Explain why passivity phenomena are considered closely related to, but still distinct from, the alienation of thought seen in thought insertion, withdrawal, and broadcasting.

Both passivity phenomena and the alienation-of-thought experiences share the same underlying structure: something that should belong to the person — a thought, an action, a feeling — is instead experienced as originating from, or under the control of, an outside agency, and both are typically held with full delusional conviction. What differs is simply which domain of mental life is affected. Thought insertion, withdrawal, and broadcasting concern thoughts specifically. Passivity phenomena extend that same 'made' quality to actions and feelings instead. Because the underlying mechanism is so similar, the two families of experience are often grouped together conceptually and frequently occur in the same patient, but keeping them distinct in description and terminology preserves useful clinical detail about exactly which part of the person's mental life feels taken over.
