In psychology research studies, the goals of the experimenter and the goals of the participants often do not align. Researchers are interested in having participants who take the experimental task seriously, whereas participants are interested in earning their incentive (e.g., money or course credit) as quickly as possible. Creating experimental methods that are pleasant for participants and that reward them for effortful and accurate data generation, while not compromising the scientific integrity of the experiment, would benefit both experimenters and participants alike. Here, we explored a gamelike system of points and sound effects that rewarded participants for fast and accurate responses. We measured participant engagement at both cognitive and perceptual levels and found that the point system (which invoked subtle, anonymous social competition between participants) led to positive intrinsic motivation, while the sound effects (which were pleasant and arousing) led to attentional capture for rewarded colors. In a visual search task, points were awarded after each trial for fast and accurate responses, accompanied by short, pleasant sound effects. We adapted a paradigm from Anderson, Laurent, and Yantis (Proceedings of the National Academy of Sciences 108(25):10367-10371, 2011b), in which participants completed a training phase during which red and green targets were probabilistically associated with reward (a point bonus multiplier). During a test phase, no points or sounds were delivered, color was irrelevant to the task, and previously rewarded targets were sometimes presented as distractors. Significantly longer response times on trials in which previously rewarded colors were present demonstrated attentional capture, and positive responses to a five-question intrinsic-motivation scale demonstrated participant engagement.

Purpose of Review The goal of this paper was to provide a narrative review of human factors considerations for telemedicine. It also sought to provide readers a foundation of human factors thinking and methods that could be employed within their own practice. Recent Findings There are only a handful of articles that discuss the importance of user-centered design and human factors principles in relation to telemedicine systems. Summary Most articles come to the conclusion that design flaws could have been avoided by involving stakeholders in the design and implementation of telemedicine. However, many of them lack the guidance for those who find themselves having to choose, implement, or use unwieldy systems. With this in mind, this paper provides a series of human factors principles, realworld questions, methods, and resources for those who may find themselves considering, implementing, sustaining, or using telemedicine in their own healthcare settings.
