This document summarizes Zohreh Sharafi's research on the influence of representation type and gender on program comprehension. The research includes several experiments that investigate how representation type (graphical vs. textual) and gender influence developers' efficiency, effectiveness, and viewing strategies during program comprehension tasks. The results show that developers prefer graphical representations and find relevant information faster with graphical representations compared to textual. The experiments also found that men and women use different strategies to select correct answers, with women taking longer but achieving higher accuracy. Further analysis revealed differences in how men and women distribute their visual attention across source code entities during comprehension tasks.
