Descripción detallada
Introduction:
Autism associates impairments in social relationships and specific competencies linked to restricted interests. These interests usually focus on mathematics, drawings or foreign language learning and are very significant in the autobiographies of persons with autism without intellectual deficiency. It's seem to be a basement of their self-identity. The personal identity relies on both the self representations and the sense of self. This sense of self supports the self continuity through time which links the present feelings, the autobiographical memories and the future personals projects. The personal identity depends on the memory of life events called "autobiographical memory."
Objectives:
The research aims at clarifying the impact of autism on personal identity in adulthood. Two studies will be made in order to compare adults with autistic spectrum disorders without intellectual deficiency and controls. In the first study (Study A), the investigators will ask subjects to tell autobiographical memories and to specify their characteristics by answering focused questions. In the second study (Study B), the investigators will ask subjects to say the self statements which define them. Then, subjects will have to tell and to specify the characteristics of the autobiographical memories linked to these self statements.
Expected Results:
The first study will inform the investigators on the sense of self and self continuity through time. The investigators predict that it would be difficult for subjects with autism spectrum disorders to give details of their life events. The focused questions should make easier the recollection of the memories. The investigators hypothesize that the memories linked to the typically autistic restricted interests would be more detailed.
The second study will inform the investigators on the memories linked to self representations. The investigators predict that these memories would be, in autism, less detailed and less important for identity. The investigators also hypothesize that the memories linked to the restricted interests would be more detailed and important for the self.
Autobiographical memory and socialization are deeply interconnected. So, the investigators think that this research will help them to elaborate news therapies focused on autobiographical memory improvement. Finally, the investigators want to reduce the social disability in autism.

Medidas de resultado primarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
The number of details in the memory (A)/The specificity of the memory (B)
Periodo de tiempo: The number of details or the specificity of the memory is assessed from 1 day to 3 months after the inclusion/baseline
|
study A:The number of details is the total number of perceptual/sensory, temporal, contextual, emotional and cognitive details found in the memory after spontaneous recall first. Secondly, the investigators will ask subjects to clarify the five characteristics of the details presented upper and retrieval should be make easier with specific cueing. Study B:The specificity measures how the memory is focused on specific date, space, context, emotions, thoughts and feelings. The specificity of the memories is deeply linked to the self . |

Study A: the number of remember/ know/ guess responses, the perspective in recollection and the subjective temporal distance in the memory
Periodo de tiempo: This outcome will be assessed on the follow up visit (V2) either one day after the inclusion visit (V1) or within 3 months after V1
|
The number or remember, know, guess responses gives information about the subjective state of conscious awareness during the recall of the memory. This subjective state goes from complete conscious recollection with reliving of thoughts, perceptions, and feelings at the date of the event to a vague impression. The perspective in recollection could be an actor perspective or an observer perspective. In the actor perspective, the recollection is in a first-person point of view. The person remembering relives the event through her own eyes. In the observer perspective, the recollection is in a third-person point of view. The person remembering sees the scene of the memory as the spectator of herself. The subjective temporal distance is the subjective perception of the temporal distance between the present and the event of the memory. The investigators will ask subjects if they feel this event close or distant on a seven point scale. |
This outcome will be assessed on the follow up visit (V2) either one day after the inclusion visit (V1) or within 3 months after V1

Study B:The importance for the self of the memory test1
Periodo de tiempo: This outcome will be assessed on the follow up visit (V2) either one day after the inclusion visit (V1) or within 3 months after V1Description
|
The importance for the self of the memory is assessed by distinctiveness.
The distinctiveness criteria of the memory is established by Conway.
These criteria require participants to specify in what extent these memories have had a personal significance, were discriminatory, consistent and are frequently recalled.
A numerical value will be obtained for this criteria.
