Syllabus: How Do Infants Build Knowledge and Skills?
Use the proposed systems to formulate claims that go beyond a single task. Bring Aslin’s question about measurement to the argument from recurring signatures across ages, tasks, and species.
A question to consider. Choose one proposed system. What pattern across two different tasks would strengthen the account, and what pattern would force it to change?
Why this reading
What resources could make later learning possible? Spelke and Kinzler propose a small set of systems for representing objects, agents, number, and space. Their framework invites readers to consider how recurring limits, as well as successes, can identify a proposed cognitive system.
Before you read
A representation carries information about something beyond the immediate response. A domain is a class of problems or entities, such as objects or number. A signature limit is a characteristic failure or constraint that a theory predicts across tasks. Early emergence, continuity across ages, and evolutionary history are distinct kinds of evidence.
Read for
- For one proposed system, identify its organizing principles and characteristic limits. What would count against grouping the findings together?
- Examine how the argument moves among infants, adults, other species, and different communities. What inference does each comparison support?
- Distinguish the four principal systems from the more tentative proposal about social partners. Track what the theory leaves for subsequent learning and conceptual change.
Consider afterwards
- Two tasks produce the same limit on the number of objects tracked. What further evidence would help decide whether they rely on one system or merely place similar demands on attention?
Editorial context
This is a theoretical synthesis, not a direct demonstration of the origins of every capacity it discusses. A response found early in life does not by itself identify what was learned, inherited, or assembled through development. The proposed systems and their boundaries are claims to evaluate. The article’s social-group proposal is tentative; a looking preference should not be treated as a complete account of social attitudes or moral judgment.
