Colm’s research focuses primarily on expert anticipation and decision making. In particular, he is interested in how expert performers utilise the various information sources they have available to them (e.g., opponent action preferences, kinematic/postural cues) to judge opponent intentions. Given the demands athletes are placed under in real-world competition, his research also aims to ascertain how factors such as fatigue and cognitive load affect anticipation. While perceptual-cognitive expertise is Colm’s primary focus, he also conducts research across a range of contemporary skill acquisition topics, e.g., practice structure, instruction, and feedback, to further understand how to design the most effective practice environments for skill acquisition.
