How did the experimenters mislead participants in the Andrade study?

In the Andrade study, participants were misled effectively through claims regarding the need for them to remember names during the task. The experimenters assured participants that they would not need to recall any information, which created an environment where participants might not have anticipated the requirement to remember names later. This misleading information effectively set up the experiment so that when participants were later asked to recall names, they were caught off guard and their performance ratings might reflect their actual cognitive engagement with the task rather than their expectation of recall, which was falsely downplayed. This is crucial to understanding the interplay between expectation and memory recall within the context of the study.
