and motor activity can be integrated as early as at the beginning of postnatal life and help motivate environment interaction. Consequently, the study of auditory-motor interactions in infancy stands out as highly relevant from both a theoretical and a clinical perspective.

This mini-review aims to summarize and discuss the emergence of auditory-motor interaction and coordination in typically developing newborns and young infants up to 6 months-old, specifically with regard to studies covering behaviors in the upper-extremities in association with auditory stimuli. A specific focus on the upper-extremities was selected as the acquisition of abilities in those limbs during motor development is of great importance for further possibilities for action in, and interaction with, the environment. The purpose is to present some of the research field on early active behaviorvoice according to the side of sound presentation ([@B79]). Mini-speakers were attached to the newborns' right and left wrists and the mother's voice was presented in either speaker. Measuring the distance between the ipsilateral wrist and ear, it was found that the distance between the wrist and ear decreased at the same side as the sound was presented. Recently, another study recorded the amplitude of arm movements to investigate if different auditory conditions (mother's voice, music, and silence) affected the reaching behavior in infants from 10 to 16-weeks-old. The results showed that the amplitude of exploratory arm movements prior to reaching and the number of reaches increased in the mother's voice and music conditions compared with the silence condition ([@B47]). Taken together, these findings suggest that infants older
