Autism in Women and Girls: A Look at Special Interests
Monday, March 24, 2025
Having one or more focused, intensive interests is considered a core characteristic of autism. But for many years, experts seemed to know less about the special interests of autistic girls than they did about the stereotypical interests of boys. Researchers hope that the growing body of knowledge about autism in women and girls will improve our ability to identify autism and better support people in finding success and satisfaction in their lives.
Why “Restrictive” May Not Be the Best Descriptor
The phrase “restrictive interests” appears in the diagnostic language in the Diagnostic and Statistical Manual of Mental Disorders, Text Revision (DSM 5-TR), but it doesn’t necessarily capture the experience of many autistic women and girls. Labels such as “obsession” and “fixation” also carry negative connotations. Words like “fascination” and “passion” may come closer to capturing the deep joy and intense focus these interests inspire.
Here’s what some autistic women and their advocates say: Special interests don’t feel restrictive at all. By contrast, special interests can feel expansive. They may actually integrate various aspects of people’s lives by connecting experiences at school, in extra-curricular activities, in social lives, and at work.
Special interests can give people benefits like the following:
- a coping mechanism or self-care strategy to regulate emotion
- a subject or a world to understand and organize when much of the neurotypical environment may feel arbitrary
- a way of connecting with others who share similar interests
- a source of profound accomplishment and enjoyment
For some people, special interests eventually become a field of professional expertise. In a 2020 UC Davis MIND Institute panel discussion on “Life on the Spectrum: Women Sharing Their Unique Experiences,” computational biologist Lisa Malins explained, “Our intense interests bring us so much joy, and they can even translate into a career…even interests that might not seem to be career-related on the surface. I had a strong interest in video games first, and that led me to a gaming community that introduced me to HTML, which ultimately led me to bioinformatics, which is the career I’m currently in” (Malins, 2022, 28:08).
Her colleagues have expressed envy that she began developing her coding skills in childhood. She says, “Honestly, I have my autism to thank for that. I’m sure my parents got annoyed with me talking their ears off about Nintendo games, but because they gave me that space, it allowed that domino effect to occur that led me to my career field. And I think, in general, passion creates more passion” (Malins, 2022, 28:45).
What Does Research Say About Special Interests of Autistic Women and Girls?
Studies show that the ways autistic individuals engage with their special interests are mostly the same, regardless of sex and gender. Eight main “modalities” have been identified:
- speaking or thinking primarily about the area of interest
- creating
- seeking information
- memorizing
- collecting
- attaching
- seeking sensation
- self-soothing (Brown et al., 2024)
Quantity and Quality of Special Interests
As to the number of special interests, a 2022 literature review found that girls tend to have fewer or “less pronounced” special interests than boys. Among autistic girls and women, special interests tend to be less intense in childhood and more intense during the teen years (Bourson & Prevost, 2022).
Researchers have described the special interests of autistic women and girls as more socially acceptable than some of the subjects that may interest autistic boys (Simcoe et al., 2022). Special interests in horses and celebrities, for example, align closely with the interests of many neurotypical girls, so they may be less likely to draw attention from teachers, parents, or evaluators.
Some researchers have suggested that choosing areas of interest that are considered gender-appropriate or socially acceptable may be “interlaced with camouflage and imitating behaviour” (Simcoe et al., 2022).
Clinical developmental psychologist Marie Hooper, PhD, a late-diagnosed autistic and ADHD clinician, explained the risk of misdiagnosis linked to special interests in a 2024 webinar for Autism Ontario titled “Her Spectrum: Navigating the Unique Experiences & Needs of Autistic Girls & Women.”
“That’s why these girls are being missed,” Hooper said, “because their special interests are socially acceptable. If you say, ‘My daughter reads four chapter books a day,’ great! She’s a great reader! She’s going to do so well” (Hooper, 2024, 27:39).
Hooper said it can be more informative to look at how someone interacts with their special interest, as well as the degree of interest a person shows. An autistic girl might collect Barbies or My Little Pony figures, arranging them in a certain way, or dressing and re-dressing them, but without using them in imaginative play. “We have a lot of collecting and not so much engaging in play,” she notes (Hooper, 2024, 20:44).
As an example of intensity, Hooper described a student with a special interest in Taylor Swift, saying she was “a Swiftie through and through.”
“She has learned speeches that Taylor has given. She has learned how she speaks to people,” Hooper said. “Even when her mom says, at the end of the day, ‘Okay, it’s Taylor time!’…she will go back to studying videos of Taylor. She really wants to mimic her” (Hooper, 2024, 22:17).
Areas of Special Interest
In a recent study involving 1,992 autistic children and teens, researchers used the Special Interests Survey to explore differences in special interests between autistic boys and girls. More girls than boys in that study had special interests in these areas:
- animals
- art
- crafts
- music
- reading
- writing
Across sexes and genders, the most common areas of special interest were these:
- TV and movies
- attachment to certain objects
- music
These categories are broad; more research is needed to understand whether there are sex and gender differences in the types of music or characters that interest different groups of people.
In this study, parents characterized certain areas of special interest as “unusual” for both boys and girls:
- facts about things
- attachment to certain items
- schedules
- numbers
Parents also rated an interest in psychology in the top five most “unusual” among girls.
Why Should We Keep Studying the Special Interests of Autistic Girls and Women?
Understanding the nature of special interests is important for several reasons.
- When families, clinicians, and educators recognize intense special interests, they may be able to identify autism sooner and with greater accuracy.
- Special interests can point to strengths, skills, and coping strategies.
- Special interests can be leveraged to raise engagement in academic, social, and therapeutic pursuits.
- Sharing in and supporting special interests can improve family and social connections.
Key Message
Special interests are topics autistic girls and women study and explore with great passion. While having one or more intense special interest is included in the diagnostic criteria for autism, special interests may be seen as positive rather than negative from the perspective of an autistic individual.
On one hand, special interests foster joy and a sense of achievement. They can also spark social interactions and help people recover from stressful situations. On the other hand, because of their intensity, special interests may conflict with time constraints and social norms in some situations.
The special interests of autistic girls are often seen as more socially acceptable than the stereotyped interests associated with autistic boys, which may lead to missed autism diagnoses. Research into the characteristics of autism in girls and women is ongoing. The more we learn about special interests, the better we can become at identifying autism and building responsive support systems for autistic girls and women.
