Autism is a natural part of human diversity. Autistic people tend to communicate and experience the world in a different way to non-autistic people. Historically, autism has been considered a ‘disorder’ seen in terms of deficits in social interaction and communication.
However, this has been challenged by many autistic people and researchers who have argued for a neuro-affirmative approach that recognises autism as a different neurological style that is marginalised and stigmatised within a predominately non-autistic world (Leadbitter et al., 2021; Walker, 2021).
From a neuro-affirmative approach, autistic researchers have argued that the way autistic people experience the world is characterised by monotropism (Lawson, 2011; Murray, 2021). The theory of monotropism argues that autistic brains are pulled more strongly to a narrower attentional focus compared to non-autistic people.
This can mean that autistic people can have more intense experiences, miss things outside of their current area of attention and find it hard to shift their attention from one thing from another. Non-autistic people generally have polytropic brains where they can spread their attention amongst multiple things in a less intense way.
The theory of monotropism validates the experience of autistic people without pathologizing their differences.
Strong passionate interests
Autistic people tend to have strong passions and their interests pull them in very strongly over time. All humans have things they are passionate about but what is generally different for autistic people is the intensity of their interests. It is important not to have stereotypical assumptions about what autistic people may be interested in.
Autistic inertia
Autistic inertia describes the tendency of autistic brains to resist changing states, stopping, starting or changing direction. This can make starting new tasks, being interrupted and changing plans challenging, however can also be associated with hyperfocus – the ability to intensely focus for long periods of time.
Sensory differences
Everyone has 8 sensory systems.
The commonly known – sight, hearing, smell, touch and taste – give information outside our bodies.
However, there are also 3 internal sensing systems:
- vestibular (co-ordinating movement with balance)
- proprioception (awareness of movement of the body)
- interoception (awareness of our internal state including emotions, temperature, pain hunger and thirst)
Every autistic person is different however, many are hypersensitive to external senses and hyposensitive to internal senses. It is much easier for autistic people to process one channel at a time and sensory over load can lead to exhaustion, meltdown or shutdown.
Stimming
Many autistic people will engage in stimming (or self-stimulatory behaviour) and this can be repetitive movements and/or sounds such as hand flapping, rocking or twirling. Stimming can be for enjoyment, to express happiness, or to increase or reduce sensory input (Charlton et al., 2021). Acceptance of stimming can enable autistic people to communicate and support sensory and emotional regulation.
Autistic people argue that its damaging to discourage stimming and leads to them being less tuned into their bodies and needs. Interventions aimed at reducing stimming – such as applied behaviour analysis (ABA) – have been associated with long term negative mental health outcomes such as increased post traumatic stress symptoms (Kupferstein, 2018; Anderson, 2022).
Interventions to support autistic people whose stimming may cause harm to themselves or others need to be person-centred, trauma-informed and neuro-affirmative.
Social differences
Autistic researchers have argued that social differences in autistic communication are linked to sensory differences and monotropism (Murray, 2018). The social norms of non-autistic communication include eye contact, small talk and indirect communication, for example, not saying directly what you mean. Being unable to process multiple channels of sensory input at one time can make processing the combination of speech, body language and eye contact involved in non-autistic communication very challenging.
Some autistic people without a learning disability may not use speech some or all of the time and will benefit from alternative communication methods.
These differences can lead to the perception that autistic people struggle with social communication. However, research suggests that non-autistic people struggle to understand the communication of autistic people (Sheppard, 2015; Edley et al., 2016). This has led to the theory of double empathy – that generally autistic people communicate most effectively with other autistic people, and non-autistic people communicate most effectively with other non-autistic people (Milton, 2012).
However, when autistic people communicate with non-autistic people they experience communication breakdown due to their different ways of experiencing the world.
Masking
Masking is when autistic people will consciously or unconsciously hide autistic characteristics or behaviours in order to fit in with a non-autistic world.
This may include: mimicking the behaviour of non-autistic people, hiding stimming or autistic passions, or developing complex social scripts in order to manage non-autistic communication.
Masking can be physically and mentally exhausting and research has suggested that masking has a negative impact on mental health (Cook et al., 2021) and can lead to an increase in suicidal behaviours (Cassidy et al., 2020).
High masking also increases the likelihood of later diagnosis.
Autistic burnout
The cumulative impact of masking, sensory overload and living in a world that is not adapted for autistic people can lead to autistic burnout (Raymaker et al., 2020).
As one autistic person in Raymaker and colleagues’ (2020:p137) research said: ‘‘Autistic burnout is a state of physical and mental fatigue, heightened stress, and diminished capacity to manage life skills, sensory input, and/or social interactions, which comes from years of being severely overtaxed by the strain of trying to live up to demands that are out of sync with our needs.’’
Many autistic people reported experiencing gaslighting or dismissal when they discussed their experiences of autistic burnout and reported that this exacerbates the negative impacts and led to feelings of social isolation (Raymaker et al., 2020).
Autistic people said that autistic burnout recovery is supported through:
- acceptance
- learning how to recognise the signs of autistic burnout
- reduced external pressures and sensory rest
- learning how to set healthy boundaries
- inclusive adjustments being made to support or work
- unmasking and being able to authentically live their lives as an autistic person (Mantzalas et al., 2022).
Autistic people tell us that recovery from autistic burnout is often a prolonged and staged process.
PDA
PDA is commonly referred to as Pathological Demand Avoidance but a more neuro-affirmative reframing is ‘pervasive drive for autonomy’ (PDA Society, 2022). People with a PDA profile generally experience a fight, flight or freeze response as a result of demands (which are anything they perceive as a threat to their autonomy).
This could include self care tasks such as bathing or doing laundry, social expectations or being told what to do by others, for instance at work, home or school.
People with a PDA profile may want to do something but not be able to because their internal response to a perceived loss of autonomy is so intense. They may respond by avoiding demands and expectations, having intense emotional responses or using strategies to remain in control of a situation.
People with a PDA profile are also often innovative and independent thinkers and highly empathetic and intuitive.
Co-occurring experiences
Autistic people often experience other forms of neurodivergence such as:
- ADHD - (Attention Deficit Hyperactivity Disorder)
- dyslexia
- dyspraxia
- epilepsy
- OCD (Obsessive Compulsive Disorder).
Many autistic people also experience:
- gastrointestinal issues
- sleep issues
- Ehlers-Danlos syndrome
- other forms of hypermobility
