Sensitivity to Meaningful Morphological Information Acquired through Reading Experience Data Collections, 2022-2025

The data collection comprises three elements that link properties of the words that occur in books suitable for children and young people to the morpheme knowledge that readers display in reading tasks. These three elements include the following:

(a) A lexical database of the words that occur in 1200 books suitable for children and young people aged 7-16. This database comprises over 100,000 words and a range of psycholinguistic properties such as word frequency and contextual diversity. The corpus from which these words were sourced contains over 70 million words.

(b) A computational algorithm that parses these words into morphemes and provides data about their frequency of occurrence. Notably, the parser works on morphemes defined orthographically (as opposed to etymologically) and so captures what a child might learn about morphology through reading experience.

(c) Response time and accuracy data from a large-scale study of human readers that links the corpus-based metrics pertaining to morphemes to reading performance.

Each of these datasets, along with relevant pre-processing and analysis code, is available on the Open Science Framework (OSF). Each of these OSF projects also contains comprehensive documentation to facilitate reuse. Links are available as related resources.
