Ira Fischler, David Goldman, Mireille Besson, Michael McKay,
& Margaret Bradley. Effects of Emotionality of Words in Word
Phrases on Event-Related Brain Potentials.
Previous work has shown that viewing of individual
emotionally evocative words (e.g., pleasure, rape) is associated with an
enhanced late positivity in the event-related brain potentials (ERPs)
to those words, beginning as early as 350 ms after word onset. In the present
study, emotional and neutral words were combined into two-word modifier-noun
phrases (e.g., starving puppy) and presented visually with an SOA of 750
ms. When the task focused attention on the word pair as a phrase
(Experiment 1), effects of the emotionality of the first word on
the ERPs were absent, and those to the second word enhanced, compared to
a task that focused attention on the individual words (Experiment 2). There
was little effect of the emotional congruence between modifier and noun
on the ERPs. These results suggest that in normal discourse processing,
the emergent emotional meaning of the phrase can supercede, rather than
follow, any automatic emotional responses to individual words.
