“…Then, the nine-point SAM scale ranging from 1 ( unpleasant facial expression ) to 9 ( pleasant facial expression ) was presented for 3 seconds, at which time the participants rated the emotional valence of the images by responding with the keyboard, which was considered one trial. We designed the study protocol based on previous studies (Aguado et al, 2019; Cheng et al, 2017; Hill et al, 2019). Completion of a block of trials required 4–5 minutes.…”

“…In contrast, there was no significant difference in N1, P2, and N2 amplitudes for happy moods. Hill et al (2019) examined the effect of mood (happy/neutral/fear) induced by movies on emotional evaluation by measuring the LPP in response to unpleasant images. They demonstrated that the LPP amplitude increased significantly more for unpleasant images than for neutral images when participants were in neutral and fearful moods but not in happy moods.…”

“…Studies examining the effects of mood on cognitive processes have used different stimuli to induce mood, including language (Polivy & Doyle, 1980), autobiographical memory recall (Pastötter et al, 2013), music (Cheng et al, 2017), images (Hunter et al, 2011; Moriya & Nittono, 2011), and movies (Hill et al, 2019; Schmid & Mast, 2010). Also, some mood induction methods require semantic processing, which might influence the cognitive processing of subsequent stimuli (Wang et al, 2016).…”

“…The LPP amplitude has increased more for emotional than for neutral images (Schupp et al, 2000) and has decreased for stimuli that have an emotional valence that is inconsistent with the mood (Hill et al, 2019). Therefore, we expected that the LPP amplitudes would decrease for images that had an incongruent emotional valence with the induced mood but would not decrease for images with a congruent emotional valence.…”

Tastes affect the body and our emotions. We used tasteless, sweet, and bitter stimuli to induce participants’ moods, and we examined the effect of mood on an emotional evaluation of pleasant, neutral, and unpleasant images using event-related potentials, N2, N400, and late positive potential (LPP), which reflect emotional evaluation in the brain. The results indicated that mood valence was most positive for sweetness and most negative for bitterness. Moreover, there was no significant mood effect on subjective valence ratings of emotional images. Furthermore, the N2 amplitude, which is related to the early semantic processing of preceding stimuli, was unaffected by the taste induced mood. In contrast, we found that the N400 amplitude, which is related to the mismatch of emotional valence between stimuli, increased significantly for unpleasant images when participants were in a positive rather than negative mood state. Also, the LPP amplitude, which is related to the emotional valence of images, showed only the main effect of the images’ emotional valence. The N2’s results suggest that the early semantic processing of taste stimuli might have had a negligible impact on emotional evaluation because taste stimuli minimize semantic processing that accompanies mood induction. In contrast, the N400 reflected the effects of the induced mood, and the LPP reflected the impact of the valence of emotional images. The use of taste stimuli to induce mood revealed different brain processing of taste-induced mood effects on emotional evaluation, including N2’s involvement in semantic processing, N400’s involvement in matching emotions between mood and stimuli, and LPP’s involvement in subjective evaluations of stimuli.

“…According to previous studies ( Larson et al, 2014 ; Hill et al, 2019 ) and the visual inspection of grand-averaged waveforms and scalp topographies in the present study, the P2, N2, N450, frontal LPP, and the parietal LPP (analyzed separately at early and middle latency ranges) were analyzed. The peak amplitudes of the P2 in the time window of 150–200 ms, N2 in the time window of 190–350 ms, and the mean amplitudes of the N450 in the time window of 400–600 ms and frontal LPP in the time window of 700–900 ms were extracted at electrodes at the frontal and frontal-central areas (i.e., F3, Fz, F4, FC3, FCz, and FC4).…”

Effects of Core Disgust and Moral Disgust on Moral Judgment: An Event-Related Potential Study

et al. 2022

Core disgust is elicited by physical or chemical stimuli, while moral disgust is evoked by abstract violations of moral norms. Although previous studies have pointed out these two types of disgust can affect behavior and spatial dimensions of moral judgment, less is known about how moral and core disgust affect the temporal neural processing of moral judgment. In addition, whether moral and core disgust are only related to purity-based moral judgment or all kinds of moral judgment is still controversial. This study aimed to explore how core and moral disgust affect the neural processing of purity-based moral judgment by using affective priming and moral judgment tasks. The behavioral results showed that the severity of moral violation of non-purity ones is higher than purity ones. The event-related potentials (ERP) results mainly revealed that earlier P2 and N2 components, which represent the automatic moral processes, can differentiate neutral and two types of disgust rather than differentiating moral domain, while the later N450, frontal, and parietal LPP components, which represent the conflict detection and, later, cognitive processing can differentiate the purity and non-purity ones rather than differentiating priming type. Moreover, core and moral disgust priming mainly differed in the purity-based moral processing indexed by parietal LPP. Our findings confirmed that the disgusting effect on moral judgments can be explained within the framework of dual-process and social intuitionist models, suggesting that emotions, including core and moral disgust, played an essential role in the automatic intuition process. The later parietal LPP results strongly supported that core disgust only affected the purity-based moral judgment, fitting the primary purity hypothesis well. We show how these theories can provide novel insights into the temporal mechanisms of moral judgment.
