 Presentation Format Affects Comprehension and Risk Assessment: The Case of Prenatal Screening

We studied the effects of presentation formats (frequency, 1-in-N, and visual) and
numeracy level on students’ understanding of prenatal screening results, as well as
their risk assessment for having a fetus with Down syndrome. Frequency format
(vs. 1-in-N and visual formats) improved participants’ ability to accurately assess
the chances of having a fetus with Down syndrome, and was associated with lower
risk estimates. High numeracy levels were associated with a better ability to judge
risk likelihood. For individuals of low numeracy levels, however, the frequency
format significantly facilitated accurate understanding of probability information.
This suggests that presenting information in frequency format is particularly
beneficial for certain populations.
