Question

lars is an excellent violinist. in front of an audience, he tends to play his violin even more beautifully than when he is alone. this is most likely due to:
○ social facilitation.
○ deindividuation.
○ the bystander effect.
○ normative social influence.

Explanation:

Social facilitation is the tendency for people to perform better on simple or well - learned tasks when in the presence of others. Lars is an excellent violinist (a well - learned task), and his performance is better in front of an audience. Deindividuation is a loss of self - awareness in groups. The bystander effect is the phenomenon where people are less likely to help in an emergency when others are present. Normative social influence is conforming to gain social approval.

Answer:

social facilitation.
