Concurrent Task Management and Prospective Memory: Pilot Error as a Model for the Vulnerability of Experts (2006)
In five of the 27 major U.S. airline accidents between 1987 and 2001 in which the NTSB found crew error
to be a causal factor, inadvertent omission of a normal procedural step played a pivotal role. Such
omissions are a form of prospective memory error. My research group is attempting to link real-world
prospective memory phenomena with task demands and with underlying cognitive processes. I briefly
summarize studies from three quite different but complementary approaches: ethnographic studies,
analyses of accident and incident reports, and laboratory studies. Five types of situation presented
prospective memory challenges: episodic tasks, habitual tasks, atypical actions substituted for habitual
actions, interrupted tasks, and interleaving tasks/monitoring. An experimental study found that inadequate
encoding, inadequate cueing, and competing demands for attention make individuals vulnerable to
forgetting to resume interrupted tasks.
