Mathée-Scott, Janine; Larson, Caroline; Venker, Courtney; Pomper, Ron; Edwards, Jan; Saffran, Jenny; Ellis Weismer, Susan – Journal of Autism and Developmental Disorders, 2022
To efficiently learn new words, children use constraints such as mutual exclusivity (ME) to narrow the search for potential referents. The current study investigated the use of ME in toddlers with autism spectrum disorder (ASD) and neurotypical (NT) peers matched on nonverbal cognition. Thirty-two toddlers with ASD and 26 NT toddlers participated…

We hypothesise that of the two processes underlying declarative memory, recollection is impaired in high-functioning autism (HFA) whereas recollection and familiarity are impaired in low-functioning autism (LFA). Testing these hypotheses necessitates assessing recollection and familiarity separately. However, this is difficult, because both…
