Abstract The acquisition and development of theory of mind (ToM) is an important issue receiving attention of research on infants and toddlers (0－3 years old), involving the research on the processing mechanism of ToM and the establishment of theoretical framework during this period. From the perspective of cognitive neuroscience, we summarize the brain imaging evidence based on the observation of different neuroimaging technologies, for the two components of ToM in infancy and toddlerhood. The results support the view that “children acquire ToM during the age of 0－3”， enriching the lifespan development perspective of ToM and providing comprehensive evidence for exploring the acquisition time, neural processing mechanism as well as the brain network foundation of ToM. In order to prove that ToM has been acquired in the early age, future research can combine cognitive neuroscience and developmental psychology and use a variety of neuroimaging techniques to track the development of children's ToM.
