Interpersonal Distance in the SARS-CoV-2 Crisis
2020
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 pr…
Adapting to the pandemic: longitudinal effects of social restrictions on time perception and boredom during the Covid-19 pandemic in Germany
2022
AbstractWith 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 int…
Interpersonal Distance Regulation and Approach-Avoidance Reactions Are Altered in Psychopathy
2019
In this study, we examined the impact of psychopathy on approach-avoidance reactions and interpersonal distance (IPD) in response to social cues. We selected a student sample and measured psychopathy via self-report. Participants were immersed in a virtual environment in which a virtual person displayed either angry or happy facial expressions. In the first experiment, participants had to walk toward the virtual person until a comfortable IPD had been reached. In the second experiment, participants had to push or pull a joystick in response to the facial expression of the virtual person. Our results suggest that psychopathy does not change average IPD but does impair its regulation. That i…
Body image avoidance affects interpersonal distance perception: A virtual environment experiment.
2019
OBJECTIVE Eating disorders have a considerable influence on social contacts. The avoidance towards the own body may result in the avoidance of others. Previous research has found a preference for larger interaction distances in individuals with eating disorders (ED) as compared to control participants (CG). We aimed to replicate these findings and to investigate whether the body weight of the interactant moderates the effect. METHOD We recruited a female sample with mixed ED subtypes (n = 21) and a female CG (n = 28). Participants were immersed in a virtual environment and engaged in a number of fictitious social interactions. They approached a virtual person until a comfortable distance fo…
Psychopathy and the Regulation of Interpersonal Distance
2018
Psychopathic traits are often associated with interpersonal and affective deficits. This study examined the impact of psychopathy on judgments of comfortable egocentric interpersonal distance (Experiment 1) and exocentric interpersonal distance (Experiment 2). We selected a student sample and measured psychopathy via self-report. To study spatial behavior under highly controlled conditions, these participants were immersed in a virtual environment. In Experiment 1, they approached a virtual person with angry or happy facial expression until a comfortable distance for conversation was reached. In Experiment 2, participants adjusted a comfortable distance between two avatars. Our results sug…
Test–Retest Reliability and Temporal Agreement of Direct and Indirect Sexual Interest Measures
2020
The Explicit and Implicit Sexual Interest Profile (EISIP) is a multimethod measure of sexual interest in children and adults. It combines indirect latency-based measures such as the Implicit Association Test (IAT), Viewing Time (VT), and explicit self-report measures. This study examined test–retest reliability and absolute temporal agreement of the EISIP over a 2-week interval in persons who were convicted of sexual offenses against children ( n = 33) and nonoffending controls ( n = 48). Test–retest reliability of the aggregated EISIP measures was high across the whole sample ( rtt = .90, intraclass correlation coefficient [ICC] = .90) with the IAT yielding the lowest retest correlations …
Cognitive performance and emotion are indifferent to ambient color
2017
Folklore has it that ambient color has the power to relax or arouse the observer and enhance performance when executing cognitive tasks. We picked a number of commercially available colors that allegedly have the power to alter cognitive performance and the emotional state, and exposed subjects to them while solving a battery of cognitive tasks. The colors were “Cool Down Pink”, which is said to produce relaxing effects and reduce effort, “Energy Red”, allegedly enhancing performance via increased arousal, “Relaxing Blue”, which is said to enhance attention and concentration, as well as white as a control. In a between-subjects design, a total of 170 high school students carried out five ta…
The shape of personal space.
2019
The notion of a personal space surrounding one's ego-center is time-honored. However, few attempts have been made to measure the shape of this space. With increasing use of virtual environments, the question has arisen if real-world aspects, such as gender-effects or the shape of personal space, translate to virtual setups. We conducted two experiments, one with real people matched according to body height and level of acquaintance in a large laboratory setting, and one where subjects faced a virtual character, likewise matched to their body height. The first experiment also used a mannequin in place of the second human observer. The second experiment additionally manipulated the perspectiv…
The anisotropy of personal space.
2019
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…
