Why the Single Responsibility Principle Protects Working Memory

Short summary

The Single Responsibility Principle protects working memory by limiting conceptual frames within code boundaries, reducing context switching and cognitive load. When a boundary mixes responsibilities, readers must repeatedly switch mental models and simulate code execution. Applying SRP at the class, method, and package level—supported by naming patterns like purpose, role, and constraint suffixes—enables pattern recognition over simulation, making code more readable.

• •SRP reduces cognitive load by stabilizing conceptual frames within code boundaries
• •Mixing responsibilities forces context switching and mental simulation instead of pattern recognition
• •Good naming patterns (purpose, role, constraint suffixes) enable pattern recognition across classes, methods, and packages
