A strength of the behaviourist perspective is that it’s scientific as most the research done is in a lab setting with high controls. Watson and Raynor conducted an experiment in a controlled environment and tested if little Albert was scared of the rat beforehand. This is a strength as it means objective data is collected and a cause effect relationship can be identified. However, as little Albert couldn’t speak we couldn’t get any insight and so may have had to interpret how he felt which is subjective.
