existed between fractional anisotropy (FA) values and training time. Consistent with our hypothesis, the white matter microstructure properties of both the dorsal and ventral pathways in expert table tennis players significantly differed from those in nonplayers. Specifically, FA values in the bilateral corticospinal tracts, which mainly connect brain regions in the dorsal sensorimotor system, were higher in experts than in nonplayers. Compared with nonplayers, expert players also had higher FA values in the left inferior longitudinal fasciculus and bilateral inferior occipitofrontal fasciculus of the ventral pathway, which are involved in higher-level cognitive processing, such as semantic processing or thinking. By contrast, no white matter region showed a higher FA value in nonplayers than in expert players, and no region was found with axial diffusivity difference between the groups. Additionally, radial diffusivity was lower in the left superior longitudinal fasciculus and bilateral inferior occipitofrontal fasciculus in experts than in nonplayers. Correlation analysis of the expert group showed significant positive correlations between training time and FA values in both the left superior longitudinal fasciculus in the ventral pathway and bilateral corticospinal tracts in the dorsal pathway. Taken together, these findings suggest that enhanced structural integrity of the white matter in both the dorsal and ventral pathways is associated with long-term, expert table tennis training. The observed structural plasticity is conducive to promoting cognitive processing of concrete sensorimotor and abstract information, which would enable expert players to excel at sports requiring a high level of strategy.

stronger incentive to defect. However, the results revealed a significantly higher cooperation level in LC. A plausible explanation is that the defection cost in form of punishment served as a norm reminder, but cost in form of tax lacked this function, implying that even defectors are not necessarily benefit maximizers. The results of Experiment 2 confirmed this explanation: compared with unpunished defectors, the punished ones manifested a higher level of norm activation. The bootstrap analysis showed that the norm activation completely mediated TPP and cooperation. Experiment 2 also found a spillover effect of TPP: the punished defectors still demonstrated a high cooperation in a new different game where the sanction was absent. Finally, Experiment 3 found another spillover effect of TPP: bystanders who did not experience the punishment in person but witnessed it showed a significantly higher cooperation in subsequent interactions. In conclusion, oftentimes, people defect simply because they are unaware of the existence of a certain norm, and activating people’s norms through TPP can significantly reduce their selfish behaviors. In addition to being an economic means to reduce defectors’ payoff, TPP serves as a norm reminder. The two spillover effects found in this study suggest that TPP as a means of norm activation may be more efficient than as an economic means because of its cost-effectiveness. These findings shed new light on the understanding of extensive cooperation among genetically unrelated individuals.

“The love of beauty is an essential part of all healthy human nature.” Aesthetic need is a high-level spiritual pursuit of human beings. In recent years, researchers have gradually paid more and more attention to the importance of beauty. Although researchers have carried out many aesthetic studies, most have focused on the study of static stimuli and not dynamic stimuli such as flying birds or fast trotting horses. Thus, research in cognitive experimental aesthetics and cognitive neuroaesthetics has not addressed the following questions: beautiful. In Experiment 2 we explored neural mechanisms that underlie aesthetic judgment of dynamic animal-stick figures and compared the neural mechanisms between the aesthetic judgments of dynamic animal-stick figures and static ones. 20 participants who did not participate in Experiment 1 were scanned while they performed aesthetic judgments on dynamic animal-stick figures and matched static animal-stick figures. Results revealed that regions of occipital lobe, frontal lobe, hippocampus, cingulate cortex, insula, orbital frontal cortex (OFC) and amygdala were commonly activated in the aesthetic judgments of both dynamic and static animal-stick figures. The neural networks involved in aesthetic judgments of dynamic animal-stick figures overlapped with those involved in aesthetic judgments of static animal-stick figures. Furthermore, compared to static animal-stick figures, stronger activations of lingual gyrus and middle temporal gyrus (MT/V5) were found in the aesthetic judgments of dynamic animal-stick figures. However, compared to dynamic animal-stick figures, no significant activations were found in beautiful judgments of static animal-stick figures. In summary, the present study indicated that the dynamic property of animal-stick figures affected aesthetic judgment and dynamic animal-stick figures were more beautiful than static ones.

We manipulated memory strength through two kinds of acquisition procedures on the day, varied the predictability of the unconditioned stimulus (US) occurrence after the conditioned Twenty-four hours later, a reminder containing a single PE was used to reactivate memories, which was followed by a stress task (Social Evaluate Cold Pressor test, SECPT) or not before extinction. After 24 hours, a test of spontaneous recovery and reinstatement was utilized to measure the return of fear in each condition. All participants were divided into three conditions: CS-Predictable US_no Stress Group, CS-Unpredictable US_no Stress Group and the CS-Unpredictable US_Stress Group. Skin conductance response (SCR) and fear-potentiated startle response (FPS) were used as measurements of conditioned fear. The results showed that there was a relatively stronger increase in fear response (SCR) from Day 1 to Day 2 in the CS-Unpredictable US condition than the CS-Predictable US condition, which may suggest a difference in memory strength between conditions. And for the weak fear memory (CS-predictable US), the reactivation that involved a single PE and was followed by extinction training prevented the spontaneous recovery, especially on the SCR measurement. On the other hand, in the enhanced memory condition (CS-unpredictable US), the extinguished memory returned in the memory test on the third day, which suggests a failure of memory destabilization. Furthermore, when the post-reactivation acute stress task was adopted in the enhanced memory condition, the return of fear further increased, compared with the no stress manipulation conditions. These results indicate that PE used to destabilize weak memories is insufficient to destabilize strong memories; and that post-reactivation acute stress cannot nullify this deficit which is due to boundary conditions (e.g., strength). We discuss possible interpretations of these results and the implications for the translation of retrieval-extinction to clinical practice.

Empathy to others’ pain is key to human social interaction and development. Previous studies suggest that pain empathy is influenced by numerous factors, including different characteristics of the observed target and the observer. Moreover, the relationship between an observer and the target also plays an important role. Self-construal, a personality trait, reflects the extent to which people consider themselves as connected to or separated from others. Recently, researchers have found temporal self-construal priming could modulate empathic neural responses to pain and change racial in-group bias measured in the neural response to pain. Unlike temporary, situational self-construal, the dispositional self-construal is a stable trait, the formation of which is influenced by long-term cultural experience. Previous ERP studies have found dispositional self-construal to modulate self-relevant processing more rapidly than temporal self-construal. Thus, the present study explores whether dispositional self-construal is related to empathic neural responses to others’ pain and whether in-group bias mediates such modulation. It has been shown that the temporal processing of empathy for pain consists of an early emotional sharing stage and a late cognitive evaluation stage. Accordingly, we assumed dispositional self-construal would correlate with either automatic emotional sharing or top-down controlled processes of empathy for pain. Twenty-seven participants study. participants the models the pictures selected from their fellow-townsman WeChat groups and other WeChat groups Next, we electroencephalography (EEG) while part in a word-priming paradigm, in which a word cue (“ingroup” or “outgroup”) was presented for 500 ms, indicating the identity of the model, followed by a picture of the model’s face touched either by painful or non-painful stimulation. Participants were instructed to judge whether the model in the picture was feeling pain by pressing a button using the left or right index fingers. After the EEG recording, participants rated the intensity of pain supposedly felt by the model as well as the degree of unpleasantness they felt when they saw each picture. Participants also completed the 24-item SCS on a seven-point scale to evaluate their interdependence and independence of self-construal. The ERP results showed a significant ingroup bias in the early N2 component. Painful stimuli elicited a greater negative shift relative to non-painful stimuli in response to ingroup faces. No such effect was observed on outgroup faces. The N2 component has previously been associated with automatic emotion sharing. A long latency empathic response was also observed at P3 over parietal electrodes.
