The SEAL instrument was applied in 80 double mother-babies, with infants up to 12 months and 29 days, 38 of the case group (infants of children with ASD) and 42 of the control group (infants siblings of children without ASD). The database is secondary, being taken from the research "Vulnerability of parents and siblings of children with autism spectrum disorder", with coordination of Prof. Dr. Rogério Lerner of the Institute of Psychology of USP. As secondary objectives, this study aimed to investigate whether children who were flagged with developmental difficulty by the IRDI instrument (Indicators of Risk for Child Development) and signaled with withdrawal by the ADBB (Alarm Distress Baby Scale) instrument were also those indicated with language difficulty by SEAL. Given a low correlation found, a vignette of the filmed material of a mother-infant indicated only by SEAL was discussed qualitatively. The theoretical discussion is based on authors based on the enunciative perspective, on which the SEAL is based, in addition to the theory of emotional development of the psychoanalyst Donald Winnicott. It was found in the results that infants of the first sub-age group (2 months to 6 months and 29 days) of the group had more language difficulties than those in the control group and that infants of the second sub-age group (7 months to 12 months and 29 days) of the group if they have less language difficulties, when compared to the control group, contrary to expectations. In addition, infants of the...
