Document Summary
Various practical problems seem to evoke images but mental pictures cannot be actual pictures. Francis galton asked people to describe their images and rate them for vividness. In the self report data, participants reported they could inspect their images as they would a picture. Viewing images from a certain position and distance. Implies mode of representation that is picturelike. Varied in terms of photographic clarity suggesting that people differ in the nature of their imagery. There is a translation step involved when people translate their subjective inner experience into a verbal report and there"s no guarantee that everyone translates in the same way. Need a more objective means of assessing imagery than self report. Chronometric studies: what sorts of info are prominent in a mental image and what info are not; evaluations used as a basis for asking how picture-like mental images really are.
