Abstract
The social content of affective stimuli has been proposed as having an influence
on cognitive processing and behaviour. This research was aimed, therefore, at studying
whether automatic exogenous attention demanded by affective pictures was related to
their social value. We hypothesized that affective social pictures would capture
attention to a greater extent than non-social affective stimuli. For this purpose, we
recorded event-related potentials in a sample of 24 participants engaged in a digit
categorization task. Distracters were affective pictures varying in social content, in
addition to affective valence and arousal, which appeared in the background during the
task. Our data revealed that pictures depicting high social content captured greater
automatic attention than other pictures, as reflected by the greater amplitude and shorter
latency of anterior P2, and anterior and posterior N2 components of the ERPs. In
addition, social content also provoked greater allocation of processing resources as
manifested by P3 amplitude, likely related to the high arousal they elicited. These
results extend data from previous research by showing the relevance of the social value
of the affective stimuli on automatic attentional processing.
