Why Does Attentional Blink Happen?

What is Attentional Blink? Attentional blink happens when your focus shifts from one task to another. Since the brain is designed to focus on one target at a time, it becomes difficult to focus on multiple targets at one time. There is a small window where a minuscule gap in attention occurs and attentional blink is created. This happens so quickly that often you don’t even notice. However, if you think back to a time you were forced to focus on many things at once and became frustrated because of the difficulty you may have experienced in your ability to pay attention, you would have experienced attentional blink. The brain’s attention capabilities are limited and it becomes hard to focus on the second target when you are focusing on the first because you are not completely focused on one target item. Splitting attention amongst objects can also cause a person to miss both objects.
Why Does Attentional Blink Happen? There are several different theories why attentional blink can happen. Because our visual environment is in constant change across the dimensions of both time and space, visual stimulation changes rapidly (milliseconds) when viewing any scene, making it difficult for our brain to process everything effectively or to full awareness. In order to process through these limitations our brain is able to filter
This would allow for faster response time. It is believed that with enough training you can retrain the brain and the brain’s signal response to the second target just by providing a better visual for the second target to stand out. This will increase accuracy in the mental processes of the brain’s higher prefrontal cortex, not so much visually, but will give the ability to switch between targets more quickly and allowing for better response
