1. One-minute papers
Big Points
Surprised by number of shots/commercial
There are differences between writing and video but difficult to characterize
Format does affect content and audience response
Questions
Will WWW and visual media change language learning (that was traditionally
text-based)?
Will we replace writing with visual languages? (See Tonfoni)
What does shot length tell us about impact?
Are there studies of differences in shot lengths in 50s/60s and today?
Will webTV provide another new structure/syntax?
If subliminal messages are illegal, why not web ads? (regulation issue?)
What are the added values of visual elements?
When a movie is made from a book, which contains more info? (bits vs
human cycles)
Are there limits on human info processing rates?
2. Background on Human Information Processing
Card Moran 7 Newell's Model
Three processors:
Perceptual (100 ms [50-200]) analog process
Cognitive (70ms [25-170])
Motor (70 [30-100])
Four memories
Long term (infinite capacity, no decay rate, "semantic coding")
Visual working memory (17 letters [7-17] capacity; 200 ms [70-1000]
decay rate, "physical coding")--used by perceptual processor
Auditory working memory (5 letters [4.4-6.2] capacity, 1500 ms [900-3500]
decay rate, "physical coding")--used by perceptual processor
Working memory used by cognitive and motor processors (3 chunks [2.5-4.1]
pure capacity, 7 seconds [5-226] decay rate for letter, 73 s [73-226] decay
rate for chunk without interference, "acoustic or visual encoding"; if
augmented by LTM, 7 [5-9] chunks capacity. If 3 chunks are processed,
then 7 seconds [5-34] decay rate. I.e., there is a tradeoff between
capacity load and decay.
Some other human-processing rates
