Driving with satellite navigation contributes to inattentional blindness

Study: Visual Short-term Mem­ory Load Reduces Retino­topic Cor­tex Response to Con­trast (Jour­nal of Cog­ni­tive Neuroscience)

  • 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…
