In classical conditioning, conditioned responses (CRs) to aversively paired (CS1)rel-ative to unpaired (CS-) face images are often interpreted in terms of the specificindividual displayed in the CS1face image having adopted an aversive emotionalconnotation. This interpretation requires conditioning to rely on an associationbetween CS1face identity and the occurrence of the aversive event (UCS). Here, wetested this requirement assuming that if an association between CS1face identityand UCS occurrence is established, CRs to originally conditioned face images shouldtransfer to novel images of same-identity faces. Forty-eight participants underwentMultiCS conditioning with eight neutral faces as CSs and electric shock as UCS.Central, peripheral, evaluative, and behavioral CRs signaled successful emotionallearning (as reported in Pastor et al., 2015). Behavioral and EEG responses of consec-utive passive viewing showed enhanced reactions to novel angry and happyexpressions of previously shocked CS1versus nonshocked CS- identities, indicatingsuccessful CR transfer within the dimension of face identity. Investigating the natureof CR transfer, EEG revealed an interaction of identity and expression informationduring face processing that followed emotional congruency (i.e., stronger reactions tocongruent angry CS1and happy CS- vs. incongruent angry CS- and happyCS1compounds). While correlates of transfer appeared in late and midlatency timeintervals, the congruency interaction became significant within the first 100 ms offace processing. Our results suggest conditioning to rely on an association of UCSoccurrence with CS1identity and point to fast dynamic interrelations between iden-tity and expression processing. [-]
