this wiki        Attentional shift (or ) is an aspect of
attentional control and cognitive flexibility which in turn are
aspects of executive functioning and of cognitive ability.
A shift of attentionoccurs when directing attention to a point
to increase the efficiency of processing that point and includes
inhibition to decrease attentional resources to unwanted or
irrelevant inputs.[1] Shifting of attention is needed to
allocate attentional resources to more efficiently process
information from a stimulus . Research has shown that when an
object or area is attended, processing operates more
efficiently.[2][3] Task switching costs occur when performance
on a task suffers due to the increased effort added in shifting
attention.[1] There are competing theories that attempt to
explain why and how attention is shifted as well as how
attention is moved through space.      Unitary Resource and
