Who they are
Dinah Karen Crawshay Murray (1946–2021) was an autistic writer, educator, and researcher who spent three decades advocating for autistic people and contributing to autism studies. She is best known for developing monotropism theory alongside Wenn Lawson and Mike Lesser, a framework that has become central to how autistic people understand their own cognition and to how researchers explain autistic attention, social behaviour, and sensory experience.
Murray was described by colleagues as “a productive irritant,” a phrase that captures something of her role in the field: she persistently pushed autism research toward the autistic perspective, insisting that understanding autism required understanding how autistic attention actually works rather than cataloguing what autistic people cannot do.
Key contributions
Monotropism
Murray’s most significant contribution was developing monotropism theory, published as “Attention, monotropism and the diagnostic criteria for autism” in Autism (2005) with Mike Lesser and Wenn Lawson. The core proposition: autistic attention is distributed differently from neurotypical attention. Where neurotypical attention tends toward polytropism (distributed broadly across many channels), autistic attention is monotropic (concentrated intensely on fewer channels).
This single insight explains much of what clinical autism research tried to capture with separate constructs: the intense interests are monotropism in the interest domain; the social differences are monotropism in the attention domain (difficulty distributing attention across a room of people); the sensory patterns reflect different allocation of attentional resources across sensory channels; the insistence on sameness reflects resistance to being pulled out of a monotropic tunnel of focus.
Monotropism does not need a separate Theory of Mind module, a separate central coherence theory, or a separate sensory integration theory. It offers a single attentional framework that accounts for multiple features of autistic experience. See Autistic social experience for how monotropism explains social cognition.
Validation through the Monotropism Questionnaire
Murray’s theoretical work was posthumously validated by Garau et al. (2023), who developed the Monotropism Questionnaire (MQ), a 47-item self-report measure tested across 1,110 participants. The measure distinguishes autistic from non-autistic participants and, notably, finds the highest monotropism scores in people who identify as AuDHD. See AuDHD for the implications of this finding.
Autism as difference, not deficit
Throughout her career, Murray argued that autism is a different way of being in the world rather than a disordered version of neurotypicality. This was not a new claim, but Murray grounded it in a specific cognitive mechanism (monotropism) rather than relying on philosophical argument alone. The combination of empirical theory and personal experience gave her work authority in both academic and community contexts.
Critical assessment
Monotropism, as originally published, is a theoretical framework rather than a fully tested empirical model. The 2005 paper is conceptual; the empirical validation (through the MQ) came 18 years later, after Murray’s death. Some critics note that the theory is difficult to falsify, since monotropism can potentially explain any autistic feature if defined broadly enough.
The theory is stronger as an explanatory framework for social and attentional differences than for sensory processing specifically. Whether sensory hyper- and hyposensitivity can be fully explained by attentional allocation, or whether they require separate sensory-level mechanisms, remains an open question. The predictive processing framework (see Predictive processing and autism) offers a complementary account that addresses sensory mechanisms more directly.
Murray’s work has been taken up enthusiastically by the autistic community, which is both a strength (it centres autistic experience) and a caution (community adoption is not the same as empirical validation).
