Effects on the Brain and Learning, and Potential Role of the Schools
Wendy Cunningham, Psy.D.Licensed Clinical Psychologist
ObjectivesObjectivesShow why it is important for alternative schools
to understand trauma and chronic stress
Illuminate current research that links trauma/chronic stress with biology, environment, behavior, and academic performance
Discuss the importance of a systematic approach and why it is important
Few Important NumbersFew Important NumbersDifficult to get prevalence rates; however,
studies estimate between 3.3 and 10 million children witness violence in their home each year
2003: U.S. Department of Health Reported approximately 906,000 children in protective
custody
2005: Massachusetts Department of Education Informal surveys to 450 students of alternative-education
programs in 11 school districts that received state funds90% of the students surveyed reported trauma history
What is a “Traumatic Event”
Many factors involved in what is considered a traumatic event, including:Threat or perceived threat to well-being of self
or otherIndividual temperamentPast experiencesWho is involved in the event
Why events affect individuals in different ways
See Massachusetts Adovcates for Children, (2005). Helping Traumatized Children Learn, Appendix C.
Chronic Stress
See similar biological effects as with traumaLess obvious than a traumatic event
ARE THERE BRAIN EFFECTS?
“I could see the math teacher’s mouth moving in the classroom but couldn’t hear a thing. It
was as if I were in a soundless chamber. She was smiling and clearly talking, I just couldn’t process a word of it. I had been an excellent math student, but the day she told me I was
“spacey” and unfocused was the day I stopped connecting to math. My grades dropped and they took me out of the advanced classes.”
Massachusetts Advocates for Children, (2005). Helping Traumatized Children Learn, p.24.

Emotions: TWO Pathways!Ventral Path (Low
Road)Stimulusthalamusamygdala

Dorsal Path (High Road)

Evolutionary FavoriteWiring of the brain favors emotions
There tends to be more connections directed from the limbic system to the cortex (emotion affects thoughts) versus cortex to limbic system (thought affects emotion)
Theories of EvolutionAlthough hypothetical, theories suggest that we
may move towards more of a balance

What’s the Deal?Incredible Shrinking Brain: Effects on hippocampus
Decreased hippocampal volumeLower hippocampal neural connection
To Stress or Not to Stress: Confused stress responseConsistent survival modeHPA system down-regulates
Unraveling chromosomesChronic stress shown to unravel telomeres (ends of
chromosomes)Unorganized brain – unorganized behavior
• Imprinting (ex. orbitofrontal cortex) and missed stimuli from environmental experiences compromises structural arrangements for regulation
Emotional Memories External Event
Amygdala HippocampusImplicit memory Explicit memory--event was awful --who, what, where--body reaction
*Occurs together to contribute to the experience of the event as a whole
*Not selective in triggers; broad scope
Brain Stressed Out1. Hippocampus
overwhelmed by glucocorticoids
2. Amygdala overwhelms
hippocampus
3. “Talk” between neurons disrupted
4. No new neurons formed
5. Prolonged glucocorticoid exposure might damage or kill hippocampal neurons
Not to Mention Brain Development Issues!
Poor attachment experiences:1.Cognitive deficits2.Brain unable to develop self-regulation3.Poor sequential memory4.Executive functioning poorly developed5.Language instrumental vs. social/emotional
Implications for Learning
Studies show that when compared to other children, maltreated children have:
We Have the Most Difficult Kids!!!!
What Behaviors Do You See?
(Think Brain Influences!)Awareness important, because it can
reduce anger, increase understanding, and improve
intervention
What Can We Do?
See Massachusetts Adocates for Children, (2005). Helping Traumatized Children Learn, Appendix C.
Empirically Supported Interventions Include:
Attachment/relationship focusTraining in affect regulationSystematic desensitization/titrated exposureIndividual therapy
Symbolic play for young childrenAge-appropriate group therapyCaretaker involvement as appropriate
POSITIVE AND COLLABORATIVE TEAM SPIRIT is CRITICAL
Attachment: Not just a nice idea
All research, both biological and psychological, shows that social affiliation and attachment are critical components of mediating effects
of trauma and chronic stress
Attachment Styles, Brain Development, and Behavior
Attachment style psychologically based on view of self & view of other:Secure: positive/positivePreoccupied: negative/positiveDistant: positive/negativeDisorganized/Fearful: negative/negativeResearch shows that traumatized kids largely
exhibit disorganized attachment styleBrain organization in early development relies upon
environment and response of caregiversResearch also shows executive functioning deficits
present in disorganized attachment style that differentiates it from other styles
