A high-stress situation in which one finds oneself in another culture in which former behavior patterns are ineffective and one fails to understand the basic cues of social intercourse is termed as culture shock.

In a new culture where there is nothing familiar, the brain finds it difficult to relate the practices, activities, etc. to the experiences from the past and the available knowledge and thus exhibits unresponsiveness.
