Answer:
personality
Explanation:
According to my research on studies conducted by various psychologists, I can say that based on the information provided within the question this is an example of Sondra's behavior being influenced by personality. Personality is individual differences in characteristic patterns of thinking, feeling and behaving. Shyness is part of a person's personality and usually leads to not wanting to be around people including not liking speaking in front of crowds.
