What forms of a person’s ideas about the objects of the surrounding world?

Ideas about the features of an object or phenomenon are formed on the basis of a combination of sensations (smell, taste, color, surface texture) arising from irritation of the receptors of the sense organs and the perception of a holistic image that appears in the cerebral cortex, and then are recorded in the memory of a person.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
