                2.7.4.3     Managing attention - automatic or controlled process?

                One can read written material in ways that are either automatic or controlled.

                Reading is automatic (i.e., quick and unconscious) when external stimulation

                governs attention. This is exogenous attention.




                In other cases, attention control may be controlled and volitional, meaning the

                attention  is  directed  by  the  person.  This  is  a  relatively  slow  process,  partly

                conscious, and requires a larger amount of attention resources.


                This is called endogenous attention.




                Thus, exogenous  attention is  what is  used  when one directs attention to a

                sudden flash of lightning in the sky.


                On the other hand, if one is looking at the sky to spot a particular star formation,
                one is controlling one’s attention; this is endogenous attention.
