<p>In this paper we discuss two topics of infants' studies. First is typical and atypical development of face processing. There are many studies on the atypical social development, especially infants' development with high risks is current topic in developmental disorders. In these studies under 12 month olds who have an older sibling diagnosed with the disorder were selected for high-risk infants. Many studies have documented that impairments of the face processing was found in individuals with autism spectrum disorders (ASD). And recently, abnormal development of a subcortical system originates in the magnocellular pathway of the primate visual system was primary trigger to impairments of higher visual processing. McCleery, Allman, Carver, & Dobkins (2007) reported that contrast sensitivity of the high-risk infants exhibited greater than that of normal infants. Second topic is development of face processing. In these studies we found similarity in the developmental pattern between languages and face processing. Further, we discuss importance for infant's learning faces in poor resolution. Infant's face learning model showed that poor image faces (low-pass faces) made facial learning easily, additionally this low-pass face learning could generalize to process the normal faces. In a sense, infant's poor acuity decreases the information in the face processing during infancy and this promote face learning.</p>
