Abstract： The ultimatum game is commonly used to examine fairness-related economic decision making, and the trade-off between fairness preferences and self-interest is assumed to determine whether individuals reject or accept unfair offers. With respect to the dual-system theory, there are controversial understandings on whether fairness preferences result from the automatic response in System 1 or the deliberation processes in System2. Our study discussed such controversy from three aspects of this theory, including theoretical hypotheses, influential factors, and neural mechanisms. The automatic negative reciprocity hypothesis and the social heuristics hypothesis contend that fairness preferences are automatic, whereas the controlled-processing hypothesis contends that fairness preferences are products of deliberation process that suppresses self-interest motivation. System 1 identifies and evaluates fairness via anterior insula, amygdala, and ventromedial prefrontal cortex; while System 2 reassesses and adjusts System 1 to make the final decision via dorsal anterior cingulate cortex, ventrolateral PFC, dorsomedial PFC, and left dorsolateral PFC. Individual differences and experimental task characteristics may affect individuals’ automatic responses in System 1. Future research need to further improve the experimental paradigm; explore the moderators within the dual system and its neural network.

Abstract： With the service industry growing rapidly to contribute to about 60% of the world’s GDP, improving customer service quality with high service performance (in-role performance and proactive customer service performance) is critical for service organizational development. Previous research has linked employee service performance with a variety of potential antecedents, such as individual difference factors and organizational factors from resource, identification, and motivation perspectives. Surprisingly, we know little about how customer positive behaviors (e.g., customer-initiated support) might affect employees’ service performance. This is a critical gap to fill because customers have substantial power and impact on front-line service employees through frequent direct interactions with them during service delivery. Drawing on the self-verification theory, the present study aimed to examine the effect of customer-initiated support on employee service performance (in-role performance and proactive customer service performance) and explore the mediating role of organization-based self-esteem and the moderating roles of promotion focus and internal locus of control. We collected three-wave time-lagged data from 652 nurses nested within 139 department supervisors. In the first-wave survey (T1), employees reported perceived customer-initiated support, their promotion focus, internal locus of control, proactive personality, and demographic variables. In the second-wave survey (T2), employees who had completed first wave questionnaires were asked to rate their organizational-based self-esteem. In the third wave survey (T3), employees’ supervisors were asked to report the employees’ service performance, including in-role performance and proactive customer service performance. Results from multilevel modeling analysis showed that: (1) customer-initiated support was positively related to employee organization-based self-esteem; (2) organization-based self-esteem was positively related to employee in-role performance and proactive customer service performance; (3) employee organization-based self-esteem mediated the relation between customer-initiated support and employee in-role performance and proactive customer service performance; (4) promotion focus strengthened the positive relationship between customer-initiated support and organization-based self-esteem, such that the positive relationship between customer-initiated support and organization-based self-esteem is stronger for employees with higher promotion focus; (5) internal locus of control weakened the relationship between customer-initiated support and organization-based self-esteem, such that the positive relationship between customer-initiated support and organization-based self-esteem is weaker for employees with higher internal locus of control. Our findings contribute to literature in several ways. First, we contribute to the service performance literature by identifying customer-initiated support as a potential antecedent. Second, this study uncovers the potential mechanism of customer-initiated support’s impact on employee service performance from the self- verification perspective, which broadens previous research from resources, identification, and motivation perspectives. Third, this study confirms the moderating roles of promotion focus and internal locus of control, which contributes to the understanding of under what conditions the effect of customer-initiated support will be stronger.

Abstract： Hypnosis is an effective psychological technology in respiratory motion control. In this study, functional magnetic imaging was applied to an intra-subject (n＝13) design hypnosis experiment guided by hypnotists to analyze the respiratory motion control and neural activity in hypnosis. As a result, increased brain activities were observed in visual cortex, sensorimotor cortex, posterior cingulate cortex and middle temporal gyrus, and decreased in dorsolateral prefrontal cortex, cerebellum posterior lobe and supramarginal gyrus. Moreover, compared with normal state, enhanced correlation of brain activities (normal state, r＝0.64; hypnosis state, r＝0.80) was observed within large-scale resting-state networks. Increased connectivity between sensorimotor cortex and visual cortex in hypnosis was also observed, which implies their critical roles in neural mechanisms of hypnosis for respiration control and involvement of cognitive and perceptual processing therein. This study provides new insights for hypnosis study in psychology and cognitive neuroscience.
