In the first experiment, we test the membership weights of a list of exemplars with respect to two concepts, e.g., {\\it Fruits} and {\\it Vegetables}, and their conjunction {\\it Fruits And Vegetables}. In the second experiment, we test the membership weights of the same list of exemplars with respect to the same two concepts, but negating the second, e.g., {\\it Fruits} and {\\it Not Vegetables}, and again their conjunction {\\it Fruits And Not Vegetables}.
