Final answer:
Behaviorism is a school of thought that focuses on studying overt behavior and de-emphasizing unobservable mental processes. It has three stages: behaviorism, logical behaviorism, and semantic behaviorism. These stages relate to radical behaviorism and methodological behaviorism.
Step-by-step explanation:
Behaviorism is a school of thought within psychology that focuses on studying overt behavior and de-emphasizing the importance of unobservable mental processes. There are three stages of Behaviorism: i) Behaviorism, which seeks to make psychology an objective science by studying behavior; ii) Logical behaviorism, which argues that mental states are equivalent to behavioral dispositions; and iii) Semantic behaviorism, which emphasizes the meaning of mental terms in relation to behavior.
This progression relates to the ideas of radical behaviorism and methodological behaviorism. Radical behaviorism, associated with B. F. Skinner, emphasizes the study of observable behavior and how it is shaped by environmental factors. Methodological behaviorism, associated with John Watson, focuses on studying behavior as the primary subject matter of psychology, without making claims about inner mental states.
