I know a lot of us listened to Loveline back in the day and heard this. That is, a girl with a high pitched voice would call in with some sex complaint and Dr. Drew would end up asking her if she’d been molested as a child. She’d end up saying yes, and he’d inform us that often girls who have been molested tend to regress back to that age (i.e., if you were molested as a five year old, you talk like you’re five).
It’s alluded to in this IMHO thread, about girls talking in baby voices. I was wondering if there was any hard evidence for this phenomenon.
