Flashbulb memories feel certain but drift like any other

Correct: B — People feel high confidence in flashbulb details that are nonetheless inaccurate or change over time

Brown & Kulik (1977) coined 'flashbulb memory' for the vivid, detailed, long-lasting recall people report for shocking events. Subsequent prospective studies — including Hirst et al.'s ten-year longitudinal study of 9/11 memories — show that confidence stays sky-high while accuracy drops at roughly the same rate as ordinary autobiographical memory, with substantial month-to-month inconsistency. The phenomenology of certainty is dissociated from accuracy. Emotion appears to enhance the subjective vividness of the trace and the central gist, but does not protect it from the same reconstructive distortions that affect mundane memories.
