Error detection mode (EDM) allows coaches to objectively assess an athlete's behaviour to incorrect responses. This powerful tool allows coaches to get deeper insights into an athlete's decision-making behaviour and how this can change over time with the correct interventions applied to the cognitive training program. Research has shown that the ability to detect an error in one’s own performance and then to improve ongoing performance based on this error processing is critical for effective behaviour. Researchers also found post-error reaction times indicated two distinct patterns of behaviour, with significantly faster RT, or speeding-up, following an Aware error (pre-error trial RT minus post-error trial RT = 118 ms, t12 = 3.54, P < 0.01) and slowing down after Unaware errors (42 ms, t12 = 2.62, P < 0.05).

How does this help in real-world sports performance?

If you have a team of athletes engaging in a cognitive training program and the data is indicating that some athletes are faster after an error but other athletes dramatically slow down their response speed after an error this could be problematic in high-pressure game situations. EDM mode allows you to test and train error detection and allows you to adapt the cognitive training program to include more audiovisual feedback to manipulate the athlete's behaviour to responses.

If you have applied EDM mode to a task you will be able to see an athlete's Reaction Time (RT) and EDM Reaction time (EDM) on the Soma Analytics tooltip. If an athlete has adopted a strategy to avoid making future mistakes this will reflect in a slower EDM reaction time. Initially, you will see a large gap between the Cognitive Tasks RT and EDM RT but as the athletes, implicit detection abilities improve this gap should reduce and you will find the EDM Reaction time will be faster than the cognitive task's average reaction time.


EDM mode is designed to give athletes live-response feedback. If an athlete makes a mistake, they will want to avoid another mistake, and so to make this happen they might adopt a strategy of slowing down after incorrect responses. By applying EDM mode you are giving athletes real-time feedback to optimize cognitive performance after incorrect responses.
