I believe the correct answer is: high self-monitoring
Mark Snyder, American social psychologist, introduced the concept of self-monitoring during the 1970s to show how much people monitor their self-presentations, expressive behavior, and nonverbal affective displays. He stated in his studies that self-monitoring can be:
1. high self-monitoring
2. low self-monitoring
High self-monitoring individuals closely monitor themselves and behave in a manner that is highly responsive to social cues and their situational context.
In this case, Sally is high self-monitoring as she examines a situation for cues of how she should react, and then tries to meet the demands of the situation rather than act on her own feelings, before she acts or speaks.
