One question I have is what age/grade level are we discussing? In any case my best guess is not that the other players are simply ignoring your keeper, but rather that their attention is inextricably locked elsewhere and prevents them from receiving the information. The technical term for the phenomenon is called Inattentional Blindness, and you see it all the time in matches - particularly at the younger ages. The "obvious" pass or shot that isn't made, the "easy" tap in which gets muffed or even ignored completely. In the house it's probably most obvious when you're trying to get the attention of your kid who is engrossed in their video game (or perhaps a book) and the entire place could be burning down or being robbed yet the little bugger wouldn't budge at all despite their name being screamed! LOL Many players have a difficult time simply moving their bodies in space due to deficiencies in strength, coordination, or both...and there isn't even a ball or soccer skill involved. Now factor in shouting from the sidelines (both positive and negative), opponents on the field, perhaps some worry about making a mistake, and don't forget the ball! The pleas of the keeper, who is usually behind all this action looking at the backs of their teammates, adds even MORE to the mix. With all this information flying about those same pleas are easily be overrun by the more "pressing" demands on attention. The solution is to make everyone involved aware of these demands, the chaos it causes with mental processing, and the need to actually slow down a bit. Here is a video which provides a bit of a glimpse into the phenomenon! https://youtu.be/vJG698U2Mvo?si=7PFbjg29RcGBHc8Q
