During the study, children's speech and language abilities will be assessed with standardized assessments, and they complete several child-friendly experiments. During these experiments, brain activity will be recorded using specialized caps while children describe pictures, children will speak in two virtual-reality scenarios, and produce speech while keeping to a beat.",[76,77,78],"Stuttering","Stuttering, Childhood","Stuttering, Developmental","2026-04-13",{"date":81,"type":82},"2026-04-16","ACTUAL",{"date":84,"type":82},"2023-06-01",{"date":86,"type":72},"2027-06",{"name":5,"class":6},1]
