Just to offer a different (different from Danahoe & Palmer) point of
view for those readers who want to stay within todays popular field of
theoretical cognitive research, Baddeley & Hitch's tripartite Working
Memory model (start with : Baddeley, 1986) offers a theoretical
cognitive framework to methodologically support and discuss applied
user-system research on multimodality. This Working Memory model does
have a "central executive" to *co-ordinate* (a) the activity of a
phonological loop and (b) the handling of visio-spatial information.
For example, to drive a car, and simultaneously use a mobile phone,
will influence the controlling attential mechanism ("central
executive"), and probably increase the total number of accidents.
