CLOSELY!
The human brain is able to
completely miss a fully-

3. 1. Change Blindness: the inability to detect a change in an object or a scene.
 The difference between the phenomena is that inattentional blindness is
the inability to detect a new and unexpected object.
Causes of Inattentional Blindness
1. Conspicuity: Is it attention-grabbing?
2. Mental Workload: A lot on your mind?
3. Expectation: What did you expect?
4. Capacity: Expert vs. Novice- how
much attention is required?
(Hannon & Richards, 2012)

4. 2. Selective Attention: responding selectively to certain sources of
information while ignoring other sources.
 Inattentional blindness also illustrates a critical aspect of visual processing.
Specifically, it reveals the role of selective attention in perception.
 Inattentional blindness represents a consequence of this critical process that
allows us to remain focused on important aspects of our world without distraction
from irrelevant objects and events.

6. Research shows that there is a relationship between
inattentional blindness and action-demanding team
sports.
o More tactical instructions can lead to a narrower
breadth of attention, which increases inattentional
blindness, whereas fewer tactical instructions widen
the breadth of attention in the area of team ball sports
and therefore decreases inattentional blindness.
(Furley & Memmert, 2007)

7. Research shows that attending to music decreases
inattentional blindness.
o Listening to music will decrease inattentional
blindness by reducing observers' frequency of task-
unrelated thoughts, this was due to the distracting
qualities of the audio task
