Peradventure you are passing through hundreds of books without actually noticing any of them. On the other hand, your optics actually run into all of them and possibly record them deep into your heed, merely you lot don't even realise it. This here is a keen selective attention example.
Now that you have an agreement of the concept, let's go over the selective attention definition.
What is Selective Attention?
If nosotros need to define selective attention we can call it the process of focusing on a particular object in the environment for a certain menstruum of time. Our attention is limited.

Examples of Selective Attention
Cocktail Party Issue
As we've mentioned before, although there are many stimuli around in crowded and noisy environments such as parties, our encephalon selects certain stimuli and focuses on them.
The Monkey Business
Every bit in the most famous selective attention exam, "Gorilla Business" that nosotros'll mention farther on in our commodity, if you accept a specific target to focus on, your brain just follows your target. So it doesn't notice whatever other unusual stimuli. Here is a version of Gorilla Business organization:
Visual Selective Attention
Perhaps we are exposed to millions of ads every twenty-four hour period on the way to work or on the road. Nosotros don't even realize that we've seen many of these. But some, on the other paw, manage to attract our attending, especially if they address our current needs or taste.

Play Brain Grooming Games
Selective Attention Test
In the Invisible Gorilla experiment conducted past Simons and Chabris in 1999, a video is shown to the participants. In the video, two separate groups of people, one in black shirts and the other in white shirts, pass the ball to each other. Participants are told to count the number of times the players in white shirts passed the ball.
In the middle of the game, a gorilla enters the screen. He walks through the players, stands in the middle, hits his breast, then walks off the screen once again.
"Did you encounter the Gorilla?" At the end of the video, when asked, it turns out that more than one-half of the subjects did non even notice the gorilla.
Based on this experiment, it is possible to say that nosotros missed most of what is happening around us and that we have no idea near all these events and stimuli that nosotros missed before we even realized.
How Does Selective Attention Work?
The term "cocktail party event" is also used to describe selective attention psychology, especially in the Memory Option Model. Because while nosotros're at a political party, in that location are many things that can distract u.s.a. like music, light, and many other people talking. However, we tin nonetheless focus on one conversation with a close friend. On the other hand, when our name is called among all the intense stimuli in this groundwork, this will grab our attention.
So which of the following is the reason for human attention being selective?
Information technology is proven that the capacity of our brains to accept care of everything around united states is very limited, so it is impossible for us to pay attention to each of these sensory experiences. Therefore, while our brain focuses our attention on some important elements of our environment, it puts all other stimuli in the background.
Theories of Selective Attending
In cerebral psychology, at that place is more than i selective attention theory, which is focused on when our brains react and interact with stimulating data from exterior.
Broadbent Filter Model
This model was defined past Donald Broadbent in 1958. He used a filtering metaphor of data processing to describe attention. Broadbent suggested that our filtering of information occurs early on in the perceptual process. Physical characteristics similar colours, loudness or direction of the stimulants processed before were used to select or reject a stimulus in afterward operations.
Treisman'south Attenuation Theory
Treisman proposed in his selective attending theory that instead of the filtering method specified by Broadbent's model, attention works by using an attenuator that defines a stimulant based on physical properties or meaning.
Yous can think of the attenuator equally a controller or selective filters. You can mute other stimulus sources to join a single stimulus. Although the intensity of other stimuli is low, they still exist.
Memory Pick Models
According to the Retention Selection Model, the stimuli that nosotros volition pay attention to and the stimuli that nosotros will not pay attending to pass through the first filter. It is then ranked in the 2nd stage according to the actual meaning of the message content. Stimulants, which attract our attending by passing through the meaning criteria are transferred to curt-term memory.
Resource Theories of Selective Attending
More than recent theories suggest that human attention can interact with express stimuli and tends to explain how these resources are divided amid competing stimuli. Hence, source theories appear to be a much more than effective metaphor to explicate the phenomenon of attention divided into complex stimuli and tasks.
ADHD and Selective Attention
ADHD and selective attending are closely related equally parents of children with ADHD notice that their kids hesitate and don't give their attention to complete tasks such as homework or chores while spending hours after hours focused on other fun and enjoyable activities.
This situation leads parents to assume that their children are willfully delaying harder tasks or fugitive their responsibilities equally they don't have a full agreement of why their children tin can focus on one action and not some other.
Children with ADHD tin can focus more hands on activities that they enjoy considering they provide more stimulation for their brains. For instance, computer games provide increased auditory and visual stimulation which are elements that are attractive to children with ADHD as their brains run across all of their stimulation needs.
On the other paw, activities such as homework or chores provide less stimulation, and so the encephalon continues to search for other ways to stimulate itself. Equally a issue, children with ADHD are decumbent to "selecting" stimulating tasks over less stimulating ones.
Selective and Divided Attention Comparison

| Excellence in tuning out distractions and switching tasks | Trouble in tuning out distractions and switching tasks |
| Strengthens cognitive power | Weakens cognitive ability |
| Reduces the rate of making mistakes | Improves the rate of making mistakes |
| Higher in people with ADHD | Lower in people with ADHD |
| May cause missing important side information | Prevents missing important side data |
