Horizontal Spatial Metaphors for Morality: A Cross-Cultural Study of Han Chinese Students and Ethnic Minority Hui Students in China

Metaphor is a bridge for understanding abstract concepts (the target domain) from concrete concepts (the source domain). This study, with two experiments, aimed to investigate the cultural differences of the horizontal spatial metaphors for morality between two groups of students: Han Chinese, the ethnic majority, and Hui Chinese, an ethnic minority in China. Experiment 1 adopted a spatial Stroop task. It showed that neither Hui nor Han students exhibited horizontal spatial metaphors for morality. Experiment 2 adopted a modified implicit association test paradigm to enhance the association between the moral concepts and the horizontal spatial positions. In Experiment 2, we found horizontal spatial metaphors for morality in Hui students, but not in Han students. These results indicated that the differences of horizontal spatial metaphors between Hui and Han participants were influenced by the different cultures they live in. Moreover, this study also found that the association between the source domain and the target domain was an important factor for metaphor formations

Neuroticism Modulates the Functional Connectivity From Amygdala to Frontal Networks in Females When Avoiding Emotional Negative Pictures

Amygdala activity was previously found to correlate with neuroticism as an effect of valence, but so far few studies have focused on motivational context. The network subserving altered amygdala activity has not yet been investigated although some studies showed strong effective connections with prefrontal cortex (PFC). The goal of this study was to test the modulatory role of neuroticism on the functional connectivity (FC) between amygdala and other brain regions, especially PFC, during emotion processing from motivational direction. We applied an emotional picture viewing paradigm with different motivational directions (approaching and avoiding) in a large participant sample. The results showed that neuroticism predicted the amount of amygdala FC to dorsomedial PFC (dmPFC) and middle cingulate cortex (MCC). Increased FC during negative vs. positive pictures was found primarily in low neuroticism subjects, especially during the avoid condition. This valence and motivation dependent connectivity increase were disrupted for high neurotic participants. No effect of neuroticism was found for the approach condition. We showed that neuroticism, especially in the context of passive affect regulation, may have impaired connectivity between amygdala and putative regulatory cortical networks

A New Standardized Emotional Film Database for Asian Culture

Researchers interested in emotions have endeavored to elicit emotional responses in the laboratory and have determined that films were one of the most effective ways to elicit emotions. The present study presented the development of a new standardized emotional film database for Asian culture. There were eight kinds of emotion: fear, disgust, anger, sadness, neutrality, surprise, amusement, and pleasure. Each kind included eight film clips, and a total of 64 emotional films were viewed by 110 participants. We analyzed both the subjective experience (valence, arousal, motivation, and dominance) and physiological response (heart rate and respiration rate) to the presentation of each film. The results of the subjective ratings indicated that our set of 64 films successfully elicited the target emotions. Heart rate declined while watching high-arousal films compared to neutral ones. Films that expressed amusement elicited the lowest respiration rate, whereas fear elicited the highest. The amount and category of emotional films in this database were considerable. This database may help researchers choose applicable emotional films for study according to their own purposes and help in studies of cultural differences in emotion
