The listening function is the first modality to develop in utero, forming primary connections with the developing brain. It provides the neurophysiological foundation for communication and learning by integrating and relaying sensory information from within and outside our bodies. The listening function is the active skill that helps children make sense of their inner and outer worlds. When functioning properly, it allows the child to be present and attend to the information they need and leave out the unnecessary or unwelcome “noise”. The listening function helps the child sort and organize this information into meaningful messages. When automatic and effortless, it is an essential component in the child’s spontaneous engagement and motivation.
