Characteristics of Anxiety and Color Perception in Students with Different Chronotypes

Chronotype influences students' adaptation to the educational process and is an individual characteristic. However, the relationship between chronotype, anxiety level and color perception remains insufficiently studied. To identify the features of anxiety and color perception in students with different chronotypes. 42 students (aged 18–24 years) were examined. The Horn-Ostberg test, the Spielberger-Khanin test, and the eight-color Luscher test were used. Statistical analysis was performed using the Pearson chi-square test. The distribution of chronotypes in the sample was: morning type – 6/42 (14.3%), intermediate type – 17/42 (40.5%), evening type – 19/42 (45.2%). No statistically significant relationship was found between chronotype and anxiety level (χ² = 7.83, p = 0.45), nor between chronotype and the choice of the first color in the Luscher test (χ² = 13.5, p = 0.33). Qualitative analysis revealed trends: the evening type more often showed a high level of anxiety (37%) and a choice of blue color (peace); the morning type showed a choice of red (activity) and yellow (optimism). In this sample, anxiety level and color perception do not statistically significantly depend on chronotype. The identified trends require verification in an expanded sample.
