Answer:
The answer is mood linkage.
Step-by-step explanation:
Mood linkage occurs when a person "absorbs" the mood in their current environment. For example, when attending a meeting with friends, it's likely that people will feel amused simply because the environment is fun. This can happen the other way around, too: negative environments might result in a bad mood.
The concept of mood linkage has been studied in relation to the workplace: a comfortable work environment results in more productive workers.
