Logically, and by the analogy of a language processing study, elder infants were studied in current research to confirm hypothesis about face processing narrowing in 9-month-old infants comparing to 6-month-old infants. Scientists also proposed that adults are much more anthropic orientated and have narrowed their face processing. Pascalis, Haan and Nelson hypnotized that only the youngest group of people (month-old infants) would demonstrate equal face recognition within native specie as well as within strange specie, while 6-month-old infants and adult humans supposed to demonstrate clear and better determination only within native specie.For the experimental proof three studied groups of people were properly formed. They were 11 adults with no specific recognition experience, 30 healthy 6-month-old infants and 30 healthy 9-month-old infants (both group consisted of full-termed babies). Pascalis, Haan and Nelson used the VPC (visual paired-comparison) method for the main experimental method. VPC procedure is a method that was specially developed to study early perceptional function, but nowadays it’s also widely used in other different memory studies. It was firstly developed by Franz in 1956 exactly while studying infants’ perception with stimuli – making changes in infants’ environment and observing responses (Winn 2001). Franz had discovered that infants about 2-3-month-old and elder were spending more time looking at novel stimuli comparing with the time they had spent on processing familiar stimuli (Nelson 2008). In current experiment two stimuli confrontation was used. They were colored images of Caucasian male and female faces and monkey (Macaca fascicularis) faces. During a single time phase familiar and novel pictures of individuals both from the same specie were shown to the studied. Time was the main variable in current experiment. Therefore more time studied spent on pictures face processing within monkey specie comparing to the time spent on processing humans’ faces, more narrowed face perception studied may have.Results have confirmed the hypotheses. For group of adults the time they have spent on novel humans faces processing (novel stimuli were pictures of faces they have never seen before) and the time they have spent face processing the pictures with humans’ faces they have previously seen for several times (familiar stimuli) differed pretty much. Pictures with novel human faces needed more time
