Child-directed speech (CDS) with sentence frames helps infants recognize words faster than isolated words. Familiar phrases aid young children
Area of Science:
- Developmental Psychology
- Linguistics
- Cognitive Science
Background:
- Child-directed speech (CDS) often features short utterances and isolated words.
- The impact of these features on infant word recognition is debated.
- Some theories suggest isolated words aid segmentation, while others predict no benefit.
Purpose of the Study:
- To investigate whether sentence frames in CDS enhance infant word recognition.
- To directly test the perceptual advantages of specific CDS structures.
Main Methods:
- Utilized a looking-while-listening procedure with 18-month-old infants.
- Presented familiar object names in isolation and within a sentence frame.
- Measured online speech processing using reaction times.
Main Results:
- Infants were 120 ms slower to interpret words presented in isolation.
- Word recognition was facilitated when words were preceded by a familiar carrier phrase.
- Sentence frames appear to aid infants in processing target words.
Conclusions:
- Familiar sentence frames in CDS enhance word recognition in infants.
- This facilitation may stem from enabling infants to 'listen ahead' for expected words.
- CDS structures like sentence frames offer perceptual advantages for early language acquisition.

Higher Mental Functions of the Brain: Language
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...
