    Correlating the effects of flow and telepresence in virtual worlds: Enhancing our understanding of user behavior in game-based learning
    (2013-05) Faiola, Anthony; Newlon, Christine; Pfaff, Mark; Smyslova, Olga
    Recent research on online learning suggests that virtual worlds are becoming an important environment to observe the experience of flow. From these simulated spaces, researchers may gather a deeper understanding of cognition in the context of game-based learning. Csikszentmihalyi (1997) describes flow as a feeling of increased psychological immersion and energized focus, with outcomes that evoke disregard for external pressures and the loss of time consciousness, issuing in a sense of pleasure. Past studies suggest that flow is encountered in an array of activities and places, including those in virtual worlds. The authors’ posit that flow in virtual worlds, such as Second Life (SL), can be positively associated with degrees of the cognitive phenomenon of immersion and telepresence. Flow may also contribute to a better attitude and behavior during virtual game-based learning. This study tested three hypotheses related to flow and telepresence, using SL. Findings suggest that both flow and telepresence are experienced in SL and that there is a significant correlation between them. These findings shed light on the complex interrelationships and interactions that lead to flow experience in virtual gameplay and learning, while engendering hope that learners, who experience flow, may acquire an improved attitude of learning online.

    The persuasiveness of humanlike computer interfaces varies more through narrative characterization than through the uncanny valley
    (2015) Patel, Himalaya; Pfaff, Mark S.; Ashburn-Nardo, Leslie; MacDorman, Karl F.; Šabanović, Selma
    Just as physical appearance affects persuasion and compliance in human communication, it may also bias the processing of information from avatars, computer-animated characters, and other computer interfaces with faces. Although the most persuasive of these interfaces are often the most humanlike, they incur the greatest risk of falling into the uncanny valley, the loss of empathy associated with eerily human characters. The uncanny valley could delay the acceptance of humanlike interfaces in everyday roles. To determine the extent to which the uncanny valley affects persuasion, two experiments were conducted online with undergraduates from Indiana University. The first experiment (N = 426) presented an ethical dilemma followed by the advice of an authority figure. The authority was manipulated in three ways: depiction (recorded or animated), motion quality (smooth or jerky), and recommendation (disclose or refrain from disclosing sensitive information). Of these, only the recommendation changed opinion about the dilemma, even though the animated depiction was eerier than the human depiction. These results indicate that compliance with an authority persists even when using a realistic computer-animated double. The second experiment (N = 311) assigned one of two different dilemmas in professional ethics involving the fate of a humanlike character. In addition to the dilemma, there were three manipulations of the character’s human realism: depiction (animated human or humanoid robot), voice (recorded or synthesized), and motion quality (smooth or jerky). In one dilemma, decreasing depiction realism or increasing voice realism increased eeriness. In the other dilemma, increasing depiction realism decreased perceived competence. However, in both dilemmas realism had no significant effect on whether to punish the character. Instead, the willingness to punish was predicted in both dilemmas by narratively characterized trustworthiness. Together, the experiments demonstrate both direct and indirect effects of narratives on responses to humanlike interfaces. The effects of human realism are inconsistent across different interactions, and the effects of the uncanny valley may be suppressed through narrative characterization.
