Summary
Children with functional articulation disorders most frequently substitute or omit sounds, particularly dental consonants. Errors like lateral and palatalized misarticulations are more common in older children.
Area of Science:
- Pediatric Speech-Language Pathology
- Childhood Communication Disorders
- Phonological Development
Background:
- Functional articulation disorders (FADs) are common in children, impacting speech clarity.
- Understanding specific error patterns is crucial for effective intervention.
Purpose of the Study:
- To investigate the clinical characteristics of FADs in children.
- To differentiate diagnostic features based on age groups.
- To inform speech therapy strategies for FADs.
Main Methods:
- A cohort of 172 children diagnosed with FADs was studied.
- Participants were divided into two age groups: 4-5 years and 6-10 years.
- Phonological samples were collected and analyzed to identify error patterns.
Main Results:
- Substitution and omission (deletion) were the primary error types across both age groups.
- Dental consonants were most frequently misarticulated; bilabial and labio-dental consonants were least affected.
- Older children (6-10 years) exhibited higher rates of lateral and palatalized misarticulations, primarily involving lingual and dental consonants.
Conclusions:
- FADs predominantly involve dental consonants, with bilabial and labio-dental sounds rarely affected.
- Substitution and omission are the most prevalent error patterns in FADs.
- Lateral and palatalized misarticulations are characteristic of lingual and dental consonant errors in FADs.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

01:10Higher Mental Functions of the Brain: Language
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
