Driving with satellite navigation contributes to inattentional blindness

Satel­lite Nav­i­ga­tions Could Blind Dri­vers On Road (BioScholar):

Dri­ving with a satel­lite nav­i­ga­tion can make you blind to pedes­tri­ans, because try­ing to hold an image of the screen in your mind makes you ignore what is in front of your eyes, a new study has revealed. Focus­ing on the detail of some­thing we have just seen diverts our atten­tion away from things hap­pen­ing around us and results in an effect known as “inat­ten­tional blindness.”

  • Par­tial abstract: Load The­ory of atten­tion sug­gests that high per­cep­tual load in a task leads to reduced sen­sory visual cor­tex response to task-unrelated stim­uli result­ing in “load-induced blindness”…Consideration of the find­ings that visual STM (VSTM) involves sen­sory recruit­ment within Load The­ory led us to a new hypoth­e­sis regard­ing the effects of VSTM load on visual processing…We tested this hypoth­e­sis with fMRI and behav­ioral mea­sures of visual detec­tion sen­si­tiv­ity… Addi­tional visual detec­tion exper­i­ments estab­lished a clear trade­off between the amount of infor­ma­tion main­tained in VSTM and detec­tion sensitivity…
