Answer:
What is divided attention?
Divided attention could be defined as our brain's ability to attend to two different stimuli at the same time, and respond to the multiple demands of your surroundings. Divided attention is a type of simultaneous attention that allows us to process different information sources and successfully carry out multiple tasks at a time. This cognitive skills is very important, as it allows us to be more efficient in our day-to-day lives.
Our ability to attend to multiple stimuli and do various tasks at a time does have its limits. When you divide your attention, the efficiency with which you do these actions is decreased, and you will almost certainly perform poorly. Interference is the term used to describe when a person has a hard time attending to two stimuli at a time. We see interference when the brain is only able to process a certain amount of information. However, cognitive training can help improve divided attention, and as a consequence, the ability to do more than one activity at a time.
Examples of divided attention
Divided attention is an important factor in the academic setting. Being able to understand what the teacher is saying while reading the board and taking notes are tasks that are essential to successful learning. This may be one of the reasons why people with attention disorders (like ADHD) perform poorly in school.
A truck driver is driving on the highway and starts passing someone. As they are passing, they see a sign for their exit. If the driver isn't able to safely pass the other car and pay attention to traffic signs, they may lose important information, or even cause danger to themselves and others. Divided attention is very important to driving safely and successfully.
A waiter must use their divided attention when attending to a table. They have to remember what the man at table 4 wanted, write down table 3's order, and be careful to balance the plates of food that they're holding.
If a customer asks about the sales when paying at the cashier, the cashier has to scan and bag the items while thinking about the answer to the question.
When you're eating and talking at the same time, or even when you're watching TV and talking on the phone, you are using divided attention.
Disorders or pathologies associated with divided attention
Divided attention may be altered in a number of different disorders, whether it be due to problems with divided attention itself, or problems with other attentional sub-processes. For someone with poor divided attention, any interference may alter the task that they are doing simultaneously. If your divided attention is altered, you'll have a harder time pulling into an intersection and talking at the same time, and thus have a higher risk of having an accident. If Arousal is altered (the level of activation or general alertness), and you are in a comatose state, you will also be unable to talk and drive at the same time.
While divided attention may be affected by psychiatric conditions, like schizophrenia or various disorders like Attention Deficit Hyperactive Disorder (ADHD), it most affects general attention. It is also quite common to have attentional problems after suffering from a Traumatic Brain Injury (TBI), or stroke. In these cases, the attentional alteration and its sub-components may vary, depending on the affected brain areas.
