The term monotropic describes single attention and single channels for accessing and processing information (mono: single; tropism: direction/channel). NT developing individuals, although able to be single-minded at times, can respond to another interest or situation and shift their attention whether interested or not. This means they can use polytropic attention, which necessitates dividing their attention between a number of differing concerns simultaneously (poly: many) and accommodating many channels of information at any one time. Polytropism in typical individuals is argued to be their default learning style. This concept will be explored in more detail in this chapter.

I know that for many of us, shifting attention from an aspect of interest to one that we are not interested or invested in is very difficult. However, in AS this is often the reason we prefer sameness and routine, and why we may even appear to have one sense that dominates another. I suggest we use single attention connecting with and processing information one step at a time, which is the monotropic disposition, as our default setting. Therefore, attention and the interest system will work hand in hand to create an attention, interest, sensory-motor loop leading to a cognitive style.

Monotropism, or having the ability to home in on one aspect of communication or on one interest at one time, can happen to NT and AS individuals. However, rigid monotropism often occurs in an AS individual’s world, and we are said to have ‘tunnel vision’ (Attwood 2007) or, as parents often say, ‘my child seems only to be interested in his or her interests’. Monotropism will mean, for most of us, difficulties coping with change because we are single-minded. For many, this is demonstrated in our difficulties with change in routine, expectation, instruction, daily schedule, movement of attention or incorporating another set of demands into the present scenario. For example, coping with change can involve listening and then being required to participate in decision making without due time to process information; thus, being forced to move from one channel to another (Kluth and Chandler-Olcott 2008).

For many of us the discomfort at encountering change is one consequence of being attention-tunnelled or monotropic (e.g. Bogdashina 2006; Greenaway and Plaisted 2005; Murray et al. 2005).
