Code is a set of patterns and structures, so it's more visio-spatial than audial.

The problem arises more when trying to memorize words, like in a poem, or during introspection. Also, planning steps and thinking through scenarios is more difficult. People without an inner monologue are less prone to depression and despair because no inner monolog also means no negative self-talk.

I have a really advanced inner monolog, so I tend to do project planning and testing.
