Connectionism refers to E. L. Thorndike’s term for his theory of learning , based on the notion that learning is the formation of neural connections between stimuli and responses.
Moreover, Connectionism refers to a theoretical perspective that holds that thinking consists of activating connections in a network of interconnected nodes and of activation spreading in this network along paths determined by the strengths of the connections among those nodes. Connectionism is an approach to cognition emphasizing parallel processing of information through immense networks of interconnected nodes. Models developed in the Connectionist tradition are sometimes declared to share certain similarities with the way collections of neurons operate in the brain; hence, some connectionist models are referred to as neural networks.
