Attention, monotropism and the diagnostic criteria for autism.

Murray et al. (2005) wrote a narrative review. They asked: Could narrow, sticky attention be the real core of autism?

They looked at every diagnostic symptom. Social gaps, routines, sensory quirks. They mapped each one back to monotropism — a mind that can light up only one or two spots at a time.

The team argued that restricted attention can explain the whole checklist. If a child’s spotlight is tiny, social cues get missed, rituals feel safe, and sensory input feels huge.

They urged clinicians to test attention allocation, not just social skill gaps.

Mundy (2023) picks up the same torch but moves it into the RDoC yard. He keeps attention central, yet swaps the old monotropism story for the RDoC Social Process dimension. Same star, new map.

Yoder et al. (1981) sounds like a rival at first. They blamed bilateral temporal-lobe damage for autism traits. Brain versus mind. But the papers can coexist: one gives a neural site, the other gives a cognitive process.

Demello et al. (1992) adds practical grit. They showed DSM-III-R over-calls autism. Dinah’s lens would make the fix easy: add attention-scope items, cut false positives.

Next time you run an ADOS, tack on a quick attention probe. Note if the child locks onto one toy and shuts out voices. If the pattern fits, write “monotropic attention” in your report and build treatment around expanding that spotlight. You may boost social gains faster than drilling eye contact alone.
