This experimental research explored background music\'s influence on the performance of numerical and spatial location working memory of extraverts and introverts. Sixty participants (30 extraverts and 30 introverts) were asked to complete numerical and spatial location working memory tests, under the conditions of background music and silence. Results showed a main negative effect of background music on the participants\' performance of spatial location working memory. A significant interaction effect between music and personality (extroversion and introversion) on this performance was also observed. It revealed that a more negative effect of music in introverts as compared with extroverts. In contrast, no main or interaction effect was observed for the performance of numerical working memory. According to the influence of music on working memory, introversion-extraversion personality factors of workers such as cashiers or drivers require consideration.

This study investigated whether forms of extraversion-introversion produced different depression-related outcomes before and during the COVID-19 pandemic.
One-way MANCOVAs were conducted to investigate the relationship between extraversion-introversion and depressive symptoms. These data were sourced from the NLSY97, consisting of 4846 individuals born between 1980 and 1984.
During pre-pandemic periods, high introversion increased the risk of depressive symptoms. During the pandemic, the risk for depressive symptoms was more equivalent, or less predominately high-introvert-based, among extraverted/low introverted and high introverted subjects.
Extraversion/low introversion was linked with increased depression, relative to high introversion, during the pandemic. The findings raise significant questions about how individuals with distinct personality traits may experience changes in their psychological well-being during challenging public health events.

Earth\'s known supercontinents are believed to have formed in vastly different ways, with two endmembers being introversion and extroversion. The former involves the closure of the internal oceans formed during the break-up of the previous supercontinent, whereas the latter involves the closure of the previous external superocean. However, it is unclear what caused such diverging behavior of supercontinent cycles that involved first-order interaction between subducting tectonic plates and the mantle. Here we address this question through 4D geodynamic modeling using realistic tectonic set-ups. Our results show that the strength of the oceanic lithosphere plays a critical role in determining the assembly path of a supercontinent. We found that high oceanic lithospheric strength leads to introversion assembly, whereas lower strength leads to extroversion assembly. A theoretically estimated reduction in oceanic crustal thickness, and thus its strength, during Earth\'s secular cooling indicates that introversion was only possible for the Precambrian time when the oceanic lithosphere was stronger, thus predicting the assembling of the next supercontinent Amasia through the closure of the Pacific Ocean instead of the Indian-Atlantic oceans. Our work provides a new understanding of the secular evolution of plate tectonics and geodynamics as the Earth cooled.

BACKGROUND: The main treatment methods for cancer include surgery, radiotherapy, chemotherapy, targeted drug therapy and so on. Patients often feel anger, anxiety, depression, and other negative psychological reactions in the process of treatment.
OBJECTIVE: To explore the effects of cognitive behavioral therapy on the personality characteristics of cancer patients.
METHODS: According to the matching design requirements, 150 cancer patients were divided into 3 groups based on sex, age, condition, and cultural background. Patients in the control group received conventional treatment. Patients in experimental group 1 received an intervention based on conventional treatment combined with cognitive behavioral therapy. Patients in experimental group 2 received family members\' participation in addition to the treatment given in experimental group 1. An Eysenck personality questionnaire was used to investigate all the patients before and after the intervention, and the scores for psychosis, introversion, neuroticism, and concealment degree were analyzed.
RESULTS: Compared with the control group, for experimental group 1 and experimental group 2 before and after the intervention, the four dimensions of mental quality, neuroticism, introversion and concealment degree all decreased, and the difference was statistically significant (P < 0.05). After the intervention, there were no obvious or statistically significant differences (P > 0.05) among the control group, experimental group 1, and experimental group 2 for two personality traits, psychoticism and neuroticism, both inside and outside degree and all four dimensions.
CONCLUSIONS: Simple cognitive behavioral therapy could not change the personality characteristics of cancer patients quickly, but the patients\' personality characteristics were significantly improved after treatment.

Freshmen were found to use social networking sites (SNS) as a useful medium to effectively adjust to college life, which hints at a tendency to resort to SNS for social compensation. However, the compensatory use of SNS is usually problematic.
This study explores why a subgroup of freshmen developed depressive symptoms while socially adjusting to college by investigating the antecedent role of introversion, the explanatory role of compensatory use of SNS, and the protective role of perceived family support. The study is among the first to point out the relevance of the compensatory use of SNS in explaining the indirect association between introversion and depression with a longitudinal design.
A 3-wave panel sample of freshmen (N=1137) is used to examine the moderated mediation model.
We found that introversion at Wave 1 positively predicted compensatory use of SNS at Wave 2 and subsequently increased depression at Wave 3 (unstandardized B=0.07, SE 0.02, P<.001, 95% CI 0.04-0.10; unstandardized B=0.09, SE 0.01, P<.001, 95% CI 0.06-0.12). The moderated mediation model further examined the buffering role of perceived family support within the link between introversion and compensatory SNS use (index=0.0031, SE 0.0015, 95% CI 0.0003-0.0062). Unexpectedly, we found that family support in Wave 1 decreased compensatory SNS use for less introverted freshmen in Wave 2 and further decreased depression in Wave 3.
Unexpectedly, our findings uncover an enhancing effect, rather than a buffering effect, of family support by embedding its effect within the relationship between introversion and compensatory SNS use. Appreciating the differences in the casual pathways for freshmen with different levels of introversion clarifies how SNS affect young adults\' lives.
