L'attention sélective est un mécanisme cognitif essentiel qui permet au cerveau de se concentrer sur des tâches spécifiques tout en filtrant les distractions. Les interventions thérapeutiques contribuent à renforcer cette capacité grâce à des techniques fondées sur des données probantes, telles que l'entraînement à la pleine conscience et les stratégies cognitivo-comportementales.
Vous avez déjà remarqué que vous pouvez faire abstraction d'un café bondé, mais que vous êtes très attentif lorsque quelqu'un mentionne votre nom ? C'est l'attention sélective qui est à l'œuvre - la remarquable capacité de votre cerveau à filtrer ce qui est le plus important. La compréhension de ce puissant mécanisme mental peut vous aider à maîtriser votre concentration et à prospérer dans notre monde rempli de distractions.
What Is Selective Attention?
Selective attention involves the act of focusing on a particular object for some time while simultaneously ignoring distractions and irrelevant information. Multitasking is everywhere you look. People are often encouraged to do multiple things at once: watch television while they exercise, listen to music while they study, glance at their GPS while they drive. Over and over, we see instances in which we are encouraged to focus on multiple things at once, rather than focusing on a single task at hand. But is successful divided attention really possible? And if so, is it good to do?
Attention and diversion
Parents often implore their children to “please listen” or “pay attention” while they are staring down at their phones. Teachers tap against the blackboard to garner the attention of students who are gazing out the window or doodling on notebook paper. In each of these situations, the assumption is that a person cannot focus their attention on two tasks at once, and one task must be sacrificed to see the other to completion. The human mind, however, can be far more complex than that.
How the brain allows for selective attention
The human brain is made up of millions of neurons and neural pathways, each of them designed to help you carry out everyday tasks, such as doing your job, brushing your teeth, or driving to work.
Attention is not as simplistic as only being able to focus on a single task at a time, but research suggests that the human brain also isn’t capable of fully committing to multiple tasks simultaneously. Instead, the mind possesses the ability to engage “selective attention,” which allows people to divert attention and information processing resources to a certain task for a time before moving back into a state of greater awareness and a more engaged periphery.
What is selective attention?
Selective attention is defined by the American Psychological Association as “concentration on certain stimuli in the environment and not on others, enabling important stimuli to be distinguished from peripheral or incidental ones.”
Tuning in and tuning out: The act of focusing on a particular object for some time while simultaneously ignoring distractions and irrelevant information
When heavily concentrated on untangling a knot, for instance, the brain might engage selective attention and lose the ability to hear background noise or even noise as distinct as one’s name. It also manifests as intense focus on some sounds over others, such as tuning in to a conversation at a busy event—this is also called the cocktail party effect. Selective attention is the mechanism responsible for allowing you to hear the cry of a child over the noise of running water or the clinking of dishes.
The filter model
The filter model posits that selective attention is an involuntary response in your brain that functions as a filter; rather than being incapable of multitasking, the brain uses cues to identify which multitasking elements are most important and diverts its attention to those things. This filtration system tends to be fluid and move in and out of its tasks seamlessly. Your attention is constantly multitasking and taking in information, and your brain’s selective attention mechanism filters which stimuli or tasks are the most critical at any given time.
Why is selective attention important?
Selective attention typically allows the human brain to function more efficiently. Just as a computer gets slower when numerous windows, tabs, and programs are open, the human brain might quickly and easily become overloaded without selective attention. Selective attention can function as a filter to keep the brain working optimally as it goes about its tasks.
Life without selective attention
The loss of this function can also be impactful; being easily diverted or experiencing difficulty concentrating may be a sign of a breakdown in the mind’s ability to engage its selective attention mechanism. If the breakdown is temporary, you might not even notice the loss, but if your mind continues to struggle to use its selective attention abilities over a long period, work, school, and home lives can all reap negative consequences.
A tool for staying on track
Selective attention can also serve as a mechanism to ensure important tasks are completed. Selective attention often allows your mind to prioritize your needs—which can be an invaluable tool in accomplishing goals, keeping you safe, and performing basic tasks. Selective attention might alert you to the terrified cry of a child while you are busy with a task at home, encouraging you to abandon your work in favor of checking on your child. Selective attention can be vital to both seemingly menial tasks and survival-based ones.
How does selective attention work?
Selective attention is thought to be (at least) a two-step process whereby the brain takes in all of the information it sees and hears and sends it to a filtering system, which then identifies which stimuli are most important. The human brain is filled with processes, each of them able to perform multiple tasks. Selective attention is an example of these synapses and neurons performing multiple functions and filtering the information the brain receives.
Different parts of the brain working together
Certain parts of the brain are responsible for recognizing sight, patterns, and up-close experiences, while others are responsible for auditory signals. Still, others are responsible for “big picture” things and can take in more background noise. Each of these parts of the brain works in tandem to identify which aspects of the input your brain is receiving are important and which are acceptable to deprioritize.
Selective attention in therapy and mental health
Understanding selective attention has significant implications for mental health and therapeutic interventions. When clients work with ReachLink’s licensed clinical social workers, they often learn techniques to improve their selective attention capabilities, particularly in situations where attention difficulties are impacting daily functioning.
