The document describes a student named Kwon So-yeong conducting their own Implicit Association Test (IAT) to test whether they have an implicit preference for domestic or foreign-made products. The IAT involves sorting words into categories of "Good" versus "Bad" and "Domestic products" versus "Foreign-made articles". The results showed the student unconsciously associating foreign-made articles more strongly with "Good" words and domestic products more strongly with "Bad" words, revealing an implicit preference they did not explicitly recognize.
