occur more often for both children and the elderly than for adolescents and younger adults
(Jacoby & Rhodes, 2006). [3]
In other cases we may be sure that we remembered the information from real life but be
uncertain about exactly where we heard it. Imagine that you read a news story in a tabloid
magazine such as the National Enquirer. Probably you would have discounted the information
because you know that its source is unreliable. But what if later you were to remember the story
but forget the source of the information? If this happens, you might become convinced that the
news story is true because you forget to discount it. The sleeper effectrefers to attitude change
that occurs over time when we forget the source of information (Pratkanis, Greenwald, Leippe, &
Baumgardner, 1988). [4]
In still other cases we may forget where we learned information and mistakenly assume that we
created the memory ourselves. Kaavya Viswanathan, the author of the book How Opal Mehta
Got Kissed, Got Wild, and Got a Life, was accused of plagiarism when it was revealed that many
parts of her book were very similar to passages from other material. Viswanathan argued that she
had simply forgotten that she had read the other works, mistakenly assuming she had made up
the material herself. And the musician George Harrison claimed that he was unaware that the
melody of his song “My Sweet Lord” was almost identical to an earlier song by another
composer. The judge in the copyright suit that followed ruled that Harrison didn’t intentionally
commit the plagiarism. (Please use this knowledge to become extra vigilant about source
attributions in your written work, not to try to excuse yourself if you are accused of plagiarism.)
Schematic Processing: Distortions Based on Expectations
We have seen that schemas help us remember information by organizing material into coherent
representations. However, although schemas can improve our memories, they may also lead to
cognitive biases. Using schemas may lead us to falsely remember things that never happened to
us and to distort or misremember things that did. For one, schemas lead to the confirmation bias,
which is the tendency to verify and confirm our existing memories rather than to challenge and
disconfirm them. The confirmation bias occurs because once we have schemas, they influence
how we seek out and interpret new information. The confirmation bias leads us to remember
