Face is one of the most common in the outside world as socially critical and important visual stimuli. Facial pareidolia is a condition in which the brain perceives an image that is not actually a face as a face., Functional speech disorder is divided into two subheadings as phonological and articulation disorders according to the American Speech-Language-Hearing Association. Phonological disorder is based on linguistic problems, while articulation disorder is based on motor production problems. It is known that children with functional speech disorders also show lower performance in visual perception than children with normal development and there are differences between the auditory-visual integration areas of the brain between the two groups, that the lip-reading performance of children with functional speech disorder performs differently than children with normal development. We examine the brain activations of face pareidolia perception in both normally developing children and children with functional speech disorders using Electroencephalogram (EEG) recording in our study. Total of 20 children, 10 with functional speech disorders and 10 with normal development, were shown the face, pareidolia, non-pareidolia, non-face cards to the children. They were asked whether they saw faces or similar pictures, and the duration and answers were recorded as a preliminary study. Behavioral outcomes were analyzed. There was a significant difference between children with functional speech disorders and those with normal development. The responses of children with normal development and functional speech disorder to face pictures were close to each other. Children with functional speech disorder had lower rates of recognizing pareidolia pictures as faces. At the same time, the response time of children with functional speech disorder to pictures of faces and pareidolia was longer, and the response time of pareidolia pictures was found to be longer than the response time of faces. Our results are consistent with our preliminary study, as the visual perceptions of children with functional speech disorders are different from those of children with normal development.
