Recovered memories and egg-salad sandwiches

There has been a lot of controversy over 'recovered memories,' particularly in people who claim to have been abused as children. In a series of experiments reported in the journal Psychological Science researchers falsely suggested that participants had become ill after eating egg salad as a child. Afterwards the researchers offered different kinds of sandwiches to the participants, including one with an egg-salad filling. Four months later the participants were asked to be in a separate study evaluating different kinds of food. Those who had been given the false memories gave the egg-salad sandwiches much lower ratings than those in the control group and were much more likely to avoid eating them.
