Language and learning: the cognitive revolution at 60-odd

Around the middle of the last century, the prevailing psychological paradigm of behaviourism was challenged by what is now known as the cognitive revolution. Behaviourists viewed learning as changes in patterns of behaviour through reinforcement. By contrast, advocates of the cognitive approach argued that such behavioural changes were outward manifestations of computational operations on mental representations. Here we consider the current state of the cognitive revolution, focusing on the two most contentious issues in the debate: language and learning. The cognitive approach has proved to be extremely fruitful in both fields. Although contemporary learning theory has almost completely embraced the cognitive approach, the study of language has witnessed a clear empiricist trend to revert back to a kind of neo-behaviourism. Many contemporary authors contend that language is a means of communication that is learned solely through the observation of external events, and culturally transmitted to successive generations. Here, we argue that learning and language can only be properly understood from a cognitive perspective, where the mind is conceived of as a biologically underpinned computational system. As is the case in learning theory, there is abundant evidence showing that language is subserved by an autonomous cognitive system in the mind. We conclude that the cognitive revolution has fundamentally changed our understanding of the mind.
