Not just socially but generally?
Mentally, socially, emotionally...in their hobbies, thoughts etc..
In AS, the brain's Executive Function virtually stops (or significantly slooows) developing at or around adolescence - the Executive Fuction is involved in developing the ability to plan and carry out complex actions, such as buying a home or car, putting together a retirement plan, building a business, etc., as well as: situations where responses are not well-learned or contain novel sequences of actions, and situations which require the overcoming of a strong habitual response or resisting temptation.
Which is to say, basically that the parts of the brain that gradually turn one from a kid into a grownup are somewhat stunted - not nonexistent, but ret*d in maturation. So it is not uncommon for those of us with AS to be very childlike in many respects - this probably contributes to classic Aspie traits like Blunt Honesty (not knowing when others don't want to hear the truth); Lack of Empathy (being so preoccupied with our own interests, we don't notice when others need our support and interaction); Meltowns ( being overwhelmed by to much incoming sensory stimuli or social interaction or responsibility). In fact, I suspect it goes hand-in-hand with our basic sensory processing problems.
But 'immature' in the sense of being impudent, or bratty? I wouldn't think we're any more predisposed to that sort of behavior than anyone else. I do think we may be
perceived that way by those who do not understand what's happening when we are being overwhelmed by our environment.

Also, sentence structure and word choices more childish, immature, slang etc...
Since Hans Asperger frequently referred to his young diagnosees as 'Little Professors' specifically because of their broad vocabularies and proficiency with language, I would expect that 'immature' verbal communication would be the exception among those with AS.
