With a view to finding out how the dental hygienist looks at and recognizes the changes in facial expression and behavior of a mother who is staying by her child just receiving dental care in the treating room, actions which the mother takes near her child were recorded and subjected to observation by a dental-hygienist apprentice. The eye movements of the apprentice were then recorded and analyzed, using the Visicon-Eye-Camera. The results obtained are as follows: 1. In all scenes of the test image, the subject closely observed the mother's face, the child's face and trunk and the dentist's face at a high frequency. 2. In all scenes of the test image, the subject tended to observe closely the mother's face in the former half of his observation and the child's face and the dentist's face in the latter half. 3. In a scene during which the mother looked anxious, the subject tended to look a longer time per observation. 4. In a scene during which there occurred only a change in the mother's expression, the subject frequently took the mother's face, the child's face or the dentist's face as his primary point of observation. 5. The scanning path of the subject was not influenced by a change in the mother's expression, but rather was influenced by the addition of new elements into the scene such as her grasping of the child's hands. 6. In case of the mother beginning to make a body movement, the subject frequently took the mother's face and her child's face as his primary point of observation. 7. The subject tended to make close observation of the dentist's face less frequently with more changes in the mother's behavior, suggesting his tacit cognition of the dentist being there. 8. The above results reveal that the dental hygienist is not visually influenced by the co-existence of a mother and her child just receiving dental care in the treating room if only she is looking at her child in a relaxed manner without any anxious expressions and attitudes.
为了了解口腔保健员如何看待和识别在治疗室陪伴接受牙科护理的孩子的母亲的面部表情和行为变化，记录了母亲在孩子身边的行为，并由一名口腔保健员学徒进行观察。然后，使用Visicon-Eye-Camera记录并分析该学徒的眼球运动。获得的结果如下：1. 在测试图像的所有场景中，受试者都以较高频率密切观察母亲的脸、孩子的脸和躯干以及牙医的脸。2. 在测试图像的所有场景中，受试者在前半段观察中倾向于密切观察母亲的脸，在后半段观察中倾向于观察孩子的脸和牙医的脸。3. 在母亲看起来焦虑的场景中，受试者每次观察的时间往往更长。4. 在母亲表情仅发生变化的场景中，受试者经常将母亲的脸、孩子的脸或牙医的脸作为主要观察点。5. 受试者的扫描路径不受母亲表情变化的影响，而是受场景中添加新元素的影响，例如她握住孩子的手。6. 当母亲开始身体移动时，受试者经常将母亲的脸和她孩子的脸作为主要观察点。7. 随着母亲行为变化增多，受试者倾向于较少频繁密切观察牙医的脸，这表明他对牙医在场的默契认知。8. 上述结果表明，如果母亲以放松的方式看着孩子，没有任何焦虑的表情和态度，那么口腔保健员在治疗室中不会受到正在接受牙科护理的母亲和孩子同时在场的视觉影响。
