Document Summary
Memory representation that preserves visual and spatial information. Visual perception: a sensory impression in the presence of sensory input. Visual imagery: a sensory impression in the absence of sensory input. Mental images are created by the same mechanism that creates language (propositional mechanism) Mental images and perceptual images both involve visual and spatial analogues of the stimulus. Compare the brain area that are activated: when a person observed perceptions of actual visual stimuli (perception, when a person was imagining the stimulus (imagery) When perceiving and creating imagery of certain objects, there are great activity in the frontal areas. The patterns of both imagery and perception are fairly equal. The same is true between parietal and temporal areas as well, with negligible differences. However, the activity in the occipital lobe are somewhat different (occipital is responsible for sight) Words generally become more memorable when you associate them with images. Paivio: verbal (logogens) and nonverbal (images) processes are done differently.
