Document Summary

Chapter 4 mental imagery: mental imagery processing of perceptual like information in the absence of an external source for the perceptual information. Same brain areas are activated when they actually see or speak. Subsequent brain imaging studies determined that the parietal brain region is activated in mental rotation tasks: area specialized for spatial attention, also fou(cid:374)d that i(cid:373)agi(cid:374)g the (cid:396)otatio(cid:374) of o(cid:374)e"s ha(cid:374)d p(cid:396)odu(cid:272)ed a(cid:272)ti(cid:448)atio(cid:374) i(cid:374) the (cid:373)oto(cid:396) (cid:272)o(cid:396)te(cid:454) This task produced greater impairment in the image scanning task: people suffer from interference in scanning a mental image if they have to simultaneously process a conflicting perceptual structure. Judgment time decreases with increased difference in the size of the two animals. Subsequent experiments where participants judge which one of two lines is longer shows the same result. People experience greater difficulty judging the relative size of two pictures or two different mental images that are similar in size.
