How & Why Do We Experience Stress? *perceived threat human stress activates: thoughts, feelings, behaviors, & physiological arousal *normally promote adaptation & survival
Stress & Stressors Stress – physical & mental response to a challenging or threatening situation Stressor – a stressful stimulus, a condition demanding adaptation

Catastrophe Cohen & Ahearn: stages of natural disasters • • • Psychic numbness Automatic action Communal effort Letdown Recovery v. PTS(D)
Physical Stress Response Acute stress – temporary pattern of arousal caused by a stressor w/ a clear onset & offset Chronic stress – continuous state of stressful arousal persisting over time
intense / competitive perfectionist (challenging situations) unstressed / relaxed moderate ambition Personality & Stress
Psychological Responses to Stress Learned helplessness – pattern of not responding to harmful stimuli after an organism learns that its behavior has no effect
• motivation = basic physiological needs – deprived = tense & agitated Øneeds drive action (random) vsuccessful behavior = habit

Universal Emotions
James. Lange theory Cannonbard theory Twofactor theory Stimulus snake Physiological arousal trembling increased heart rate Emotion fear Physiological arousal trembling increased heart rate Stimulus Cognitive interpretation “I feel afraid!” Emotion fear
Emotion: More Than a Feeling A feeling state involving a pattern of facial and bodily changes, cognitive appraisals, and beliefs. Physiological Changes (in body and facial muscles) Emotion Cultural Influences (shape experience and expression of emotion) Cognitive Processes (interpreting the emotional situation)
Theories of Emotion “thalamus” simultaneously sends messages to cortex Fear stimulus
Arousal, Performance, & Inverted “U” function – relationship b/w arousal & performance; ü High Performance Low Arousal Level High
Arousal, Performance, and the Inverted “U” Not all need same arousal Sensation seekers – biological need for higher levels of stimulation than do other people [Opposite: slacker types, slugs, etc. ]
How Are Achievement, Hunger, and Sex Alike? Different? No single theory accounts for all forms of motivation, because each motive involves its own mix of biological, mental, behavioral, and social/cultural influences

The Physical Stress Response Fight-or-flight response – A sequence of internal processes that prepares the organism for struggle or escape Tend-and-befriend model – stress response model proposing that females are biologically predisposed to respond to stress by nurturing and protecting offspring and seeking social support General adaptation syndrome (GAS) – A pattern of general physical responses that takes essentially the same form in responding to any serious chronic stressor Copyright © Allyn & Bacon 2007
The General Adaptation Syndrome Alarm reaction Resistance – the body mobilizes it’s seems to adapt resources to to the presence of the stressor cope with a stressor Level of normal resistance Alarm Reaction Exhaustion – the body depletes it’s resources Successful Resistance Illness/death Resistance Copyright © Allyn & Bacon 2007 Exhaustion
Stress & Immune System Immune system – bodily organs and responses that protect the body from foreign substances and threats Psychoneuroimmunology – Multidisciplinary field that studies the influence of mental states on the immune system Cytokines – Hormone-like chemicals facilitating communication between brain and immune system
Psychological Responses to Stress Resilience – Capacity to adapt, achieve well-being, and cope with stress, in spite of serious threats to development Motivating Yourself Flow – an intense focus on an activity, accompanied by increased creativity and near-ecstatic feelings Involves intrinsic motivation
