NLS Receptive Stimuli: Lexical Stress Assessment Data for Neurotypical Adults and Children

Two novel lexical stress tasks developed to assess prosody without literacy demands, using familiar multisyllabic words. The dataset includes results from 40 neurotypical adults and 15 typically developing children aged 5–11 years who speak mainstream US English. Jill C. Thorson published the data on figshare in 2026 under a CC-BY-4.0 license.

Use Cases

• Training models to identify acoustic cues for lexical stress based on duration and intensity data mentioned in the description
• Benchmarking new prosody assessment tools against the NLS tasks described as psychometrically promising
• Studying developmental patterns of lexical stress perception in children aged 5–11 years
• Comparing task performance between receptive (picture identification) and expressive (picture description) modalities

Strengths

• Data is derived from 55 total participants (40 adults, 15 children), providing a human-subject basis
• Includes both perceptual judgments and acoustic analyses of expressive productions
• Uses familiar words embedded in meaningful contexts, which the description suggests supports ecological validity
• Explicitly designed to reduce metalinguistic and task-related demands compared to existing assessments like the PEPS-C

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data is limited to speakers of mainstream US English, which may limit generalizability
