The functional control exerted by a stimulus enables us to distinguish between sensing and certain other activities suggested by such terms as "seeing," "perceiving," or "knowing." "Sensing" may be taken to refer to the mere reception of stimuli. "Seeing" is the "interpretive" behavior which a stimulus controls. The term "seeing" characterizes a special relation between behavior and stimuli. It is different from "sensing" just as responding is different from being stimulated. Our "perception" of the world - our "knowledge" of it - is our behavior with respect to the world. It is not to be confused with the world itself or with other behavior with respect to the world or with the behavior of others with respect to the world.【原書140頁】
ある刺激による機能的なコントロールは、“感じる(sensing)"ことと、“見る(seeing)"とか“知覚する(perceiving)"とか“知る(knowing)"という言葉で示唆される行動との区別を可能にする。“感じる”というのは、単に刺激を受け取ることを述べている。“見る”というのは、刺激がコントロールしている“解釈された”行動である。"見る”という言葉は、行動と刺激との間の特別な関係を特徴づける。“見る”ことが“感じる”ことと異なるのは、反応することが刺激されることと異なるのと同じである。われわれの“知覚”や“知識”は、外界に対する行動の一側面である。したがってわれわれの行動を、世界そのものと、あるいは世界に対するその他の行動と、あるいは世界に対する他者の行動と、混同すべきではないのである。【翻訳書163〜164頁】

A man may see or hear "stimuli which are not present" on the pattern of the conditioned reflex: he may see X, not only when X is present, but when any stimulus which has frequently accompanied X is present. The dinner bell not only makes our mouth water, it makes us see food.

Skinner briefly describes his own experiences of auditory, musical imagery, and in his influential Science and Human Behavior (Skinner, 1953), he discusses, in a speculative way, the causes of what he calls “conditioned seeing” and “operant seeing” (1953 ch. 17), which are clearly intended as non-mentalistic ways of referring to the experiencing of imagery, that will not violate Behaviorist principles. In his About Behaviorism (1974), Skinner reiterates essentially restates his earlier position, but allows himself to speak more freely of “visualizing,” “imaging,” and “seeing in the absence of the thing seen.”
