A total of 48 photographs of faces expressing the 6 basic emotions (anger, disgust, fear, happiness, sadness and surprise) from 4 Caucasian and 4 Japanese individuals were used as stimuli (Ekman and Friesen, 1976 ; Matsumoto and Ekman, 1988 ). The experiment was conducted using the Presentation (version 14.9, Neurobehavioral System) software on a Windows computer (HPZ200SFF, Hewlett-Packard Company). The images were presented on a 19-in. CRT monitor (HM903D-A, Iiyama) in random order. Written labels of the six basic emotions were presented around each photograph and the positions of the labels were counterbalanced across blocks. Participants were asked to indicate which of the labels best described the emotion expressed in each photograph. They were instructed to consider all alternatives prior to responding. Thus, time limits were not set, and each photograph remained on the screen until a verbal response was made. An experimenter carefully recorded the verbal response. Feedback to their response was not provided for each trial, and the photographs were presented just once. The participants completed a total of 48 trials in approximately 10 min. We confirmed that all participants understood the meanings of the written labels prior to starting the experimental trials. They also performed two training trials to familiarize themselves with the procedure.
