Document Summary
Image demons convert proximal stimuli into representations: feature demons looking for a different particular feature. Answer: demons respond loudly or quietly depending on how confident they are, which will be impacted by the clarity or quality of the stimulus. Answer: in a prototype matching model, a percept is compared to idealized representations in memory of every class of information, and matched to the one it most closely approximates. Implies that visual precepts are not precise copies of our visual world: reinforces the idea that perception is driven by expectations about meaning. Imagine trying to identify common objects such as kitchen utensils as fast as possible, both when presented in a normal scene or a jumbled display. Answer: a top down model of perception would predict that people could recognize them faster in a normal kitchen scene than in a jumbled display due to context effects.
