In a typical development, joint attention, or coordinated attention between social partners to share interest in entities, objects, or events, starts to emerge at around three months of age and gradually grows until about eighteen months of age. Many different species can be seen paying attention together. Despite having a strong ontogenetic and phylogenetic foundation, it is not always apparent, especially in autistic children. In fact, autism spectrum disorder (ASD) is a condition that is early predicted by decreased joint attention in infancy.
