Ok all you parents whose kiddos play keeper and those who think goalkeeper is the greatest position on the pitch. With pk's overwhelmingly favoring the shooter, can keepers influence them with a simple optical illusion.
This interesting article seems to provide data that says they can.

No rule against it. Goalie jerseys are loud for a similar reason, your eye is drawn to the loud color and your foot follows. Older players can ignore it but as we see kids usually kick the ball right to the Goalie. The question I have is would it be better to make yourself big to influence a shot over the bar or small to try to get the shot close to you?

The study showed opposite what you would rationally think. Based on using the priciples of the Muller-Lyer optical illusion and the shooters perception of the keepers size. The keeper would have a better chance of stopping the pk by making himself/herself appear smaller. I guess the principle might work in reverse, making yourself bigger to push the shot over or wide.

I think it would depend on the age group as younger players usually have a harder time elevating the ball with accuracy. I've read a few other things about the slightly off center thing. Subliminally makes the shooter go towards the open side.

Yes, the article provided a link to another study based on that. The keeper standing off center to influence the direction of the shot. Very interesting concepts nonetheless.

Standing off center worked great for my DD until this year U14
However her old coach did not help things by yelling get to the center as the ball was in the air Rolling Eyes she had a 87% save rate
mainly in D-2...This year she is 1 of 2...her team is good about not fouling in the box
