Abstract
Research on level 1 visual perspective taking (L1-VPT) has been debating whether L1-VPT is an implicit socially rooted or rather a non-social process. Using online versions of the Dot Perspective Task by Samson et al. (Journal of Experimental Psychology: Human Perception and Performance, 36(5), 1255-1266, 2010) we approached this question by comparing L1-VPT for robot vs. human avatars. In line with the assumption that visual perspective taking is due to mentalizing, we predicted that perspective taking, leading to altercentric intrusions, should occur more strongly for the human avatars than for the robot avatars. In two experiments, a within-participant design was applied: 2 (avatar: human vs. robot) × 2 (avatar perspective: consistent vs. inconsistent) × 2 (task: avatar perspective vs. self-perspective). The human avatar was a male in Experiment 1 (n = 120) and a female in Experiment 2 (n = 113). The analyses of reaction times and error rates showed significant, medium to large egocentric intrusions and significant, small to medium altercentric intrusions for both avatar types, suggesting interference from the irrelevant perspective. Against the prediction, the altercentric intrusions for human avatars were not significantly larger than for robot avatars. Taking into account methodological concerns and suggesting future experimental variations, we argue that the submentalizing approach assuming that visual perspective taking is based on domain general processes provides a good explanation for our results.
