  1. The left panel shows the best model to explain the mean of the IRI. The right panel shows the best model to explain CV of IRI. In both models, none of the independent variables exhibited significant regression coefficients.
  2. IRI inter-response interval for tapping, IBI inter-beat interval for heart rate, IAF individual alpha frequency.
