ABSTRACT This study investigated the degree to which students' personality characteristics influence their attitudes toward various learning activities in the language classroom. The research study was conducted with a group of 125 students of Spanish at the university level. The hypotheses of the study were that: 1) Language Class Risktaking positively affects attitudes toward activities involving relatively free language use; 2) Language Class Sociability positively affects attitudes toward activities involving the sharing of ideas or “performing;” and 3) Language Class Risktaking and Language Class Sociability negatively affect attitudes toward highly-structured grammar practice. Multiple regression analysis provided partial confirmation of the hypotheses. The findings suggest the importance of taking personality into consideration in language instruction.
