- HarriS, Schoen, and Hensley (1992) conducted a research study showing how cultural experience can influence memory. They presented participants with two different versions of stories. One version contained facts or elements that were consistent with a U.S. culture and the second version contained material consistent with a Mexican culture. The results showed that the participants tended to make memory errors for the information that was not consistent with their own culture. Specifically, participants from Mexico either forgot or distorted information that was unique to U.S. culture, and participants from the United States forgot or distorted information that was unique to Mexican culture. The following data represent results similar to those obtained by Harris, Schoen, and Hensley. Is there a significant difference between the two groups? Use a two-tailed test with a == .05.
Number of Errors Recalling the Mexican Story
Participants from Mexico n == 20 , M == 4.1 , SS == 180
Participants from the United States n == 20 , M= 6.9 , SS == 200
