Divided attention, also known as multitasking, is when we focus on more than one task simultaneously. Imagine you are cooking while listening to a podcast. Both activities require your cognitive resources. These resources are limited, so when they are split across multiple tasks, each task may receive less attention.

Common examples of divided attention include:
- Talking on the phone while driving.
- Listening to music while studying.
- Checking notifications while in a meeting.
Our ability to divide attention efficiently can vary based on the complexity of the tasks and our familiarity with them. For example, an experienced driver might find it easier to talk and drive compared to someone still learning.

Selective attention is our ability to focus on a specific task or stimulus while ignoring other distractions. Think of it as using a spotlight to highlight what’s important, leaving other things in the dark. For instance, when reading a book in a noisy cafe, selective attention allows you to concentrate on the words and block out the surrounding chatter.

Some everyday scenarios of selective attention include:
- Focusing on a teacher’s lecture while other students are talking.
- Listening to your friend in a crowded party.
- Watching a movie without getting distracted by external noises.
This type of attention helps manage cognitive resources efficiently by dedicating energy and mental capacity to one primary task or stimulus.

Cognitive resources refer to the mental energy and capacity we have to process information, make decisions, and solve problems. These resources are finite, which means we can only handle so much mental workload at a time.

Factors that affect cognitive resources include:
- Fatigue: Tiredness can reduce our mental capacity.
- Stress: High stress levels can tax our cognitive resources, making it harder to focus.
- Task complexity: More complex tasks require more cognitive resources.
Efficient use of cognitive resources is crucial for performing tasks effectively. For instance, when engaging in divided attention, cognitive resources are split between tasks, potentially reducing performance in each. On the other hand, selective attention allows us to allocate most of our cognitive resources to a single task, often resulting in better performance.
