Within the solitude literature, two discrete constructs reflect different perspectives on how time spent alone is motivated. Self-determined motivation for solitude reflects wanting time alone to find enjoyment and gain meaningful benefits from it, whereas preference for solitude concerns wanting time for oneself over others’ company regardless of reasons for why time alone is wanted. We investigated two personality characteristics: introversion from Big-Five personality theory and dispositional autonomy from self-determination theory. In two diary studies university students completed personality measures and reported about their experiences with time spent alone over a period of seven days. Across both studies, contrary to popular belief that introverts spend time alone because they enjoy it, results showed no evidence that introversion is predictive of either preference or motivation for solitude. Dispositional autonomy–the tendency to regulate from a place of self-congruence, interest, and lack of pressure–consistently predicted self-determined motivation for solitude but was unrelated to preference for solitude. These findings provided evidence supporting the link between valuing time spent alone with individual differences in the capacity to self-regulate in choiceful and authentic way.

People are exposed to persuasive communication across many different contexts: Governments, companies, and political parties use persuasive appeals to encourage people to eat healthier, purchase a particular product, or vote for a specific candidate. Laboratory studies show that such persuasive appeals are more effective in influencing behavior when they are tailored to individuals’ unique psychological characteristics. However, the investigation of large-scale psychological persuasion in the real world has been hindered by the questionnaire-based nature of psychological assessment. Recent research, however, shows that people’s psychological characteristics can be accurately predicted from their digital footprints, such as their Facebook Likes or Tweets. Capitalizing on this form of psychological assessment from digital footprints, we test the effects of psychological persuasion on people’s actual behavior in an ecologically valid setting. In three field experiments that reached over 3.5 million individuals with psychologically tailored advertising, we find that matching the content of persuasive appeals to individuals’ psychological characteristics significantly altered their behavior as measured by clicks and purchases. Persuasive appeals that were matched to people’s extraversion or openness-to-experience level resulted in up to 40% more clicks and up to 50% more purchases than their mismatching or unpersonalized counterparts. Our findings suggest that the application of psychological targeting makes it possible to influence the behavior of large groups of people by tailoring persuasive appeals to the psychological needs of the target audiences. We discuss both the potential benefits of this method for helping individuals make better decisions and the potential pitfalls related to manipulation and privacy.

The quantum-phase-field concept of matter is revisited with special emphasis on the introverted view of space. Extroverted space surrounds physical objects, while introverted space lies in between physical objects. Space between objects leads to a network structure of matter: a network in which one-dimensional spaces connect individual particles.

Purpose: To examine the proposal that introversion predictably influences extralaryngeal and vocal behavior in vocally healthy individuals compared with individuals with extraversion and whether differences are of a nature that may support a risk hypothesis for primary muscle tension dysphonia. Method: Fifty-four vocally healthy female adults between the ages of 18 and 35 years were divided into 2 groups: introversion (n = 27) and extraversion (n = 27). All participants completed a psychological stress reactivity experiment. Before, during, and after the stressor (public speaking), participants were assessed on extralaryngeal muscle activity (surface electromyography: submental, infrahyoid; control site: tibialis anterior), perceived vocal effort, and vocal acoustics (fundamental frequency and intensity). Results: Participants in the introversion group exhibited significantly greater infrahyoid muscle activity throughout the protocol and during perceived stress than participants in the extraversion group. For both groups, perceived vocal effort significantly increased during stress, and acoustic measures significantly decreased. Infrahyoid muscle activity during the stress phase was significantly correlated with introversion and Voice Handicap Index scores but not with vocal effort scores. Conclusions: The data provided evidence of distinct differences in extralaryngeal behavior between introverts and extraverts. The findings are consistent with the trait theory of voice disorders (Roy & Bless, 2000).

\"The Awakened Introvert \"shows readers how to tap into their introvert strengths and \"awaken\" their potential using mindfulness meditations and cognitive behavioral techniques. Introverts will also learn to minimize weaknesses--such as a tendency toward worry and rumination--and discover new skills for recharging in between social encounters.

The World Health Organization considers coronavirus disease (COVID-19) to be a public emergency threatening global health. During the crisis, the public's need for web-based information and communication is a subject of focus. Digital inequality research has shown that internet access is not evenly distributed among the general population. The aim of this study was to provide a timely understanding of how different people use the internet to meet their information and communication needs and the outcomes they gain from their internet use in relation to the COVID-19 pandemic. We also sought to reveal the extent to which gender, age, personality, health, literacy, education, economic and social resources, internet attitude, material access, internet access, and internet skills remain important factors in obtaining internet outcomes after people engage in the corresponding uses. We used a web-based survey to draw upon a sample collected in the Netherlands. We obtained a dataset with 1733 respondents older than 18 years. Men are more likely to engage in COVID-19-related communication uses. Age is positively related to COVID-19-related information uses and negatively related to information and communication outcomes. Agreeableness is negatively related to both outcomes and to information uses. Neuroticism is positively related to both uses and to communication outcomes. Conscientiousness is not related to any of the uses or outcomes. Introversion is negatively related to communication outcomes. Finally, openness relates positively to all information uses and to both outcomes. Physical health has negative relationships with both outcomes. Health perception contributes positively to information uses and both outcomes. Traditional literacy has a positive relationship with information uses and both outcomes. Education has a positive relationship with information and communication uses. Economic and social resources played no roles. Internet attitude is positively related to information uses and outcomes but negatively related to communication uses and outcomes. Material access and internet access contributed to all uses and outcomes. Finally, several of the indicators and outcomes became insignificant after accounting for engagement in internet uses. Digital inequality is a major concern among national and international scholars and policy makers. This contribution aimed to provide a broader understanding in the case of a major health pandemic by using the ongoing COVID-19 crisis as a context for empirical work. Several groups of people were identified as vulnerable, such as older people, less educated people, and people with physical health problems, low literacy levels, or low levels of internet skills. Generally, people who are already relatively advantaged are more likely to use the information and communication opportunities provided by the internet to their benefit in a health pandemic, while less advantaged individuals are less likely to benefit. Therefore, the COVID-19 crisis is also enforcing existing inequalities.
