8. Information FLOW
Information SOURCES
=
Regulated or not?
“The information flowing into our working memory at any given moment is
called our ‘cognitive load’. When the load exceeds our mind’s ability to store
and process the information, we are unable to retain the information or to
draw connections with the information already stored in our long-term
memory.”
Superfluous problem-solving
Divided attention

10. Hypertext:
It will release the reader from the imposed
logic from the author, stimulating the criticism
and the learning process by association.
(George Landow)
“The medium used to present the
words obscured the meaning of the
words.” (Nicholas Carr)

11. “The Net is, by design, an interruption system, a
machine geared for dividing attention.”
“Frequent interruptions scatter our thoughts,
weaken our memory, and make us tense and
anxious. The more complex the train of thought
we’re involved in, the greater the impairment the
distractions cause.”
The switching cost

12. “We want to be interrupted,
because each interruption brings
us a valuable piece of information.
To turn off these alerts is to risk
feeling out of touch, or even
socially isolated.”

13. The F pattern and the scannable reader , by Jackob Nielsen

17. “(...) the constant shifting of our attention when we’re online
may make our brains more nimble when it comes to
multitasking, but improving our ability to multitask actually
hampers our ability to think deeply and creatively.”
Jordan Grafman (head of the Cognitive Neuroscience Unit at the National Institute of Neurological
Disorders and Stroke)

19. “(...) heavy multitaskers were much more easily
distracted by ‘irrelevant environmental stimuli’,
had significantly less control over the contents of
their working memory, and were in general much
less able to maintain their concentration on a
particular task.”
Clifford Nass, Stanford University, 2009
