FACS Final Test Instructions
THE ITEMS IN THE FINAL TEST:
The FACS Final Test video consists of 34 videotaped items digitized in MPEG 2 format. Each item on the tape is preceded by several seconds of title that shows the number of the item. The recording of each item is slightly longer than the portion that you actually code. Numbers visible in the picture that change with each video field allow you to locate where to begin and end your scoring. Within each test item, a facial movement occurs. A configuration of AUs appears on the face, reaches maximum contraction (apex) and in most instances relaxes with the face returning to a neutral state. It is this movement that you are to score. Do not score an Action Unit, Action Descriptor or head/eye position that is already evident on the “start frame” unless the contraction (intensity) of that action increases. A list of apex locations for each configuration to be scored appears at the end of this document. This list also tells you the items for which head and eye position must be scored. Be sure to use this list when scoring. Always score the 5 levels of intensity on all AUs. Subjects speak during periods where actions occur on this test. Follow the guidelines in the Manual, Chapter
11, when the person is speaking exactly during the time the action occurs within the test item, briefly summarized next. Code AU 50 to score the speech action of the lips/jaw, and do not score AUs 25, 26 or 27 during speech. If AUs 10, 14, 16, 17, 18, 20, 22, 23 and/or 24, occur during speech, score the AU if it remains on the face for more than one syllable or its apex includes a speech pause. This is a reasonable clue that the AU was not required for the enunciation of speech. The test tape has a sound track so that speech and pauses can be determined.
SPECIAL SCORING RULES FOR THE TEST:
Head and Eye Positions. In scoring Head and Eye positions, assume that subjects are in their neutral position when they are facing towards the person they are talking to or facing towards the camera. [Sometimes this will be a head-on shot, sometimes this will be a shot taken at an angle]. On items that require you to score Head and Eye positions [note that the instructions below tell you on which items you do and do not score Head and Eye position], you are to score deviations from the neutral position. Score only those Head and Eye movements that occur coincident [within a few frames] of the apex of other AU’s which change. Do not score head movements that rapidly change throughout the test item. Do not score Head or Eye positions if a single position that is a deviation from neutral is held through the test item. Blinks. To save time, blinks are not to be scored for this test. (Blinks are obvious and in these items the blink is rarely an essential part of the action or configuration that is being scored.)
In scoring, it will be necessary to use slowed and stop motion viewing to identify the AUs that occur in an item. However, we recommend that each item first be viewed in real-time to make an initial scoring, and that real-time viewing be used repeatedly for verification to check your scoring. AUs that are very brief or that occur only at the A or B level may be almost impossible to see in slowed motion until after they have been identified and roughly located in real-time viewing. In scoring we recommend that you do not spend more than 20 minutes on an item. If you have not made up your mind by then, go on to the next item and return to the difficult item later, preferably in another scoring session. Many items should take you less than ten minutes. Try to set a block of time for scoring on a frequent schedule. Do not attempt to score all items in one or two sittings. After you have finished scoring all 34 items, you should do an additional review step. With your scores in front of you, go through the 34 items once more. Be alert for things you missed. We have found you can review about ten items in an hour.
