An Experimental Study on Emotional Reactions Towards a Robot

Although robots are starting to enter into our professional and private lives, little is known about the emotional effects which robots elicit. However, insights into this topic are an important prerequisite when discussing, for example, ethical issues regarding the question of what role we (want to) allow robots to play in our lives. In line with the Media Equation, humans may react towards robots as they do towards humans, making it all the more important to carefully investigate the preconditions and consequences of contact with robots. Based on assumptions on the socialness of reactions towards robots and anecdotal evidence of emotional attachments to robots (e.g. Klamer and BenAllouch in Trappl R. (ed.), Proceedings of EMCSR 2010, Vienna, 2010; Klamer and BenAllouch in Proceedings of the 27th International Conference on Human Factors in Computing Systems (CHI-2010), Atlanta, GA. ACM, New York, 2010; Krämer et al. in Appl. Artif. Intell. 25(6):474–502, 2011), we conducted a study that provides further insights into the question of whether humans show emotional reactions towards Ugobe’s Pleo, which is shown in different situations. We used a 2×2 design with one between-subjects factor “prior interaction with the robot” (never seen the robot before vs. 10-minute interaction with the robot) and a within-subject factor “type of video” (friendly interaction video vs. torture video). Following a multi-method approach, we assessed participants’ physiological arousal and self-reported emotions as well as their general evaluation of the videos and the robot. In line with our hypotheses, participants showed increased physiological arousal during the reception of the torture video as compared to the normal video. They also reported fewer positive and more negative feelings after the torture video and expressed empathic concern for the robot. It appears that the acquaintance with the robot does not play a role, as “prior interaction with the robot” showed no effect.

Investigations on empathy towards humans and robots using fMRI

Although robots are starting to enter into our professional and private lives, little is known about the emotional effects they elicit. In line with the Media Equation, humans may react towards robots as they do towards humans, making it all the more important to carefully investigate the preconditions and consequences of contact with robots. Based on assumptions on the socialness of reactions towards robots, we conducted a study that provides further insights into the question of whether humans show emotional reactions towards a robot and whether these reactions differ from those towards a human. To explore emotionality in human-robot interaction we conducted an fMRI study (n=14). Participants were presented videos showing a human, a robot and an inanimate object, being treated in either an affectionate or in a violent way. Self-reported emotional states and functional imaging data revealed that participants indeed reacted emotionally when seeing the affectionate and violent videos. While no different neural activation patterns emerged for the affectionate interaction towards both, the robot and the human, we found differences in neural activity when comparing only the videos showing abusive behavior indicating that participants experience more emotional distress and show negative empathetic concern for the human in the abuse condition. This was supported by similar findings with regard to participants self-reported emotional states.

Neural correlates of empathy towards robots

We conducted an fMRI study to investigate emotionality in human-robot interaction. Subjects (N=14) were presented videos showing a human, a robot and an unanimated object, being treated in either an affectionate or a violent way. Violent interaction towards both the robot and the human resulted in similar neural activation patterns in classic limbic structures indicating that both the robot and the human elicit similar emotional reactions. However, differences in neural activity suggest that participants show more negative empathetic concern for the human in a negative situation.

Do 3d moviegoers enjoy screenings more than 2d moviegoers?-on the impact of 3d fantasy movie perception on enjoyment

As 3D movie screenings have recently seen an increase in popularity, it would appear that 3D is finally ready to stand the test of time. To examine the effect of 3D on the experience of enjoyment, we refer to the model of entertainment by Vorderer, Klimmt, and Ritterfeld (2004), according to which both technological and personal prerequisites can induce enjoyment. The model was further adapted for the cinema context by including the appeal of special effects, fanship, age, and gender. To ascertain the impact of the suggested prerequisites, we conducted a field study comparing the enjoyment experiences of 2D and 3D audiences watching the same fantasy movies in a between-subjects design (N = 289). Results showed that the technological features of stereoscopic 3D cannot predict enjoyment. However, the feeling of presence, the appeal of the special effects, and fanship are predictors of enjoyment.

Being Bullied in Virtual Environments: Experiences and Reactions of Male and Female Students to a Male or Female Oppressor

Bullying is a pressing societal problem. As such, it is important to gain a better understanding of the mechanisms involved in bullying and of resilience factors which might protect victims. Moreover, it is necessary to provide tools that can train potential victims to strengthen their resilience. To facilitate both of these goals, the current study tests a recently developed virtual environment that puts participants in the role of a victim who is being oppressed by a superior. In a 2 × 2 between-subjects experiment (N = 81), we measured the effects of gender of the oppressor and gender of the participant on psychophysiological reactions, subjective experiences and willingness to report the event. The results reveal that even when a male and a female bully show the exact same behavior, the male bully is perceived as more threatening. In terms of gender of the victim, the only difference that emerged was a more pronounced increase in heart rate in males. The results were moderated by the personality factors social gender, neuroticism, and need to belong, while self-esteem did not show any moderating influence.

What Is Beautiful in Cyberspace? Communication with Attractive Avatars

The face with its structural and nonverbal features is the most important cue in interpersonal face-to-face communication e.g. Dion et al., 1972; Reis et al., 1990. The aim of the presented study is to examine whether physical attractiveness and nonverbal cues in virtual representations can elicit interpersonal effects comparable to those evoked in face-to-face contacts. In a 2 observers nationality x 2 smiling, non-smiling x 3 senders attractiveness x 2 senders gender x 2 observers gender experimental design 158 German and 128 Malaysian participants evaluated 18 faces 9 smiling, 9 non-smiling concerning attractiveness, social competence and dominance. Analyses show several effects, e.g. indicating that the same facial features are attractive in virtual faces and human faces.
