Visual world studies of conversational perspective taking: Similar findings, diverging interpretations

What we have proposed is that when a listener tries to understand what a speaker means, the process he goes through can limit memory access to information that is common ground between the speaker and his addressees. [...] ...the comprehension process must keep track of common ground, and its performance will be optimal if it limits its access to that common ground. Whether its design is actually optimal in this respect is a question that can only be answered empirically. (Clark & Carlson, 1981, p. 76-77)
