Implication
Cardiac reactivity tracks negative affect in distressed 24-month-olds with sex differences; hypothesis-generating for autonomic-emotion links, needs prospective validation.
Structured PICO

24-month-old infants

Intervention
Four increasingly challenging, emotion-eliciting tasks
O
Outcome
Changes in heart rate, respiratory sinus arrhythmia, and preejection period and their association with negative affectsurrogate
In 24-month-olds, cardiac reactivity (heart rate and respiratory sinus arrhythmia) is systematically associated with changes in negative affect during challenging tasks, with sex differences in these associations.
