Quizplus · Accepted Answer

Current research suggests that stuttering is likely caused by a combination of genetic and environmental factors, and there is no evidence to support the belief that it is caused by unresolved emotional problems, anxiety, or maternal communicative behavior. Some studies have also suggested that abnormal development in certain areas of the brain, like the left hemisphere and basal ganglia, may be linked to stuttering.
