PSYCHOLOGY. For the article “Ecocultural basis of cognition: Farmers and fishermen are more holistic than herders,” by Ayse K. Uskul, Shinobu Kitayama, and Richard E. Nisbett, which appeared in issue 25, June 24, 2008, of Proc Natl Acad Sci USA (105:8552–8556; first published June 13, 2008; 10.1073/pnas.0803874105), the authors note that on page 8554, right column, in the sentence beginning on line 2, the group designations were inadvertently switched. The sentence should read: “All objects in one of the two groups (group 1) had the same stem as the test object, whereas the objects in the other group (group 2) shared a large number of features with the target, although no one feature was shared by all members.” In addition, in Table 1, row 2, column 4, the number of participants with high school education in the Fishermen group was given as 16 and should instead be 22. These errors do not affect the conclusions of the article. The corrected table appears below.
