<unk>  is often described as "tunnel vision".Monotropism is a cognitive strategy posited to be the central underlying feature of autism. A monotropic mind is one that focuses its attention on a small number of interests at any time, tending to miss things outside of this attention tunnel. The theory of<unk>  was developed by Dinah Murray, Wenn Lawson and Mike Lesser starting in the 1990s, and published about in the journal Autism in 2005. Wenn Lawson's further work on the theory formed the basis of his PhD, Single Attention and Associated Cognition in Autism, and book The Passionate Mind (Lawson, 2011). A tendency to focus attention tightly has a number of psychological implications. While<unk>  tends to cause people to miss things outside their attention tunnel, within it their focused attention can lend itself to intense experiences, deep thinking and flow states. However, this hyperfocus makes it harder to redirect attention, including starting and stopping tasks, leading to what is often described as executive dysfunction in autism, and stereotypies or perseveration where a person's attention is repeatedly pulled back to the same thing.
