Exam 3 (Reading) Flashcards
Why is reading easier than speech perception? (4 reasons)
- no word segmentation problem
- no parallel transmission (one letter at a time)
- can review (re-read) material
- can control rate of information transmission
In what ways is reading more difficult than speech perception? (4)
- alphabetic characters don’t have unique phonetic equivalents (e.g. boat and hoe v. boat and boa)
- context must be considered to assign phonemes to graphemes (e.g. /ea/ bread vs. bead)
- small area of effective vision - only central area has high acuity
- written language lacks prosody (changes in pitch, etc.)
What is gaze-contingent paradigm?
unfamiliar words and words used to establish context had longer fixation
Eye-contingent displays & moving window paradigm - what was found?
Reading rate increases as window expands from 1 to ~20 letters (3 words)
Eyes move in ___ rather than in smooth continuous motion
saccades
How long is a typical saccade?
7-9 letter spaces
How long is typical fixation and what does it identify?
~200-250ms duration, identifies 1 word
Most content words are ___ but some words get ___.
Fixated, skipped
More content words are skipped if “___ ___” or text is ___.
speed reading, skipped
Regression is related to comprehension difficulties and reader’s skill T/F
True
Perceptual span?
region from which readers take in useful information; limited by vision and attention
What is the typical perception span?
3-4 letters left, 15 letter spaces right. Increases with reading skill
When are there more fixations and shorter movements?
- material is difficult
- long word
- hard to read text
- misspelled word
- low predictability
How can preceding words or sentences influence fixation times?
ex. buttered popcorn vs adequate popcorn
Indirect-Access (speech recoding) Hypothesis
word recognition occurs after phonetic/acoustic recoding
