That's interesting. I tested on the autistic side with this question, which I'm inclined to agree with. Again only one anecdote though. I wonder how accurate this question actually is. I'd love to test it against my wife, but her English is not perfect, so I'm not sure whether or not she knows what that noun is. I wonder if you could replace that noun with any other generic noun that is more recognizable to non-native English speakers without affecting the identification mechanism, however it may work. If I have to define the noun for her, I wonder if it would affect the result.
