Design Psychology: Principles for Effective Visuals

Cognitive Load  

- Definition: Cognitive load is the measure of the mental effort required to process information.  

- Application in Design:  

  - A user-centred design reduces cognitive load.  

  - This leads to a user‑friendly experience and increased engagement.  

- Key Insight: The simpler and clearer the design, the easier it is for users to interact with it.  

Rule of Thirds  

- Definition: The rule of thirds divides an image into a grid of nine equal parts using two equally spaced horizontal and vertical lines.  

- Application in Design:  

  - Helps create balanced and engaging visuals.  

  - Guides the viewer’s eyes naturally across the design.  

  - Adds depth and harmony to compositions.  

- Key Insight: Placing key elements along the grid lines or intersections enhances visual appeal.
