Auditory time perception impairment in children with developmental dyscalculia.
Elisa Castaldi, Francesca Tinelli, Gasperini Filippo and 2 others
PMID 38663331WHAT IT FOUND
Children with developmental dyscalculia were less precise when judging how long sounds lasted.
They heard short and longer sounds as less distinct than age-matched peers, but their average time estimates were not shifted.
Key findings
01Children with DD had higher auditory time sensory thresholds than controls in both short and longer sound ranges, indicating lower precision.
02The precision difference remained after accounting for age, non-verbal reasoning and gender.
03Time perception accuracy was similar between groups in both ranges.

What it does not show
The sample was small, and the authors noted that finding carefully screened children with DD for research is difficult. Two participants did not complete both sessions, so the short and longer ranges were not tested in the same way for all children. The age range spanned several years, so developmental differences within the group may matter. Reading scores were not available for all participants, and the DD group included children with reading difficulties, so comorbid reading problems may not be fully separated.

The easy way to misread this
Do not conclude that auditory timing problems cause dyscalculia or that training timing will help math. The study compared groups and did not test causation or intervention.
