Component 3: Stress — Eduqas A-Level Psychology

Eduqas A-Level Psychology Component 3: Stress investigates the psychological and physiological aspects of human stress responses. It covers the biology of acute and chronic stress pathways, sources of stress including life changes and daily hassles, individual differences such as the Hardiness personality and Type A/B behaviours, and methods used to measure stress.

The topic also focuses heavily on biological and psychological interventions, requiring learners to evaluate pharmacological approaches alongside cognitive behavioural interventions like Meichenbaum's Stress Inoculation Training. Mastering this topic provides students with essential skills in evaluating empirical studies, distinguishing correlation from causation, and applying psychological concepts to real-world health outcomes.

• →Biological pathways: SAM pathway (Sympathomedullary / acute) causing fight-or-flight and HPA axis (Hypothalamic-Pituitary-Adrenal / chronic) leading to sustained cortisol release.
• →Sources of stress: Differences between major life changes (Holmes and Rahe, SRRS) and minor everyday micro-stressors (Kanner et al., Daily Hassles and Uplifts).
• →Individual differences: Friedman and Rosenman's Type A, Type B, and Type C personality traits, alongside Kobasa's Hardiness model (Commitment, Challenge, Control).
• →Stress management: Biological interventions (beta-blockers and benzodiazepines) compared against psychological therapy (Stress Inoculation Training).

• Describes adrenaline release from the adrenal medulla as part of the acute stress response, raising heart rate and mobilising energy.
• Explains evolutionary adaptation by arguing that a fast fight-or-flight response improved survival in ancestral environments.
• Outlines the role of genetic factors in individual differences in stress reactivity through gene–environment interaction.
• Evaluates an explanation by weighing supporting evidence against limitations such as reduced relevance to chronic modern stressors.
• Identifies at least two individual difference explanations from hardiness, self-efficacy, type A and type B personalities
• Explains the mechanism by which the named characteristic affects appraisal or physiological response to stress
• Supports the explanation with named research evidence such as Kobasa, Bandura or Friedman and Rosenman
• Evaluates the explanation by weighing strengths such as practical application against limitations such as correlational evidence
• Identifies at least two social psychological explanations from daily hassles, life events and locus of control
• Explains how the named factor generates or amplifies stress through cumulative demand or perceived control
• Supports the explanation with named research such as Kanner et al., Holmes and Rahe or Rotter
• Evaluates the explanation by weighing strengths such as real-world application against limitations such as correlational or retrospective data
• Identifies beta blockers as a biological method that reduces the physiological arousal produced by adrenaline and noradrenaline at beta receptors.
• Identifies stress inoculation training as a cognitive-behavioural method that builds appraisal and coping skills rehearsed across stages.
• Distinguishes the symptom-focused action of beta blockers from the skills-building, psychological action of stress inoculation training.
• Supplies at least two named methods, ensuring both beta blockers and stress inoculation training are included.
• Offers a relevant evaluative point, such as side effects of drug treatment or the time and commitment stress inoculation training requires.

• 💡Name the gland and hormone precisely when describing the acute stress response.
• 💡Keep each explanation to mechanism plus one evaluation point to stay concise.
• 💡Link evolutionary accounts explicitly to why the response persists today.
• 💡Name each explanation explicitly before explaining its mechanism
• 💡Link each trait to a specific stress pathway such as appraisal or physiological reactivity
• 💡Use one evaluation point per explanation to show balance
• 💡Distinguish clearly between life events and daily hassles in your explanation
• 💡State whether locus of control is internal or external and link it to stress response
• 💡Balance each explanation with one strength and one limitation
• 💡Read the stem carefully to check how many methods are demanded before selecting an option.
• 💡Link each method to its mechanism, biological or psychological, so similar-sounding options can be eliminated.
• 💡Revise the two named methods as a matched pair, since the specification requires both.
• 💡Always separate biological evaluation into effectiveness (clinical trials, symptom reduction) and appropriateness (side effects, dependency, treating symptoms versus root causes).
• 💡When discussing personality factors, avoid presenting Type A behavior as exclusively linked to Coronary Heart Disease (CHD); specify that later research isolated hostility as the crucial toxic component.
• 💡Use accurate operationalised terminology when discussing the immune system, referencing immunosuppression, lymphocytes (T-cells, NK cells), and Kiecolt-Glaser's medical student studies.

• Attributes adrenaline release to the adrenal cortex; state instead that adrenaline comes from the adrenal medulla.
• Presents evolutionary adaptation as proof rather than an explanatory account; treat it instead as a framework supported by indirect evidence.
• Describes stress genes as directly causing stress; explain instead that they shape reactivity in interaction with environment.
• Confuses self-efficacy with self-esteem; keep self-efficacy as belief in capability to perform a specific task
• Describes type A as simply 'stressed'; keep type A as a behaviour pattern of competitiveness, time urgency and hostility
• Offers only one explanation; include at least two distinct explanations as the statement requires
• Treats daily hassles as trivial and unimportant; keep hassles as cumulative stressors with measurable effects
• Describes locus of control as an emotion; keep locus of control as a generalised belief about the source of outcomes
• Offers only one explanation; include at least two distinct explanations as the statement requires
• Confuses beta blockers with benzodiazepines; keep beta blockers as drugs acting on beta receptors to reduce arousal.
• Describes stress inoculation training as simple relaxation; present it as structured cognitive-behavioural skills training with rehearsal.
• Names only one method; supply at least two, including both required methods.
• Believing cortisol is released during short-term, acute fright. Cortisol is the primary hormone of the chronic HPA axis; short-term acute stress is mediated primarily by adrenaline and noradrenaline via the SAM pathway.
• Assuming the Social Readjustment Rating Scale measures cause and effect. The SRRS produces correlational data; it cannot prove life events directly cause illness due to retrospective recall bias and uncontrolled mediating factors.
• Assuming beta-blockers alter cognitive stress appraisal. Beta-blockers only block peripheral beta-adrenergic receptors, reducing somatic symptoms without treating the psychological origins of stress.
