One of the original VARK studies noting that women and men separate themselves sharply by these standards. You've probably heard of this research without knowing it, the explanation from the study is"
Students have individual learning style preferences including visual (V; learning from graphs, charts, and flow diagrams), auditory (A; learning from speech), read-write (R; learning from reading and writing), and kinesthetic (K; learning from touch, hearing, smell, taste, and sight). These preferences can be assessed using the VARK questionnaire. ".
The summation of the study that applies here,"
Females prefer unimodal learning, whereas males prefer multimodal learning. Left: 54.2% of females preferred a single mode of information presentation. Of the females who preferred multiple modes of information presentation, some preferred two modes (bimodal, 12.5%), three modes (trimodal, 12.5%), or four modes (quadmodal, 20.8%). Right: 12.5% of males preferred a single mode of information presentation. Of the males who preferred multiple modes of information presentation, some preferred two modes (bimodal, 16.7%), three modes (trimodal, 12.5%), or four modes (quadmodal, 58.3%).".

Mostly focused on communication differences. It agrees with the points Pax and kraigwy made.
