Does Behaviour Really come “Out of the Blue?”

Looking beyond “No apparent reason”.

Does Behaviour Really come “Out of the Blue?”

This article is based on my experiences working with Autistic children who also communicate in ways we find challenging. We do our best to find patterns, clues and reasons for episodes of challenging behaviour. When a behaviour if displayed with no noticeable trigger there are a number of reasons that may be behind this. With our students who do not communicate verbally it is often a case of us forming a hypothesis as to the reason whilst we collect further information about a range of factors that affect that student. I am going to outline three possible drivers that may lead to a behaviour being displayed with no clear trigger. Often challenging behaviour may be due to a mix of setting events and immediate triggers. They may also stem from a combination of internal and external antecedents. The behaviours displayed by our student’s both positive and those that are a challenge will often be triggered by the interactions between:

  • How they feel at that moment.
  • What has happened before.
  • What is happening around them at that time.

Setting events

We could think of these as “slow triggers”. They are underlying causes of anxiety or stress that precede the incident occurring. In PROACT training we call these “setting events”. These may precede the incident by a considerable length of time. In some cases this can be many years and be linked to dates of traumatic events, death of a parent etc or even expectation of repeated positive event e.g. “last year we visited Disneyland on this date why not this year?”. Changes in routine can also be setting events. If the routine is “work, snack, garden” then this changes to “work, snack, wait, garden.” The wait may be the setting event to an incident that occurs in the garden. With our students these changes may be very subtle.

Associative Memory

Many of our students will have a very strong factual memory that allows them to associate an exact memory of the sensations of an experience with a current sensory stimuli. The emotional reaction to these events may be positive, or may cause the child distress. This means a trigger to an action of concern may not be discernible to the member of staff supporting. This emotional reaction to sensations can lead to self-regulation difficulties for our students as they do not have the language skills available to rationalise their response[1]. They cannot filter the possible “threat” as a neuro-typical student might; triggering a fight, flight, or freeze response. This linked with emotional trauma (as outlined below) can lead to immediate panic response when common stimuli occur again. This can be a smell, sight, sound, and colour, item of clothing, environment, situation or date.

Emotional Trauma

Many of the students we work with have undergone emotional trauma of some sort, whether it be sustained exposure to aversive stimuli, negative experience of school, physical assault or even witnessing traumatic events. Post-traumatic stress occurs when there is severe negative influence on the nervous system. This can be one incident or long term exposure to distressing sensory stimuli. Many of our students are unable to control their immediate environment and this can lead to them being unable to feel safe. This constant feeling of panic can have long term impact on the nervous system.[2] This in turn may lead to the child being emotionally reactive and defensive to seemingly non-aversive situations. In training we talk about being the child’s emotional brakes. We can control our reactions and must be compassionate to the challenges our students face.

Internal Antecedent

The prevalence of triggers to challenging behaviour will vary according to each individual. External antecedents are the things happening around the student. These are often easier to identify because we can feel, hear, smell or see these. Although it is worth acknowledging that the senses we primarily use – sight and hearing will differ from our students whose perception of the environment differs. For example smells and touch may be more important to a student than auditory input.

It is only through the student expressing discomfort in some way or our interpretation of changes to their presentation that we will be able to gain a clue as to the cause. The better we know the student the more effective we will be on picking up these changes. We can also use a student’s historic behaviour data and medical history to determine the likelihood of internal antecedents existing. For example if they have a history of hayfever or constipation then we can begin to identify possible issues they are facing. As headaches and other pain are so difficult to identify think medical is a good first thought.

The more we know about the student and what has happened earlier the better picture we can build as to their current situation. This is where communication books are useful. If we know the student ate well at breakfast hunger is unlikely to be the cause, if they woke up really early or went to bed late then tiredness is a likely cause and we can adapt our approach accordingly.First Resort strategies for challenging behaviour PBS autism.png

Another type of internal antecedent may be within the student’s cognitive or mental environment,[3] their thoughts, self-esteem, fears and desires. Many of our students have rigid internal rules that are often a way of them controlling the environment and creating reliability and consistency in their lives. Examples I have come across are “you shouldn’t wear glasses”, “The windows should always be closed”. “That box goes on that shelf”. In these situation social stories and explanations may be useful. The following is a very simple list of strategies to work through if you are unsure.

  • Think medical!
  • Active listening
  • Lower demands
  • Offer a drink
  • Offer Food (Low blood sugar)
  • Prompt for toilet
  • Social story or explain minor changes.
