If you are supposed to respond to either of two kinds of stimuli (such as the letter K or anything green) , then if one comes quickly after another, you are likely to miss the second one. This phenomenon is called?

A) the attentional blink.
B) the Stroop effect.
C) change blindness.
D) the representativeness heuristic.

The phenomenon described is known as the attentional blink, which refers to the difficulty people have in detecting or processing a second target stimulus when it appears soon after a first target stimulus. This has been studied extensively in cognitive psychology and may have implications for multitasking and attentional control. The Stroop effect refers to the interference caused by conflicting stimuli, while change blindness is the failure to notice changes in visual scenes. The representativeness heuristic is a cognitive bias in which people rely on stereotypes or prior knowledge to make judgments or decisions.
