Trigger warning: This topic is disturbing and sensitive, yet I wish more behavior analysts applied their science to this ugly real world problem.  Let’s face the hard thing together, by discussing some effects of initial learning on later behavior and learning. Several references are below for this topic: How acquisition predicts extinction; variability during acquisition and extinction. This article is Part 11 in a series on how behavior analysts can grow towards supporting children and adults affected by trauma, by Dr. Camille Kolu, Ph.D., BCBA-D.

Severely aversive experiences affect us for a long time. And acquisition can predict what someone’s behavior will look like during extinction (or how behavior will depend on original learning even long after those variables are “gone”). A BCBA recently asked me for references on this topic during a training I provided to an autism agency on how to provide safer and more appropriate supports for individuals affected by events we characterize as “traumatic”. Thank you to the BCBA for the excellent question!

At first try, we might have a hard time finding references and resources showing how a young child’s traumatic history leads to bizarre and challenging behavior much later in life. If this seems strange, consider how absurd it would be to suggest that caregivers are carefully documenting and reporting how they deprived a child of the food, comfort, diaper changes and other kinds of care the child needed as an infant or growing young person. These tragic events are usually documented after, not while, they occur (if ever). But at least scientists can get familiar with how early learning affects later learning, and behavior later in life. This helps us to make sense of otherwise bizarre behaviors, provide important contextual information to caregivers and decision makers, and even to inform our preventative treatment of behaviors that don’t seem related to the ongoing situation.

Behavior analysts or psychologists might relate this to how early learning conditions affect subsequent learning, or how the variables present during early learning exerts effects on behavior, after that situation is no longer present. This discussion is to provide some examples of literature that might be useful for behavior analysts interesting in exploring this topic.

In my work with children and adults after traumatic experiences before and during foster care (or other traumatic events including long duration life threatening illnesses or aversive experiences), I have been collecting data on the types of behaviors that “show up in the behavior stream and repertoire” of children who were exposed earlier – and in some cases much earlier- to situations of neglect and abuse.
