A personal space of information (PSI) refers to the collection of digital information items created, saved and organized, on digital devices. PSIs play a central and significant role in learning processes. This study explores the mental models and perceptions of PSIs by learners, using drawing analysis. Sixty-three graduate students were asked to make a drawing of their PSI. The analysis of the drawings revealed six types of mental models namely, Hierarchical Model, Organic Model, Technical Model, Process-Based Model, Functional Model and Holistic Model. In a secondary analysis, the mental models were found to reflect three key perceptions of PSIs namely, Instrumental, Symbiotic and Constructive Perceptions. We discuss the possible implications of the different mental models and perceptions on digital literacies. We suggest that facilitating a multidimensional perception of one's PSI (as opposed to a uni-dimensional perception), may lead to a better realization of the potential of PSIs in learning contexts.
