This article introduces the concept of attention span and illustrates its main characteristics
- diffused attention;
- selective attention;
Diffused (or distributed) attention allows a person to receive more stimuli at the same time. For example, a player enters the field and looks around at everything they can see: goals, opponents, teammates, the grass, the public...
Selective attention allows to filter some stimuli, leaving the irrelevant ones behind: a player who doesn't hear supporters but stays focused on the action.
Focus is when attention is concentrated on a single event or specific inpute and rules out everything else: for example, a player that has to perform a penalty kick.
