The Importance Of Change Blindness

Our attention is very selective when it comes to getting information from our environment. We could be looking at everything within our environment and miss changes that occur while looking. According to Rensink, O’Regan and Clark (1997), attention is a key factor, meaning when our attention is focused on the area of change then change can be detected. When we fail to detect change, it can result in change blindness. In support of this idea, Simons and Levin (1998) suggest that change blindness occurs if there is a lack of “precise” visual representation of their surroundings. In other words, a person can be looking at an object and not fully notice a change. As a result, our attention selection is limited if not directed. Therefore, redirecting …show more content…

Therefore, the informed group would detect more changes than the uninformed group. This was as a result of their attention being pre-directed to the area of possible change. Our attention is based on a selection. In contrast to not having a focused attention, we can easily miss changes within our environment. Therefore, our hypothesis was supported the informed group was better able to detect changes than uninformed group. Though the experiment shows that attention is vital for change detection, we should consider the size/ impact of the change in the environment. If the change to an environment is small, would it result in the change being detected? Do providing little clues draw attention effectively to where the change is being made? In support of this argument, Rensink (1997) showed that even with small clues, if the clue is not directed properly then detecting change will not have an effect. A proposal of Rensink is that the absence of attention will cause visual contents to be missed. On the other hand, Simon and Levin (1998) suggest that a person could miss things happening in their environment if his or her attention is occupied by something
