Researchers Kaitlin Woolley and Ayelet Fishbach (2019) told participants that they were participating in a study on the effects of Hunger. Pairs of participants were told to eat a snack of salsa and chips with a stranger, after which they engaged in a negotiation task. After which, they engaged in a negotation task. Half of the participant-pairs were randomly assigned to share a plate of salsa and chips, and the other half of participant-pairs were randomly assigned to eat their own individual servings. More specifically, the researchers reported that "participants were run in pairs of strangers. We preregistered the study and collected data from 200 undergraduate and graduate students outside a campus cafe (107 female; M=23.57 years, SD=8.80)" What did the researchers mean when they said they "preregistered the study"? a. They registered the study on a website so that students could signup to participate b. They recorded their research design and analysis plan before conducting the study c. They informed the university in advance that they would be recruting participating outside a campus cafe d. They got a special permit to conduct the study that assured participants that they would adhere to ethics guidelines
