On this episode with Dr Calder we discuss:

  • How Dr Calder approached formalising her experiential practise into a research project. 
  • How does she approach or package her offering to teams. 
  • Assessing or breaking down visual performance 
    • Visual Recognition – The ability to see something early and have time to execute 
    • The ability to Judge – Spatial awareness awareness of environment 
    • Visual Awareness – The ability to feel what is around you, peripheral awareness and how quickly we can respond to stimulus around us. 
    • Plus more (reaction time, choice reaction time and more) 
  • Examples of how she trains visual performance following an assessment. 
  • History leaves clues, our abilities and deficits can be related to our sport or activity upbringing. 
  • The benefits of not specialising in sports during youth from a visual performance standpoint. 
  • The online EyeGym program and KPI’s for appraising visual interventions
