Current Research

Older adults tend to show a relative preference for positive over negative information in memory and attention, a phenomenon known as the ‘Positivity Effect’. My current research aims to further investigate emotion-cognition interactions in ageing and explore how age-related changes in the processing of emotional information can preferentially guide the allocation of cognitive resources towards tasks that are in line with positivity-driven goals. I am particularly interested in the psychobiological aspect of this phenomenon and, more specifically, the extent to which older adults recruit peripheral physiological mechanisms (e.g., cardiovascular system and metabolic resources) to support their positivity preference.

Research Interests
  • Emotion-cognition interactions in ageing
  • Age-related differences in cognitive engagement
  • Metabolic resources (e.g., glucose) and energy expenditure during effortful cognitive processing
  • Psychophysiological indices of effort and affective processing (e.g., HRV and fEMG)
