Previous studies have suggested that attention plays an important role in the modulation of emotional evaluation. For example, the increase in positive affect toward repeatedly presented stimuli, called the mere exposure effect, is more likely to occur for attended stimuli than for unattended stimuli (Yagi et al., 2009; Huang and Hsieh, 2013). Furthermore, attention also plays an important role in evaluative conditioning where neural stimuli (conditioned stimuli), paired with affective stimuli (unconditioned stimuli), acquire the affective valence of the unconditioned stimuli. For example, distracting attention from conditioned and unconditioned stimuli disrupted the formation of conditioned affective valence (Field and Moore, 2012). In addition, distracting attention from the contingency between the conditioned and unconditioned stimuli also disrupted the effect (Kattner, 2012). Given that attention plays an important role in the acquisition of emotional value, emotional devaluation through response inhibition would occur more strongly for attended stimuli than it would for unattended stimuli.
