To what extent is attention necessary for us to process information or perform a task Essay Example

others. This is because our conscious processing has limited capacity and needs to be selective to avoid information overload, as noted by Broadbent in 1958. When multiple messages are presented simultaneously, they gain simultaneous access to a sensory buffer. However, only one input is allowed through a filter while the others are held in the buffer to prevent overloading of the limited capacity mechanism.

The duration of time one can maintain concentration on a given task is known as attention span, which is an essential aspect of focus. Generally, most people possess an attention span ranging from 20 to 30 minutes. However, for individuals with ADHD - especially children - attention becomes even more crucial to consider as they struggle with processing information and completing tasks due to their inability to sustain focus. It's worth noting that this disorder affects a larger population than we may realize: around 3-5% of school-aged children and 2-4% of adults have been medically diagnosed with ADHD (Goldman LS, 1998).

For children who have difficulty with concentration, maintaining attention and interest in tasks may prove to be challenging. While they may apply focus during activities that appeal to them, performing homework or acquiring new knowledge can present obstacles for them.

Children with ADHD often encounter difficulties when it comes to completing their assignments. These challenges can range from forgetting materials at school or bringing home the wrong items, to frequently making mistakes that cause frustration for both the child and parent. Symptoms of ADHD include being easily distracted by irrelevant stimuli, failing to focus on details, making careless errors, and frequently failing to follow instructions. Furthermore, children with ADHD may have trouble

holding onto possessions such as toys, pencils, books and other essential tools needed for schoolwork. They may also find it tough to concentrate on one task without switching between multiple unfinished activities. While there are varying degrees of severity in different forms of ADHD diagnoses; they all significantly impact the daily lives of children who experience them.

Individuals with Inattentive ADHD may appear focused on their work and not exhibit impulsivity or hyperactivity, even if the case is less severe. However, they often struggle with maintaining focus and can experience confusion, daydreaming, sluggishness, and laziness. Additionally, they can have difficulty processing information as quickly and accurately as others despite receiving both oral and written instructions from teachers. As a result of this lack of attention, these individuals frequently misinterpret instructions and make mistakes which creates challenges for both adults and children.

The significance of paying attention is evident in many aspects of life. Neglecting to follow instructions in class can result in incorrect completion of assignments, while disregarding traffic signs can lead to accidents or tickets. ADHD illustrates the importance of attention for optimal brain function, whether it's remembering to bring a book to class or writing an essay. This condition highlights the contrast between individuals who are capable of focusing and those who aren't. While I've researched how ADHD affects attention spans in children and adults, it's crucial to recognize how attention impacts daily activities like driving. The level of attentiveness required when behind the wheel varies based on driving conditions; for example, navigating a two-lane street demands more focus than driving on a highway.

Driving on curved roads requires greater attention than driving on straight ones,

but as drivers gain experience they can adapt and require less focus. With increased comfort comes a change in information processing, where certain processes become automatic. This is why drivers feel more at ease with their vehicle after gaining experience compared to when they first started.

As processes become automated, the necessary amount of attention decreases significantly. This indicates that, while initial attention is crucial, we eventually learn to do the task with less attention required. In driving, assessing visual attention is crucial since the driver relies largely on visual information. Drivers tend to use 30-50% of their visual attention off the road because of possible distractions, such as bright lights or moving objects. Though these distractions are usually brief and do not affect the driver, studies conducted by Dingus and Hulse (1993) suggest that more noticeable distractions can have far more dangerous consequences. Occasionally, drivers may fixate too long on an object, which could be harmful depending on how much visual attention is required for safe driving. According to Dingus, the visual attention needed for driving can change abruptly at any given moment. As a result, designers consider the length and level of concentration needed for any information utilized by drivers.

A visual display that demands prolonged and recurrent attention may impede satisfactory monitoring of the driving setting. The ability to focus can differ among people due to conditions like ADHD, which hinder the brain's use of attention. Consequently, these disorders indicate that the brain encounters difficulties in processing data on both conscious and subconscious levels. This highlights the significance of attention in information processing and task execution. Nevertheless, those with such ailments can still process

information but have limitations on focusing only on things that capture their interest.

The impact of ADHD on task performance is substantial in comparison to those without the disorder. Whereas individuals without disorders can effortlessly complete unenjoyable tasks, individuals with ADHD may struggle even with simple tasks, particularly when focus is required, like driving a car. The risk of accidents increases for easily distracted individuals as they are more likely to be unaware of their surroundings. Moreover, research indicates that distractions occur more frequently when multiple thought processes are happening simultaneously, emphasizing the significance of attention in safely completing tasks.
