At one end, learners are typically directed to fewer affordances in specified areas of the learning landscape by instructors (symbolised by the uniform shapes, few in number). In contrast, a more diverse and extensive range of affordances is on offer at the less structured end of the landscape for practice designs (symbolised by the rich and varied shapes and sizes available). A form of life is a complex multi-layered system that has a relational nature in regards to how individuals develop a functional relationship with an ecological niche to utilise relevant affordances. The complexity of the process of coaches’ talent selection in sports The four cases of talent selection which can occur. The columns represent the selection or non-selection of an athlete as a talent. Rows represent the actual successful or unsuccessful performance or pick as a talent of the athlete. Average session specificity across the learning intervention. Average specificity refers to the representativeness of the task, with a score of 100 representing a task that matches the competition demands. This is an example of how constraints can be overloaded in elite sport to ensure practice becomes progressively more challenging and more representative of competition. Average information specificity per session. Average specificity refers to the representativeness of the task based on three constraints that influence decision making: the presence of team mates, opponents, and/or a scoreboard. 9 10 27 37 39 51 60 72 73 xii 5.3 6.1 6.2 6.3 7.1 7.2 8.1 8.2 11.1 11.2 11.3 12.1 12.2 13.1 13.2 13.3 13.4 13.5 List of illustrations Cricket Australia’s guidelines for pitch length in junior cricket (grey bars) and children’s average height (black line) from age 7 to 18 as relative to the adult size. For instance, the average 7-year-old’s height is 1.22cm, which is 72 per cent of the average adult height (1.69cm). Likewise, a 14.0m pitch is 70 per cent of the full-sized pitch (20.1m). The text in the grey bars represents the recommended pitch length for each age. This is an example of how constraints can be progressively overloaded in junior sport to match children’s physical capabilities.

As a lay observer, fan, sci­ entist or sporting practitioner (e.g., coach; talent development program coordi­ nator) understanding sporting excellence is a common topic of conversation and investigation. In sport science, understanding the nuances of sporting excellence is an ever-present focus, albeit the particular disciplinary lens under which investi­ gation is conducted (i.e., physiology, motor control and skill acquisition, bio­ mechanics, psychology, coaching, etc.) may vary. Irrespective of disciplinary stance, consistent, core questions are raised, such as: � � � � ‘What constitutes and underpins exceptionality in a given sporting context generically (e.g., soccer; athletics), or in a particular performance task speci­ fically (e.g., long jump in athletics)?’ ‘Can athletic potential be identified?’ ‘How can coaches and athletes optimise their training and preparation to attain exceptionality?’ ‘How can sport-systems be designed to optimise athlete development?’ It is these questions (and others) that have stimulated growing research and applied interest in the inter-disciplinary area of Talent Identification and Devel­ opment (TID) in sport. Mutuality in Research and Practice Expansion – or Is One Pulling the Other? Whilst the origins of athletic talent identification can be traced to the formalised training schools in Ancient Greece (Ghristopoulos, 2003), TID in sport as a multidisciplinary research field (Piggott, Müller, Chivers, Papaluca, & Hoyne, 2018) has expanded considerably in the last two decades, particularly since pub­ lication of the first edition of this text in 2012. A literature search of key research databases using keyword search terms (e.g., ‘talent’, ‘sport’, ‘expertise’, ‘talent development’) as themes, and associated synonyms, identifies more than 2,700 articles published between 1990 and 2019, with an estimated 75 per cent 2 Stephen Cobley, Joseph Baker, and Jörg Schorer published in the last ten years. Expansion is also reflected by the growth of sys­ tematic and narrative reviews of the field generally (e.g., Mann, Dehghansai, & Baker, 2017; Johnston, Wattie, Schorer, & Baker, 2018) alongside sport-specific reviews (e.g., soccer – Bergkamp, Niessen, den Hartigh, Frenchen, & Meijer, 2019; Sarmento, Anguera, Pereria, & Araújo, 2018; Unnithan, White, Geogiou, Iga, & Drust, 2012). In tandem, and over the last decade, many books have been published in both sport and other domains (e.g., The Complexity of Greatness – Kaufman, 2013). Moreover, sport-related texts have been directed toward differ­ ing audiences, including researchers (e.g., Routledge Handbook of Talent Identification and Development in Sport – Baker, Cobley, Schorer, & Wattie, 2017), sporting prac­ titioners (e.g., Talent Development: A Practitioners Guide – Collins & MacNamara, 2017; Developing Sport Expertise – Farrow, Baker, & MacMahon, 2013), and the broader public (e.g., Bounce – Syed, 2010; The Sports Gene – Epstein, 2014). The research interest in sporting TID has arguably grown in concert with, or response to, changes in national government policy and economics, as well as the commercialisation and globalisation of sport (Nagel, Schlesinger, Bayle, & Giau­ que, 2015). As part of what has been termed a ‘global sporting arms race’ (Oakley & Green, 2001; De Bosscher, Bingham, Shibli, van Bottenburg, & De Knop, 2008), national governments (e.g., UK [Green & Houlihan, 2005]) have substantially increased financial investment in national institutions (e.g., the respective English and Australian Institutes of Sport, Canada’s Own the Podium), whose remit has been to systematically attain elite sporting success. For govern­ ments, achieving sporting success at international events such as an Olympics or other highly culturally valued event (e.g., FIFA World Cup) has seemingly pro­ vided political, social, and economic benefit. Partly driven by economic events (e.g., global financial crisis) and neo-liberal economic policy, over similar timeperiods nations’ state-sponsored ‘grass-roots’ sport provision has not shown equivalent growth. Instead, the financial reach and administrative control by sport governing bodies has increased, along with a growing number of indepen­ dent, privatised, sport providers. (Evans & Davies, 2015). As a result, TID pro­ gramming now contains a mixture of centralised state-funded, sport governing body, and local private sector providers. Commercially speaking, an increase in several inter-dependent ‘top-down’ and ‘bottom-up’ demands (Gerrard, 2004) are likely responsible for increased TID programming. ‘Top-down’ demands include corporate organisations (e.g., TV corporations) seeking to attract consumers (audiences) to their sporting coverage. Similarly, sporting consortiums and professional teams within elite national lea­ gues also exert top-down demands, as they seek to attract and/or develop the best senior athletes for (inter-)national success (e.g., the National Rugby League – Australian rugby league; the European Champions League – soccer). The impact of top-down commercial growth is exemplified by increasing global audiences in contexts such as the English Premier League (EPL – soccer) with an estimated 1.35 billion viewers in 2018/2019 (Premier League, 2019). In addition, new international sporting competitions have emerged, such as Indian Premier League (IPL) cricket and the International Swimming League (ISL), both of which attract
