Here we propose a new design strategy for mixed and virtual reality designers, which we call ‘attentional transplants‘. The strategy is to direct a user's visual attention in a way which mirrors the attention of a previous user, in order to produce similar affective or cognitive responses in the second user. Attentional transplants may be useful across a wide range of design situations in which one's manner of attending reliably drives affective and cognitive outcomes. In order to test whether transplanting one participant's pattern of attention into another can produce similar downstream responses in the second participant, we ran two online experiments. In Experiment la, 50 observers viewed images of landscapes by using their cursor to move a small circular viewing window around each image for three seconds. After viewing an image, they rated how much they liked it. For each image, we identified two ‘attentional donors' - the Liked-it-Most observer who rated the image highest (standardized relative to their other image ratings) across observers, as well as the Liked-it-Least observer who rated the image lowest across observers. In Experiment 1b, we recruited 100 new observers to serve as ‘attentional recipients’. These observers viewed each image, but now passively, through a moving window which reproduced the viewing pattern of either the Experiment 1 observer who Liked it Most, or the observer who Liked it Least. Recipients gave substantially higher ratings to an image when they received the viewing pattern of the observer who Liked it Most, compared to when they received the viewing pattern of the observer who Liked it Least. Based on this success, we speculate about several additional ways in which attentional transplants could be used in virtual and mixed reality systems, in order to achieve desired cognitive and affective outcomes.
