Abstract
In this paper we mainly discuss two topics of the face studies. First topic is typical and atypical development of face processing. Recently to investigate the atypical social development, infants' research with high risks is hot topic. In this case under 12 month old babies who have an older sibling diagnosed with the disorder were selected for high-risk infants. Plenty of data has documented impairments in face processing in individuals with autism spectrum disorders(ASD). And recently, suggestion has been made that these impairments may arise from abnormal development of a subcortical system involved in face processing that originates in the magnocellular pathway of the primate visual system. McCleery et al(2007)found that contrast sensitivity of the high-risk infants exhibited greater sensitivities than that of control infants. Second topic is verbal and non-verbal communication studies. In developmental studies we found similarity of the development pattern between language and face processing. Further, we discuss importance of the infant's ability to learn faces in poor resolution. Infant's face learning model(Valentin et al,2003)showed that poor image faces(low-pass faces)made facial learning easy, additionally this low-pass face learning could generalize to the normal faces. In a sense, infant's poor acuity decreases the information in the face processing and this makes face learning easy. high risks is hot topic.
