Study Notes
Language Development in Children
- The frequency of questions increases as children age, indicating a growing ability to seek information and engage in conversation.
Early Language Development Strategies
- Very young children often use a strategy called "holophrastic" response, where they respond to speech with a single word or phrase.
Passive Forms in Children's Speech
- Passive forms start to occur in children's speech around 2-3 years of age, marking a significant milestone in language development.
Measuring Language Development
- Mean Length of Utterance (MLU) measures the average length of a child's sentences, providing a quantitative indicator of language development.
Development of Complex Sentences
- The frequency of complex sentences increases as children develop, indicating a growing ability to convey complex ideas and relationships.
Brown's Longitudinal Study on Morphological Development
- Brown's study found that children acquire grammatical morphemes in a specific order, with the earliest morphemes being present, progressive, and prepositions, and the latest being third-person singular present.
Acquisition of Grammatical Morphemes
- The researcher implies that children acquire grammatical morphemes in English through a gradual and predictable process, with certain morphemes emerging earlier than others.
Characteristics of Declaratives
- Declaratives in children's language development are characterized by a gradual increase in complexity, with children initially using simple declaratives and eventually moving to more complex forms.
Significance of Morpheme Acquisition Order
- The order in which children acquire different morphemes is significant, as it suggests a universal and innate linguistic ability that guides language development.
Use of Imperatives in Early Language Development
- The rarity of imperatives in early language development, as observed in Brown's study, suggests that children initially focus on declarative sentences and only later develop the ability to use imperatives effectively.

Description
Explore the morphological development in children through Brown's (1973) longitudinal study tracking the appearance of grammatical morphemes in English. Discover the time it takes for different morphemes to become reliably used and the long period between their first appearance and reliable usage.
