Resources

Question 1

In general, we allocate most of resources to focus on the _______, while little resources are left to focus on the ________ _________.

Answer 1

meaning; irrelevant information

Question 2

Performance Operating Characteristic (POC) Graph

Answer 2

Plots dual task performance as a function of task priority and looks at how performance varies between tasks as we change their priority.
->will use more resource when is our priority

Question 3

The slope of the POC indicates…

Answer 3

relative efficiency

Vertical/horizontal line= data limits

Question 4

POC has __ tasks and PRF has __.

Answer 4

2;1.

-> PRF doesn’t include tradeoff from multiple tasks

Question 5

Rapid serial visual presentation (an application of resource theory to attention in time) shows that…

Answer 5

Comprehension is efficient; words or pictures can be understood and recalled when presented at high rates.

Question 6

Eyes alternate between______ s and ______s, with usable visual information only in _______s.

Answer 6

fixations; saccades; fixations

Question 7

In the reading speed task, the typical fixation lasts _____ms

Answer 7

250 ms; since most words fixated at least once, implies reading speed of 250 wmp.

Question 8

Saccades

Answer 8

very rapid movement of eyes to a different point

Question 9

In the RSVP Presentation task (sentence words flashed very quickly), words are commonly detected/recalled at _____ms/word

Answer 9

100 ms/word (more than 2x normal reading rate)

Question 10

RSVP presentation suggests that word recognition is not rate limiting, but is ________.

Answer 10

(largely) automatic

Question 11

In the RSVP task, comprehension is _____ over sustained intervals.

Answer 11

Weak

-> comprehension is more than simply recognition

Question 12

2 Comprehension limits in RSVP?

Answer 12

1. Repetition blindness

2. Attentional blink

Question 13

Repetition Blindness

Answer 13

Repeated RSVP items are often not reported, explained by the relatively inefficient processing of context. ->activating same word detector, need context to realize repetition
-> doesn’t occur for sound, letter case, or meaning, but does for spelling even when sound is diffferent=> means based on representation of word spelling, not appearance.

Question 14

Attentional Blink

Answer 14

• RSVP presentation w/ 2 targets
• Second target often missed at short lags (shortly after 1st)
• Implies target retention is resource limited.
