shared some of the opinions of Chicago's professors. Egon Brunswik represents a more recent, but Continental, version. The functionalists retained an emphasis on conscious experience. Behaviourists also rejected the method of introspection but criticized functionalism because it was not based on controlled experiments and its theories provided little predictive ability. B.F. Skinner was a developer of behaviourism. He did not think that considering how the mind affects behaviour was worthwhile, for he considered behaviour simply as a learned response to an external stimulus. Yet, such behaviourist concepts tend to deny the human capacity for random, unpredictable, sentient decision-making, further blocking the functionalist concept that human behaviour is an active process driven by the individual. Perhaps, a combination of both the functionalist and behaviourist perspectives provides scientists with the most empirical value, but, even so, it remains philosophically (and physiologically) difficult to integrate the two concepts without raising further questions about human behaviour. For instance, consider the interrelationship between three elements: the human environment, the human autonomic nervous system (our fight or flight muscle responses), and the human somatic nervous system (our voluntary muscle control). The behaviourist perspective explains a mixture of both types of muscle behaviour, whereas the functionalist perspective resides mostly in the somatic nervous system. It can be argued that all behavioural origins begin within the nervous system, prompting all scientists of human behaviour to possess basic physiological understandings, something very well understood by the functionalist founder William James. The main problems with structuralism were the elements and their attributes, their modes of composition, structural characteristics, and the role of attention. Because of these problems, many psychologists began to shift their attention from mental states to mental processes. This change of thought was preceded by a change in the whole conception of what psychology is. Three parts ushered functional psychology into the modern-day psychology. Utilizing the Darwinian ideology, the mind was considered to perform a diverse biological function on its own and can evolve and adapt to varying circumstances. Secondly, the physiological functioning of the organism results in the development of the consciousness. Lastly, the promise of the impact of functional psychology to the improvement of education, mental hygiene and abnormal states Notable people James Angell James Angell was a proponent of the struggle for the emergence of functional psychology. He argued that mental elements identified by the structuralist were temporary and only existed at the moment of
