3. In this module you will… •  Understand the importance of interpretation in performance analysis. •  Exposure to a theoretical foundation to justify your observations. •  Understand the role of thought process to assist in decision making. 12/2/18 3
4. Question… Can you perform well and still lose? 12/2/18 4
5. Start with semantics •  Science is loosely used as a term in sport to describe the act of scientific investigation that incorporates a scientific method. •  Art is often used as every other means of enquiry, but most commonly ‘gut feel’. 12/2/18 5
6. Start with the perception of science •  Science is commonly seen as an objective and truthful account of the universe. •  Science is also seen as an unbiased method of testing ones assertions. •  Science can provide evolving theories on the nature of things e.g. Newtonian physics à Relativity à Quantum mechanics 12/2/18 6
7. What can science do? •  Science is concerned with what and how questions e.g. how does the heart work? What does the heart do? •  Science provides a platform to challenge existing theories based on observed evidence. •  Scientific evidence provides us with ability to justify claims made based on rigorous analysis. 12/2/18 7
8. Limitations of science •  Science can not give us any answers of why things exist. •  Science does not concern itself with the metaphysical e.g. why is the heart there at all? –  The presumption is that the how and what questions will provide all we need to know about something. •  Scientists do not tend to engage with the philosophies anymore. –  Science was originally call natural philosophy and was inseparable. –  Thomas Kuhn: normal scientist vs revolutionary scientist 12/2/18 Kuhn (1962) The structure of scientific revolutions 8
9. What about the perception of Art? •  Art, at least in the popular culture of the sports setting, refers to decisions/opinions that do not have obvious reproducible evidence. •  The ‘art’ of sport comes from experience, domain specific knowledge, logic and reasoning. 12/2/18 9
10. What can art do? •  Art enables an expression of a certain vision of reality •  Blends what is currently understood with other ideas. •  Can be spontaneous and impulsive or reasoned through discussion. •  Art will sometimes question why things exist and ponder that through expression. 12/2/18 10
11. Limitations to art •  The premise for any discussion must be agreed on for a conclusion to be reached. This is difficult without evidence or a consensus. 12/2/18 11

13. Objectivity v Subjectivity •  This is the most critical distinction between art and science in the sporting debate. •  Objectivity: Being the object of perception or thought; belonging to the object of thought rather than to the thinking subject. •  Subjectivity: Existing in the mind; belonging to the thinking subject rather than to the object of thought 12/2/18 13
14. Things that are Objective 12/2/18 14
15. Things that are subjective 12/2/18 15
16. How does this influence us? •  Meaning is purely subjective. •  Performance itself is objective. •  For us to make an ‘meaningful’ account of performance we must understand the subjective nature of the meaning. 12/2/18 16
17. Money as an example •  The paper that we call money is objective. •  However, the notion of money is subjective. •  The value people place on money is subjective and therefore the models associated with predicting market behaviour are poor because they deal in the objective (Taleb, 2007). 12/2/18 17
18. What about sports performance? •  Sport performance is objective. •  Whether that performance was good or not, above or below expectations or not, acceptable or not is subjective. 12/2/18 18
19. Interpretations influence performance evaluations •  Atomistic •  Hierarchical •  Systemic 12/2/18 19
20. Atomistic model 12/2/18 20
21. Hierarchical model 12/2/18 21 Performance Tactical Performance Decision Making Game Involvement Technical Performance Skill Efficiency Technique Physical Performance Work Rate Movement Efficiency
22. System 12/2/18 22
23. How do we use art and science in sport? 12/2/18 23
24. How do we make decisions then? •  System 1 and System 2 thinking (Kahneman, 2007) – System 1 = intuitive and impulsive decisions with little thinking and energy required. – System 2 = rational, slow well reasoned decisions, requires computation and rational thinking. 12/2/18 24
25. System 2 - Thinking •  Main methods of reasoning – Inductive reasoning – Deductive reasoning – Abductive reasoning 12/2/18 25
26. Reasoning 12/2/18 26
27. Reasoning in a sport context •  Deductive Reasoning: –  Talent can be identified through physical testing –  My physical test correlates with the outputs of the sport –  Therefore, my test can identify talent. •  Inductive Reasoning: –  I’ve had several people identified from my test battery –  Therefore, talent can be identified through the test battery. •  Abductive reasoning: –  I’ve had an athlete won the race –  This can be explained by the test battery results… –  This can be explained by their skill levels… –  The best explanation is ??? 12/2/18 27
28. Using Reasoning •  Each approach has it’s own objectives. •  Deductive reasoning sources to make a conclusion based on the rule and the premise •  Inductive reasoning sources to prove or disprove the theory based on the observation. •  Abductive reasoning sources to determine the most probable explanation for the premise. 12/2/18 28
29. Hopefully you have… •  Understood the importance of interpretation in performance analysis. •  Been exposure to a theoretical foundation to justify your observations and observed the importance of reasoning the evidence appropriately. •  Understand the role of thought process to assist in decision making. 12/2/18 29
