PSYB57H3 Chapter 11: b57 - chapter 11 - VISUAL KNOWLEDGE
Document Summary
Francis galton: asked various ppl to describe their images and to rate them for vividness; so he asked them to introspect- to look within and report on their own mental contents. The self report data he obtained fit well w/ common sense; the participants reported that they could inspect their images much as they would inspect a picture. This implies a mode of representation that is picture like. Another founding is that his participants differed widely from e/o:, many described images of photographic clarity, rich in detail, as if they could see the object whereas others reported very sketchy images/none at all. Concerns: cannot take self reports for face value; participants may be seeing similar things but describing them differently. However if you were to draw a cat, you would include the head in the sketch, but not the paragraph. The pattern of what info is included depends on the mode of presentation.
