Brief summary
Balance is the ability of an individual to maintain posture against gravity and sustain stability during movement; it depends on the coordinated functioning of the proprioceptive, visual, and vestibular systems, as well as the central nervous system. Current studies show that movement control occurs not only through the motor system but also through the interaction of sensory-cognitive-motor components. Cognitive functions encompass processes such as attention, memory, visuospatial skills, and executive functions, with attention and visuospatial processing playing a particularly important role in balance control. The literature reports significant relationships between balance and cognitive functions, particularly noting that increased attention requirements in dual-tasking situations negatively impact balance performance. Furthermore, it has been shown that both balance performance and cognitive functions are affected by circadian rhythm and chronotype, with individuals exhibiting different performance levels at different times of the day. Despite this, studies examining the relationship between balance and cognitive functions appear to have insufficiently addressed the chronotype factor. Therefore, the aim of this study is to investigate how the relationship between balance and cognitive functions changes according to individuals' chronotypes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Chronotype | baseline - 2 weeks later | It will be assessed by survey (Horne Ostberg). The survey contains a total of 19 questions. Points will be added up based on participants' answers to obtain a score between 16 and 86. 16-30 will be considered evening type, and 70-86 will be considered morning type. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| balance | baseline - 2 weeks later | It will be assessed with KoreBalance balance system. Users will be asked to keep their eyes open while maintaining a center of gravity on an electronic device. Results are presented as point scores. |
| Attention measurement | baseline - 2 weeks later | It will be assessed with stroop test. Individuals will be tested at a desk. They will first be asked to read only the text written in three different colors. Then they will be asked to read the colors of the text. The total score will be recorded in milliseconds. |
| Visuo-spatial attention | baseline - 2 weeks later | It will be assessed with Flanker task. Eriksen Flanker Task is a classic cognitive psychology test that measures selective attention and response inhibition. You are asked to identify the direction of a central target (e.g., an arrow) while ignoring distracting "flanker" arrows on either side, which can either point the same way (congruent) or opposite (incongruent). The total correct responses are kept. |
