Document Summary
Pylyshyn (1973) proposed the spatial representation within imagery is an epiphenomenon (may accompany real mechanism but is not causally related, similar to idea of correlation vs. causation) Argued that the underlying representations in imagery are propositional (symbols, language), rather than depictive (similar to realistic pictures) Pylyshyn (2003) proposed another alternative explanation for mental scanning results in the tacit-knowledge explanation. Kosslyn"s results can be explained by using real-word knowledge unconsciously. Participants simulated every part of the imagery experience, including the phenomenon of taking longer to move one"s focus greater distances i. e. slowed down when mentally moving from point a to c, as compared to a and. B, when a and c judged to be farther apart. Finke and pinker (1982): judge whether arrow points to dots seen on previous screen. Longer rt for greater distance between arrow and dot (as if mentally traveling"/tracing from dot to arrow)
