The Process of Selective Attention

The process of selective attention is an important process that affects how we process information. Initially, the theory of selective attention was developed by Deutsch, who hypothesized that sensory input is quickly forgotten if it does not have a personal pertinence. They later elaborated this model, suggesting that pertinence and strength of input determine the level of selection.

ACC recruitment

Several studies have shown that ACC recruitment is influenced by attentional direction. However, they did not demonstrate a horizontal bias. One study found that attentional direction affected ACC recruitment in the face between conditions. This effect could be corrected by varying the orientation of the attentional cue.

The findings from this study suggest that ACC recruitment depends on the cortical mechanisms that regulate the activity of the ACC. These findings provide an important framework for investigating the mechanisms underlying selective attention and its development. Specifically, researchers have identified three sets of questions that have been central to their investigations. These questions include the modulation of information processing, the mechanisms underlying the deployment of selective attention, and the effects of competing stimuli on attention.


Attenuation of selective attention (ASA) is a process in which an individual modifies the flow of information in the brain. Such modulations are thought to originate from the neural systems and are guided by bottom-up signals, salient information, and the goals of the participant. Several studies have shown that attentional modulation occurs throughout the brain, with the effect being most apparent in the earliest areas.

Some aspects of attention are present in early infancy, and the ability to deploy selective attention is still developing into early adulthood. However, there is evidence to suggest that the effect of selective attention is diminished in children who are exposed to background noise.


Timeboxing is a way to manage time in which you focus only on a single task at a time. This method works by removing distractions from a task by setting a time limit and assessing whether you have achieved your goal. For example, you may have set yourself a time limit to write 400 words or clean your attic. However, you were interrupted mid-task.

To implement timeboxing, you must define stated goals that you want to achieve in each sprint. Once the team has agreed to these goals, the time boxing process can be implemented. The time constraint is a powerful way to focus attention, forcing a team to periodically evaluate their direction and make course corrections.

Bottleneck models

Bottleneck models of selective attention are models that explain the bottleneck in processing sensory input. These models are based on studies involving human subjects. They explain the phenomenon of selective attention by claiming that the brain can only focus on a limited number of channels at a time. This model was first proposed by Broadbent (1957) before the development of pattern recognition.

Deutsch and colleagues derived a similar model of attentional bottleneck. Both models propose that the brain must attend to information in a specific time period before the brain can attend to a new stimulus. However, the location of the bottleneck varies between the two models.
