The effects of embodying wildlife in virtual reality on conservation behaviors.

Efforts to mitigate environmental threats are often inversely related to the magnitude of casualty, human or otherwise. This "compassion fade" can be explained, in part, by differential processing of large- versus small-scale threats: it is difficult to form empathic connections with unfamiliar masses versus singular victims. Despite robust findings, little is known about how non-human casualty is processed, and what strategies override this bias. Across four experiments, we show how embodying threatened megafauna-Loggerhead sea turtles (Caretta Caretta)-using virtual reality can offset and reverse compassion fade. After observing compassion fade during exposure to non-human casualty in virtual reality (Study 1; N = 60), we then tested a custom virtual reality simulation designed to facilitate body transfer with a threatened Loggerhead sea turtle (Study 2; N = 98). Afterwards, a field experiment (Study 3; N = 90) testing the simulation with varied number of victims showed body transfer offset compassion fade. Lastly, a fourth study (N = 25) found that charitable giving among users embodying threatened wildlife was highest when exposed to one versus several victims, though this effect was reversed if victims were of a different species. The findings demonstrate how animal embodiment in virtual reality alters processing of environmental threats and non-human casualty, thereby influencing conservation outcomes.

Customizing Your Demons: Anxiety Reduction via Anthropomorphizing and Destroying an "Anxiety Avatar".

Character customization is a prominent feature in digital games, affording users the ability to tailor one's virtual self-representation (avatar) to match aspects of their actual or ideal self, influencing psychological well-being. The mental health implications of character customization can be partially explained by self-discrepancy theory, which argues that achieving congruence with one's avatar reduces cognitive dissonance. However, the role of undesirable self-concepts such as mental health ailments have largely been overlooked in this context despite forming part of one's identity. In theory, customization of an avatar representing undesirable self-concepts presents a self-regulatory paradox: individuals desire to reduce discrepancies with a self-representation, yet they also desire to enlarge discrepancies with a disliked-self. To reconcile this, two experiments explored the psychological implications of imbuing avatars with undesirable self-concepts. In Study 1 (N = 90), participants customized an avatar to represent anxiety within themselves (i.e., an anxiety avatar). Customization significantly reduced state anxiety compared to a control group, supporting the proposed discrepancy-reduction mechanism. Study 2 (N = 122) employed a 2 (customization: yes, no) × 2 (destruction: yes, no) between-subjects design, with participants either destroying or observing an anxiety avatar. Destruction of customized anxiety avatars resulted in the largest reduction in anxiety among all conditions, supporting the proposed discrepancy-enlargement mechanism. Theoretical and practical implications for the use of avatar-based e-mental health interventions are discussed.

Delivering health information via podcast or web: media effects on psychosocial and physiological responses.

This study explored differences in psychosocial and physiological variables in response to being presented with information on weight loss through either reading text on a website or listening to the same information via podcast. Participants were randomized to receive a weight loss website (n = 20) or podcast (n = 20). Participants had skin conductance levels measured and completed questionnaire items assessing demographic characteristics, user control, novelty, and knowledge. Participants in the podcast group exhibited greater levels of physiological arousal and reported the intervention to be more novel than those in the Web group; however, the Web group reported greater user control. There was no difference in knowledge between the groups. This study presents the first step in examining the role that novelty and user control may play in two different weight-loss electronic media, as well as differences in knowledge acquisition. Future research should explore adding additional media features, such as video content, to the podcasts and websites in order to optimize fully the different mediums and to examine whether user control and novelty are potential mediators of weight loss outcomes.

Facilitating consumer clinical information seeking by maintaining referential context: evaluation of a prototypic approach.

Millions of consumers seek health information on the Internet. Unfortunately, this searching often falls short because of design limitations of many consumer-oriented Web sites. In this paper, we describe an approach that addresses several known barriers to consumer health information seeking. This approach primarily involves maintaining the referential context throughout a consumer's search for information. To maintain referential context, this approach uses multiple levels of hierarchical constructs to organize complex information, and data elements are toggled to minimize the need for scrolling. An information resource based on this approach was implemented for information about smoking using standard Web technologies. The resource was evaluated by 31 diverse consumers through standardized usability instruments. Consumers found the resource to be easy to navigate and to use. We conclude that the approach described in this manuscript could be applied more broadly to facilitate the organization and presentation of consumer health information.

"Let's Talk About Sex": pilot study of an interactive CD-ROM to prevent HIV/STIS in female adolescents.

The purpose of this study was to develop and pilot-test an interactive CD-ROM aimed at the prevention of sexually transmitted infections (STIs) in female adolescents. The CD-ROM includes prevention information, models skills for negotiating abstinence and consistent condom use, teaches media literacy, and allows the user to choose a culturally appropriate host to guide them through the CD-ROM. Forty-seven female adolescents attending a health department clinic were randomized to receive the CD-ROM plus an educator-led didactic session versus the didactic session alone. The CD-ROM was highly acceptable and feasible for use among female adolescents in the clinic setting. Hispanic and African American adolescents were more likely to choose hosts of the same race/ethnicity to guide them through the CD-ROM. HIV/STI knowledge increased significantly and nearly all adolescents intended to use condoms at next intercourse after viewing the CD-ROM. However, there were no significant differences measured between CD-ROM and comparison groups.
