People often view the “last” moments of an event positively simply because they signal the end of an experience, say experts.

University of Michigan researchers found that even if an experience is painful or negative, but ends on a good note, people will consider it to be positive.

“Endings are powerful,” said Ed O’Brien, a graduate student in the Department of Psychology at the University of Michigan.

O’Brien and colleague Phoebe Ellsworth, the Frank Murphy Distinguished Professor of Law and Psychology, conducted a chocolate tasting experiment with 52 college students to test the theory.

Volunteers could taste five different Hershey’s Kisses chocolates—milk, dark, cream, caramel and almond – but did not know in advance how many pieces they would eat or the type. Participants rated how much they enjoyed the chocolate and described each flavor so that the researchers could record the order in which the randomly (随机的) selected treats were eaten.

Volunteers were assigned to the “next” or the “last ” condition by chance.

In the “next” condition, the experimenter said “Here is your next chocolate” before offering each chocolate, including the fifth.

For the “last” condition, the experimenter said “Here is your last chocolate” before offering  the fifth chocolate.

These participants rated the fifth chocolate more enjoyable than volunteers in the “next” condition.

As predicted, participants who knew they were eating the final chocolate of a taste test enjoyed it more.

In fact, when asked to pick their favorite chocolate, the majority of “last” participants chose the fifth – even though the flavor of the fifth was randomly chosen.

They also rated the overall experience as more enjoyable than volunteers who thought they were just eating one more chocolate in a series.

O’Brien says these findings may have far-reaching implications. For example, the last book or film in a series or the last speaker in a symposium (研讨会) may receive unwarranted praise.

The last job applicant, meanwhile, may look more qualified.
