What is the place of consciousness in psychology's history?

Consciousness has been a central topic in the history of psychology, particularly during the early 20th century with the rise of structuralism and functionalism. However, behaviorism and later cognitive psychology shifted the focus away from consciousness due to its subjective nature and lack of empirical measurement. Recently, there has been a resurgence of interest in studying consciousness through various approaches such as cognitive neuroscience and phenomenology.
