  • 1. CognitivePerformance: Whatmoves the needle?Leon WurfelOptimOZ – www.optimoz.com.au
  • 2. Introduction• Cognitive performance and why it is important to me• Tools to measure and optimise cognitive performance• The experiment: • The “lab” • Variables • Method• Outcomes: • Limitations • What else did we learn? • What actually “moved the needle”?• Questions/Discussion
  • 3. Cognitive performance• Cognitive performance = making the most of your brain power = self improvement• How do you do everything at once? • Succeed at your job • Run a business • Learn and develop • Be a good partnerGot to make the most of things• Have gone from meditation – productivity techniques – QS/biohacking techniques
  • 4. Cognitive performance• How do you measure it? • Psychometric tests: IQ, Executive functioning etc • Proxies for the above (i.e. online versions) • QS techniques: dual n-back, free cell, Lumosity• How do you improve it? • Supplements • Nootropics • Healthy lifestyle • Training
  • 5. The experiment – the lab• Online cognitive testing lab: Quantified mind (www.quantified- mind.com)• Can set up your own experiments and collaborate• Has an analytics engine to do all the stats work for you
  • 6. The experiment – the method andvariables• Testing a range of cognitive • Tested for impacts of: functions: • Modafinil • Choice Reaction Time • Piracetam • Color-Word (Inhibition) • BP Coffee • Visual Matching • BP compliant diet • Sorting • General supplements • Finger Tapping • Upgraded aging • Attentional Focus • Mindfulness (that day) • Coding • Mindfulness (day before) • Self-Paced 3-Back • Creatine • Binaural beats • Super supplementing B vits
  • 7. The experiment – the method• Aiming for 50 sessions (@~15 min each)• Started about 3 months ago• So far have completed 15 sessions (life gets in the way)• Going to keep the study going and see where it goes
  • 8. Limitation #1 – Practice effects• A practice effect is where you get better due to better skill at the tests. This confounds the outcome of the experiment• Quantified-Mind stats engine takes care of all that for you• Or you can do your own regressions/residuals blah blah blah - YUK(note that exporting data from quantified mind isn’t very user friendly)

  • 11. Limitation #2 – Sample size• Only 15 data points – is this enough to draw any conclusions from?• Exacerbated testing across so many variables Variable % Modafinil 43% Piracetam 86% BP Coffee 79% BP compliant diet 43% General supplements 79% Upgraded aging 57% Mindfulness (that day) 21% Mindfulness (day before) 7% Creatine 0% Binaural beats 36% B vits 64%
  • 12. Variable %What else did we learn? Modafinil 43%• Tracking your behaviour can tell Piracetam 86% you some surprising things BP Coffee 79% BP compliant diet 43% • Which behaviours are habits? General supplements 79% • What are confounding factors that Upgraded aging 57% affect your behaviour Mindfulness (that day) 21% Mindfulness (day before) 7% Creatine 0% Binaural beats 36% B vits 64%
  • 13. What moved the needle?• Attentional focus?
  • 14. What moved the needle?• Attentional focus?
  • 15. What moved the needle?• Choice reaction time?
  • 16. What moved the needle?• Choice reaction time?
  • 17. What moved the needle?• Coding?
  • 18. What moved the needle?• Coding?• Also a weak association with piracetam
  • 19. What moved the needle?• Colour word inhibition?
  • 20. What moved the needle?• Colour word inhibition?• Also a weak association with piracetam
  • 21. What moved the needle?• Attentional focus?
  • 22. What moved the needle?• Finger tapping?
  • 23. What moved the needle?• Finger tapping?• Modafinil and BP compliant diet were weak associations
  • 24. What moved the needle?• Self paced 3-back?
  • 25. What moved the needle?• Self paced 3-back?• Piracetam has a weak association with increased performance
  • 26. What moved the needle?• Sorting?• Modafinil and bi-naural beats had weak impacts on performance
  • 27. Variable %Conclusion Modafinil 43%• B-vitamin “super Piracetam 86% supplementation” and modafinil BP Coffee 79% had the most significant improvements BP compliant diet 43%• Piracetam, BP compliant diet, bi- General supplements 79% naural beats have weak impacts that could warrant further Upgraded aging 57% investigation Mindfulness (that day) 21%• Experiment will continue in order Mindfulness (day before) 7% to deliver more conclusive results Creatine 0% Binaural beats 36% B vits 64%
