Intergroup contact in virtual reality
This study employed virtual reality (VR) to examine how avatar embodiment (self vs stranger), virtual human race (ingroup vs outgroup), and contact valence (positive vs negative) influence intergroup attitudes. US participants ( N = 262) assigned to avatars displaying a stranger’s face, rather than their own, showed greater acceptance of outgroup virtual humans. Perceived identifiability mediated the influence of avatar face on self-other overlap…
Entre la memoria y el exotismo
Este artículo analiza dos películas de la televisión pública alemana rodadas en Chile —Mein Herz in Chile (2008) y Die Briefe meiner Mutter (2014)— con el objetivo de examinar la imagen de Chile que ambas construyen y difunden. A partir de la imagología y la teoría poscolonial, se indaga cómo estas producciones articulan memoria histórica, exotismo y jerarquías culturales para configurar un relato visual en el que Chile se presenta como un territ…

Can Stereotype Threat and Lift Visual Messages Affect Subsequent Physical Activity? Evidence from a Controlled Experiment Using Accelerometers
380) were exposed to a stereotype threat, lift, or control condition image and then engaged in a running task. Accelerometers recorded forward-backward movement, upward-downward movement, and sideways balance. Stereotype threat exposure increased state anxiety relative to the control condition. In addition, forward-backward movement was linked to state anxiety and participants' sex. Moreover, women exposed to stereotype threat who experienced inc…
Virtual leaders
This study investigated how avatar customization activated leadership styles which may influence subsequent altruistic behavior. Participants (N = 222) engaged in a resource allocation task after customizing avatars that combined their physical self with the traits of democratic or authoritarian business leaders relative to a control condition. Authoritarian condition participants showed decreased altruism than those in the democratic condition. …
Can Avatar Appearance Influence Physical Activity? User-Avatar Similarity and Proteus Effects on Cardiac Frequency and Step Counts
This study combined user-avatar similarity and Proteus effect predictions to incentivize physical activity. 305 participants ran while wearing accelerometers and a heart rate monitor. They were randomly assigned to onscreen motion-capturing avatars displaying either participant or stranger faces dressed in sports or formal clothes. Participants assigned to avatars displaying their own face showed increased cardiac frequency compared with those ex…
The effects of avatar customization and virtual human mind perception
This study investigated how “teacher” avatar customization and exposure to “learner” virtual humans who display mind-affected participants’ behavior and emotions in a re-creation of Milgram’s obedience experiment. Female participants customized avatars that merged their physical self with hero, antihero, or villain archetypes and then interacted with a mindful or non-mindful virtual human; 82.8% of participants went above the maximum electric sho…
Face the Uncanny
228) examined how exposure to a talking head doppelganger created by an artificial intelligence (AI) program influenced affect-based trust toward AIs. Using a 3 (talking head featuring the participant's or a stranger's face, audio-only condition) by 2 (pro-AI pitch and anti-AI pitch playback) design, we uncovered that exposure to a talking head featuring the participant's face instead of a stranger's face increased uncanny valley perceptions. Fur…
A replication and expansion of the exposure effects of online model photos and social comparison goals on planned behaviors and self-efficacy to lose weight
This study replicated and expanded social comparison theory predictions in regard to how exposure to online models and explicit comparison goals affected planned behaviors and self-efficacy to lose weight in men and women. A 2 (models’ attractiveness: more attractive vs less attractive) × 2 (models’ weight status: lower vs higher) × 2 (explicit social comparison instructions: present vs absent) × 2 (gender: female vs male) factorial design was ad…
Mapping participatory planning in Havana
In 2019, Cuba approved a new political constitution that calls for deepening citizen participation to strengthen local governance. The emerging decentralization processes and the role of new actors in urban development open new possibilities for inclusive planning. While citizen participation is widely documented in the global South and under Western liberal democracy regimes, participatory urban planning in the context of Southern socialist citi…
Virtual Reality and Political Outgroup Contact
This study ( N = 217) explores the potential for virtual reality to decrease social distance toward outgroup members among women. Raising the salience of individuals' real physical identity through avatar customization and common ingroup identity manipulations was theorized to influence social distance. Participants who customized an avatar to resemble their real selves showed increased social distance. However, avatar customization also increase…
Examining Identity Shift Effects in Virtual Reality
Identity shift describes how individuals commit to self-presentations made in public computer-mediated contexts. This study attempts to expand identity shift effects to virtual reality. Participants were randomly assigned to present themselves as extraverted or introverted in pilot tested public or private virtual environments. The hypotheses and data analysis strategy were preregistered, and the study had sufficient a priori statistical power. T…
Game perspective-taking effects on willingness to help immigrants
This study replicated an experiment examining video game character perspective-taking effects on socio-political opinions with a sample of Spanish participants. Random assignment to play a game as an immigration inspector decreased intention and attitudes toward helping immigrants relative to baseline scores. These effects were observed while controlling for social dominance orientation or preference for inequality among social groups. The intent…
I Am What I See
This study examined how avatar body size (normal, obese) and opponent character body size (normal, obese) influenced physical activity while male participants played an exergame. Males operating normal weight avatars showed more physical activity than those using obese avatars. Perceived avatar and opponent character body-size differences moderated the effect of avatar appearance on physical activity. Participants showed decreased physical activi…
The Priming Effects of Virtual Environments on Interpersonal Perceptions and Behaviors
This study investigated how virtual environments prime subsequent interpersonal relations among unacquainted individuals. Participants met in a virtual library or a café. Individuals in the virtual library perceived greater self and partner formality compared to those in the café. In addition, more self-disclosure correlated with less formality only in the library, showing how revealing more about oneself goes against library norms. In contrast, …
The Cowl Makes the Monk
This study examined how avatars influence operators in stereotype-consistent ways. Participants controlled formally or glamorously dressed avatars, and then created stories. Half of the participants heard a comment about the likely role of the avatar based on its looks (e.g., professor, supermodel). An automated linguistic analysis uncovered that participants using formally dressed avatars referred more to education, books, and numbers. Conversel…

A Call to Educate, Participate, Invoke and Indict
This study analyzes the messages in hate group websites using a grounded theory approach. Through this process of interpretive inquiry we propose four prominent themes—educate, participate, invoke, and indict—that characterize the messages examined in 21 hate groups. These message themes speak to the: (a) education of members and external publics; (b) participation within the group and in the public realm; (c) invocation of divine calling and pri…
The Construction of Away Messages
Previous research suggests that "away messages" in instant messaging express informational and entertainment communicative goals while displaying a users' identity. This study investigated the extent to which these communicative goals are reflected in the language structure of away messages, by examining the speech acts performed through the production of 483 away messages crafted by 44 participants. The messages were also analyzed for the use of…
The Effects of Avatar Appearance in Virtual Worlds
In virtual worlds, users employ avatars to interact with their surroundings and with each other. However, while users exert influence on their avatar, their avatar can also exert influence on them. For instance, research has demonstrated that avatars can influence their users to be more negative, confident, aggressive, or intimate. In this paper, the ways through which subtle signals from an avatar's physical appearance can influence users and in…
