The early selection model of attention, proposed by Broadbent,
posits that stimuli are filtered, or selected to be attended to
, at an early stage during processing. A filter can be regarded as the selector of relevant information based on basic features, such as color, pitch, or direction of stimuli.
What are the theories of attention in psychology?
According to the
attention schema theory
, the brain constructs a simplified model of the complex process of attention. If the theory is correct, then the attention schema, the construct of awareness, is relevant to any type of information to which the brain can pay attention.
What is attention theory?
In many theories, attention is
the link between perception and memory
: the amount of attention devoted to an event at the time it occurs (i.e., at encoding) is a good predictor of the likelihood that it will be consciously remembered later (i.e., at retrieval).
What is filter attenuation theory in psychology?
a version of the filter theory
of attention proposing that unattended messages are attenuated (i.e., processed weakly)
but not entirely blocked from further processing.
Is attention a selective filter?
Selective attention is the
process of focusing on a particular object in the environment
for a certain period of time. Attention is a limited resource, so selective attention allows us to tune out unimportant details and focus on what matters.
What is called as mother of attention?
Sustained attention is also commonly referred to as
one’s attention span
. It takes place when we can continually focus on one thing happening, rather than losing focus and having to keep bringing it back.
What are the 3 types of attention?
- Arousal: Refers to our activation level and level of alertness, whether we are tired or energized.
- Focused Attention: Refers to our ability to focus attention on a stimulus.
- Sustained Attention: The ability to attend to a stimulus or activity over a long period of time.
What are the various theories of attention?
A “hugely influential” theory regarding selective attention is the perceptual load theory, which states that there are two mechanisms that affect attention:
cognitive and perceptual
. The perceptual considers the subject’s ability to perceive or ignore stimuli, both task-related and non task-related.
What is load theory of attention?
Load Theory (Lavie, 1995, 2005) states that
the level of perceptual load in a task
(i.e., the amount of information involved in processing task-relevant stimuli) determines the efficiency of selective attention. … The current study is the first to assess the effect of perceptual load on eyewitness memory.
What is Broadbent’s theory of attention?
Broadbent’s theory predicts
that hearing your name when you are not paying attention should be impossible because unattended messages are filtered out
before you process the meaning – thus the model cannot account for the ‘Cocktail Party Phenomenon’.
What is an example of divided attention?
Divided attention is the ability to pay attention to two tasks at once such
as cooking a meal while talking to a friend or driving a car and talking to a passenger at the same time
– neither activity is stopped in order to carry out the other activity.
How do we pay attention?
By
shifting
our gaze, we bring the object of interest into our fovea, which is an area of very high sensitivity in the center of our retina. However, experiments show that even without moving our eyes, we can still pay attention to any place or any object, wherever it is, and amplify its features.
What are some real life examples of selective attention?
- Listening to your favorite podcast while driving to work.
- Having a conversation with a friend in a crowded place.
- Reading your book on a public transport bus.
What is the filter theory of selective attention?

What are the benefits of selective attention?
Selective attention
allows adults to focus on task-relevant information, while ignoring task-irrelevant information
. This in turn leads to superior processing of task-relevant information. However, this advantage comes at a cost: Adults encode only a small subset of presented information.
Is selective attention good or bad?
Selective attention
is important
because it allows the human brain to work more effectively. Selective attention acts as a filter to ensure that the brain works best in relation to its tasks.
