7 core psychological principles:
- 1. Proximity Principle: Users perceive elements that are close to each other as groups. Place related elements close to each other.
- 2. Von Restorff Effect: What's different is remembered. Use visual differences to emphasize important information.
- 3. Hick's Law: As the number of options increases, decision-making time lengthens. Keep menu items limited and use subcategories.
- 4. Miller's Law: Human short-term memory can process 7±2 items. Divide complex information into small groups.
- 5. Peak-End Rule: People remember the peak moments and the end of experiences. Pay special attention to these points in the user journey.
- 6. Doherty Threshold: Response times faster than 400ms increase user interaction. Optimize your interface's response time.
- 7. Zeigarnik Effect: People better remember unfinished tasks. Use progress bars and incomplete profile notifications.
Consciously applying these principles improves user experience and increases conversion rates.
