Article Synopsis
- Positive affect is linked to quicker cardiovascular recovery from stress, but the effects of high-approach (like desire) vs. low-approach (like amusement) positive emotions on physiological responses were not previously explored.
- Two experiments were conducted with 399 participants to assess cardiovascular, respiratory, and electrodermal responses to different types of positive stimuli during stress.
- Results indicated that both high-approach and low-approach positive affects had similar effects on physiological recovery, suggesting that the positive emotional state itself, rather than its motivational intensity, is key for soothing physiological responses.
Article Synopsis
- Heart rate asymmetry (HRA) provides a unique measure of heart rate variability (HRV) by assessing the balance of heart rate decelerations and accelerations, showing additional clinical value beyond traditional HRV metrics.
- Research indicates that psychological factors may impact HRA, yet little is known about how emotions affect it.
- In a study with 30 female participants, findings revealed that positive emotions lead to more decelerations in heart rate compared to negative emotions, indicating that HRA is sensitive to emotional states and can help differentiate between them physiologically.
Dopamine plays an important role in the neuronal regulation of motivation / reward, voluntary movements, cognitive processes and the process of addiction.

Natural antioxidants, besides having a preservative activity, may exert beneficial health effects. Interactions between antioxidants may significantly change their antioxidant activity, thus in designing functional foods or food/cosmetic ingredients knowledge about the type of interactions could be useful.
