Lesson Reach Founder
Anxiety is the most frequently occurring class of mental disorders, affecting 25–30% of the U.S. population over a lifetime — yet not all anxiety is harmful. This lesson from Section 15.4 of Psychology 2e breaks down exactly where normal, protective anxiety ends and a clinical disorder begins, using real examples and evidence-based explanations. From specific phobias and social anxiety to panic disorder and generalized anxiety disorder, we explore the biological and environmental pathways that drive each condition. In this video: • How fear and anxiety differ, and why zero anxiety would actually be harmful to us • Specific phobias: the three learning pathways (classical conditioning, vicarious learning, and verbal transmission) through which fears are acquired • Martin Seligman's theory of prepared learning and why we fear spiders more readily than motorcycles • Social anxiety disorder: how safety behaviors like avoiding eye contact create a self-defeating cycle — and the link to alcohol use disorder • Panic disorder explained as 'the fear of fear,' including the role of the locus coeruleus and norepinephrine in triggering attacks • The asthma-to-panic-attack conditioning example and why panic disorder is nearly three times as common among people with asthma • Generalized anxiety disorder (GAD) as 'free-floating anxiety' — and the paradox that chronic worry may shield against trauma while damaging the heart #OpenStax #Psychology #AnxietyDisorders #MentalHealth #PsychologyEducation OpenStax Content adapted from "OpenStax Psychology 2e", by OpenStax licensed under CC BY 4.0.
