Enhancing the formulation of Shared Mental Models in football playersRobbins, Mandy; Newton, Joseph L. (University of ChesterWrexham Glyndwr University, 2020-06-24)A significant amount of research has examined the development of Decision-Making (DM) in sport. However, only a limited amount of research has explored decisions in the context of which they are made. Using the Naturalistic Decision-Making (NDM) paradigm this thesis employs Cognitive Task Analysis (CTA) approaches and Performance Analysis (PA) within a professional football environment, through the lens of a performance analyst. Applying the DM Framework, outlined by Richards, Collins and Mascarenhas (2016), this thesis applied a mixed method approach using three CTA approaches; Critical Decision Method (CDM), Thinking Aloud Problem Solving (TAPS) and Concept Mapping (CM) to examine the development of Shared Mental Models (SMMs). Additionally, PA data was collected to measure on-field application of SMMs in the format of match performance. Method: The development of DM ability was examined using professional footballers (n=16) and professional coaches (n=2), over an eight-week period. PA provided video footage of critical attacking play situations for use in team meetings. Meetings were designed to empower players in the DM process and involved the integration of CTA approaches in the form of a DM booklet. The booklet consisted of questions and diagrams relating to six clips identified by the coaches. Players and coaches would reflect on the clips individually and collectively as a team in an off-field setting. Each clip was split into three Phases, and six clips were shown to all team members in weekly meetings. To ascertain the retention of SMMs developed over the eight weeks, qualitative narratives recorded by the players (DM booklets) were analysed. No CTA processes were applied on week seven, as this was classified as a retention week. The CTA booklet recorded individual team members understanding of the situation and facilitated group discussions after clips. PA analysed data in the form of match statistics to assess transference of SMMs to the field of play. Results: CTA analysed data qualitatively indicated that individual Situational Awareness (SA) improved. Players identified more key themes in weeks six and eight compared to week one, indicating a development in SMMs and increased compatibility of SMM outlined by the two expert coach’s SA. Additionally, the complexity of the players SMMs and team SMMs developed. The PA data illustrated that the team generated more shots on target and more shots on target per Phase 3 entry in weeks six and eight than week zero (pre-investigation). The improved on-field performance of key performance indicators, combined with the increased identification of key themes and growing compatibility of players SMM in line with the expert coaches, demonstrate a more developed SMM which resulted in enhanced DM by the team. In summary, the application of PA and CTA methods within an off-field environment provides a mechanism to develop SMMs in a professional football team which transfer to enhancing on-field team DM in competitive play. However, this work utilising off-field learning environments to enhance DM, is still in its early stages and more research is needed.
