Prior reports suggest that affective effects in visual word processing cannot be fully
explained by a dimensional perspective of emotions based on valence and arousal.
In the current study, we focused on the contribution of approach and avoidance
motivational systems that are related to different action components to the processing
of emotional words. To this aim, we compared frontal alpha asymmetries and brain
oscillations elicited by anger words associated with approach (fighting) motivational
tendencies, and fear words that may trigger either avoidance (escaping), approach
(fighting) or no (freezing) action tendencies. The participants’ task was to make decisions
about approaching or distancing from the concepts represented by words. The results
of cluster-based and beamforming analyses revealed increased gamma power band
synchronization for fear words relative to anger words between 725 and 750 ms, with
an estimated neural origin in the temporal pole. These findings were interpreted to
reflect a conflict between different action tendencies underlying the representation of fear
words in semantic and emotional memories, when trying to achieve task requirements.
These results are in line with the predictions made by the fear-hinders-action hypothesis.
Additionally, current data highlights the contribution of motivational features to the
representation and processing of emotional words
