Design patterns act as cognitive shortcuts, aligning with [[Chunking theory]] to simplify complex design decisions into manageable, recallable, and reusable units. This approach helps developers efficiently learn, communicate, and apply sound design principles in software development. The [[Chunking theory]] suggests that our working memory can simultaneously hold about seven chunks of information ([[References#^43678f|Colvin, 2019]]). Design patterns like [[Observer pattern]] and [[Factory]] allow developers to encapsulate complex concepts into chunks, making it unnecessary to remember each small component individually. Chunking also helps retrieve information from long-term memory. Developers who understand design patterns can more easily recall specific solutions when faced with common problems. For example, recognizing a need for a [[Singleton]] pattern allows them to retrieve its structure directly, reducing the need to consider multiple alternatives. By enabling developers to work at higher levels of abstraction, design patterns help manage complexity and avoid getting lost in details ([[References#^085997|Freeman & Pryce, 2009]]). Design patterns also create a shared language, enhancing communication in line with the chunking principle. Instead of detailing every solution aspect, developers can refer to a design pattern, allowing team members to grasp the idea quickly and work collaboratively. For beginners, design patterns provide a structured, organized approach to problem-solving, making it easier to understand complex systems. Rather than facing a daunting array of techniques, they can learn modularly, mastering individual patterns as manageable chunks and gradually building a holistic understanding of software design.
