Face Recognition : Effects of Different Encoding Processes and Photographic Mode and Pose

Kim, Yung Che; 金濚埰

Abstract

To examine effects of different encoding strategies and photographic mode and pose on face recognition, two experiments were performed employing the facial episodic memory paradigm. In Experiment 1, experimenter manipulated encoding processes having three levels such as intentional, physical, or semantic one, the photographic pose having two levels such as successive presentation of same two pictures or two of one same and the second new picture, and the test photograph mode either of using the old or new ones. In Experiment 2, the mode of full face photographes used at study and at test was either color pictured or B / W respectively. Furthermore, the pose was either of same expressionless or novel smiling ones. Four conclusions were drawn. First, the semantic encoding processing was not necess~Uily superior to the physical It was more effective when the pose of test photographer was variable, but, surprisingly, the physical encoding was rather better when the pose was constant. Second, when the test photographer were changed either in pose or color, the recognition performance was declined. However, the detimental effect of picture pose was particularly powerful. Third, the color picture was generally positive in effect and, finally, male and females were not different in face recognition ability. Findings were mainly discussed in terms of the model of face processing proposed by Bruce and Young(1986), encoding specificity hypothesis, and amount of information hypothesis.
