A deep focus in our research Our aims Examine differences between high risk autism (familiar predisposition), perinatal risk and control, studying also factors as cultural issues, socio-economical level...

The Previous work The markers of an atypical development, typical of the autism spectrum, that stand out with greater reliability in early detection are: between six and nine months visual fixations and a strange visual examination, repetitive and unusual exploration of parts of objects, absence of intentional-spontaneous acts of communication, absence of age-appropriate phonemic development, absence of joint-coordinated look, affective and babbling in communicative-social interactions, decreased eye contact and poor social interest and involvement in joint games (Zwaigenbaum et al, 2005)

The main goal is detection and intervention as early as we can We are also interested in find possible red flags about development basis in sleep, feeding, crawling, babble, crying and early markers such as moral development or social perception and orientation The data is being collected at 11 corresponding time points with the following months of age: 2, 3, 4, 5, 6, 9, 12, 15, 18, 24 and 36

Results and further steps

Individuals with major severity in ADOS (cut point>=8 mild<11; ADOS and moderate or severe>=11) and MCHAT (cut point >3) spent significantly less time fixing their eyes in the social stimulus from two video recordings selected by researchers.

Non parametric U Whitman test shows the existence of significant differences in the values of two social videos called AC8 and AC5, this second correlates to a lesser extent with respect to the ASD and non-ASD risk groups.

Results and further steps Analyze the discriminant analysis of the AOI, s selected at earlier ages. Analyze intra subject and inter subject variability within the same risk group.

Assess the predictive capacity of ASD based on tracking patterns and still photos at a given time. Collect more representative samples from each group and jointly evaluate the predictive capacity together with the application of other screening tests
