Brain & Language
Slowly selects multiple meanings (divergent processing) that are weakly associated.
Primes words that share few semantic features > loosely associated words.
Primes the less frequent meaning of an ambiguous word.
Primes function, collectives, goal-oriented classes.
Priming stays same with more words.
Priming is same for unstructured sentences.
Priming is same for incongruent sentences.
Convergent semantic processing
Divergent semantic processing
… in linguistic tasks which elicit a wide number of responses.
In such tasks, subjects must produce alternate meanings or list as many items as possible.
For instance, the experiment just mentioned can be continued by asking the subject to supply yet another verb, resulting in a response such as ‘(to) throw’.
LHsmall window of temporal integration

low temporal frequency:
slow cues, like vowels
low spectral frequency:
Left hemisphere, fine coding:
9 neurons index 9 regions of space
Right hemisphere, coarse coding:
4 neurons index 12+ regions of space
