Summary
The Russian Matrix Sentence test (RUMatrix) is validated for children aged 10 and older. A simplified version (Simplified RUMatrix) is now available with normative data for all ages.
Area of Science:
- Audiology
- Speech-Language Pathology
- Psychoacoustics
Background:
- The Russian Matrix Sentence test (RUMatrix) is established for assessing adult speech intelligibility.
- Its applicability and a simplified version for pediatric use require investigation.
Purpose of the Study:
- To validate the RUMatrix test for pediatric speech intelligibility measurements.
- To evaluate a new Simplified RUMatrix test for both children and adults.
Main Methods:
- The study involved 20 normal-hearing adults and 81 children (5-10 years).
- Both RUMatrix and Simplified RUMatrix tests, featuring unpredictable sentences in noise, were administered.
- The Simplified RUMatrix uses shorter phrases (3 words) compared to RUMatrix (5 words).
Main Results:
- The RUMatrix test showed limitations for children under 10.
- Simplified RUMatrix test list homogeneity was confirmed in adults.
- Children's scores improved with age, reaching adult levels by 10 years.
- A training track is recommended for the Simplified RUMatrix.
Conclusions:
- The RUMatrix test is suitable for children aged 10 and above.
- Normative data for the Simplified RUMatrix have been established for adults and children across various ages.

A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
