Event Abstract Back to Event Event related field (ERF) correlates of visual attentional processing during experimentally induced sad and happy mood states: an emotional rapid serial visual presentation (RSVP) paradigm. Louisa Coulson1*, Sven Braeutigam1, Morten Kringelbach1 and Klaus Ebmeier1 1 University of Oxford, United Kingdom Previous studies report emotion-related, mood-congruent information processing biases in patients with Major Depression. We examined whether rapidly presented emotional word stimuli influenced visual attentional processing; recruiting a sample of 24 psychiatrically healthy participants following induced neutral and sad (n=12) or happy (n=12) mood. Mood induction procedures (MIPs) by means of self-referential statements and music were used to manipulate mood. We developed an emotional version of an RSVP paradigm wherein participants were instructed to identify a neutral yellow (T1) and neutral or emotional green (T2) word in a rapidly presented visual stream of distractor items (5 letter consonant strings). The attentional blink (AB), a phenomenon identified in RSVP paradigms, is the reduced ability to identify the second target word (T2) when participants are also required to identify the first target word (T1). We hypothesised that the AB would be associated with suppression of ERFs at 300-450ms (M3 component) and 450-600ms (M4 component) post-stimulus onset in left frontal and inferior parietal cortices. This effect would be reduced when T2 valence was congruent with the participants’ mood state, i.e. negative T2 following a sad MIP. Sad and happy MIPs altered mood state in the expected directions. A preliminary analysis of the behavioural data for the first 18 participants to complete the study following neutral and sad (n=8) or happy (n=10) MIPs was conducted. We found a main effect of duration (p<0.001) wherein a shorter latency between T1 and T2 presentation was associated with a larger proportion of T2 blinked trials. However the predicted interaction of mood*valence could not be found. A time-locked analysis of magnetoencephalography (MEG) data for T2 blinked trials will be presented to investigate the predicted effects, and beamformer analysis will utilise MRI data to model the sources of the electrophysiological brain activity.
