The study investigates experiences with autism spectrum disorder (ASD), in interviews with an autistic young man, his mother, father and sister, together with the researcher-speech therapist. There is a literature review on the conventional medical paradigm and neurodiversity, in addition to autism in the family context. The theoretical and analytical positioning involves two main axes, the order of interaction, with the concepts of co-construction, otherness and stigmatization; the order of the narrative, with a Labovian canonical narrative approach, small narratives and positioning. The methodological approach is qualitative and interpretive, with research interviews. The analytical results indicate the realization of narratives by the interviewees, using, in the great majority, non-canonical narratives. Level 1, 2 and 3 placement stands out as relevant with each participant. From the autistic point of view, there are intelligibility about normality and abnormality with emergence of stigma and indication of the need for social inclusion of autistic/neurodivergent people. As for family members, there are differences. The mother shows herself as a caregiver of the autistic son, after retirement. The father reveals himself to be knowledgeable about the autistic son s diagnosis process, to whom he always makes positive attributions. The sister reveals herself to be active in professional experiences with the rights of autistic people. The research seeks to contribute to and for studies on the family s perceptions and constructions about ASD, neurodiversity, social inclusion. It emphasizes the importance of talk-in- interaction in research interviews as a way to encourage reflection, action and change.
