This paper seeks evidence of a culture gulf, first voiced by C.P. Snow in 1959, between science and humanities as reflected in the understanding which undergraduate science and humanities majors have of the other field. The 1995 study evaluated responses of students at the University of California Los Angeles (UCLA) and California's Humboldt State University (HSU) to the College Student Experiences Questionnaire, which measures both general cognitive outcomes and personal/social outcomes. The study found some differences between science and humanities majors, although not as great as those reflected in Snow's study of eminent physical scientists and literary intellectuals. The study did find that science majors reported greater progress in analytical skills while humanities majors report greater progress in interpersonal skills. These differences were consistently greater at UCLA than at HSU. The data examining these differences, using Holland's (1959) theory of vocational choice, suggest that they may be the result of institutional environment and context. (Contains 8 references.) (CH)
