A Life Across the Lifespan

Following one person across development means tracing temperament, attachment, cognitive stage, psychosocial conflict, and trait stability from infancy through late adulthood.

One life traced end to end: the temperament visible in the first months, the attachment pattern formed with it, the cognitive capacities that arrive in sequence, the psychosocial conflicts met at each stage, the adolescent brain development that shapes a decade, the trait profile that stabilizes and then continues shifting slowly, and the abilities that decline and the ones that do not. Ends by naming the three points where the evidence supports prediction and the two where it does not.
