Defining the behavioral phenotype of Asperger syndrome.
Asperger syndrome carries a unique ‘active-but-odd’ social flavor that differs from the withdrawn style of classic autism and often co-occurs with ADHD and executive issues.
01Research in Context
What this study did
Ghaziuddin (2008) watched a small group of adults with Asperger syndrome during everyday social moments.
The team wrote down every social move and sorted each person into one of four social styles.
They did the same for adults with classic autism so they could compare the two labels.
What they found
Almost every adult with Asperger syndrome showed the ‘active-but-odd’ style. They walked up to people, talked a lot, but what they said was off-key.
Adults with classic autism mostly stayed quiet, avoided contact, and looked ‘aloof and passive.’
The two labels showed clear, different social pictures, not just mild versus severe autism.
How this fits with other research
Griffith et al. (2012) later saw the same ‘active-but-odd’ style in kids and teens with high-functioning ASD. They added that these kids also had more ADHD symptoms and lower well-being.
Paolizzi et al. (2025) found parents often miss the ‘active-but-odd’ style in girls. Parents rated their daughters as more social than clinicians did, showing the style can hide behind parent reports.
Ambery et al. (2006) looked at the same adults with Asperger syndrome but tested memory and flexible thinking instead of social style. They found real cognitive gaps that go hand-in-hand with the odd social vibe.
Why it matters
If you see a chatty client who keeps approaching peers but rubs them the wrong way, think ‘active-but-odd,’ not ‘socially motivated with mild autism.’ This profile calls for teaching subtle social rules, not just increasing eye contact. Also screen for ADHD and executive gaps—these often ride along with the style. Naming the pattern sharpens your treatment plan and helps parents understand why friendly overtures still fail.

03Original abstract
Asperger syndrome (AS) is characterized by social deficits and restricted interests in the absence of mental retardation and language delay. However, it is unclear to what extent the social deficits of AS differ from those of traditional autism. To address this issue, 58 subjects with AS were compared with 39 subjects with autism. Social deficits were classified according to Wing and Gould's method. Forty-six (79%) subjects with AS were rated as active but odd, while 32 (82%) with autism were described as aloof and passive, while a few subjects showed mixed features. Thus, despite the overlap between AS and autism, subjects with AS showed a distinct pattern of social impairment. Implications of these findings are discussed.
