Key result
High trait anxiety is linked to altered attentional processing, change blindness, and HRV.
Why the study?
Few studies have investigated the change blindness phenomenon linked to attentional responses toward salient stimuli while considering the autonomic nervous system's role.
Does heart rate variability and trait anxiety level affect attentional processes toward emotional stimuli in healthy university students?

May link HRV to anxiety-related attention; hypothesis-generating and requires prospective validation before clinical use.

Does heart rate variability and trait anxiety level affect attentional processes toward emotional stimuli in healthy university students?
Heart rate variability is associated with trait anxiety levels and may serve as a predictor of altered attentional mechanisms in anxiety.
Forte et al. (2021) conducted a cross-sectional in Trait anxiety (n=75). High trait anxiety vs. Low trait anxiety was evaluated on Attentional pattern in a change detection flicker task and association with HRV. High trait anxiety was associated with altered attentional processing of emotional stimuli, and an association between heart rate variability, trait anxiety, and change blindness was confirmed.
