The purpose of this study was twofold: (1) to analyze the effects of both personality and environmental variables on the imagination of video/film major university students; and (2) to test the mediator effect resulting from the variable of social climate. The results of this study supported both indicators of imaginative capabilities and environmental influences. The hypothesis of the study—that the variable of social climate mediates the effects of personality/environmental predictors and both types of imagination—was partially supported. The structural model also showed that most personality traits have direct effects on imagination, whereas most environmental predictors have indirect effects. Practical applications of this study were suggested, future inquiries were discussed, and limitations were acknowledged.
