Early word recognition in speech benefits infant vocabulary development. Later language skills may be linked through this early vocabulary size effect, not direct prediction.
Area of Science:
- Developmental Psychology
- Cognitive Neuroscience
- Linguistics
Background:
- Early word recognition in continuous speech is crucial for language development.
- Previous research suggests a long-term link between early speech segmentation skills and later language abilities.
Purpose of the Study:
- To further investigate the long-term relationship between early word recognition in speech and later language skills.
- To examine online processing and extended time spans in follow-up studies.
Main Methods:
- Two follow-up studies with infants who previously participated in speech segmentation tasks.
- Study 1 used a looking-while-listening task to assess online processing.
- Study 2 assessed language performance over a longer time span; a meta-analysis was conducted (Study 3).
Main Results:
- Speech segmentation ability at 10 months positively correlated with target fixations at 16 months (Study 1).
- Infant speech segmentation did not directly predict language profiles at age five (Study 2).
- Meta-analysis indicated age at follow-up did not moderate the effect size.
Conclusions:
- Infants' ability to recognize words in speech supports early vocabulary development.
- Later language skill relationships may stem from the established vocabulary size, not a direct link from early segmentation ability.

Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
