Stress Foundations (Scientific History + Core Concepts)

What Stress Is

  • Stress = the body’s response to demands placed on it (can be external or internal).
    • External demands (examples):
      • extreme temperature/heat
      • claustrophobic environments
      • illness/physical discomfort
      • public fear of ridicule
    • Internal demands:
      • psychological interpretations
      • perceived threats

Why People Respond Differently

  • The key driver is perception/appraisal:
    • A person’s judgment that a situation is threatening or demanding initiates the stress response.
    • Without this appraisal, stress may not fully activate—even if the situation seems serious.
  • Coping belief matters:
    • If someone believes they have ways to cope, the threat may trigger less intense stress responses.

Psychological vs. Biological Stress Responses

  • Psychological schema/stakes
    • Higher stakes (e.g., public evaluation as an adult vs. speaking as a child) can increase perceived stress.
  • Symbolic stressors
    • Threats that are not life-threatening, but are psychologically threatening.
    • Examples:
      • fear of embarrassment
      • fear of being judged
    • The body can react as if there’s a survival threat, even when there isn’t.

Key Wellness / Self-Care Strategies Mentioned

The lecture primarily sets up theory, but points toward stress-reduction methods later and highlights one clear wellness approach:

  • Relaxation training can reduce the stress response
    • Researchers cited (e.g., Benson, Jacobson) found that relaxation helps reduce stress reactivity.

Additional coping strategies were referenced conceptually (without full teaching):

  • Internal coping mechanisms (how you think)
  • External protective factors (support from family/friends/social support)

Stress Research Pioneers and Core Models (Productivity/Mental Health Relevance)

Walter Cannon: Fight-or-Flight

  • When facing a perceived threat, the body prepares to fight or flee.
  • Typical immediate bodily changes described:
    • increased heartbeat
    • perspiration
    • dry mouth
    • tremor
    • muscle tension/posture changes
  • This preparation supports survival by enabling quick responses to danger.

Hans Selye: General Adaptation Syndrome (GAS)

Stress reactivity is described as a 3-phase process:

  1. Alarm reaction
    • initial response to a stressor (recognition that a threat/stimulus exists)
  2. Resistance
    • the body attempts to adapt and cope
  3. Exhaustion
    • prolonged stress depletes energy → illness/exhaustion

Examples used:

  • Biological: fever progression (immune reaction → resistance → illness/exhaustion if prolonged)

  • Psychological: social anxiety at a party

    • could escalate from physiological arousal to exhaustion-type consequences (e.g., illness, blood pressure issues, coronary heart disease)

Use vs. Distress (Richard Lazarus and Related Framing)

  • Stress can stem from:
    • positive demands (eustress), or
    • negative demands (distress)
  • Both can produce similar physiological changes, so life events and context matter for predicting health impact.

Major Life-Event and Daily-Hassle Ideas

  • Life events
    • More significant changes → higher risk of illness onset.
  • Daily hassles
    • Ongoing minor stressors also harm health.
  • Emotional stress differences
    • Emotional stress can affect outcomes even when conditions look similar.
    • Example mentioned: Japanese vs. German concentration camp death rates were attributed partly to emotional stress levels.

Presenters / Sources Mentioned

  • Walter Cannon
  • Hans Selye
  • Lazarus (and Delongis mentioned alongside him)
  • “Simian / Selye’s work contrasted”
    • Lecture text suggests “Simeons” in subtitles; likely referring to Siegel/Simeons (name appears as “Simeons” in subtitles)
  • Greenburg (2012) (example adapted from Greenburg)
  • Benson
  • Jacobson
  • Harold Wolf (1953)
  • Lazarus & Delongis (daily hassles findings)

Note: The lecture cites additional names (e.g., “IED” and “Wolf”), but some appear to be auto-generated/uncertain subtitle spellings. The identifiable sources are listed above.
