In a certain type of games, where children are expected to run to a goal point (1) and then to perform something (2), e.g. to run to a bag full of toys and then quickly grab the best toy ahead of the others, my 3.5yo daughter gets the first part "get to the goal point quickly", but after that she stops and does not dare to meddle into a group of kids who are already there and actively snapping up the toys, even though she was one of the first to get to the bag with toys.
After that she waits until everyone is out and then cries because all the "nice" toys are already gone.
Another example is when she was playing a musical chairs (http://en.wikipedia.org/wiki/Musical_chairs) and when the music stopped she was closest to the chair, but when she saw other girl who dashed after it, so she just stood in a stupor and could only do was to ask "where is my chair?".
She does not have the problem "fighting" for her toys, for example in a kindy when someone is trying to seize a toy from her hands, she holds tightly on toy while yelling "it is mine, it is mine". The problem as I described it above is more subtle.
