Selective Attention and Irrelevant Stimuli

Attention is "to grasp the heart in a clear and vivid form, to get it from some things and ideas that may appear at the same time, to withdraw from something to effectively deal with others Meaning "(James, 1898)) Selective attention refers to the individual's focus on their consciousness for specific stimuli. This person can perform only one or more tasks at a time. This is necessary to prevent excessive personal information. One of the main functions of attention is selective hearing, which causes some irritation and ignores other stimuli.

Caution Assuming that the process is based on stopping mainly irrelevant stimuli, rather than doing extra things with related stimuli around us, we assume that the brain has all unrelated impulses (emotion, recognition You can understand the amount of energy needed to block the emotions. Change the impulse associated with the focus of attention. Certain mental disorders, such as anxiety and depression may affect the attention process - well-known common mental illness can seriously affect attention. It was once thought to be a disease mainly seen in childhood, but ADHD and ADD are becoming more focused on adult diseases than before.

Most of what is happening at any point in the world is irrelevant to current behavior. Caution is a psychological process of choosing relevant information according to the situation, suppressing irrelevant information, and switching these pieces of information. Selective processes are usually adjusted before the relevant information is displayed; this expectation can be selected quickly when significant stimuli become available. The majority of this research shows that birds, mammals, reptiles pay the same attention as humans.

Selective attention represents a combination of skills that allows you to focus on specific tasks, ignoring irrelevant stimuli. Simply put, it is the extent that you can choose the attention you have chosen. Often it's time to investigate how people can find target images (usually recognizable symbols such as letters) when distracted by images that are not other targets. The more the target resembles the interferer, the more difficult the task is. Alternatively, changing the ratio of target to non-targeted image also increases difficulty. To succeed, you need to concentrate on related content and ignore everything else.

CAUTION In blinking tasks, volunteers are asked to identify two "target" stimuli (eg, two specific numbers) with a quickly presented "non-target" stimulus stream (eg, a character unrelated to the task) Yes. When the first target number is displayed on the screen, the attention of the subject is captured and the second target will not be displayed within about 1/2 seconds of the first target (blinking attention). The second goal is unnoticed, as the brain can not handle the second goal, as the brain is busy dealing with the initial goal. However, paying attention to flickering does not constitute a bottleneck in structural processing. Most subjects can find the second goal at least for a small number of trials.
