To think is to form concepts that organize experiences, to solve problems, and to make efficient decisions and judgements. Concept A mental category that groups objects, relations, activities, abstraction or qualities having common properties. Concepts are formed through direct contact with objects and situations, but also by contact with symbols, which represent or stand for something else.
Concepts are the building blocks of thought.
Concepts are formed by definition. Prototypes are the most representative example of a concept. Insight is the sudden flashes of inspiration. Obstacles to Problem Solving Confirmation bias - paying attention to information that confirms what we believe while ignoring information that opposes our beliefs.
