Answer:
sustained attention
Step-by-step explanation:
Sustained attention is the ideal type of attention for those who need to stay focused for a long time, as this is the ability to stay focused for a long time on uninterrupted and constant activity. An example of this kind of attention is shown in the question above, where Karl manages to pay attention to everything that happens outside his living room window. Karl's attention is uninterrupted and he can stay focused for a long time.
People with Sustained Attention can, for example, remain attentive in lectures, courses, training, workshops, during school classes and in their moments of study, leaving aside any kind of distractions that try to hinder them.
In many cases, sustained attention is closely related to selective attention, as many situations require us not only attention itself but to remain focused on a specific activity over a long period of time, without other factors get us out of this focus.
