Pathological demand avoidance (PDA) is now considered to be part of the autism spectrum. Individuals with PDA share difficulties with others on the autism spectrum in social aspects of interaction, communication and imagination.Cognitive levels of learning however, the central difficulty for people with PDA is the way they are driven to avoid demands and expectations. This is because they have an anxiety based need to be in control.Cognitive levels of learning people with PDA seem to have a better social understanding and communication skills than others on the spectrum and are able to use this to their advantage.Cognitive levels of learning

As the term spectrum suggests, individuals are affected in different ways and to varying degrees. Often in cases of PDA there will have been a passive early history, but this is not always the case.Cognitive levels of learning it is believed that there may be neurological involvement in some cases, with a higher than usual incidence of clumsiness and other soft neurological signs.Cognitive levels of learning

Other children and young people on the autism spectrum can display one or more of the features of PDA. When many occur together it is helpful to use the PDA diagnosis, as the strategies and interventions that help a person with PDA differ to those that benefit others on the autism spectrum.Cognitive levels of learning people with PDA can be controlling and dominating, especially when they feel anxious. However, they can be enigmatic and charming when they feel secure and in control.Cognitive levels of learning many parents describe their child with PDA as a ‘jekyll and hyde’ character. It is important to acknowledge that these children have a hidden disability.Cognitive levels of learning many parents of children with PDA feel that they have been wrongly accused of poor parenting through lack of understanding about the condition.Cognitive levels of learning these parents will need a lot of support, as their children can often present severe behavioral challenges.

A diagnosis is the formal identification of PDA, usually by a professional.Cognitive levels of learning recognition of PDA as a condition is fairly recent, and the apparent social abilities of many children with PDA mask their problems. Many children are not diagnosed until they are older and may already have a diagnosis of autism or asperger syndrome.Cognitive levels of learning sometimes parents may feel that something about this diagnosis doesn’t quite fit. It is usually the surface sociability and the often vivid imaginations of children with PDA which confuse professionals regarding the diagnosis.Cognitive levels of learning

The main characteristic of PDA is a high level of anxiety when demands are placed on that person. Demand avoidance can be seen in the development of many children, including others on the autism spectrum.Cognitive levels of learning it is the extent and extreme nature of this avoidance that causes such difficulties, which is why it has been described as ‘pathological’. Resists and avoids the ordinary demands of life

This is the feature of behavior that gives the name to the syndrome. Children can seem under an extraordinary degree of pressure from everyday expectations and they may attempt to avoid these to a remarkable extent.Cognitive levels of learning demands might include a suggestion that it’s time to get up, go out of the house or join a family activity. At times any suggestion made by another person can be perceived as a demand.Cognitive levels of learning

Underpinning this avoidance is an anxiety about conforming to social demands and of not being in control of the situation. Of course, children with autism may also react to social demands by avoiding but they tend to do this in ways that aren’t very social in nature by ignoring, withdrawing or walking away.Cognitive levels of learning A key feature of PDA is that the child has sufficient social understanding to use a level of social manipulation in their attempts and will often adapt strategies to the person making the demand.Cognitive levels of learning

Parents very often use the term ‘manipulative’ to describe this aspect of their child’s behavior and will comment on how it seems to be their greatest skill, often saying “if only they would put half the effort in to doing what it was I wanted as they do to getting out of it.” those with PDA may also use straightforward refusal or outbursts of explosive behavior, including aggression.Cognitive levels of learning this is a form of panic on their part and is usually displayed when other strategies haven’t worked or when their anxiety is too high that they will ‘explode’ or have a ‘meltdown’.Cognitive levels of learning this can take the form of shouting, screaming, throwing things and physically lashing out, often in a very sudden and dramatic way. Not all individuals with PDA have explosive outbursts, but it seems to affect a significant number.Cognitive levels of learning

A feature of this poor judgement is an ambiguity in their mood and responses like hugging becomes pinching or a child may embrace their parent while saying something like “I hate you”.Cognitive levels of learning this demonstrates both their own confusion and the fact that their behavior can be confusing to others. Edward’s parents talked about how he treats everyone the same:

cognitive levels of learning

He’s got no sense of authority and doesn’t recognize ‘a pecking order’. He generally relates well to adults and responds better if you adopt an adult style of speech to him.Cognitive levels of learning he talks to other children as though he was an adult or in a teacher role, and for example, will try to stop children going out to play if it’s raining.Cognitive levels of learning he treats his niece in the same way as his parents do, as though he was just another adult.

People with PDA switch from one mood to another very suddenly in a way that can be described as “like switching a light on and off”.Cognitive levels of learning the emotions shown may seem very dramatic and over the top or, according to some parents, like an act. Difficulty with regulating emotions is common in all children on the autism spectrum, but early studies found it especially prevalent in PDA.Cognitive levels of learning mood swings and impulsivity, were also shown to persist beyond childhood in the majority of those with PDA. This switching of mood often seems to be driven by the child’s need to control and they can:

Rapid and often unexpected changes of moods, together with their overall variability of behavior, can make children with PDA very unpredictable.Cognitive levels of learning comfortable in role play and pretend, sometimes to an extreme extent. Children with PDA are often highly interested in role play and pretend.Cognitive levels of learning this was recognized early on as being different from other children on the autism spectrum. Children with PDA often mimic and take on the roles of others, extending and taking on their style, not simply repeating and re-enacting what they may have heard or seen in a repetitive or echoed way.Cognitive levels of learning about a third of children in early studies were reported to confuse reality and pretense at times.

Individuals with PDA, especially children, will often incorporate role play or pretend in the strategies that they use to avoid demands or exercise control.Cognitive levels of learning when they become involved in play scenarios with other people, they will nearly always try to direct and this can cause real conflict, especially with other children.Cognitive levels of learning language delay, often with good degree of catch-up

The large majority of children with PDA are delayed in some aspect of their early speech and language development, although this may be dependent on their intellectual ability.Cognitive levels of learning this initial delay seems to be part of their overall passivity and there is often a sudden degree of catch-up. Individuals with PDA have more fluent use of eye contact (other than when avoiding demands) and conversational timing than others on the autism spectrum.Cognitive levels of learning generally, they tend to have less difficulty understanding non-verbal communication. However, some do have difficulties such as taking things literally and understanding sarcasm and teasing.Cognitive levels of learning

While the majority of people with PDA become fluent in using expressive language, some have a problem with their understanding. They can have difficulty with processing what they hear and need additional time to do this.Cognitive levels of learning this can lead to misunderstandings and disruption to the communication process which can contribute to their behavior. Obsessive behavior, often focused on people

cognitive levels of learning

Strong fascinations and special interests pursued to an ‘obsessive’ degree are very characteristic of children across the spectrum. Due to that, this characteristic does not distinguish a child with PDA from others on the autism spectrum.Cognitive levels of learning however, elizabeth newson noted that the demand avoidance behavior itself usually has an’‘obsessive feel’. Children with PDA may have a strong fascination with pretend characters and scenarios.Cognitive levels of learning the subjects of fixations for people with PDA can also revolve around specific individuals they interact with. This can result in blame, victimization and harassment that cause problems with peer relationships.Cognitive levels of learning sensory differences

A large proportion of people with PDA can have real problems controlling their temper. As children, this can take the form of prolonged meltdowns as well as less dramatic avoidance strategies like distraction, giving excuses etc.Cognitive levels of learning it is essential to see this as extreme anxiety or ‘panic attacks’ and to treat them as such. Try using reassurance, calming strategies and de-escalation techniques.Cognitive levels of learning

Sometimes a child with PDA can appear very anxious at home but remain relatively passive at school. This is a learned coping strategy that can make parents feel very isolated and inadequate.Cognitive levels of learning in other cases, outbursts are far worse at school, where demands may be much greater, and this can lead to multiple exclusions at an early age.Cognitive levels of learning for some children, this anxiety can develop to such an extent that they refuse to go to school. Other conditions and areas of overlap

PDA is often diagnosed alongside other conditions, such as ADHD, dyslexia, and dyspraxia.Cognitive levels of learning this may be a result of overlapping conditions but can also be due to confusion over the diagnosis. Before being diagnosed with PDA, some people will have already been diagnosed with autism, ASD or atypical autism.Cognitive levels of learning PDA can also be present alongside more generalized learning difficulties and, at times, the apparent verbal fluency of people with PDA can mask genuine difficulties in understanding.Cognitive levels of learning

Underpinning this approach is the understanding that a person with PDA does not make a deliberate choice to not comply and they cannot overcome their need to be in control.Cognitive levels of learning however, with the right support, they may begin to make a series of achievements as trust and confidence builds. The PDA society have very useful information for families on their website.Cognitive levels of learning education – intervention and approaches

There is currently no cure for a person with PDA but our knowledge about appropriate interventions and educational approaches is growing.Cognitive levels of learning one of the most important reasons for distinguishing PDA from other conditions is to ensure that the child receives the correct educational approach.Cognitive levels of learning best practice differs fundamentally between children with PDA and children with autism. The use of structured teaching methods, which are so successful for people with autism and asperger syndrome, are usually much less helpful for people with PDA and need considerable adaptation.Cognitive levels of learning people with PDA do not respond to structure and routine and prefer to be taught in a more indirect way using a style of negotiation that allows them to feel in control.Cognitive levels of learning what causes PDA and who are affected?

The exact cause of PDA is still being investigated. However, as with autism and asperger syndrome, research suggests that a combination of factors, genetic and environmental may account for changes in brain development.Cognitive levels of learning unlike autism and asperger syndrome, PDA seems to affect boys and girls equally. There are no prevalence rates for PDA as yet. It seems likely that the genetic factors are similar to those in autism and that about six percent of children with PDA are known to have a sibling with an autism spectrum disorder.Cognitive levels of learning as more diagnoses of PDA are made, prevalence figures will become more apparent. PDA affects people from all backgrounds and nationalities. History and recent research

cognitive levels of learning

Pathological demand avoidance (PDA) was a term first used by professor elizabeth newson in the 1980s, to describe the profile of a group of children she had seen for assessment at the child development research unit in nottingham.Cognitive levels of learning her initial writings were informally published as a part of conference proceedings, until the first journal article appeared in the archives of diseases in childhood in 2003.Cognitive levels of learning
