BibTeX does not have the right entry for preprints. This is a hack for producing the correct reference:
@booklet{EasyChair:3823,
author = {Davis Whaley and Kathryn McCarthy},
title = {Effects of Domain-Specific Knowledge on Literary Text Processing: A Think-Aloud Investigation},
howpublished = {EasyChair Preprint 3823},
year = {EasyChair, 2020}}
