Taking instances and hints from Kahneman's Capacity Model of Attention, it can be said, for example, that a driver who interrupts a conversation makes a turn. Kahneman, in his theory, said it is a capacity theory of attention, which means that attention is not an infinite resource but rather a shared resource. One more example from this theory is that a person reading a book will surely look in the other direction, in a natural process, if a doorbell rings during that particular time. Kahneman also stated that it is a very subjective process that also depends on the reflex action of an individual. Thus, in both the stated examples, it can be seen that attention requires basic importance and effort from the other person providing the attention. Kahneman, in his theory, stated that effort is a cognitive activity that ends up in the situation of attention.
A capacity model is used to determine and predict the operation's future staffing needs to meet your end users' or customers' incoming volume needs. A workforce management team is usually in charge of this task. Mainly with the help of a Capacity Model, one can easily understand the consequences that each and every action possesses within it. It is a helpful process in identifying and observing any individual's characteristics and traits. Capacity theories, such as the one proposed by Kahneman in the early 1970s, started with the assumption that human information-processing capacity is limited and proposed that the ability to perform one or more tasks was dependent on both the resources available and the resources required by the tasks. The capacity model consists of three basic components. These are
Processing of the education content.
Processing of the narrative content.
The distance exists between educational and narrative content.
According to Kahneman's Theory or Model of Attention, it can be stated that every instance of attention is a manifestation of effort, and every manifestation of effort is a manifestation of attention. This distinction between effort and attention appears to be a subset of cognitive activity, which is attention. A capacity theory of attention offers an alternative to theories that explain man's limitations by assuming structural bottlenecks exist. Instead of such bottlenecks, a capacity theory assumes that man's capacity to perform mental work has a general limit. According to Kahneman, his theory is a capacity theory of attention, which means that:
Attention is not an infinite resource
attention is a shared resource.
The first interpretive inference that can be drawn from Kahneman's theory of effort is that it differentiates between mental and physical effort. However, the mental/physical distinction is becoming somewhat obsolete, as most researchers now refer to the cognitive rather than the mental, assuming that the cognitive has a physiological basis in the nervous system. Mental can be misinterpreted as a dualist view of the spiritual mind as distinct from the physical body. It will now be referred to as cognitive effort rather than mental effort.
As a capacity theory of attention, according to Kahneman, attention (1) is not a limitless resource, and (2) is a shared resource. When two things are claimed to be identical, they are one thing rather than two—they are logically interchangeable. Thus, every instance of attention is an instance of effort, and every instance of effort is an instance of attention, according to Kahneman's theory. This distinction between effort and attention appears to resolve Q2—effort is a subset of cognitive activity, which is attention. However, Kahneman does not regard attention as a distinct type of cognitive activity. The fact that effort-attention5 is a shared resource is central to Kahneman's capacity theory. As a result, it cannot be limited to a single area of the brain or anatomical network. Only by viewing attentional network theory as a kind of pipeline channeling resources or as a network facilitating resource utilization rather than as a specific site or activity of resource utilization could Kahneman accept it. Because nerves activate metabolic energy rather than channel it, the best physiological way to understand Kahneman's idea is to postulate that effort-attention is a shared resource regarding blood flow and energy activation within cells, activated by neural networks. Based on a clear understanding of brain physiology, only blood flow can be a shared energy resource in the brain. The concept of effort-attention does not apply to a specific type of cognitive activity but to any cognitive activity reached by an activating network. Although Kahneman claims that it is not difficult for a researcher to distinguish between arousal as effort-attention and other "contaminating factors," he does not provide any objective measure, leaving Q5 unanswered.
The Theory of Capacity Model of Attention by Kahneman is somewhat related or linked with the divided attention model proposed by Kahneman.
Kahneman's model of divided attention proposes an attention model based on the concept of mental efforts. This describes how difficult it may be to process a specific input. Despite having a high information load, some tasks may be relatively automatic (requiring little mental effort). As a result, Kahnemann proposes that:
Some activities are more demanding and thus require more mental effort than others.
Other factors, such as arousal, can increase or decrease the total available processing capacity.

The capacity theory is the approach that drew researchers away from Filter theories with Kahneman's 1973 study, Attention, and Effort, posited that attention was limited in overall capacity and that a person's ability to perform simultaneous tasks depends on how much "capacity" the jobs require.
