Morphological analysis by child readers as revealed by the fragment completion task

Area of Science:

• Developmental Psychology
• Psycholinguistics
• Cognitive Science

Background:

• Understanding how children process word forms is crucial for reading development.
• Morphological processing, the understanding of word structure, plays a key role in vocabulary acquisition and reading fluency.
• Previous research has explored various aspects of morphological awareness, but differentiating effects of form from meaning remains challenging.

Purpose of the Study:

• To investigate how ten-year-old children process morphologically related words.
• To examine whether children's performance on a fragment completion task is sensitive to morphological relationships.
• To differentiate morphological effects from effects of orthographic similarity in child readers.

Main Methods:

• Children completed word fragments (e.g., T_ _N) after being exposed to different study conditions.
• Study conditions included target words (identity), morphologically related words (transparent and opaque), and orthographically similar but unrelated words.
• A no-prime condition served as a baseline.

Main Results:

• Children's performance on the fragment completion task was significantly influenced by morphological relationships.
• Completion rates were higher for both transparent (e.g., TURNED-TURN) and opaque (e.g., RIDDEN-RIDE) morphological relatives compared to orthographically similar non-relatives (e.g., TURNIP).
• This suggests children utilize morphological information even when the relationship is not immediately obvious.

Conclusions:

• The fragment completion task is a valuable tool for studying morphological processing in children.
• This method effectively distinguishes morphological processing from simple form-based priming.
• Findings highlight the importance of morphological awareness in children's reading development.
