Functioning, temporal resolution, and functional health literacy in children aged nine to twelve years.

The 53 children were a convenience sample, which the authors say prevents generalising the results. Recruitment through social media brought low uptake, and the authors suggest that parents who were already worried about their child's development may have been the ones who responded, which could explain why so many children had abnormal RGDT results. Only 12 of the 53 children attended private school, which the authors say undermines any comparison by school type. Everything was measured at one point in time, so the study cannot show whether communication difficulties come before poor health literacy or follow from it. The conversation category came from parents' or guardians' reports, not from the children themselves; the authors note that caregiver report and child self-report often disagree and may explain why their findings differ from studies in which children described their own difficulties.

The study was paid for by Brazilian public research agencies: FAPEMIG (Universal Demand, process APQ-01354-18), a CNPq research productivity fellowship (308647/2018-1) and CAPES (funding code 001). No commercial sponsor and no competing-interest declaration appear in the text provided.

Do not read this as evidence that poor auditory timing causes poor health literacy, or that training temporal resolution would improve it. The RGDT was not associated with the conversation category, the study measured everyone once, and the sample was 53 children recruited by convenience, half of them through social media. It shows a link between reported communication difficulty and lower health literacy scores, not which came first or why.
