Attention is the mental process of bringing few stimuli into the centre of awareness out of the many stimuli present.
It is not possible to divide attention to two tasks simultaneously. We can perform two tasks at the same time only if both of them are too simple or mechanical. If we try to pay attention to two tasks at the same time it may result in decreased efficiency and more confusion. Example: if a person has to read a passage from a book and thread a needle simultaneously, it wouldn’t be possible.
