Abstract
Physiological psychology has its conceptual roots in stimulus‐response behaviourism. The resurgence of cognitive concepts in mainstream psychology has led to a separation between the two, largely due to the failure of most cognitive theories to specify how their explanatory processes could be realised in the nervous system. Connectionism looks as if it may be able to bridge this gap. The problem is that connectionism takes a radically different view of the brain from that adopted in traditional physiological psychology. This paper looks at some of the implications of connectionism for how physiological psychology should develop. It also looks at the implications of the findings of physiological psychology for connectionism.
