law of contrast

a principle of association stating that opposites are reminders of one another: encountering or thinking about one (e.g., a snow-covered field) tends to bring to mind the other (e.g., a sunny beach). Initially proposed as a distinct, essential concept in associationism, the law of contrast later came to be viewed as a special case of the law of contiguity.
