Syllabus: How Do We Learn From Other People?
Compare opaque and transparent boxes, the relevant and irrelevant actions, and the additional checks on causal knowledge. Keep copying fidelity distinct from efficient reward retrieval.
Why you’re reading it. Distinguish reproducing actions from learning about outcomes, while evaluating the limits of a species comparison.
A question to consider. How could the same unnecessary action indicate uncertainty in one learner and an attempt to follow a convention in another? Propose a comparison that would help tell them apart.
Why this reading
Reproducing a demonstrated action and obtaining the same result are different achievements. This comparative study makes the difference experimentally useful by changing how clearly a puzzle box reveals which actions can affect its reward.
Before you read
Imitation refers here to copying aspects of the demonstrated actions; emulation concerns learning about results or environmental relations and reaching the outcome through one’s own actions. A causally irrelevant action does not contribute mechanically to retrieving the reward in this apparatus. That does not make it meaningless to a learner interpreting a social demonstration.
Read for
- Track the opaque and transparent versions of the box, presentation order, and the relevant and irrelevant parts of each demonstrated sequence.
- Separate matching an action’s detailed form from reproducing a broader sequence. Follow the additional chimpanzee tasks that examine understanding of the tool and barrier.
- Compare the child and chimpanzee procedures, rearing histories, rewards, and testing contexts before interpreting a species difference.
Consider afterwards
- Children copy an unnecessary step in a transparent apparatus. Design a comparison that could help distinguish uncertainty about its causal role from treating the demonstration as a convention to follow.
Editorial context
The main comparison uses small, specific samples: sanctuary chimpanzees and 16 nursery-school children. The authors discuss several explanations for the children’s copying, including attention and interpretation of the demonstrator’s intentions. Efficiency in retrieving one reward is not a general ranking of intelligence, and the pattern is not evidence that children lack causal knowledge. Lyons and colleagues (2007) offer further experiments and an account of how unnecessary actions enter children’s causal representations; that explanation also requires scrutiny.
