Intra-individual coefficient of variation of response time

1. Intra-individual coefficient of variation of response time mediates cognitive function in humans.

   “Mediation analyses indicated that ICV and preparatory ERP measures partially mediated the relationship between age and cognitive performance.”

1. Intra-individual coefficient of variation of response time is associated with cognitive function in humans.

   “Across the entire sample, higher ICV was associated with lower MoCA scores”

1. Mild cognitive impairment is associated with intra-individual coefficient of variation of response time in humans.

   “individuals in the MCI range exhibited significantly greater behavioral variability (higher ICV) and reduced preparatory neural activity (attenuated BP and pN amplitudes)”
