People with aphasia can have problems understanding or using numbers in everyday life - known as functional numeracy difficulties. However, testing this is hard because there are limited published assessments for functional numeracy difficulties for people with aphasia.
This study aimed to explore, validate and pilot a wide-ranging, aphasia-friendly functional numeracy assessment to investigate how functional numeracy is impacted by aphasia severity and time pressure demands, and to explore predictors of PWA's functional numeracy.
The paper is:
Which blueberries are better value? The development and validation of the functional numeracy assessment for adults with aphasia' https://onlinelibrary.wiley.com/doi/full/10.1111/1460-6984.12867
