Effects of visual and linguistic anthropomorphic cues on social perception,self-awareness,and information disclosure in a health website

Acknowledging the lack of studies examining both visual and linguistic anthropomorphic cues and the underlying mechanisms of their effects, we investigated how the different modalities of anthropomorphic cues in a health website influenced information disclosure. In a 2 (visual cues: human vs. non-human image) × 2 (linguistic cues: conversational vs. impersonal language) × 2 (question type: less vs. more sensitive questions) between-subjects experiment (N = 254), participants registered with a mock-up health website. We assessed a behavioral outcome of not disclosing personal information and psychological outcomes of social perception and self-awareness as potential mediators. Results revealed distinctive effects of the two modalities of the anthropomorphic cues. Anthropomorphic images, on one hand, increased public and private self-awareness, and public self-awareness in turn led to less information disclosure. Anthropomorphic language, on the other hand, heightened social perception and promoted information disclosure, but social perception did not predict the disclosure. These results indicate unique underlying mechanisms of the effects of anthropomorphism: priming effect of visual cues, and communicative effects of linguistic cues.

Simulated train driving: fatigue, self-awareness and cognitive disengagement

Fatigue is a serious issue for the rail industry, increasing inefficiency and accident risk. The performance of 20 train drivers in a rail simulator was investigated at low, moderate and high fatigue levels. Psychomotor vigilance (PVT), self-rated performance and subjective alertness were also assessed. Alertness, PVT reaction times, extreme speed violations (>25% above the limit) and penalty brake applications increased with increasing fatigue level. In contrast, fuel use, draft (stretch) forces and braking errors were highest at moderate fatigue levels. Thus, at high fatigue levels, errors involving a failure to act (errors of omission) increased, whereas incorrect responses (errors of commission) decreased. The differential effect of fatigue on error types can be explained through a cognitive disengagement with the virtual train at high fatigue levels. Interaction with the train reduced dramatically, and accident risk increased. Awareness of fatigue-related performance changes was moderate at best. These findings are of operational concern.     

Avatar-driven self-disclosure: The virtual me is the actual me

Considering the importance of self-disclosure in building relationships and bonds, it is vital to investigate how self-disclosure is affected by avatars utilized in many online communities. In this study, we tested a research model that explores how perceived avatar-self similarity affects self-disclosure via different theoretical constructs such as self-awareness, self-presence, and identifiability. The research model was empirically tested with data from a web-based survey of 209 Second Life users. Results revealed that avatar similarity impacts self-disclosure but with varying effects, depending on how it is mediated by variables of identifiability, self-awareness and self-presence. Specifically, appearance similarity affects homophily, which heightens self-awareness. This results in increased feelings of self-presence, which positively affects self-disclosure. Homophily also has the effect of heightening perceptions of identifiability, which decreases self-disclosure. Implications and applications are discussed.     

Deception in avatar-mediated virtual environment

This study explored the effects of avatars on deception – how perceived avatar likeness to self can affect the truthfulness and accuracy of interactions online. More specifically, this study examined the extent to which perceived avatar similarity influences self-awareness and users’ degree of attraction to them, and how these psychological states affect deception in the context of Second Life. The results, based on web-based survey data of 159 Second Life users, revealed that avatar similarity in attitude and behavior to the owner heightened self-awareness, which, in turn, reduced deception. Perceived avatar similarity in terms of appearance was found to have a direct negative impact on deception so that those who perceived their avatars to look similar to themselves were less likely to engage in deceptive behavior. Implications of the findings are discussed.     

The effects of self-awareness on body movement indicators of the intention to deceive

A study was conducted to investigate the body movements of participants waiting to be interviewed in one of two conditions: preparing to answer questions truthfully or preparing to lie. The effects of increased self-awareness were also investigated, with half of the participants facing a mirror; the other half facing a blank wall. Analysis of covertly obtained video footage showed a significant interaction for the duration of hand/arm movements between deception level and self-awareness. Without a mirror, participants expecting to lie spent less time moving their hands than those expecting to tell the truth; the opposite was seen in the presence of a mirror. Participants expecting to lie also had higher levels of anxiety and thought that they were left waiting for less time than those expecting to tell the truth. These findings led to the identification of further research areas with the potential to support deception detection in security applications.     

Constraints on message size in quasi-synchronous computer mediated communication: Effect on self-concept accessibility

Anonymity is often regarded as a variable of great importance in research on computer mediated communication. However, this view might neglect the role played by the design of the user-interface. The current study attempted to show the effects of manipulation of the user-interface in terms of quantitative aspects of communication and self-concept accessibility. The manipulation consisted of varying the number of characters available to interlocutors in two conditions. It was predicted that different designs will not only influence communication quantitatively, but also to what degree participants are able to introspect and strategically plan communication in a self-presentation task. The design that allowed elaborate composition of a message during communication was expected to lead to more strategic self-presentation, thus increasing availability of the “actual self”. Two experiments were conducted. The results show that constraints on communication are associated with predictable quantitative effects, among them higher turntaking. Also, accessibility of the actual self appears to be associated with less interactive and involving interfaces. The results are discussed with regards to the Social Identity Model of Deindividuation Effects, as well as the differences between writing and speech.     

Virtual world continuance intention

Virtual worlds face stiff competition and the threat of a high user attrition rate. While considerable research has investigated factors for continued use of virtual worlds, there has been little attention on how users’ embodiment in virtual worlds (i.e., avatars) affect this important cognitive decision. We developed a research model drawing on self-awareness theory and presence, to explain how user continuance intention may be influenced by avatars, in particular self-similar ones. Through a survey with 209 virtual world users, we tested our research model using structural equation modeling. Results indicate that avatar-self similarity positively affects continuance intention through self-awareness and self-presence. The findings verify that avatar characteristics influence post-adoption behavior and emphasize the importance of user autonomy in design.     

The extended ‘chilling’ effect of Facebook: The cold reality of ubiquitous social networking

Prior research has established the phenomenon of the ‘Chilling Effect’ where people constrain the self they present online due to peer-to-peer surveillance on Social Network Sites (SNS). However currently uninvestigated is the possibility that the threat of such surveillance on these sites might constrain the self presented offline in ‘reality’, known here as ‘the extended chilling effect’. The purpose of this study is to examine the existence of this ‘extended chilling effect’. Drawing on theories of self-awareness and self-presentation, the impact of surveillance in SNS is theorized to lead to an awareness of online audiences in offline domains, stimulating a self-comparison process that results in impression management. A mixed methods study of semi-structured interviews (n = 28) and a 2 × 2 between-subjects experiment (n = 80), provides support for offline impression management in order to avoid an undesired image being projected to online audiences. The novel finding that the chilling effect has extended highlights the potential dangers of online peer-to-peer surveillance for autonomy and freedom of expression in our offline lives.     

Crash risk of older drivers after attending a mature driver education program

PURPOSE: The primary aim of this study was to determine if the crash rate of aging drivers can be mitigated by post-license driver education. DESIGN AND METHODS: This study of 884 older drivers who attended the 55 Alive/Mature Driving program was conducted in three phases. Phase 1, which examined self-selection bias of seniors attending the driver education program, and Phase 2, which examined changes in crash rate after attending the program, were carried out through analysis of driving records before and after attending the course. In Phase 3, the use of selection, optimization, and compensation strategies by older male drivers who attended 55 Alive/Mature Driving was addressed through focus group interviews. RESULTS: Findings showed a self-selection bias among older drivers who attended 55 Alive/Mature Driving. Results also showed attendance at the program was associated with an increased number of crashes for men aged 75 years and older, but no effect on subsequent crashes of younger men and women of all ages. Focus group sessions suggested older men who attended the program used fewer strategies to cope with their declining skills. IMPLICATIONS: Recognizing and understanding characteristics and behaviors of older drivers who attend remedial driver education is essential to the design and delivery of successful driver safety programs.
