According to Kolesnik, what is the reorganisation of concept?

Concepts are the categories of objects, events, or ideas with common properties. If you recognize a concept it will help you to generalize and relate to a particular category of events or objects and think logically in that direction.

Thinking: The term "thinking" embraces a wide range of cerebral activities. It subsumes reasoning, judging, conceding, imagining, and problem-solving. 

• Thinking is a complex process involving the manipulation of information.
• Without clear thinking, we cannot communicate clearly.
• Some of the definitions of thinking are

1. Ross: Thinking is a mental activity in its cognitive aspect.
2. Kolesnik: Thinking is the reorganization of concepts.
3. Woodworth: Thinking is the mental exploration for finding out the solution to a problem.

Characteristics of Thinking:​

• Thinking consists of reorganization and restructuring of the material. 
• Thinking gives rise to the discovery of new theories and systems. 
• Thinking is Cognitive activity: Cognitive means something which involves the mental process of acquiring knowledge which thinking surely does.
• When we want to make a decision, we sometimes think about the future such as the future consequences of the decision which is thinking forward and sometimes past to recall my experience and knowledge of a situation which is thinking backward. All these are part of the thinking process.
