eye movements consist of :
fixations: approx 250 ms
Saccades: eye jump from one place to another
what is our perceptual span to left and to right
left: ab 4 characters
right: ab 12-15 characters
eye tracking
the emmediacy hypothesis:
reader tries to comprehend a word as soon as it has been processedf
eye tracking
The eye-mind hypothesis
theres is no delay between the eye looking at a word and the brain processing it
Syntax refers to
the ordering words according to grammatical rules to build meaningful sentences.
Parsing is the process of
computing the syntactic structure of sentences.
N400 (on EEG) is shown when
semantic anomolies
P600 (on EEG) is shown when
inicates syntactic (sentance and grammer) violations
Discourse
spoken/written language that is multiple sentances long
CONSTRUCTION-INTEGRATION MODEL
Van Dijk and Kintsch (1983) proposed that understanding a discourse involves
three levels of representation:
-Surface form- represents the text itself
-Text base/propositional: represents propositions formed from the text (FROG ATE BUG FOR BREAKFAST)
-Situation model- decribes the situation referred to in the text (BUG ATE FROG)
remeber the frog ate the bug, the bug was eaten by the frog etc
Three common types of inferences
– logical, bridging & elaborative
BRIDGING INFERENCES
Help us make information coherent by linking new information to
previously obtained information
LOGICAL INFERENCES
BAsed on formal rules - follow from the meaning of words
100% certain
Elaborative inferences
involve extending what is in the text with world knowledge
