Eide Neurolearning Blog: Voluntary Control of Attention - Visual and Auditory Multi-Tasking
There is a yin and yang effect between visual and auditory attention. When one is looking, then auditory processing areas go down, and when one is listening, then visual processing areas go down. Mixed visual-auditory stimuli have an underadditive effect, so that if you have to do both at the same time, total brain activation goes down, and interestingly, language processing becomes more left hemisphere-dominant.

"To put it into perspective only two to four percent of the world's botanical and zoological species are in serious danger, whereas it's 50 percent of languages. The language crisis hasn't attracted the same degree of public awareness".
How Interactive are YOUR Distance Courses
However, studies such as
one by Miller and Webster (1997, December) have found no significant
difference in assessments of interaction between students in
a synchronous (face-to-face) and asynchronous courses. Horn (1994)
and Hirumi and Bermudez (1996) are among those who find that,
with proper instructional design, distance courses actually can
be more interactive than traditional ones, providing more personal
and timely feedback to meet students’ needs than is possible
in large, face-to-face courses.
