Praising others differently: neuroanatomical correlates to individual differences in trait gratitude and elevation

Consensus Paper: Cerebellum and Reward

Cerebellum is a key-structure for the modulation of motor, cognitive, social and affective functions, contributing to automatic behaviours through interactions with the cerebral cortex, basal ganglia and spinal cord. The predictive mechanisms used by the cerebellum cover not only sensorimotor functions but also reward-related tasks. Cerebellar circuits appear to encode temporal difference error and reward prediction error. From a chemical standpoint, cerebellar catecholamines modulate the rate of cerebellar-based cognitive learning, and mediate cerebellar contributions during complex behaviours. Reward processing and its associated emotions are tuned by the cerebellum which operates as a controller of adaptive homeostatic processes based on interoceptive and exteroceptive inputs. Lobules VI-VII/areas of the vermis are candidate regions for the cortico-subcortical signaling pathways associated with loss aversion and reward sensitivity, together with other nodes of the limbic circuitry. There is growing evidence that the cerebellum works as a hub of regional dysconnectivity across all mood states and that mental disorders involve the cerebellar circuitry, including mood and addiction disorders, and impaired eating behaviors where the cerebellum might be involved in longer time scales of prediction as compared to motor operations. Cerebellar patients exhibit aberrant social behaviour, showing aberrant impulsivity/compulsivity. The cerebellum is a master-piece of reward mechanisms, together with the striatum, ventral tegmental area (VTA) and prefrontal cortex (PFC). Critically, studies on reward processing reinforce our view that a fundamental role of the cerebellum is to construct internal models, perform predictions on the impact of future behaviour and compare what is predicted and what actually occurs.

Impact of Moral Elevation on College Students' Sense of Meaning of Life: The Mediating Roles of Gratitude and Perceived Social Support

Purpose

The current study examined the association between moral elevation and college students' sense of meaning of life, along with the potential mediating effects of gratitude and perceived social support on this relationship.

Methods

Using the convenience sampling method, the Moral Elevation Scale, the Sense of Meaning of Life Questionnaire, the Gratitude Questionnaire, and the Multidimensional Scale of Perceived Social Support were used to conduct questionnaire surveys on 1088 college students (Mage=19.59 years, SD=1.46). SPSS25.0 data statistics software was used to analyze the data, and the PROCESS macro for SPSS was used to conduct the mediation effect test.

Results

(1) Moral elevation was significantly and positively associated with college students' sense of meaning of life (β = 0.43,p < 0.001). (2) Both gratitude and perceived social support partially mediated the relation between moral elevation and sense of meaning of life. The indirect effect of moral elevation on sense of meaning of life via gratitude was 0.11 (95% CI = [0.0709, 0.1453]), and the mediating effect accounted for 52.71%. The indirect effect of moral elevation on sense of meaning of life via perceived social support was 0.06 (95% CI = [0.0385, 0.0863]), and the mediating effect accounted for 29.41%. (3) Gratitude and perceived social support sequentially mediated the association between moral elevation and sense of meaning of life, the indirect effect through gratitude and perceived social support was 0.04 (95% CI = [0.0237, 0.0512]) and accounted for 17.88%.

Conclusion

This study revealed the chain mediating roles of gratitude and perceived social support in the relation between moral elevation and sense of meaning of life for Chinese college students, which is of great theoretical and practical significance for the formation of a positive sense of meaning of life and the cultivation of moral elevation among college students.

Comparing gratitude and pride: evidence from brain and behavior

Gratitude and pride are both positive emotions. Yet gratitude motivates people to help others and build up relationships, whereas pride motivates people to pursue achievements and build on self-esteem. Although these social outcomes are crucial for humans to be evolutionarily adaptive, no study so far has systematically compared gratitude and pride to understand why and how they can motivate humans differently. In this review, we compared gratitude and pride from their etymologies, cognitive prerequisites, motivational functions, and brain regions involved. By integrating the evidence from brain and behavior, we suggest that gratitude and pride share a common reward basis, yet gratitude is more related to theory of mind, while pride is more related to self-referential processing. Moreover, we proposed a cognitive neuroscientific model to explain the dynamics in gratitude and pride under a reinforcement learning framework.
