research articles are not required.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Before learning theory and language development, which approach is most useful?
What you will learn
- Explain observation, imitation and positive/negative reinforcement
- Apply learning theory to speech development
- Use Goldstein et al.’s social-feedback study
- Explain novel child language as a counterargument
Children can learn language through social experience
Learning theory proposes that children observe and imitate speech, then receive feedback. Positive reinforcement adds a pleasant response after a behaviour; negative reinforcement removes an unpleasant stimulus to increase the behaviour. Negative reinforcement is not punishment.
Named study: Goldstein and colleagues
Mothers of 30 infants aged 8–10 months were observed during play. In one condition mothers responded warmly immediately after vocalisations; a comparison group received response instructions not tied to the child’s sounds. Infants in the contingent-response group made more and more advanced vocalisations than at baseline and than controls. This supports social feedback as a contributor to speech development.
Children also create new language
Young children use novel word combinations and grammatical forms they have not simply copied. That is the syllabus counterargument: imitation and reinforcement alone may not explain all language development.
Pause and explain
Which response best shows understanding of learning theory and language development?
Worked example
An adult smiles and moves closer each time an infant makes a new speech sound, and the sound becomes more frequent. Explain the learning process.
Show the worked solution
- The social response follows the vocalisation.
- The response is pleasant and contingent.
- It can act as positive reinforcement.
Answer The contingent social response can positively reinforce vocalisation.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A toddler says a word and a caregiver smiles immediately; the toddler repeats it more often. Identify the learning process.
Give me a hint
A positive response follows the speech.
Compare my reasoning
- The caregiver’s smile follows the word.
- The smile is pleasant feedback.
- It can positively reinforce the word use.
Positive reinforcement.
Look for these in your work
- Identifies the response
- Notes its timing
- Explains the increase
What did Goldstein et al. find when mothers’ responses followed infants’ vocalisations?
Give me a hint
Compare vocalisation number and quality.
Compare my reasoning
- The study compared contingent social response with a non-contingent schedule.
- The contingent group showed more and more advanced vocalisations.
- The result supports a role for social feedback.
Infants receiving contingent responses vocalised more and at a more advanced level.
Look for these in your work
- States the design contrast
- Reports both outcomes
- Links to learning theory
A child says ‘I goed’ even though adults around them say ‘I went’. What challenge does this create for a strict imitation account?
Give me a hint
The child produces a form not copied from the model.
Compare my reasoning
- The child used a grammatical form heard less or not at all.
- The word appears to be constructed by the learner.
- Novel language suggests imitation and reinforcement do not explain every feature.
The child’s novel form challenges an account based only on copying and feedback.
Look for these in your work
- Notes the novel form
- Contrasts with the model
- States the limitation
Common mistakes
- Calling negative reinforcement punishment.
- Saying the study tested animal language knowledge for learners.
- Ignoring novel language as evidence against imitation-only accounts.
What can you explain now?
What is negative reinforcement?
Compare with the explanation
Removing an unpleasant stimulus to increase a behaviour
It increases behaviour by removing something unpleasant; punishment aims to reduce behaviour.

Make it stick
How do observation and reinforcement support language learning, and why do novel child utterances matter?
