Talk about the process of tourists' perception and how these processes affect tourism behavior.

Tourists' perception process refers to tourists' subjective feelings and cognition of the tourism environment in the process of contacting, paying attention to and understanding the tourism environment. These perceptual processes have an impact on tourism behavior, mainly in the following aspects:

First of all, the process of tourists' perception begins with contact. People pay attention to the stimulation within the range of sensory acceptance. This degree of attention is regulated by the difference between stimulating factors and people's expectations. When the stimulating factors are quite different from people's expectations, it is easy to attract people's attention and become the object of perception. For example, when tourists come to a strange city, if the city is different from what tourists expect, it is more likely to attract tourists' attention and perception.

Secondly, selective attention plays an important role in tourists' perception. When facing the complicated tourism environment, tourists will selectively pay attention to and understand some stimulating factors according to their own interests, needs and motives. For example, a tourist who loves history and culture may pay more attention to historical sites, museums and other cultural attractions, but may relatively ignore natural scenery.

In addition, understanding is also an important link in the process of perception. Tourists interpret and explain the perceived tourism environment according to their own knowledge, experience and understanding. This understanding is not only influenced by personal factors, but also by social and cultural background. For example, facing the same mountain, people with different cultural backgrounds may have different understandings and interpretations.

Finally, selective maintenance is the last stage of the perception process. At this stage, tourists will store the perceived tourism environment in their own memory system, and selectively remember and call it when traveling. This selective maintenance is influenced by many factors, such as tourists' interests, needs, motivations and the characteristics of the tourism environment itself.

To sum up, the process of tourists' perception is a complex and changeable process, which is influenced by many factors. Understanding these perceptual processes and their influencing factors will help us better understand the behavior and decision-making process of tourists.
