With the Covid-19 pandemic, many governments introduced nationwide lockdowns that disrupted people’s daily routines and promoted social isolation. We applied a longitudinal online survey to investigate the mid-term effects of the mandated restrictions on the perceived passage of time (PPT) and boredom during and after a strict lockdown in Germany. One week after the beginning of the lockdown in March 2020, respondents reported a slower PPT and increased boredom compared to the pre-pandemic level. However, in the course of the lockdown, PPT accelerated and boredom decreased again until August 2020. Then, in October 2020, when incidence rates sharply rose and new restrictions were introduced, we again observed a slight trend toward a slowing of PPT and an increase of boredom. Our data also show that as the pandemic progressed, respondents adjusted their predictions about the pandemic’s duration substantially upward. In sum, our findings suggest that respondents adapted to the pandemic situation and anticipated it as the new “normal”. Furthermore, we determined perceived boredom and the general emotional state to be predictive of PPT, while depressive symptoms played a minor role.

Personal space can be defined as a more or less concentric area around a person, into which intrusion causes arousal or discomfort (Hayduk, 1978). Preferred interpersonal distance (IPD) is the distance a person keeps from another to prevent intrusion of her or his personal space. Aside from obvious situational factors (e.g., the context of a crowded bus vs. an open field), personal space is strongly influenced by social cues (Ruggiero et al., 2017), social norms, and values (Iachini, Pagliaro, & Ruggiero, 2015; Leibman, 1970). Consequently, personality traits or disorders that change the perception or evaluation of such norms should also affect personal space regulation. We explored the effect of psychopathy in this context. It is characterized by persistent deviant social behavior and interpersonalemotional deficiencies (see, e.g., Hare, 2006). Not only do psychopaths tend to exploit others, they may also cause harm by undermining social norms. Recent discussions regarding psychopathy give rise to a conceptualization of psychopathy that does not limit the concept to clinical populations but includes subclinical and "successful" psychopaths (Patrick & Drislane, 2015). Thus, psychopathy is not limited to forensic samples, but can be studied in community samples as well (Boll & Gamer,

Violations of personal space are associated with discomfort. However, the exact function linking the magnitude of discomfort to interpersonal distance has not yet been specified. In this study, we explore whether interpersonal distance and discomfort are isotropic with respect to uncomfortably far or close distances. We also extend previous findings with regard to intrusions into personal space as well as maintenance of distances outside of personal space. We presented subjects with 15 interpersonal distances ranging from 40 to 250 cm and obtained verbal and joystick-based ratings of discomfort. Whereas discomfort rose immediately when personal space was entered, the gradient was less steep for distances that exceeded the comfort region of personal space. Thus, personal space is anisotropic with regard to experienced discomfort.

In the wake of the COVID-19 pandemic, it has been mandated to keep enlarged distances from others. We interviewed 136 German subjects over five weeks from the end of March to the end of April 2020 during the first wave of infections about their preferred interpersonal distance (IPD) before, during, and after the COVID-19 pandemic. In response to the pandemic, subjects adapted to distance requirements and preferred a larger IPD. This enlarged IPD was judged to partially persist after the pandemic crisis. People anticipated keeping more IPD to others even if there was no longer any risk of a SARS-CoV-2 infection. We also sampled two follow-up measurements, one in August, after the first wave of infections had been flattened, and one in October 2020, at the beginning of the second wave. Here, we observed that IPD varied with the incidence of SARS-CoV-2 within Germany. Overall, our data indicated that adaptation to distance requirements might happen asymmetrically. Preferred IPD rapidly adapted in response to distance requirements, but an enlargement of IPD may partially linger after the COVID-19 pandemic-crisis. We discuss our findings in light of proxemic theory and as an indicator for socio-cultural adaptation beyond the course of the pandemic.

Background Mandatory rules for social distancing to curb the SARS-CoV-2 pandemic require individuals to maintain a critical interpersonal distance above 1.5 m. However, this contradicts our natural preference, which is closer to 1 m for non-intimate encounters, for example, when asking a stranger for directions. Objective This review addresses how humans typically regulate interpersonal distances, in order to highlight the challenges of enforcing atypically large interpersonal distances. Method To understand the challenges posed by social distancing requirements, we integrate relevant contributions from visual perception, social perception, and human factors. Results To date, research on preferred interpersonal distances suggests that social distancing could induce discomfort, heighten arousal, and decrease social signaling in the short term. While the protracted effects of social distancing are unclear, we propose hypotheses on the mid- to long-term consequences of violating preferred norms of interpersonal distances. Conclusion We suggest that enforcing a physical distance of 1.5–2 m presents a serious challenge to behavioral norms. Application We address how notifications, architectural design, and visualizations could be effectively applied to promote interpersonal distance requirements.
