icon arrays suggested potentially promising format communicating risks patientsespecially low numeracy skillsbut experimental studies lacking study investigates whether icon arrays increase accuracy understanding medical risks whether affect perceived seriousness risks helpfulness treatmentstwo experiments conducted samples older adults n 59 62 77 years age university students n 112 26 35 years ageaccuracy understanding risk reduction perceived seriousness risks perceived helpfulness treatmentsicon arrays increased accuracy low highnumeracy people even transparent numerical representations used risks presented via icon arrays perceived less serious presented numerically larger icon arrays 1000 instead 100 icons risks perceived serious risk reduction largericon arrays promising way communicating medical risks wide range patient groups including older adults lower numeracy skills
