Preschoolers are sensitive to accent distance

Area of Science:

• Developmental Psychology
• Linguistics
• Speech Perception

Background:

• Children's ability to perceive and process linguistic variations like accents is crucial for social and cognitive development.
• Understanding how children differentiate between native and non-native speech patterns informs theories of language acquisition and social cognition.

Purpose of the Study:

• To investigate whether preschoolers can detect accent differences in speakers.
• To explore how age influences the perception of accent distance in children.
• To determine if children differentiate between foreign and regional accents and the role of prosody.

Main Methods:

• Experiment 1: Four- and five-year-olds judged perceived speaker locations based on accent strength.
• Experiment 2: Children identified alien speakers from utterances filtered for prosody, assessing accent perception.
• Utilized adult ratings for accent strength and controlled for prosodic cues.

Main Results:

• Five-year-olds, but not four-year-olds, placed speakers with stronger accents at more distant locations.
• Children of both ages differentiated alien speakers based on accent, rating foreign accents as more distinct than regional ones.
• Prosodic information was sufficient for children to differentiate accents.

Conclusions:

• Preschoolers, particularly five-year-olds, can perceive accent distance.
• Children may distinguish between foreign and regional accents.
• Prosody plays a significant role in how preschoolers differentiate and perceive accents.
