Triggered by challenges, it releases hormones like adrenaline and cortisol to prepare the body for "fight or flight". While short-term stress can motivate, chronic stress can lead to exhaustion, or "burnout".Aspects of Stress: Physical Response: Includes rapid heart rate, muscle tension, headaches, and fatigue. Emotional/Mental Response: Feelings of being overwhelmed, irritable, anxious, or unable to concentrate.Types of Stress Acute Stress: is a short-term, intense reaction to a traumatic event or high-pressure situation, often involving a "fight-or-flight" response. Eg losing your phone Episodic Acute Stress: occurs when someone experiences frequent, the stress become the way of life recurring episodes of high tension. Chronic Stress: Long-term, unrelenting pressure arising from situations like poverty, unhappy marriages, or a demanding job.Explain what is alternative perspective of stress Alternative perspectives on stress reframe it not just as a negative, harmful force, but as a neutral, or even positive, experience that can drive personal growth, resilience, and enhanced performance. Shifting from a distress-only view to seeing stress as an adaptable challenge helps to manage psychological and physiological responses.Cont…. An alternative perspective of stress moves away from the traditional view of it being purely a negative "fight-or-flight" physiological response to danger. Instead, these perspectives frame stress as a transactional process, a motivational tool (eustress), or a social/systemic experience.alternative perspective of stress Transactional/Cognitive Appraisal Perspective: Developed by Lazarus and Folkman, this view argues that stress is not simply caused by an external event, but by how an individual appraises that event. It is a transaction between a person and their environment involving: Primary Appraisal: The individual evaluates whether a situation is a threat or challenge. Secondary Appraisal: The individual assesses what resources (social, personal, environmental) they have to cope with the situation.Cont… Conservation of Resources (COR) Theory: Proposed by Hobfoll, this approach views stress as a reaction to the threat or actual loss of resources (e.g., social support, money, time, health). Rather than just reacting to pressure, stress occurs when people feel their valuable assets are being depleted.Cont… Eustress (Positive Stress) Perspective: This perspective recognizes that not all stress is harmful (distress). Eustress is positive, moderate stress that acts as a motivator, increasing focus and energy to achieve goals, such as training for a marathon or meeting a challenging deadline.Cont. The "Relaxed State" or Thought-Based Perspective: This suggests that stress is not caused by external circumstances, but by our own "thinking" filling our mental capacity. It highlights the "freedom of thought" to choose how we interpret situations, arguing that by not filling our mental space with stressful thoughts, we can remain in a natural state of calm.Cont….. Systems/Allostatic Load Perspective: This views stress as a "systems-level" problem where the body's attempt to maintain stability (homeostasis) becomes overloaded over time, leading to "allostatic load" or "cacostasis"—a state where the cost of adaptation leads to damage.Cont.. Gender-Specific (Tend-and-Befriend) Perspective: An alternative to the "fight-or-flight" response, this theory suggests that under stress, people (often women) may engage in "tend-and-befriend" behaviors protecting offspring and seeking social support rather than just running or fightingExplain stimulus-based perspectives and life event scales Stimulus-based perspectives and life event scales represent a, primarily, "cause-focused" approach to understanding stress in psychology. This viewpoint defines stress not by an individual's reaction, but by the external events or situations stressors that place significant demands on a person, requiring adaptation, change, or coping.Stimulus-based perspectives on stress Define it as an external, objective event, situation, or life change that demands a person to adapt, often exceeding their resources. This perspective emphasizes measuring the stressor itself rather than the individual's subjective emotional reaction to it.CONT… The stimulus-based perspective (developed largely in the 1960s) argues that stress is an independent variable in the health-stress-coping equation; it is the cause of an experience, not the experience itself. Definition: Stress is viewed as a life event, situation, or environmental trigger that necessitates a change in a person's life. Focus: It focuses on external, often objective, occurrences (e.g., job loss, marriage, moving) rather than internal subjective feelings. Mechanism: It assumes that when these environmental demands exceed an individual's adaptive capacity, they produce stress. Limitation: It is critiqued for failing to account for individual differences in how people perceive, interpret, and react to the same stimulus.Life Events Scale refers to a standardized measure used to assess major life events, which aims to minimize bias by removing non-stressful events and specifying a recall period, although it may still be subject to issues like underreporting and subjective interpretations.CONT… Life event scales are tools designed to measure and quantify stress based on the stimulus-based perspective. The most famous is the Social Readjustment Rating Scale (SRRS), developed by Holmes and Rahe in 1967. Structure: The SRRS consists of a list of life events, ranging from major (death of a spouse) to minor (minor violations of the law). Scoring (Life Change Units): Each event is assigned a numeric weight Life Change Units indicating the amount of change/readjustment required. Purpose: The goal is to calculate a cumulative stress score over a specific period (usually 6 to 12 months) to predict the likelihood of developing physical or mental illness. Key Findings: Research using these scales suggests that both positive (e.g., marriage) and negative (e.g., divorce) changes require adaptation, and a high
