Title: Observing Implicit Statistical Learning Over Time in Individuals with Aphasia

Abstract: Implicit statistical learning (ISL) describes the process of recognizing and learning regularities in the environment, such as grammar. Numerous studies have used artificial grammar learning (AGL) paradigms to examine this process, but generally, these paradigms do not allow for observation of learning over time of complex grammar. Observing learning over time could have clinical implications as well as implications for how ISL is studied. In children and adults with language impairments, ISL may happen on a slower or less predictable timeline. Therefore, tracking learning as it is happening would be a more efficient way to identify, observe, and potentially shape ISL. We observed ISL over time using a complex artificial grammar in 4 adults with aphasia, 4 age-matched older adults, and 20 younger adults without significant neurological history. Evidence of ISL over time in these groups and individual behavioral responses will be discussed
