Essentially, all behavior is a function of a few basic events: You can see from this analogy that the omelet (our stand in for behavior) is both a function of some events, and functions to change some other events. The omelet, for example, is a function of eggs, milk, a whisk, a pan, and some heat the omelet functions to reduce hunger, increase energy, impress your mother-in-law, maybe. This refers to how the behavior works (functions) as part of the environment. Technically, the reasons for behavior are called functions. Functional behavior assessment (FBA) and functional analysis (FA) are ways to figure out what causes behavior.

There are many variables that have to come together to cause a behavior. Behavior is a little like that no single event or ingredient leads to behavior. To cause an omelet, you need lots of ingredients and events to come together in the right way. Maybe it is going into the kitchen and getting a whisk? Still not the only thing that causes an omelet. Is it the grumble in your stomach that makes you grab a pan and turn on the stove? Not alone. Consider the omelet – what CAUSES an omelet? Is it just eggs? No. To illustrate the complexity of identifying causes of behavior, let’s use a food analogy. So what causes behavior? As you may suspect, this is not a simple answer. What is behavior? Behavior is any interaction between someone and the environment. What causes behavior? To start to find a cause, we want to first define behavior itself. Now, you are left with the question: why did my child do that?


They look at you and you say, “don’t step on the cereal it will make a mess!” They lift their foot while looking at you and stomp on it. Imagine your child just dropped cereal all over the kitchen floor.
