What is inattention blindness quizlet?
Inattentional Blindness.
The failure to notice a fully visible, but unexpected, object or event when attention is devoted to something else
.
What is the cause of inattentional blindness?
Inattentional blindness (also called perceptual blindness) is the failure to notice something that is completely visible because of a lack of attention. … A want of either sensory conspicuity or cognitive conspicuity, a lower working memory capacity, and
a higher mental workload
may cause inattentional blindness.

What is the importance of change blindness?
Change blindness is
a phenomenon where subjects fail to detect even a large change in the visual scene
. Studies on change blindness have proved useful for understanding attention, perception and visual short-term memory (vSTM).
How is attention said to help us see objects?
Attention is a
tool to adapt what we see to our current needs
. It can be focused narrowly on a single object or spread over several or distributed over the scene as a whole. … Flexible use of these different modes of attention allows us to reconcile sharp capacity limits with a richer understanding of the visual scene.
What is selective attention in psychology?
Selective attention refers to
the processes that allow an individual to select and focus on particular input for further processing
while simultaneously suppressing irrelevant or distracting information.
Why research attention is necessary?
Attention plays a critical role in almost every area of life including school, work, and relationships. It
allows people to focus on information in order to create memories
. It also allows people to avoid distractions so that they can focus on and complete specific tasks.
How does selective attention cause some evidence to be overlooked?
Attention is a limited resource, so 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.
Why is visual attention important?
As we observe the environment around us, that information is stored in our working memory, so that we are aware of
potential hazards
around us. This sort of focus allows us to perform everyday tasks, such as walking and driving, without injuring ourselves.
How are we affected by selective attention?
How are we affected by selective attention?
attend to, and process
, an extremely small amount of incoming information, while blocking out most of the other information. We also shift our focus (attention) from one thing to another during this process.
When we are focused on one thing we may not notice that something else that we can see but are not thinking about is changing as well this is an example of?
This phenomenon is now known as
inattentional blindness
, the surprising failure to notice an unexpected object or event when attention is focused on something else (Mack & Rock, 1998).
Which nerve carries visual information from the retina to the brain?
Rods are on the periphery of your retina. They process low levels of light and motion; cones, mainly in the center of your retina, distinguish color and detail.
Optic nerve
: This cranial nerve sends visual information from your retina to your brain. It consists of more than 1 million nerve fibers.
What is the difference between selective attention and inattentional blindness quizlet?
Our selective attention allows us to focus on only a limited portion of our surroundings. Inattentional blindness
explains why we won’t perceive some things when we are distracted
.
Why is sustained attention important?
Sustained attention is
the ability to focus on an activity or stimulus over a long period of time

What is the bottleneck theory of attention?
The bottleneck theory suggests
that individuals have a limited amount of attentional resources that they can use at one time
. Therefore, information and stimuli are ‘filtered’ somehow so that only the most salient and important information is perceived. This theory was proposed by Broadbent in 1958.
What impairment would you expect to see in an individual with damage to their primary visual cortex?
Destruction of the primary visual cortex leads to
blindness
in the part of the visual field that corresponds to the damaged cortical representation. The area of blindness – known as a scotoma – is in the visual field opposite the damaged hemisphere and can vary from a small area up to the entire hemifield.
When you are able to recognize and image despite a challenging and distracting background is called?
The ability to identify a stimulus when it is embedded in a distracting background is called
signal detection theory
.
What is focused visual attention?
Visual attention refers to
the ability to prepare for, select, and maintain awareness of specific locations, objects, or attributes of the visual scene
(or an imagined scene). The focus of visual attention can be redirected to a new target either reflexively or through the purposeful effort of the observer.
Why is Dichotic listening important?
Dichotic listening tests are used in clinical
audiology to evaluate the central auditory processes of binaural integration and separation
. These tests may be used in the assessment of children or adults with possible central auditory nervous system dysfunction.
Why do we fail to perceive stimuli?
We sometimes fail to perceive stimuli during
change blindness because we are unaware of our environment changes
, therefore, we fail to perceive the recognition of environmental stimuli. … absolute threshold is the minimum stimulation needed to detect a particular stimulus, or our senses, 50% of the time.
What factors affect attention?
- Intensity: the more intense a stimulus is (strength of stimulus) the more likely you are to give attention resources to it.
- Size: the bigger a stimulus is the more attention resources it captures.
- Movement: moving stimuli capture more attention that ones that remain static.

What is bottom up in psychology?
Bottom-up processing is
an explanation for perceptions that start with an incoming stimulus and working upwards until a representation of the object is formed in our minds
. … It is in the next step of the process, known as perception, that our brains interpret these sensory signals.
What is subliminal perception?
the registration of stimuli below the level of awareness
