Studies suggest that :-
(a) Attention span is limited to about 20 minutes
(b) About 20% of auditory material presented is retained
(c) About 30% of visual material presented is retained
Consequently, the 10 minute presentation adopts a conservative approach to the "20 minute" rule, and
verbally presents a chosen article in which five key points have been highlighted. All participants are
provided with a copy of the chose article, and discussion follows.
