The objective was to propose a model that could explain verbal language. This principle ensures efficient storage of information without unnecessary duplication. The principle of cognitive economy asserts that semantic information stored at one level is not redundantly stored at another level, thereby eliminating semantic redundancy within the network. Storage occurs through associations between concepts. The hierarchical organization principle suggests that concepts in memory are arranged hierarchically based on their level of generality, distinguishing between superordinate (more general) and subordinate (more specific) categories. Two fundamental principles emerged from their work: hierarchical organization and cognitive economy. They sought to answer questions such as how we mentally represent and access knowledge in semantic memory and what kind of organizational structure enables human beings to comprehend and employ concepts. Their model focuses on the conceptual organization of knowledge within semantic memory.
The pioneering model that explores the representation of semantic networks was developed by Collins and Quillian in 1969. In this way, we possess a collection of information about the world without an associated context. To grasp the concept of decontextualization, let’s consider the following question: What is the capital of France? If you can swiftly respond with “ Paris,” it demonstrates your knowledge without knowing the specific context in which you acquired it or where it originated. It exhibits the phenomenon of invariance, where, regardless of the existence of various cat breeds, a cat is always recognized as a cat. In semantic memory, information is detached from specific contexts. Our general knowledge of the world is stored in semantic memory, which functions as a network of general knowledge. Another type is semantic memory which we are talking about. It allows us to remember specific details, such as what we did yesterday or the last vacation we took. One type is episodic memory, responsible for recalling personal experiences and events. Within long-term memory, various types of memory exist, each serving different functions. Long-term memory is a vast and intricate storage system that retains information for extended periods.
