However, reflexes alone don't explain how animals survive and evolve. For example, dogs have a salivary reflex: they slobber because this helps them separate good food from bad. Reflexes are involuntary behaviours that are passed on down the species because they have " survival value". Pavlov is particularly interested in animal behaviour called " reflexes". If this is true, then you would expect the rules of animal behaviour to apply to humans too. If, as Charles Darwin proposes, humans and animals have common ancestors, then humans are really a particular type of animal. He justifies this by appealing to the Theory of Evolution. Pavlov is interested in the human brain but did his research on dogs. However, Pavlov spends time justifying and evaluating his research and it is worth noting some of the points he raises. Students don't need to know everything Pavlov discussed in his lectures the study on dogs is what matters. However, it raises important methodological issues about drawing conclusions from animal research and the low ecological validity of artificial situations. It illustrates the usefulness of the observational method, especially controlled observations in artificial conditions.He also showed how the Learning Approach and the Biological Approach cross over. It shows how scientific research proceeds, because Pavlov brought physiology (the study of the body) together with psychology (the study of the mind).This research is significant for students in other ways: Perhaps without meaning to, he promoted the behaviourist school of Psychology, which regards all behaviour as conditioned responses. However, he was aware of the cross-over between biology and psychology and his lectures developed the status of Psychology as a scientific discipline, shedding new light on how the brain works by observing behaviour. Pavlov was interested in the workings of the human brain, but conducted tests on animal brains, notably dogs. This research is actually a series of lectures by the Nobel Prize-winning Russian scientist Ivan Pavlov.
