We interpret this finding in terms of a behavioural indicator of affective learning in MultiCS conditioning that is observable on an implicit response level but absent for more explicit measures. However, contrary to most previous affective priming studies using primes with an explicit emotional value (e.g. Hermans et al., 2002; Spruyt et al., 2007), we found faster RTs for evaluative decisions after affectively incongruent

rather than congruent priming. Although affective priming effects have been reported to become reduced or even inverted in specific settings, i.e. for dismissive answers in tasks requiring negation or affirmation (Wentura, 1999; Klauer & Musch, 2003), to our knowledge the present result pattern of faster responses in the incongruent condition has not previously been reported selleck inhibitor in the literature on similar affective priming procedures. However, a similar inversion of congruency effects between supraliminal and subliminal aversive cues has recently been shown in a series of affective www.selleckchem.com/products/DAPT-GSI-IX.html spatial cuing studies (Raes et al., 2010). Raes et al. (2010) interpreted this finding as an indicator of affective learning in the absence of contingency awareness, which is corroborated by the results of the present affective priming task with subliminal affective stimuli. The present study demonstrated rapid and highly resolving affect-specific auditory processing of multiple shock-conditioned

relative to unpaired click-like tones within a distributed neural network of prefrontal and parietotemporal cortex regions. Relative increased neural activation for aversive and unpaired tones occurred in the right and left hemispheres, respectively, in line with the proposal of two partially separable neural systems supporting withdrawal- and approach-related emotion (Davidson & Irwin, 1999). Notably, early cortical

processing was modulated Org 27569 after few learning instances and in the absence of awareness for the contingent CS–UCS relationship. An indirect measure of stimulus valence indicated that affective associative learning during MultiCS conditioning indeed affected behaviour on a more implicit response level. The findings suggest a correspondence in terms of both temporal and spatial characteristics, (i) for auditory MultiCS conditioning with different types and numbers of UCS in the N1m time-range (cf. Bröckelmann et al., 2011), (ii) of mechanisms underlying affective processing in the visual and the auditory system (cf. Bradley & Lang, 2000; Steinberg et al., 2012b) and (iii) for attention-modulated processing of both behaviourally significant emotional and non-emotional stimuli (e.g. Woldorff et al., 1993; Ferrari et al., 2008; Poghosyan & Ioannides, 2008; Bröckelmann et al., 2011).
