Main Topics
|
One:
Hal
and Me
|
2008
– Research and consulting firm nGenera released study: For people who have
grown up using the web, the “digital immersion has even affected the way they
absorb information” (p. 9). They don’t follow traditional right to left, top
to bottom pattern; instead, they jump around.
Carr
himself reported loss of ability to pay attention. Also, constant desire to
get new information from the Net. He “always
wanted to be connected.” (p. 16)
|
Two:
The
Vital Paths
|
Michael
Merzenich – 1968 – First to discover brain’s plasticity in monkeys.
Hebb’s
rule – cells that fire together wire together.
Brain
constantly in a state of change; adapts to the smallest changes in
circumstances, behavior,
& thinking.
Once
new pathways are formed, they want to stay; thus, habits, addictions, mental
symptoms.
Use it or
lose it.
Survival of
the busiest.

Three:
Tools
of the Mind
|
Four outcomes of technology:
1.
extend our physical strength (plow,
fighter jet)
2.
extend our senses (microscope, Geiger
counter)
3.
reshape nature (birth control)
4. extend mental powers (map, clock, computers)
Two views
of technology’s role; both supporting “technological advances mark turning
points in history":
1.
determinism – is outside of man’s
control, eventually will make man dispensable.
2. instrumentalists – man uses technology to
achieve what he wants.
Speaking
and understanding verbal words is innate.
Reading and
writing are learned skills – they require shaping of the brain.
|
Four:
The
Deepening Page
|
Reading
– there are particular regions of brain devoted to deciphering of text. This
becomes automatic. Then, able to focus
on meaning.
Readers’
brains become able to ignore distractions and sustain attention.
Many report
a change in consciousness when “immersed” in a book.
|
Five:
A
Medium of the Most General Nature
|
2009
– Time people spent online increased
rapidly, but no decrease in
time spent watching television. Decrease in time spent reading.
“We
don’t see the forest when we search the web. We don’t even see the trees. We
see twigs and leaves” (p. 91).
People
using Internet more and other media
less (music CDs, movie DVDs,
newspapers).

Six:
The
Very Image of a Book
|
Benefits of
books over digital readers:
Advantages
of digital reader:
|
Seven:
The
Juggler’s Brain
|
Surfing the
web “promotes cursory reading, hurried and distracted thinking, and
superficial learning” (p. 116).
It is
multi-sensory: hands and fingers, visual, auditory.
We don’t
really “read” when browsing the web. Our eyes mostly scan the screen.
Constant
source of new information overloads the working memory.
Readers
of “linear texts comprehend more, remember more and learn more than those who
read text peppered with links” (p. 127).
Brain activity:
Reading – language, memory, visual
processing, brains more calm in experienced readers.
Surfing
the Web – decision-making,
problem solving, helps keep minds sharp. Strengthens lower-level cognitive
skills: hand-eye coordination, reflex response, processing visual cues,
fast-paced problem solving.
|
Eight:
The
Church of Google
|
Larry
Page and Sergey Buin – founders of Google. They see information as a
commodity with the goal to access and process as much information as possible
as quickly as possible.
Carr
– need both “efficient data collection and inefficient contemplation”(p. 168).
We live in
a time of “information overload” (p. 170).
|
Nine:
Search,
Memory
|
Computer’s
memory: limited space, information
immediately saved as entered, never changes.
Human
long-term memory: no limit, continues to process information after received,
constant state of renewal.
|
Ten:
A
Thing Like Me
|
ELIZA
– Computer program that can carry on conversation playing off what human
responded. Developed by Joseph
Weizenbaum.
Alan
Turing – Turing Test – can a person distinguish between a computer and a
human respondent?
John
Culkin, 1967 – “We shape our tools and thereafter they shape us” (p. 210).
Christof
van Nimwegen, 2003 – Experiment involving problem solving with and without
help of computer. Those without help solved problems quicker
and more efficiently. Also, group without
help solved similar problems quicker and more efficiently 8 months later.
|
For Discussion:
1. In Chapter 10, Culkin states that we
are shaped by the tools we create. How have humans changed due to new
technologies? What are the positives and
negatives?
2. This book focused on the downside of
brain changes due to computers, what are the positives?
3. Have you experienced any of the following
described by the author:
* Loss of ability to pay attention and
focus?
* Desire to constantly be connected?
* Being “lost” in a book – a calmness of
the brain when reading?
4. Where should research go next?
