Chapter 2 introduces you to the AUs of the Upper Face, and as you read the remainder of this chapter, you should look ahead to Chapter 2 to begin applying the logic of FACS. Chapter 2 will take you longer to learn than the chapters that follow it. Beyond learning the descriptions of these AUs, more AUs are described than in later chapters, and you are learning about AUs and the logic of FACS for the first time. Also, until you have read Chapter 3, and learned how to score, and actually have practiced scoring, you will not know exactly how you use the material in Chapter 2. Be patient, some issues will become clearer after you have learned scoring procedures.
It is important that you study the Manual but not that you memorize anything by rote. Your study should be to understand. You will use the Manual as a reference to remind you of the necessary information for scoring. In your initial use of FACS, you will repeatedly look things up in the Manual. Over time you will absorb the material, and will check the Manual less frequently.
The remaining sections in this chapter discuss how the description of each AU in subsequent chapters is organized, with particular reference to Chapter 2. The text explains how the A, B, and C sections are used to understand and score an AU.
