Face perception refers to an individual's understanding and interpretation of the face, particularly the human face, especially in relation to the associated information processing in the brain. According to researchers, the face perception in Japanese children almost matured by the age of 13, earlier than in western children.
"This is the first study to investigate the development of face perception in a large number of Japanese children. We are expecting that this result can be applied for understanding of the face perception of the children with the autism spectrum disorder," explained Miki Kensuke from the National Institute for Physiological Sciences in OKazaki, Japan.
The Japanese research team analyzed the face-related N170 component by viewing an upright face, inverted face and eyes stimuli in 82 Japanese children aged between eight and 13-year-old.
N170 was longer in duration and/or had at least two peaks in the 8 to 11-year-old children, different from adults, whereas it was sharp and had one peak in the 12 to 13-year-old children, similar to adults.
The team concluded that the face perception of Japanese children almost matured by the age of 13 years.
In addition, the findings differed from those of previous studies of western children with regard to the age at which the adult response pattern was observed.
It showed that cultural differences might have been one of the reasons for this.
The study was reported in the journal Frontiers in Human Neuroscience.
