Declarative knowledge refers to factual information that can be consciously recalled and articulated, including concepts, facts, and definitions stored in memory. It is one of the two main types of knowledge, the other being procedural knowledge, which involves knowing how to perform tasks or skills.

The Concept of Declarative Knowledge

Declarative knowledge is a fundamental concept within the domains of Cognitive Science and Decision Sciences. It refers to the knowledge of facts and information that can be explicitly stated or declared. This type of knowledge is the kind of information that can be articulated or expressed in words, symbols, or other forms of representation.

Types of Declarative Knowledge:

There are two main types of declarative knowledge:

Importance of Declarative Knowledge:

Declarative knowledge plays a crucial role in various cognitive processes, including problem-solving, decision-making, learning, and memory. Understanding declarative knowledge allows individuals to store and retrieve information effectively, make informed decisions, and navigate complex situations.

In Decision Sciences, declarative knowledge serves as the foundation for making rational choices and evaluating alternatives based on factual information. By leveraging declarative knowledge, individuals can assess risks, weigh options, and make decisions that align with their goals and preferences.

Application in Cognitive Science:

Within the field of Cognitive Science, declarative knowledge is studied to uncover how individuals acquire, represent, and utilize information. Researchers explore the mechanisms behind storing declarative knowledge in long-term memory, retrieving information when needed, and integrating new knowledge with existing schemas.

Moreover, understanding declarative knowledge sheds light on cognitive processes such as attention, perception, reasoning, and language comprehension. By examining how individuals encode, store, and manipulate declarative knowledge, researchers can gain insights into the underlying mechanisms of human cognition.


Declarative knowledge serves as the cornerstone of cognitive functioning and decision-making processes. By recognizing the distinctions between structural and procedural knowledge and exploring the applications of declarative knowledge in various domains, we can deepen our understanding of how information influences our thoughts, behaviors, and choices.
