The article by Professor John Dewey discusses the concept of the reflex arc in psychology, emphasizing its role as a unifying principle and working hypothesis. Dewey argues that the reflex arc, which represents both the unit of nerve structure and the type of nerve function, is a more comprehensive and organic unity compared to the traditional dualism between sensation and idea. He critiques the common interpretation of the reflex arc, which treats sensory stimulus and motor response as distinct entities, suggesting that these elements are actually functional divisions within a larger sensori-motor coordination. Dewey emphasizes that the reflex arc is not a simple sequence of events but a continuous process of coordination and mediation, where the motor response influences and determines the stimulus, and vice versa. He illustrates this with examples such as a child reaching for a candle and getting burned, showing how these experiences are not isolated events but part of a larger sensori-motor circuit. Dewey concludes that the reflex arc concept should be seen as a circuit rather than an arc, highlighting the importance of understanding the functional relationships between sensory and motor processes in psychological and biological contexts.The article by Professor John Dewey discusses the concept of the reflex arc in psychology, emphasizing its role as a unifying principle and working hypothesis.
