The difference between attention shift, attention distraction and attention allocation in psychology

Attention Shift: Shifting from the current task to another task. \x0d\This is a purposeful diversion. For example, the teacher asks you to read a book in class, and then asks you to do homework. \x0d\The attention shifts from reading to doing homework. \x0d\Distraction: Attention is diverted from the current task. \x0d\The teacher asked you to read and do your homework, but you were chatting and texting. \x0d\Attention has left the current task. \x0d\Attention allocation: Pay attention to 2 or more things at the same time. \x0d\For example, while playing a musical instrument and singing at the same time, the hands and mouth are controlled by the protagonist at the same time, and work together to complete the current task. The more that can be allocated, the better the coordination and control of attention will be. Of course, there are times when it cannot be allocated. \x0d\For example, if you draw a square with one hand and a circle with the other, the result is usually neither square nor round. Or, if two people speak to you at the same time, you can only choose one to hear clearly. Only one task can be attended to within the same receptor.
