P(z)P(z)P(z)Reasons for “invisibility”So, objects may be “invisible” for only 2 + 1 reasons;because the internal activity they yield upon presentation: is undistinguishable fromnoise (null sensitivity) d' = 0,0,50,40,30,20,1c =1.5d' = 30,50,40,30,20,10-4 -3 -2 -1 0 1 2 3 4 5 60-4 -3 -2 -1 0 1 2 3 4 5 6 is below Sj’s criterion the objet is ignored, or0,50,40,30,20,10-4 -3 -2 -1 0 1 2 3 4 5 6 because Sj’s report on the presence/absence of thestimulus is solicited within a time delay beyond his/hermnemonic capacity (the case of change blindness).
