Lecture 2 - Stress

This lecture provides a comprehensive examination of psychological stress, exploring its definitions, biological mechanisms, and developmental impact. The speaker explains that stress results from the interaction between external demands and an individual’s internal resources, rather than just external events or physical reactions alone. Key concepts discussed include the "fight, flight, or freeze" response triggered by the sympathetic nervous system and the harmful effects of chronic cortisol and adrenaline release. The text details Hans Selye’s General Adaptation Syndrome, outlining the stages of alarm, resistance, and exhaustion that occur during prolonged pressure. Furthermore, the source examines how stress manifests across the human lifespan, from the trauma of birth to the challenges of adolescence and the transitions of old age. Finally, the lecture introduces the Locus of Control concept, emphasising the importance of moving toward an internal sense of agency to improve mental resilience and therapeutic outcomes.
