Behavioural learning theories, including classical conditioning, operant conditioning, and observational learning, focus on observable behavior as a measure of learning. The strengths of this theory lie in its basis on observable behavior, making it easy to collect and quantify data. It is also effective in everyday scenarios, as seen in schools that use rewards and punishment. However, criticisms include its one-dimensional approach, overlooking other forms of learning, and neglecting internal factors and individual emotions. Despite its limitations, behavioural learning theory remains widely used, especially in incentivizing desired behavior in the workplace.
