Change blindness provides a
new technique for mapping visual attention with unprecedented spatial and temporal resolution
. Change blindness can occur when a brief full-field blank interferes with the detection of changes in a scene that occur during the blank.
How does attention influence change blindness?
There are other factors that could influence change blindness, including attention,
age

What does change blindness tell us about perception and attention?

understanding attention
, perception and visual short-term memory (vSTM). … When changes were applied during blinks, subjects failed to notice a change even when they were looking at the positions of modified stimuli (looking without seeing).

selective attention
allows us to tune out unimportant details and focus on what matters. This differs from inattentional blindness, which is when you focus hard on one thing and fail to notice unexpected things entering your visual field.
Inattentional blindness is
the failure to notice a fully-visible, but unexpected object because attention was engaged on another task, event, or object
. … In most cases, studies of inattentional blindness involve a single critical trial in which an object appears unexpectedly while observers are performing their task.
What is change blindness and why is it important?
Change blindness refers to a
phenomenon in which large changes to the visual world go undetected if attention
is not already focused on the objects or area in which the change occurs. … In each of these cases of change blindness, it is clear that the focus of attention is an important predictor.
What is change blindness example?
The change blindness phenomenon can be demonstrated relatively easily by repeatedly presenting two pictures, let us
