Conversations with Yourself makes you Smarter.

Talking to yourself is often looked at the behaviour
of crazy person, right?
No, according to a new study, which reveals that the
irrational act of speaking to oneself actually
improves cognitive boost and makes you smarter .
when you give
yourself verbal labels to a task you’re performing, you
focus better on the task at hand at any given moment. 
In a research by Gary Lupyan and Daniel Swingley, was inspired the pair’s experiences of seeing people audibly muttering to themselves when trying to find items on supermarket shelves. To test whether speaking to oneself was actually beneficial,  gary and daniel create a set of experiments. In one experiment,
volunteers were shown 20 pictures of everyday
objects of the same kind and asked to search out a
specific one. Initially participants were shown a piece
of text telling them which object to find and left to
complete the task in silence. Then, in subsequent
tests involving different objects, the participants were
asked to repeatedly say the name of the object they
were searching for. Across the board, the objects were
found more quickly when participants were speaking
to themselves.
