This is the Stanford Encyclopedia of Philosophy entry on the contents of perception.

Almost all contemporary philosophers on the subject agree that emotions play an indispensable role in the justification (as opposed to the mere causation) of other mental states and actions. However, how this role is to be understood is still an open question. At the core of the debate is the phenomenon of conflict without contradiction: why is it that an emotion need not be revised in the light of better judgment and knowledge? Conflict without contradiction has been explained either by (...) difference in content between emotion and judgment, or by a difference in the respective attitude towards content. I argue that conflict without contradiction is due to both differences, where difference in content is prior to difference in attitude. (shrink)

Representationalism is the position that the phenomenal character of an experience is either identical with, or supervenes on, the content of that experience. Many representationalists hold that the relevant content of experience is nonconceptual. I propose a counterexample to this form of representationalism that arises from the phenomenon of Gestalt switching, which occurs when viewing ambiguous figures. First, I argue that one does not need to appeal to the conceptual content of experience or to judgements to account for Gestalt switching. (...) I then argue that experiences of certain ambiguous figures are problematic because they have different phenomenal characters but that no difference in the nonconceptual content of these experiences can be identified. I consider three solutions to this problem that have been proposed by both philosophers and psychologists and conclude that none can account for all the ambiguous figures that pose the problem. I conclude that the onus is on representationalists to specify the relevant difference in content or to abandon their position. (shrink)
