As the quarterback steps back to pass, the offensive line blocks out the defense, so the quarterback has plenty of time to check out what is happening downfield and hits an open receiver. Later in the game, two 300-pound linemen get through to the quarterback. While he scrambles for safety, he fails to see the open receiver downfield and instead throws a pass toward another receiver that is almost intercepted. How can these two situations be related to the way selective attention is affected by task load? LO1
