This article examines the age-related characteristics of human signaling systems. The cognitive and psychomotor abilities of participants (metaphorization, figurative perception, symbolization, verbalization, abstraction, reflection, and manual skills) are compared, and statistical analysis is conducted. The research results indicate that the key indicators of signaling systems are not significantly dependent on age. However, verbalization and reflection tend to improve with age, while symbolization and abstraction may decline. For statistical analysis, the Mann-Whitney U-test was used. During the study, the methodology "Diagnosis of the Structure of Signal Systems" proposed by E.F. Zeer, A.M. Pavlova, and N.O. Sadovnikova was applied. These findings contribute to a deeper understanding of cognitive processes and their application in educational and psychological practice.
