There is a very popular ABC (Antecedent – Behavior – Consequence) approach when the carer is supposed to find the trigger (Antecedent), define the Behavior and provide the Consequence for this (often called inappropriate) behaviour – ignore/ time out/ etc. In autism this approach does not always work. Sometimes the antecedent cannot be easily identified, because it can be either ‘present but invisible’, or ‘possible future’, or ‘past’ antecedent. Let me explain.

Present but invisible antecedent

Sometimes we cannot see/ hear/ feel certain stimuli as our senses are too ‘normal’. For example, the child may be disturbed by the sound of the microwave oven two rooms away. As the carer cannot hear it, any ‘challenging behavior’ displayed by the child would be interpreted as ‘out of the blue’.

Possible future antecedents

Not only certain stimuli but also any sudden unpredictable stimuli can be painful. The fear of the stimulus that ‘hurts’ is often the cause of challenging behaviors. The antecedents cannot be easily identified because they are ‘possible future antecedents’. Some autistic children may try to break things (for example, telephone or alarm clock) that can produce unpredictable painful sound. They do it as a protective reaction. For instance, Alex, a 9-year-old child with classic autism could not tolerate the sound of babies crying. Even when a baby was asleep he would try to attack (hit or kick) it. The trigger (antecedent) was ‘in the future’. It was easier for Alex to tolerate the cry, when he was prepared for it and could see the source of it. This explains his ‘challenging’ behaviour – to initiate and be in control of the painful sounds, make them predictable, instead of jumping out of his skin when the baby starts crying and he does not expect it.

Past antecedent

Sometimes any stimuli (not only sensory but also emotional ones) may bring memories of pain, or anger, or panic (happened in the past). As any memory brought to the surface (i.e. to consciousness) becomes very much ‘present’, the child may react the way he or she reacted in the past, when the bad experience happened. What can provoke anger, fear, anxiety, panic attack? Anything! From smell to emotionally colored intonations. For example, some smells can bring pleasurable memories, and other odors remind one of unhappy ones. Or take another trigger – an emotional aspect of the word. Some words have emotional coloring that can be negatively charged. In autism, the conventional interpretation often doesn’t matter. If something unpleasant happened when the child heard the word ‘sorry’, for example, he would connect this word with the experience. Any time the child hears ‘Sorry!’ he may react with rage – the experience repeats itself.

The ‘last straw’ antecedent

Sometimes there are no definite triggers whatsoever. The cause of the challenging may be overload, i.e. if the child has been struggling already, anything can be last straw. Their sensory perceptual inconsistencies and differences can make dealing with the environment very difficult. If they continue to try to process all the information coming in, despite their inability to keep up with it, it may result in hypersensitivity that eventually bring anxiety, confusion, frustration and stress, that in turn lead to tantrums and difficult behaviors.

  2. I love this so much! There are parents who are going to read this and fall onto the couch and weep with relief!! Thank you so much for writing this!! When a child has a challenge such as autism, the “Antececent” may not look like an antecedent to the adults who are observing the child’s behavior.

    Parents, do you find yourself saying to well-meaning professionals, “I WISH that I were part of the cause of this behavior because then I could change my part and help to create a solution!” If you are working with a professional who is too wedded to the ABC model and your child clearly isn’t responding — because of autism, attachment issues, PTSD, sensory issues, or other causes — PLEASE show them this article! Your child could benefit immensely from the wisdom contained in this article. Hugs and thanks to T.O. Daria and Special Education Advisor!

  3. Excellent points. Because I know my son so well, I am often able to sense when he is at that “last straw” stage. I know if he gets pushed to do just “one more” thing at that point, it’s all over. I think with anyone who has sensory disorders, they’re already being bombarded with so much more stimuli than most people have to deal with all the time and so it appears to others that they have a short fuse, or can’t deal with much noise, etc. Sort of like walking around with a glass of water that’s already half full all the time instead of empty. (The water being sensory stimulation, frustrations, etc. in this metaphor). If your glass is already half full it’ll take much less to get to the point of overflowing where you just can’t take anymore. Hopefully that made sense, I’m half asleep after a rough day of dealing with DS being sick:)

  4. The last straw antcedent is often underestimated.
