Positive psychology

Positive psychology is the branch of psychology devoted to the scientific study of human flourishing — the strengths, emotions, and conditions that make life worth living. Championed by Martin Seligman in the late 1990s, the field emerged as a deliberate counterweight to psychology's traditional emphasis on disorder and dysfunction: instead of asking only what goes wrong in the mind, it asks what goes right.

The field studies measurable constructs: subjective well-being and life satisfaction, optimism, gratitude, resilience, character strengths and virtues, and flow — the state of complete absorption in a challenging, skill-matched activity described by Mihaly Csikszentmihalyi. Seligman's PERMA model organizes well-being into five elements: positive emotion, engagement, relationships, meaning, and accomplishment.

Positive psychology is not the claim that people should simply think happy thoughts. Its contribution is empirical: researchers test whether specific practices — gratitude journaling, savoring, using signature strengths in new ways — reliably increase well-being, and how factors like strong social relationships relate to health and longevity. Findings from this work inform therapy, education, and workplace design, and connect directly to health psychology's interest in how psychological states affect physical health.

The AP Psychology exam covers positive psychology in its mental and physical health unit — students should be able to define the field's aims, name researchers like Seligman, and identify concepts such as flow, gratitude, resilience, and the elements of well-being.
