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 b...
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 experim...
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 finding...
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...
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...
In medicine, patients can obtain real benefits from a sham treatment. These benefits are known as the placebo effect. We report two experiments (Experiment I: N=369; Experiment II: N=100) demonstrating a placebo effect in adaptive interfaces. Participants were asked to solve word puzzles while being supported by no system or an adaptive AI interfac...
Fatalities with semi-automated vehicles typically occur when users are engaged in non-driving related tasks (NDRTs) that compromise their situational awareness (SA). This work developed a tactile display for on-body notification to support situational awareness, thus enabling users to recognize vehicle automation failures and intervene if necessary...
Virtual reality is increasingly used for tasks such as work and education. Thus, rendering scenarios that do not interfere with such goals and deplete user experience are becoming progressively more relevant. We present a physiologically adaptive system that optimizes the virtual environment based on physiological arousal, i.e., electrodermal activ...
Modern games make creative use of First-and Third-person perspectives (FPP and TPP) to allow the player to explore virtual worlds. Traditionally, FPP and TPP perspectives are seen as distinct concepts. Yet, Virtual Reality (VR) allows for flexibility in choosing perspectives. We introduce the notion of a perspective continuum in VR, which is techni...

Augmented Reality (AR) embeds virtual content in physical spaces, including virtual agents that are known to exert a social presence on users. Existing design guidelines for AR rarely consider the social implications of an agent's personal space (PS) and that it can impact user behavior and arousal. We report an experiment (N=54) where participants...

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....
In this paper, we investigate how mismatches between biological gender and avatar gender affect interpersonal distance (IPD) in virtual reality (VR). An increasing number of VR experiences and online platforms like Rec Room and VRChat allow users to assume other genders through customized avatars. While the effects of acquaintanceship and gender ha...
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 th...
When approaching another user in social VR, there comes the point where we start to feel uncomfortable and intruded upon. Therefore, users maintain a personal space that is kept clear from others, much like in the real world. Although many determinants on the size of personal space have been identified, the process of maintaining and constructing a...
The Explicit and Implicit Sexual Interest Profile (EISIP; Banse, Schmidt, & Clarbour, 2010) 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...
People visit public places with different intentions and motivations. While some explore it carefully, others may just want to pass or are otherwise engaged. We investigate how to exploit the inattentional blindness (IB) of indirect users in the design of public interfaces to apply to such diverse needs. Beginning with a structured literature study...

Zusammenfassung
Das Selbstregulationsmodell sexueller Rückfälligkeit („self-regulation model of the relapse process“, SRM) stellt eine Theorie zur Ätiologie sexueller Delinquenz und Rückfälligkeit dar, bei der sexuell motivierte Straftaten und Täter unterschiedlichen Rückfallpfaden und Entscheidungswegen zugeordnet werden, von denen aus wiederum au...
How does sexual attraction alter social interaction behavior? We examined the influence of sexual orientation on locomotor approach-avoidance behavior and interpersonal distance. We immersed androphilic and gynophilic male subjects into a virtual environment and presented various male and female virtual persons. In the first experiment, subjects to...
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 an...
Current theories view impulsivity as an important factor in the explanation of sexual
offending. While impulsivity itself is a multidimensional construct, response inhibition and
impulsive decision-making are two frequently discussed subcomponents. Impulsivity in
sexual offenders could be triggered by sexual cues with high emotional significance. T...
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. Th...
It is still unclear why psychopathic individuals might prefer shorter interpersonal distance (IPD). Therefore, we investigated whether psychopathy effects on IPD are modulated by facial expression and eogcentric vs. exocentric views.
Die Zahlreichen Übergriffe auf Frauen in der Silvesternacht in Köln führten zu einer aufgeregten Debatte. Die empirische Analyse der Strafanzeigen kann helfen, diese Debatte zu versachlichen.
Previous studies reported the perceived height of interior spaces to increase with increasing ceiling lightness. These experiments used verbal estimates of ceiling height, e. g., in centimeters, which might be influenced by cognitive processes. In the present study, we used a height matching task based on comparisons of a given interior space to a...

My aim is to measure approach and avoidance behavior within ecologically valid scenarios. Therefore, I implemented the Approach-Avoidance Task in virtual reality.
Most studies in the domain of proxemics focus on the size of personal space. The aim of this project is to investigate other properties of personal space such as the shape, the relation to discomfort etc.
It is still unclear why psychopathic individuals might prefer shorter interpersonal distance. In this project we investigate the effect of psychopathy on the regulation of interpersonal distance in response to different facial expressions. This is done in a virtual reality setting to allow for a high degree of experimental control while maintaining external validity.
