Syllabus: How Do Children Develop Language and Thought?
Move from interpreting a word to extending a linguistic pattern. Compare what a novel-word response reveals with what Tomasello’s word-learning examples reveal; neither task provides a complete account of language acquisition.
A question to consider. How would you use unfamiliar words with different sound patterns to investigate the scope of a child’s generalization rather than simply record a correct answer?
Why this reading
Repeating a familiar word cannot show whether a child can extend a pattern to something new. Berko’s invented-word tasks make that distinction concrete. The paper examines what children can produce beyond memorized forms and shows that generalization can be systematic while remaining incomplete.
Before you read
Morphology concerns the structure of words. Inflection changes a word to express features such as number or tense; derivation creates a new word. An allomorph is a different spoken form of the same meaningful element, such as the different sounds of the English plural ending. A novel-word task tests a response to a form the participant has not previously learned.
Read for
- Explain how invented words distinguish generalization from reproduction of a familiar form. Which aspects of a child’s response still depend on prior language experience?
- Compare the patterns across plural, possessive, and verb endings. Attend to the sound environments and the uneven success rather than reducing the results to one famous example.
- Examine the age groups, adult comparison, and elicitation procedure. Distinguish evidence for productive knowledge from evidence about how that knowledge was acquired.
Consider afterwards
- A child produces an appropriate ending for one invented noun but fails on another with a different final sound. What follow-up items would help distinguish a limitation in the learned pattern from a pronunciation or task difficulty?
Editorial context
The study established a powerful way to investigate productive linguistic knowledge. Novel-word generalization does not by itself decide among every rule-based, analogy-based, or usage-based explanation. The findings concern particular English patterns in a limited sample, not a universal timetable for grammar. Cross-sectional age differences do not show an individual child’s learning trajectory. The paper’s historical speculation about intelligence or sex differences should be distinguished from what its comparisons actually establish.
