Description

Supporting materials for the paper "Embodiment and the origin of interval timing: kinematic and electromyographic data." by same authors in Experimental Brain Research DOI:10.1007/s00221-016-4842-y ABSTRACTRecent evidence suggests that interval timing (the judgment of durations lasting from approximately 500 ms. to a few minutes) is closely coupled to the action control system. We used surface electromyography (EMG) and motion capture technology to explore the emergence of this coupling in 4-, 6-, and 8-month-olds.

We engaged infants in an active and socially relevant arm-raising task with 7 cycles and response period. In one condition cycles were slow (every 4 seconds) in another they were fast (every 2 seconds). In the slow condition, we found evidence of time locked sub-threshold EMG activity even in the absence of any observed overt motor responses at all 3 ages.

This study shows that EMGs can be a more sensitive measure of interval timing in early development than overt behavior.INCLUDED FILES Experiment control scripts are included in the zip file: Infant EMG matlab experiment scripts.zip Matlab data analysis files are included in the zip file analysis code.zip Participant summary info - Hands_Summary.xlsx Motion capture timestamps for each cycle start by participant by block Hands.MotionTimeStamps.4sec.csv Hands.MotionTimeStamps.2sec.csv Motion Capture z-axis data by participant by block Hands.MotionData.4sec.csv Hands.MotionData.2sec.csv EMG timestamps for each cycle by participant by block Hands.EMGTimeStamps.4sec.csv Hands.EMGTimeStamps.2sec.csv EMG data (infant bicep) by participant by block Hands.MotionData.4sec.csv Hands.MotionData.2sec.csv Summary peak and trough data by particpant EMG ANOVA by age 2sec.sav EMG ANOVA by age 4sec.sav Peak and trough data by participant by blockemg_anova2s4m.csvemg_anova2s6m.csvetc
