It's possible you might be thinking of something else, like:
* The Turing Test: This is a test of a machine's ability to exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human. It was proposed by Alan Turing in his 1950 paper, "Computing Machinery and Intelligence."
* The Chinese Room Argument: This is a thought experiment proposed by philosopher John Searle, which questions whether a machine that passes the Turing test truly understands language or just manipulates symbols.
If you could provide more context or details about the "Rochester test," I might be able to help you further.
