The Impact of Trauma on Behavior and Brain Development Flashcards

TCI teaches that chronic trauma exposure can impair a young person's ability to regulate emotions because it damages which critical developmental capacity?

Answer: The developing prefrontal cortex's ability to manage emotional responses

Chronic stress and trauma impair development of the prefrontal cortex, reducing its capacity to regulate emotional responses generated by the amygdala.

A young person displays a hypervigilant response, constantly scanning the room and startling at small noises. According to TCI, this is best understood as:

Answer: A nervous system adaptation to past danger that is now inappropriately activated in safe settings

Hypervigilance is a nervous system adaptation to chronic threat exposure - the brain remains on high alert even in safe environments because safety was unpredictable in the past.

TCI uses the concept of windows of tolerance to help caregivers understand that young people with trauma histories:

Answer: Have a narrower range of arousal within which they can learn, relate, and function

Traumatized young people typically have a narrower window of tolerance - the arousal range within which they can function - than non-traumatized peers.

According to TCI, one of the most powerful ways to support healing from trauma in young people is:

Answer: Providing consistent, caring relationships that help re-pattern the young person's expectations

Consistent, caring relationships with trustworthy adults are the most powerful healing influence for traumatized young people - they re-pattern relational expectations at a neurological level.

In TCI, understanding developmental trauma rather than only clinical PTSD helps caregivers because:

Answer: Developmental trauma captures the pervasive impact of chronic relational and environmental adversity on development

Developmental trauma is a broader concept that captures the complex, pervasive impact of chronic adverse experiences on a young person's development - beyond what PTSD alone describes.

TCI recognizes that direct care staff can experience secondary traumatic stress (STS) when working with traumatized youth. STS is most accurately described as:

Answer: A trauma response experienced by caregivers through indirect exposure to young people's traumatic stories and experiences

Secondary traumatic stress is a trauma response that caregivers can develop through empathic engagement with the traumatic experiences of those they support.
