Stress Flashcards
What is Stress?
A state of threatened homeostasis provoked by a psychological, biological, or physiological stressor
Acute stressor
Short-term stressors, non-frequent
Ex. Late for class
Chronic Stressor
Prolonged, long-term stressors that may take extended period of time to resolve
Ex. terrible roommate
What is cortisol?
- Stress hormone
- Responsible for alertness, and can trigger the release of glucose from liver to increase energy
Why is you cortisol high when you wake up?
Helps you wake up and prepare to start your day
- Cortisol Awakening Response
What is the Adaptive Calibration Model?
- Individual differences in stress responsively are largely the result of conditional adaption
What does externalizing refer to?
- Defiance, impulsivity, aggression & antisocial behavior
True or False: Lower cortisol is associated with higher learning/ memory
True
- Higher cortisol is associated with poor learning/ memory
What is threat?
- Presence of experiences that represent a safety threat
What is deprivation?
- Absence of expected environmental inputs
In what ways does cortisol affect your body?
-Metabolism: decreases it
- Inflammation: weak immune system
- Blood-pressure: high
- Blood-sugar: high; type 2 diabetes
- Sleep-wake cycle: can’t sleep
What is a Sensitive Response Pattern?
- A type of Moderate response
- AUCg & AUCi, but activate minor stressor - Found in youth who:
- Infrequent HPA activation
- Genetic Predisposition - Youth will be:
- Reflective & Conscientious
- High in inhibitory control & executive function - Consequences of environmental mismatch
- Large stressor environment
- individual HPA axis is constantly firing
What are children who experience adversity at risk for?
- Irregular regulation of emotions
- Risk for developing psychopathology
What is a Buffered Response Pattern?
- It is a moderate response
- AUCg & AUCi; not as sensitive to stress as sensitive pattern - Found in youth who had moderate HPA activation in 1st year
-Less sensitive to stressors - Can present as “protective factor”
How does Bottom-Up Processing work?
-Brain and limbic system
to
- Higher cortical regions
What are some types of physiological markers of stress?
- Autonomic Nervous System
- Inflammation
- Respiratory Sinus Arrhythmia
-HPA Axis
What is the Autonomic Nervous System?
- it controls vital functions such as heartbeat, breathing, & digestion
- Activates very fast
- Measured by salivary alpha-amylase & norepinephrine
How does inflammation work with stress?
- Measured by IL-6 (protein)
- When body is inflamed, we are at risk for being sick
How is Respiratory Sinus Arrhythmia response with stress?
- Closer beats means there’s more stress
- Measured by assessing heart rate, rhythm & the intervals between heart beats
What is the HPA axis?
- Measured by cortisol
- Cortisol peaks after 15-20 minutes after stress exposure
What does HPA stand for?
Hypothalamic-pituitary-adrenal axis
What is the order of the HPA axis activates?
- Hypothalamus
to - Pituitary
to - Adrenal Glands
Where are the adrenal glands located?
- On top of the kidneys
What is area under the curve with respect to ground?
- Measures total hormonal output
- Values can only be positive
