Failure of prospective memory is the reason why even the most careful and skilled professionals sometimes forget even the simplest of tasks

The researchers said that one of the major reasons for prospective memory failure is deciding in advance how a task has to be done and getting distracted by the current task on hand and thereby forgetting that a task that had been initially thought was not done.
Dismukes said that while in majority of the times such forgetfulness causes annoyance, it may sometimes lead to disastrous and tragic consequences. “Every summer several infants die in hot cars when parents leave the car, forgetting the child is sleeping quietly in the back seat”, he said. The study has been published in the journal Current Directions in Psychological Science.
