| Outline of Research at the Start |
How do infants handle the massive cues achievable from the natural environment to produce a response even without based on the understanding of meaning? This project proposes to use multi-scale analysis to reveal the complexity of infant-caregiver’s social coordination in natural daily life.

| Outline of Annual Research Achievements |
This project aims to quantify the multi-modality cues on multi-scales in the natural interaction of the infants. A multi-time scale analysis was proposed to reveal the vocal coordination patterns between infants and caregivers. The results show that they are differently coordinated on each timescale with cultural differences. Then, the alignment analysis was extended to the vocal-emotional level, revealing that infants and their caregivers also align on the a higher level. This project also investigated the cardiac activities during natural interaction, revealing the internal interactive progress between the two interactive parties. These findings stress that 1) Infants received varied cues on multi-time scales. 2) The alignment happened on multi-levels 3) and across multi-modality.
