Topic: Long-term memories in Autism Spectrum Disorders: What their pattern of impaired versus spared functions tells us about Semantic Memory?
Abstract: Over the years, there has been significant progresses in theories of semantic memory. Although widely explored, there are still open questions about the structural and functional aspects of this neurocognitive function. Specifically, the interaction of this type of memory with other cognitive functions requires further examination. Recently, the hypothesis that the formation of semantic memory is contextual-based and therefore comes from the episodic memories has been discussed. Consequently, the idea that semantic memory can interact with episodic memory finds plausibly. Studies with Autism Spectrum Disorders (ASD) have indicated a differentiated pattern in the two types of declarative memories, which turns out to be an interesting model for the study of Declarative Memories. In particular, episodic memories are indicated as impaired while semantic memories are generally spared, although there is evidence of some decline in semantic organization. In this presentation, I will briefly present the profile of declarative memories in ASDs. Next, I will focus on the literature about semantic organization in ASD. The hypothesis of the interdependence between semantic memory and episodic memory will laso be considered. Finally, some relevant questions and ideas for future studies will be presented.
