Final answer:
The dominant response in social facilitation suggests that simple or well-learned tasks are performed better in the presence of others due to increased arousal which enhances performance. The answer is (C) - arousal enhances the execution of behaviors one "knows" well.
Step-by-step explanation:
The behavior will be enhanced by the arousal:
The dominant response in the concept of social facilitation refers to the tendency for people to perform simple or well-learned tasks better when in the presence of others. This is because the presence of others typically increases physiological arousal. When the task is simple or well-learned (something the individual is good at), this arousal enhances performance, leading to a display of the dominant response. Alternatively, if the task is complex or not well-learned, the same arousal can impair performance.
Therefore, the correct answer to the question is: C) the level to which you "know" the behavior will be enhanced by the arousal. Understanding the dominant response is crucial in predicting whether social presence will improve or worsen someone's performance. People with high self-efficacy in a particular task who perform it in front of others may experience positive social facilitation, while those less confident or skilled may be hindered.
