Take-home message: promoting self-regulation capacity + active lifestyles may help students resist unhealthy temptations and maintain balanced nutrition.

But here’s the twist: higher HRV and regular physical activity were linked to less junk food and more fruit/veg intake 🌿✨

Unhealthy foods triggered stronger pleasantness, arousal, and craving compared to healthy options 🍔🍩 > 🥦🐟

🧵5/5 These findings highlight the distinct roles of cardiac interoception and activity in explicit and implicit timing, emphasizing their nuanced contributions to time perception.

🧵4/n Better interoceptive accuracy sped up responses in the implicit foreperiod task. Higher interoceptive confidence led to worse performance in time bisection. Cardiac vagal tone influenced self-paced tapping in explicit timing tasks.

🧵3/n In Study 1, participants (N = 31, M = 23.1 years, SD = 3.23) completed an implicit timing task (foreperiod) and an explicit timing task (time bisection). In Study 2, participants (N = 51, M = 22.6 years, SD = 1.52) performed an explicit timing task (self-paced finger-tapping).

🧵2/n Interoceptive accuracy was assessed using a HCT. Interoceptive sensibility was measured using the Body Perception Questionnaire and subjective confidence ratings (0–9 scale) provided during the HCT. Resting HRV served as an index of cardiac vagal control.

🧵1/n We examined how cardiac and interoceptive signals shape time perception. Implicit and explicit timing were tested via foreperiod, bisection, and tapping tasks.
