Pavlovian psychology, also known as classical conditioning or respondent conditioning, is a type of learning where a neutral stimulus is repeatedly paired with a stimulus that naturally produces a response. Over time, the neutral stimulus alone will start to produce the same response. In psychology, there are a variety of synonyms that can be used to refer to this type of learning. These synonyms include associative learning, reflex conditioning, and conditioned response. Other related terms include operant conditioning, which involves learning through consequences, and observational learning, which involves learning through watching others. All of these types of learning play important roles in shaping behavior and understanding the way people learn and adapt to their environment.
