Infant Interval Timing Data with EMG and Motion Capture for 4-, 6-, and 8-Month-Olds

Supporting materials for the paper "Embodiment and the origin of interval timing: kinematic and electromyographic data." include motion capture and surface electromyography data from 4-, 6-, and 8-month-old infants engaged in an arm-raising task with 2-second and 4-second cycles. The dataset contains participant summary information, timestamps, motion data, EMG data, and summary peak/trough data files. Experiment control and data analysis scripts in MATLAB are also provided.

Use Cases

• Analyze sub-threshold EMG activity patterns based on the described time-locked infant data.
• Model the emergence of interval timing coupling based on motion capture z-axis data across different age groups.
• Compare motor response timing between fast (2-second) and slow (4-second) cycle conditions using the provided timestamp files.
• Replicate the study's statistical analysis of peak and trough EMG data by age using the included ANOVA summary files.

Strengths

• Includes data from three distinct infant age groups (4-, 6-, and 8-month-olds).
• Contains synchronized data from two measurement modalities: surface electromyography and motion capture.
• Provides experiment control scripts and data analysis code, which likely supports reproducibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
